Thank you for your suggestions. The IT admin is on vacation this week but when he comes back we will try some things.

Take a look at the Web Connection install instructions - it shows the dialog that you should be looking at. ASP.NET is one of the 'recommended' components with Web Connection now that the .NET module is supported and you can see that in the setup instructions for Win7/Win2008.

wcdocs:_22f0xkbmq.htm

Your roles will determine what gets installed - they can override the settings in the features dialog.

Other than that I don't know. Win 2008 ships with .NET 3.5. You'll probably want to install .NET 3.5 SP1 since it includes many new features and framewqork enhancements.

\Sorry I somehow clicked on Send before finishing the message

Rick,
One more question, please (actually more than one). I connected to the customer Server 2008. Here is what I see:
Program & Features Installed:
1. Microsoft .NET Framework 3.5 Sp1
2. MSXML 4.0 SP2
3. MSXML 4.0 SP2
4. Vmware Tools

Then I looked at the Role Services:
Application Development Not Installed
ASP.NET Not Installed
.NET Extensibility Not Installed
ASP Not Installed
CGI Not Installed
ISAPI Extensions Not Installed
ISAPI Filters Not Installed.

My quetions is, do I ask the IT manager to install the above Role Services? What is confusing to me is that the Feature sections shows that .NET 3.5 is installed but the Rose Services is not. Microsoft tech writers need a vacation (or I do <g>).

Thank you in advance for your help.

Make sure ASP.NET is installed (Windows Features) first of all. By default it is not.

Next make sure that the ISAPI and CGI restrictions are set to allow ASP.NET. Go to the server machine root and use ISAPI and CGI Restrictions and allow ASP.NET there.

Finally make sure your application is set to run in the appropirate ASP.NET application mode (Integrated is what you typically want).

Hope this helps,

Hello,

I am trying to install an ASP.NET application (ver 2.0) on Server 2008 (IIS 7) for the first time.

When attempting to browse a very simple (one line) .ASPX page I get the following error:

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

I don't think I need MIME map but one other possible cause of the problem (as shown on the error page) is that ASP.NET is not installed. I checked the local services on the server but see nothing that resembles ASP.NET service. I checked the folder C:\Windows\Microsoft.net\Framework and the folders for .NET 2,3 are there.

How do I verify if ASP.NET is or is not installed? On IIS 6 I remember executing "ASPNET_REGIIS –i" in command prompt. But I don't know if this can cause adverse effects on the Server 2008 (customer server).

Any suggestions, please?

This is the latest downloaded from the link you provided this morning.

Make sure you have the latest version of the generator - there were some updates to the functionality to support imported WSDL sub documents (as WCF in .NET produces). It sounds like that's not happening in your case...

FWIW I used to see these problems on my server occasionally, prior to the Server 2008 update, but haven't seen them since. However, in the past I was running Interactive account whereas now I run with a specific Admin account and no logon so that's likely the real issue.

My guess is it's a permissions issue of some sort where the system is trying to start up IIS when the permissions and logons aren't properly setup. The permissions then cache and continue to fail the process in question until restarted once the system is up and running.

As I said I don't see this anymore on Server 2008, but that's no guarantee that in other environments it may not still be an issue. It's a startup timing issue for sure and as such difficult to pinpoint because almost every system is configured differently.

+++ Rick ---

Reviving an old post (again) - unfortunately it remains relevant as we continue to encounter this issue. We're up to nearly 200 installations of our web connect app and only a handful have reported these errors, and in most cases they show up when rebooting, then go away as things "settle in". I'd be inclined to ignore it entirely except that we've had to instances in the past 3 months where it apparently brought our entire application down. Things would be working fine, then suddenly any hit on wc.dll would get no response and eventually time out. We were able to get things going again after rebooting/restarting IIS (relying on secondhand info from the sysops so can't report the exact sequence). One incident was from last December - things seem be working since then. The other happened this morning so I'm hoping for a similar outcome...

One question - has anyone run into this under Server 2008? All cases we've encountered have been running 2003 - I'm wondering if it's safe to suggest a server upgrade as a solution if problems persist for a given client? (From Rick's earlier posts on this it's clear that nobody at M$ was inclined to fix anything under the older OS but I'm hoping that maybe things are better with the newer product.)

