I'm trying to load a DLL on Windows platform and I get the following error:

>> loadlibrary('LADY_1_25_000', hfile);
??? Error using ==> loadlibrary at 474
There was an error loading the library "LADY_1_25_000"
Die angegebene Prozedur wurde nicht gefunden.



Caused by:
    Error using ==> loaddefinedlibrary
    Die angegebene Prozedur wurde nicht gefunden.


The library is in Windows searchpath and is found ! It is linked dynamically against MFC-Dlls and Qt-Dlls !  I wrote a simple MFC-program and tried to load the same library via C-Windows function LoadLibrary  and it worked ! Are there restrictions for loading dll with Matlab ??
