May be written in vc company source (ago) now want to use c builder to open the project-CodePudding

Novice and guidance!
And how c + + builder call vc write DLL!
Thank you very much!!!!!!

CodePudding user response:

What is the engineering file extensions?

CodePudding user response:

Not sure what you mean to say clearly

CodePudding user response:

BCB a transformation function of vc projects, but have never used, don't know what to use is not working, if just call DLL, there are two methods:
1) check vc provided lib and header files, if any, can be directly added to the project of BCB, may require the COFF to the transformation of the OMF, many articles under the search
2) if there is no.lib file, but there is a header file or know the DLL function parameters, also can use dynamic loading,
LoadLibrary cooperate GetProcAddress call

CodePudding user response:

@ 9527
I feel you say the second should be a good boss also let me use the loadlibarary he said just now let me write a small program and then use his header files and. DLL dynamic library to raise an example again? Thank you!