--stein

One of my clients is reporting a series of IIS Worker Process errors after rebooting. The faulting application is w3wp.exe and the faulting module is wc.dll, which prompted him to call me. He gets a few of these during the reboot process, then again the first couple of times we hit a wc link (along with a Service Unavailable message in the browser). Then magically things start to work.

But as soon as we reboot we get another string of errors.

He claims this just started happening today, and I don't recall ever seeing this error on any of our 100+ client systems, so I was rather weirded out when I logged onto one of my servers a bit later and encountered the exact same message (also pointing to a problem with wc.dll...) In my case at least, there was just one message and nothing showed up after I rebooted. (In both cases we're running WC 5.33 under Win 2003.)

I checked the MS hotfix status - doesn't appear they pushed anything out last night though they did put out a security patch a week ago.

Just wondering if anyone else has run across this recently.

If that is indeed what is happening, what is the solution/alternative? Thanks.

- Aashish

The POST buffer is a stream in IIS and it's read on demand. AFAIK it's forward only - once read there's no way to go backwards to read values again. So if an ASP.NET module early in the request cycle reads the POST buffer as a full stream another tool like ASP won't see the request stream.

Other ASP.NET componenets will see POST values just fine since those get set very early in the pipeline but if you read the stream (and modify it as you are trying to do) you are touching the raw stream and that's forward only.

+++ Rick ---

Thanks for your prompt response.
Yes, this is accomplished in IIS 6 using wildcard application mapping.

I'm not sure if I follow(/agree with) your explanation about the Request object being cleared out as it is read. I thought that the HttpModule is a part of the Request pipeline and therefore, has access to all events of the Request's life-cycle, even more so in IIS 7 when running in integrated pipeline mode, where the ASP.NET request pipeline is integrated with the Web server's Request pipeline.

Please let me know if I missed something.

- Aashish

Client has a Classic ASP application hosted on IIS 7 running in Integrated Pipeline mode. An ASP.NET based HttpModule registered on the IIS application attempts to prevent cross-site scripting attacks. The classic ASP application works fine (without the cross-site scripting attack filter functionality). But as soon as this HttpModule is added to the IIS 7 application, the Request object clears out after an HttpRequest is POSTed from the classic ASP application.

BTW, this same implementation works fine on IIS 6. The code in the HttpModule is listed below, if it helps.

Uhm, how are you getting this to work on IIS 6? With wildcard mappings?

Both ASP and ASP.NET will reasd the post buffer and clear it as it is read since it's being read directly from the inbound IIS stream. Once read the POST buffer is gone. So if you read in ASP.NET then ASP isn't going to get POST data and vice versa AFAIK.

Any ideas, please? Thanks.

I want to execute some Java script to call a method on the server to update a record, much like the DeleteCustomer example where the list is refreshed by using Java to fadeout the affected record and the entire page does not need posted back--this is very sweet (BTW).

However, instead of deleting the record via a link, I want the user to be able to select a status from a selection / list. If the status changed, I want to remove the record from the list using JS.

I've tried this for a couple of days now using the onchange event attribute. I am able to get this to work with a link, but not with a SELECT tag.

Please help.

Thanks - there was a little note on this in the wiki page for VFP9 runtimes. It appears that moving msvcr71.dll to the {sys} directory (Even though M$ suggests otherwise) in my setup resolved the problem.

Hi Michael,

What is the error code?

I've not tried this on 64bit Win7 so I'm not sure if there are any problems.

You probably know this but its worth checking. . .

One quirk with this runtime is that it requires the MSVCR71.dll. This dll got demoted from being a system library and documentation states to put it in your application directory. Now I would do this but the result is the runtime will not register. You either need to put a copy of MSVCR71.dll in with teh vfp9r.dll or just have done with and shove it in the System32 (or 64 bit equiv) folder.

HTH

Richard

Hi Rick,

No its ok I was expecting someone to suggest it. I face the age old problem of not being able to convince a customer to upgrade. I have used SQL CLR integration with great success and it is a pleasure to work with. Unfortunately I'm forced to do this. I have done this with VFP MTDLLS with no problems over a long period of time. Its just I need to use .NET for some of the framework libraries with will speed up development.

