Asp – Classis ASP debugging global.asa in VS2005

In order for Javascript debugging to work the Visual Studio needs to be attached as a debugger to the IE process and it needs to be able to resolve the phyiscal path of the javascript file with the URL of the same script loaded in IE.

Have you checked that when you start debugging in VS that it actually attaches to the IE process that gets spun up?

Customizer your toolbar, on the commands tab select the debug category then find the "Script Explorer" command, drag it to a tool bar. Close the dialog.

Using script explorer you should be able to find the script that ought to have the break point on. Ordinarily VS is able to combine the root path it specifies for the developer web server with the physical JS file path in order to determine what its URL would look like from the browsers perspective, it can then novate the break point from the physical file to the script loaded in the browser.

You can make a macro in VS2005 to do this.

Contains an example of attaching to the Calc process.

Sub AttachToCalc()
       Try

              Dim dbg2 As EnvDTE80.Debugger2 = DTE.Debugger
              Dim trans As EnvDTE80.Transport = dbg2.Transports.Item("Default")
              Dim dbgeng(1) As EnvDTE80.Engine

              dbgeng(0) = trans.Engines.Item("Native")

              Dim proc2 As EnvDTE80.Process2 = dbg2.GetProcesses(trans, "JIMSMACHINE").Item("calc.exe")

              proc2.Attach2(dbgeng)

       Catch ex As System.Exception
              MsgBox(ex.Message)
       End Try

End Sub
