Veena here to discuss an issue that might affect developers using Visual Studio 2005 to perform client side script debugging.
After you install Internet Explorer 8, you may no longer be able to perform client side script debugging using Visual Studio 2005. This issue is discussed in http://blogs.msdn.com/greggm/archive/2009/04/01/script-debugging-broken-in-vs-2005-after-installing-ie8.aspx.
Typically, setting the registry value : TabProcGrowth to a DWORD value of 0 is sufficient to resolve this problem. However, if you are using Windows Vista, you need to follow ALL of the steps below to resolve this issue:
1) Install VS 2005 update for Vista from http://www.microsoft.com/downloads/details.aspx?FamilyID=90e2942d-3ad1-4873-a2ee-4acc0aace5b6&displaylang=en.
2) Install Visual Web Developer express from http://www.microsoft.com/express/vwd/Default.aspx. This is to update PDM.DLL to the required version.
Please note: You don’t need to actually use it and can remove it after it is installed. Visual Web Developer express is the free Express SKU for VS2008.
3) Set the registry value : TabProcGrowth to a DWORD value of 0 under HKCU\Software\Microsoft\Internet Explorer\Main.
4) Run Visual Studio 2005 with elevated permissions.
Please note: This is a problem in Visual Studio 2005 and doesn’t happen with Visual Studio 2008.