Now I did consider using a VFP COM server and calling into .NET via COM but the performance and other potential issues of this just seems nasty. I just cannot see the point if I can call into .NET via COM directly.

I am planning to keep this class as simple as possible, but I need to know whether .NET COM servers support SQL's COM threading model. I think it will work fine, but I need to work out if I should make the code thread safe and if so whats the best way to do this in my class without causing unecessary blocking issues. Once I've established this I will be happy to proceed and look to a brighter future of SQL CLR integraion <g>

Thanks

Regards

Richard

Not to sound snippy, but if you want to integrate .NET code into SQL Server why don't you upgrade to SQL 2005 or later that has native .NET support? You'll get much better performance, integration and most important stability and security.

Putting COM into any multi-threaded environment if you can avoid it is a disaster waiting to happen :-}...

+++ Rick ---

Hi all,

I think I find I'm OK.

It appears that sp_OA calls in SQL Server are created on seperate threads that make there own calls to OleInitialze() (essenitally putting these threads in their own STA). There is a main STA which keeps a reference count per thread STA created. So as .NET COM classes are set to Both my class will be put in STA allowing SQL server direct access to the class on one thread per STA. As SQL supports multiple STA's there will not be any real issues with blocking so I do not need to worry too much about this. Am I making the correct assumption here?

Also, as .NET classes can be placed in an MTA does that mean from now on I need to ensure thread safety to some degree? I don't normall check for MTA when I assume an app is not concurrently using my class. Of course this could be a mistake if the process uses multiple threads in a single MTA to access my object(s). Do I need to cater for this with my own thread synchronisation and is this best practice for C# COM classes anyway?

TIA

Richard

Hi all,

I have built COM classes in C# before either using ClassInterfaceType.AutoDual for automatic late and early bound type exports and ClassInterfaceType.None to explicitly specify an interface for my class. The later I use for versioning and to implement COM events.

Typically I have used these COM classes in VFP, called via VFP's single threaded model, and have not worried about threads or COM apartments. I now have a scenareo where I want to expose a .NET COM Class to SQL Server 2000 which I want concurrent use of my class. I assume that SQL server will use multiple threads to call my class but I am unsure if it sets its threads to be in an STA or MTA?

I assume my .NET COM classes are STA?? Now if SQL Server is MTA, ideally I would want to make my class MTA to avoid marshalling, but would I then have to handle thread synchronization within my COM methods? Can I even make my C# based COM class MTA?

If my understanding of this is correct. . . If I have an STA I assume that any calls from other threads during a call from another thread will block until the first thread is complete? Is this correct? I know that MTA is marshalled to STA in this way which causes blocking. Basically will an STA block calls from an STA and MTA with multiple threads calling the COM object?

Looking at the COM registration in the registry the class is actually using mscoree as a proxy to my .NET class. Its threading model is set to BOTH which means the apartment type is determined by the caller. In which case how does mscoree handle this? Does I not have to worry about this?

I must sound rather confused, and that is because I am <g>. I got some grounding on the theory but not a firm enough grasp to take things forward. I just want to create a COM class that works efficiantly with SQL Server with the possiblility of avoiding:

1) COM Apartment Marshalling causing bad performance.
2) Blocking, effectively causing bad peformance.
3) Race conditions, deadlocks due to lack of thread safety.

Can anyone offer any advice, tips or point me to an example anywhere?

TIA

Richard

Rick,

That got the configuration program running. Thanks. However, I've still got to figure out why the admin web page won't show up. I'll keep working on this for a bit to get my bearings on .net.

Yes you need to enable Metabase IIS 6 compatibility in the IIS configuration...

Go to Windows Features, find IIS and enable the IIS 6 Metabase Compatibility in the feature list...

Rick,

IIS is running -- i checked this with a static page. It looks like the issue according to the error code is something to do with interop services. Here's the exception text:

The store runs .NET 3.5, but this shouldn't bomb the installer.

