when I leave QuarkInit (char * connect) it compiles but generates an error in the main
main.o : error LNK2001: símbolos externos indefinidos "void __cdecl QuarkInit(wchar_t *)" (?QuarkInit@@YAXPA_W@Z) I let in QuarkInit ( TCHAR * connect) the main error does not appear but aparace of that part of code
is to correct these mistakes without exchange TCHAR to char if someone is enteressa one can up the required code

excuse my English

- avoid mixing languages: use Google Translate to help you to write English only.
- Tell us where are the errors.
- avoid Email address in message.

your problem is that you are compiling for UNICODE. It means that a character has two bytes. It is a weired theme but if you want to code you got to learn it someday. Here is some tutorial.

For Unicode you must use similar named C-functions with the UNICODE signature. For instance wcscmp for strcmp. On the Microsoft site are they fine documented.

The quick and dirty solution is to change the implementation signature to:

C++

QuarkInit (char * connect)

Be aware of type cast warning - they are your friend.

Please stop reposting this same query. A number of people have explained what the issue is and how to fix it. And I have also given you a link to an article that gives the technical details of how to use either ASCII or Unicode in your programs.
