What are the Standard Header Files?

I want to write a small proggie in C++ 5 (or 6). It should not have an interface, and it should not have MFC support or database support. All it has is the main function:

void main () {
// trivial code here
}

My program NEEDS to include a minimum of headers and stuff -- smaller is better!!!!!!!!! BUT, I need to perform a ShellExecute call in main, so what is the minimum number of header files I need for this?

I tried including <windows.h>, but I get an unresolved external ref or whatever. The problem is something to do with "Win16main" or something like that.

I am sure the answer is simple, but what am I doing wrong????

You either can create a console application and write a main function, or create a GUI function and write a WinMain function. If you don't want anything to appear you write a GUI app, a WinMain, include <windows.h> but don't create a window, just use the ShellExecute.

Actually, you don't need any include at all:

Code:

---

extern "C" void* ShellExecuteA(void*, const char* szOp, const char*szFile, const char* szParams, const char* szDirectory, int iShowCmd);

int WinMain(void* hInst, void*, char* szParams, int iShowCmd)
{
  int iErr = (int)ShellExecuteA(  // the HINSTANCE return is for compatibility only
    0, 0, // no parent and no op (= open)
    "drive:\\path1\\path2\\filename.ext",  // the file to open
    szParams, // just pass our own params
    "drive:\\path1\\path2", // default path is execution directory
    iShowCmd);  // show the same way this was intended to be shown
}

---

And you only need one import libraray, I think it's SHLWAPI.LIB.
Then you have a valid app.



Of course this is not recommended.

Ah, OK. That makes sense.... I am sure I can figure out the rest.

Thanks a lot.