Make sure IIS is installed and running tho. That's the more likely culprit for crashing.

VS 2010 should work fine - It'll just try to upgrade the project files which should be fine...

+++ Rick ---

Hi Rick,

I am trying to install the .net store code on my windows7 o/s along with VS2010. I noticed in the documentation and VS2008 is supported...should VS2010 be okay too?

I am having trouble getting the website configuration application to run. It craps out with various errors when first loading. I loaded up the .net 2.0 framework SDK thinking this might be the problem but it still gives the same error. It also says the distributable .net 2.0 framework was installed automatically with the o/s. Any ideas are much appreciated. Thanks.

Russell -

However, with another client's server (Win2K3 64-bit), that solution does not seem to be working. So I'm wondering if my memory of what solved the issue is incorrect or if this is a 64-bit issue.

We have not yet used Cryptor on a 64 bit OS yet, although we do have a client using Cryptor who is wanting to move to 64 bit, so I expect we'll be testing this out pretty soon.

- Mike McDonald

I resolved this on one client's server (Win2K3 Std. Edition) by putting MSVCR71.DLL and MSVCP71.DLL into the same folder with the application's EXE (and the Cryptor files). At least that's the way I remember it and looking at their setup now, it seems to reinforce that memory (but shame on me for not making some notes about it).

However, with another client's server (Win2K3 64-bit), that solution does not seem to be working. So I'm wondering if my memory of what solved the issue is incorrect or if this is a 64-bit issue. Anyway, if anyone has any more info on this, I'd appreciate it.

Also, if you need the c40fox90.fll file, I'll be glad to send it to you.

Russell Campbell

Bruce -

Did you ever get a resolution to this? We have been using Cryptor for years and just recently are getting this same problem on Windows Server 2003. "c40fox90.fll in invalid"

Here are the filenames found in some of my notes from when I was having problems with this..

XICRCORE.DLL must exist in the executable launching folder.

msvcr71.dll (or possibly msvcr70.dll and/or mscvrt.dll?) needs to be in \Windows\System32.

The VFP runtime files must be available, including VFP7T.DLL (or VFP9T.DLL in your case?). We're using C40fox70.fll, which is specific to VFP 7. Your filename of C40fox90.fll seems to indicate VFP version 9. If that is the case, do you know you got that version (and how I could get it)?

Hi Mike,

Bruce Anderson

Hi Mike

XICRCORE.DLL is in the application launch folder. c40fox90.fll is in the parent folder though and it is referenced in the code as "SET LIBRARY TO ..\c40fox90.fll". Thanks for pointing that out; I will try putting both files in all places (parent, launch, %system% paths).

MSVCR71.DLL and the like are all installed as part of our application because they are required for VFP. We use the .msm files supplied.

From memory I contacted Xitech directly when vfp9 came out and they supplied an alternative to the c40fox70.fll which we previously used. As far as I know this is just a change in the check to ensure the .fll is being used with a compatible version of VFP. I think we paid about £25.00 for it. Getting hold of someone there seems to be next to impossible now. In my opinion looking at the pricing structure on QBS these days Xitech are taking the p!&s a bit, so good luck.

Steve W

Steve -

I think you are OK with your VFP Project settings - that seems about the same as what I have.

You might want to make sure that XICRCORE.DLL is in the application's launch folder (instead of \Windows\System32).

Also, I believe that msvcr71.dll (or possibly mscvrt.dll?) needs to be in \Windows\System32.

Based on the c40fox90.fll filename (and previous versions), that sounds like this would be used with VFP 9. Is that the case? I wasn't aware that Cryptor would work with VFP 9 (their site still doesn't indicate this). That would be really good to know if this was possible.

- Mike McDonald

Hi Richard,

Thanks for replying. The actual message is generated from within VFP and is "Library file c40fox90.fll is invalid" (Based on error 1691, "Library file 'name' is invalid"). I know that c40fox90.fll is another way to call XiCrCore.dll, which as I understand does all the actual work. Both these files are shipped with the application and are present.

c40fox90.fll is known to the project file but set as excluded. XiCrCore.dll is not known to the project file. I don't think the project has anything to do with the error on the basis that the application works fine on 1000's of other installs (literally).

