I'm trying to link into a dll explicitly or dynamically and my code could not find the dll. This code is taken from wikipedia for testing. Could anyone tell me what am I doing wrong? I'm using VSC++ 2005.





I appriciate the help

Oh, by the way, some of you may think that it should be HINSTANCE instead of HMODULE; But HMODULE is also type defined as HINSTANCE under winbase.h

I see a mixture of ASCII and UNICODE there - is the cast to LPCWSTR really necessary in your LoadLibrary call?

I have it without the LPCWSTR before and when I try to compile, VC++2005 compiler is has an error saying that it cannot conver from char to LPCWSTR... is there an option that you can think of that deals with that?

No, no options - simply that your code is wrong. Instead of casting an ASCII string to UNICODE, which just tells the compiler to treat the ASCII string as if it were UNICODE, you need to actually provide a UNICODE string.

I also found a solution, by including #include<tchar.h> and putting it this way:




then it works. Thanks.

IIRC, if you include <atlconv.h> as well, you can use all of the ATL string conversion functions which are pretty much portable.

This may also help as well:

@frstPrsn, same difference. The _T macro, as well as _TEXT and TEXT effectively transform the text inside the brackets into what I posted, depending on whether the _UNICODE macro is defined or not.
