Calling a Dll function !

hi,



I try to call a C++ Dll. When i do it in a Standard Exe , it works fine . ( only after compile and run the .exe, because in debug mode the Dll returns me nulls pointer i think )



i try to call the dll functions via an ActiveX and it breaks on " Error Method '~" of object '~' failed " ( always with the .exe )



????



but i would want to access this Dll via a WebClass.



So i try into it , but it breaks on Bad DLL Calling convention ,or Type mistmatch , but the code is exactly the same as in the Standardt Exe.



So if someone know why i couldnt test this dll calls in debug mode and why with the standard exe it works and not with the webclass.




Help will be appreciate , Thks
