How to debug classic ASP pages in VS 2005

Hi, Mikhail

It is somewhat not related to the topic, but I have some questions regarding VS2005 and the new asp.net 2.0 model. (I'm in the middle of conversion of the big project from 1.1 to 2.0)

1) server controls inside user controls (for example dropdownlist). Because of the new model I can not declare it in the code behind, they are already declared as protected from aspx code.

In asp.net 2.0 I had some of these controls declared as public in order to have access from the outside. Now they are all protected, so it gives compilation errors. Is there any elegant way to solve this ?

The simples way is to declare a public property that returns the inner control instance. However, when I am thinking that I need to declare an accessor method or property, I always stop and think if the code is structured right. Accessor methods that give access to otherwise private or protected members are often just hacks. Certain code restructuring may eliminate necessity to access protected members. Of course, it is not always possible.

What about steps
5)Debug | Attach to Process and
6)Locate IIS ASP worker process (w3wp.exe on IIS6) which exposes x86 and Script and attach as Script

Can you describe the details to carry out these actions?

Thanks

You access Attach to Process command in the Debug menu. It display a window with all processes running in OS that you can attach to. One of the processes will be w3wp and type of code will be x86 and Script. Select the process and at the top of the dialog choose Script instead of Automatic. Click Attach.

I'm trying to debug classic ASP in VS 2005 and have tried everything to get it to work. I open the web site as a web project. Then when I do Debug.StartWithoutDebugging it runs the web site from //localhost and everything looks good. But I cannot attach to the ASP.NET worker process because it's not running. No matter what I try, the worker process doesn't run which seems to make sense because the pages are ASP not ASP.NET. Any ideas on why this is happening or what I can try? Thanks.

You need to attach to ASP worker process, not ASP.NET process.

If this is true, then how on earth can you now debug code in the application startup event in classic ASP ?

You can't attach to the w3wp.exe process when you application startup code it running so you have run it from a project in VS.NET 2003. Are you saying there is therefore now not a way to debug the startup event ?

FYI -
When running on XP Pro/IIS 5, you need to attach to dllhost.exe instead of w3wp.exe. You may have more than one instance of dllhost running on your machine, so look for the one with Type "Script, x86" and the User Name column indicates your IIS process account (IWAM_machinename).

I have a clarification. I used to debug ASP application in VS 2003. I shut down the system and the next day, when I tried to Debug Process, it gave me an error.
---------------------------
Microsoft Development Environment
---------------------------
Processes cannot be displayed. Access is denied. Verify that you are an administrator or a member of the 'Debugger Users' group on the machine you are trying to debug. After being added to the 'Debugger Users' group, you must log off and log back on for the setting to apply.
---------------------------
OK
---------------------------

Can you help me on this? My account is administrator account and is added in "Debugging users" group.

Thanks.
Arun

Hi Mikhail,

I can attach to the worker process (dllhost Script x86) but it clearly is not fully attached, as break point are never activated, and even the OutputDebugString() output is NOT being captured.

When I do the same with VS 2003, i.e attaching to the SAME dllhost process, it DOES capture the OutputDebugString output, and break points DO activate, but my symbolic info does NOT load (compiled with VS 2005).

FWIW, I can see 2 dllhost process, and I did try attaching to EACH seperatly as well as BOTH.

Finally, the script engine I try to debug is compiled with VS 2005 using full debug info, and oherwise functions perfectly.

What am I missing?

Ron Pinkas — Thu, 02 Feb 2006 07:21:26 GMT

Oops, sorry in VS 2003, with the project compiled with VS 2005, the break points do NOT activate, because teh symbolic info is not loaded, but the DEbugger DOES capture OutputDebugString(), and it DOES capture exceptions. It also DID activate break point when the project was compiled with VS 2003.

I also found I CAN tell my project to use "Web Service Debugger" and when I use url such as http://LocalHost/test.asp it DOES start IE, and it does capture an Error info posted by means of IActiveScriptSite::OnScriptError(), but break point which should have trigger BEFORE that point are NOT intercepted.

TIA,

Ron

Solution found.

As simple as it may sound, all I had to do was to select "Native code", in the "Attach to:" combo box, of the "Attach to Process" Dialog - the default "Automatic" simply fails to attach.

Hi Mikhail,

I have a question about ASP debugging. Have class library written in VB6 that is call from classic asp page. Can I debugg it all together with VS 2005 and VS 6 as I can debbug it with VS 2003 and VS 6.
I try debugging asp page with VS 2005 and it works but in that page I have calls of methods from some extern class written in VB6, that I need to debugg it also. I can not join this 2 debuggings.

Regards,
Igor

Hi Mikhail,

Thanks a lot for your posts. They have really helped me a lot already.

I have been trying to get Classic ASP debugging working with VS2005, in a mixed project of both .aspx and .asp files. The only difference is that I am using XP Pro with IIS 5.1

I followed your steps for enabling debugging. Instead of attaching to w3wp.exe, I am attaching to the inetinfo.exe process.
I can start without debugging, and then if I position my cursor inside the script or <% tags. I am able to set a breakpoint.
By then refreshing the .asp page using Ctrl-F5, my breakpoint is not hit, and the comment inside the Visual Studio IDE when I hover over the breakpoint symbol in the margin says: 'The breakpoint will not currently be hit, no symbols have been loaded for this document'

As a result, I was almost, but not quite able to show that debugging classic ASP pages is possible in IIS5.1 on XP

I am not able to spend any more time on this, so perhaps someone else can pick this up?

Best wishes
Graham.

Anyone know if you can debug classic ASP with Visual Web Developer Express? The Debug window does not have an option to attach to a process.

Mikhail Arkhipov (MSFT) — Mon, 24 Apr 2006 19:47:09 GMT

No, I don't think it is possible. VWD Express does not support attaching to processes.

Setting Debugging for Interdev ASP project in Windows 2003 Server / IIS6

// this step may not be needed.

Open Component Services->Component Services->Computers->MyComputer->DCom Config->Machine Debug Manager->Properties->Security.

For Launch and Activate and Access Permissions select Customize. Add Interactive and IWAM_COMPNAME.

In IIS6, create under your WebSites/Default Web Site your Application ABCApp, point to the folder where Interdev application and follow normal steps to create InterDev application(I did it in Master mode)

Set in IIS ABCApp/Properties/Configuration/Debugging. Set Debugging Flags for Enable ASP server-side and client-side debugging.

Go in IIS to Application Pools/DefaultAppPool->Properties->Identity. Set it to Configurable: IWAM_COMPNAME.

This let me stop at breakpoints in InterDev.
