PRB: Developer Studio Hangs When Debug Breakpoint Is Set

RESOLUTION

The Express Meter software is available in both 16-bit and 32-bit versions. When you are running this software, the 16-bit version appears in the Task Manager as EM (for Em.exe) and the 32-bit version appears as EM32 (for Em32.exe). Express Meter software installs the Em.dll in the Windows ..\System or ..\System32 directory. The Visual C++ debugger installs this DLL in the C:\Program files\DevStudio\SharedIDE\BIN\ directory if you installed Visual C++ in the C: drive.

To resolve this problem, check the following registry key for Visual C++, version 5.0 :

   HKEY_CURRENT_USER\Software\Microsoft\DevStudio\5.0\Build System
    \Components\Platforms\Win32 (x86)\Execution Models
				

For Visual C++, version 6.0, check the following registry key:

   HKEY_CURRENT_USER\Software\Microsoft\DevStudio\6.0\Build System
    \Components\Platforms\Win32 (x86)\Execution Models
				

On the right panel you will see an entry "Current EM", and its value is set to "EM".

Change this value to the full path of the debugger's Em.dll for LoadLibrary to load the correct DLL.

The changed value will be similar to the following directory (depending on which drive Visual C++ is installed on).

For Visual C++, version 5.0:

   C:\Program files\DevStudio\SharedIDE\BIN\EM
				

For Visual C++, version 6.0:

   C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\EM
				

To change the value, double-click "Current EM", and type in the full path that appears above.

If this does not resolve the issue, end the task (EM or EM32) from the Task Manager. Note that if the System Administrator is running this task in a secured mode, you need appropriate permissions to end this task.