Googling this has proved pretty fruitless so any thoughts are welcome.

Steve W

Hi Stephen,

The error getting generated, is it a vfp error? As your using an FLL you have to make sure you have included it within your project. When compiling exe's in VFP that reference FLL's you need to make sure the FLL is part of the project. Even if the file is distributed the exe the code will not be able to load the library if the FLL was not part of the project at compile time.

If I'm off the mark here; have you got any more details of the error? Things such as the exact library missing?

Regards

Richard

Has anyone experienced any problems with the file C40Fox90.fll supplied from Xitech? And more importantly got a fix?!

I currently have two PC's at different sites that produce a "Library File is Missing / Invalid" message upon attempting to SET LIBRARY TO. One PC is Windows 2003 Server (New Dell Server), and the other XP Pro (SP2). The application works fine on other W2K3 Servers and XP Pro installs.

Xitech state on their site that there are no dependancies for the assocaited .dll (which I think is XiCrCore.dll). Running DependancyWalker on the file lists loads of other .DLL's which look pretty standard.

TIA

Several problems with your code: events should have no JavaScript tag (and it needs to be javascript all lower when you do use it). Additionally your first parameter needs to be in quotes.

onchange="DispChange('_2xadasadsas',event);"

FireBug or the IE Script debugger are your friend - they will show you the errors in your page code or when page is executed and fails - otherwise these errors fail silently which is highly undesirable.

However I would recommend that you dynamically load the drop downlist only when needed rather than rendering it into the page for each item (unless each item has different options) to avoid page bloat due to duplication.

Hi Charles,

You can't directly retrieve the text value from a text box - only the value is available. If you need the text value you need to look it up in the table based on the key you retrieved...

Web Connection doesn't keep a list of list items for any of the list controls (which is unlike ASP.NET) because of performance and memory concerns in VFP - there's tremendous overhead in creating new lists and keeping them in memory compared to rendering directly from the data source.

The data source should be open after selection - so a lookup for the value should be pretty easy to do.

+++ Rick ---

I have a drop down that lists valid gl account numbers.
the display text is the account name (Accounts receivable) while the selected value is the account number (12345-0000)

I can assign a value from a drop down list with
this.sa4.text=this.sl1_list.SelectedValue (12345-0000)

I need to assign the accoumnt name to another text object.
this.sl4.text=this.sl1_list.? (Accounts Receivable)

Cannot seem to find the correct tag

Charles

There's an example in the samples that feeds jqGrid data - but it returns JSON data. It's a funky format that it expects...

+++ Rick ---

BTW, you can also use a Callback handler completely generically if you pass in your parameters as POST or QueryString values by specifying:

MyHandler.ashx?Method=MyCallbackMethod

which is a great way to build a generic POX service. Simply add methods to the handler, add the ReturnAsRawString parameter to CallbackMethod() and you have a very easy way to have a single class that handles many operations and can return either raw data or JSON.

Just used this for a customer implementation and it's a huge time saver!

I'm actually using it for jqGrid right now. Well, I'm using both the JSON and (now that I found out how to) raw data. No XML yet but it's nice to be able to handle it all without having to have multiple handlers.

In ASP.NET applications you should never use a ResourceManager. You'll end up duplicating the resources loaded...

Use HttpContext.GetGlobalResourceObject() or HttpContext.GetLocalResourceObject() to retrieve resource values anywhere in an ASP.NET application to ensure you're using the right resource provider that is serving the rest of the application resources.

Hi Rick,
I stuck in middle of my implementation as my requirement is to get value of certain dynamic control to be bind from code behind or just for any control if i don't use meta key and would like to bind the value from code behind,how this could be done.
I tried to use in this way but this don't work.
System.Resources.ResourceManager resource = new System.Resources.ResourceManager(typeof(MeasureControl));
btnPri.Text= resource.GetString("btnPri.Text");
I also tried to call getobject("btnPri.Text") but this approach dont work as this expect resource file to be available,Please help me how can i get resource-id value using resource-id,culture from code behind.

During my testing and learning I have encountered the message

"Welcome to West Wind Internet Protocols
