I have made a dll's which runs perfectly under windows95 however under windows nt I got the message dll not found.

Tried regsvr32 dllname.dll with as result the following message :

Dllregisterserver entry point was not found. DllRegisterServer may not be exported, or a corrupt version of dllname.dll may be in memory

I am not understanding this why because of the fact that the dll is not an OLE server neither of these things the only wicked thing is that it works under windows95.

Help me out dudes.

regards,

Cono

Hi Cono,

I can't explain why it works with win95 and NOT with NT. Perhaps you should just try to add this to your dll (if you don't have done this already):

uses comServ;

exports DllGetClassObject, DllCanUnloadNow, DllRegisterServer, DllUnregisterServer;

Regards, Madshi.

I think you need D3 or D4 to compile it...

If it is not a ole server, then there is no point calling regsvr32. All it does is load the dll, locate and find that function, call it, then close the library.

Cono, I know you're not a bozo so forgive me if I offend you with such obvious comments like these:
Is the dll in \system or \system32?
Is it on the path?
Try putting it in the exe dir.

Also, when you declare the function in your exe, type external 'dllname.dll' at the end, not just external 'dllname';
I was bitten by this once, but it was a D1 program on NT.

Cheers,
Phil.

Umm.. On reflection I think the answer is none of the above.

Do you declare youre functions like this (in an interface unit)?:

procedure MyFunc; external 'MyDLL';

if so change them so they look like this:

procedure MyFunc; external 'MyDLL.DLL';

NT is touchy about missing extensions on DLL filenames...

Let me know how you go.

Cheers,

Raymond.

IT, Stop Being Called Into Every Meeting

Highfive is so simple that setting up every meeting room takes just minutes and every employee will be able to start or join a call from any room with ease. Never be called into a meeting just to get it started again. This is how video conferencing should work!

Madshi,

Yes your comment solved my problem

However it is kind of strange that the same dll works on windows 95 but not on windows NT without registering the dll with regsvr32. Don't you agree with me

Anyhow thanks,

regards,

Cono
