exporting functions from debugged dll

[padawan]

Hi everyone,

I have a problem with a dll file. I have a 32 bit dll file and a program (x86 debugged) which uses the functions exported from the dynamic link library file and working well. I changed my program codes to 64 bit along time ago without an error and without changing the codes of calling functions. I also found the source code of the dll file and debugged the 64 bit dll file (x64 debug) without any error or warning. But when I call a function from the dll file, it does nothing. No error or warning messages instead! The declaration of the functions in the dll file are listed below:

When I debug the program, there are only ignorable warning messages like:
Possible problem detected while building assembly 'Kalibrasyon': Referenced assembly 'mscorlib.dll' targets a different processor
Possible problem detected while building assembly 'Kalibrasyon': Referenced assembly 'System.Data.dll' targets a different processor

Is this the reason? Codes ran well on x86 debug. Where is the problem? Any idea will be appreciable.

Thanks
