Dont remember the exact error message. Regsvr32 doesnt provide a way to check if a dll is registered or not. Hope this helps. Is there a specific solution for this? I am able to access the dll properties when i load the dll into a TypeLib which will give me its major, minor, guid etx But i cant tell if its registered or not.
I am confused. Is there a way out? You can unregister multiple dll files simply by selecting them in the upper pane, and then using the "Unregister Selected Files" option. If you don't specify this option, the list is sorted according to the last sort that you made from the user interface.
Examples: RegDllView. Open the created language file in Notepad or in any other text editor. Translate all string entries to the desired language. After you finish the translation, Run RegDllView, and all translated strings will be loaded from the language file. If you want to run RegDllView without the translation, simply rename the language file, or move it to another folder.

CallWindowProc expects a window handle and four parameters, not a pointer to a function. This code should never have worked on any version of Windows, and I'd suspect it actually never has; that you're seeing the DLL registered on any system is probably the result of something else registering it.
Using CallWindowProc was a common horrible hack used to invoke a function pointer as its implementation will arbitrarily run whatever its passed. Unfortunately I am being told to do it this way because "there are sometimes issues with calling DllRegisterServer directly".
That was what I was doing originally but I was told I couldn't do it that way. In any case though even when using DllRegisterServer directly I still receive the same error. Any other ideas? I have discovered that the issue is with the CreateObject call. However on XP it just creates a generic Object. Does anyone know why this occurs? Can CreateObject not be used for specific types on XP?
You don't actually need to know the GUID beforehand. Massimo: but how I would search for it? In which key? It can wrongly display in the shell history e. User-specific things like shell history are under HKCU. Massimo: if you put an answer here with the shell command to search for it, I'll mark it as the correct answer. Show 1 more comment.
Find registry entries that contain the DLL name. These entries typically use GUIDs as their keys. Orafu Orafu 31 1 1 bronze badge. Sign up or log in Sign up using Google.
