[Wrapper-user] [ 851223 ] Run the Wrapper on Windows without a console

[Jim R. <jr...@er...>]

Does anyone care about this?  (With apologies to the "the wrapper should 
only be used for services" folks.)

With the idea of making a wrapperW.exe, the solution seems to go about 
like this (some refinements and more testing needed).  Modify
wrapper_win.c

replace:

void _CRTAPI1 main(int argc, char **argv) {

with something like this, then compile it as a Win32 application:

void _CRTAPI1 myMain(int argc, char **argv);

#ifdef _WIN32

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR 
lpCmdLine, int nShowCmd ) {
          char** argv = malloc(sizeof(char *)*1);
     MSG msg;
     BOOL bRet;

         char appName[MAX_PATH];

    GetModuleFileName(hInstance, appName, sizeof(appName)-1);
          argv[0] = appName;

    myMain (1, argv);

     // Start the message loop.

     while( (bRet = GetMessage( &msg, NULL, 0, 0 )) != 0)
     {
         if (bRet == -1)
         {
             // handle the error and possibly exit
         }
         else
         {
             TranslateMessage(&msg);
             DispatchMessage(&msg);
         }
     }

}

#else {

void _CRTAPI1 main(int argc, char **argv) {
   main(argc, argv);
         }

#endif

// renamed main.
void _CRTAPI1 myMain(int argc, char **argv) {
[...]


The problem is that I don't parse the arguments - just push in argv[0]. 
  The lpCmdLine string seems to be pretty close, but I think that it's 
missing argv[0] - the application name.

There are a number of examples of parsing and creating an argv and argc. 
For example, this message seems to contain the code:

http://public.kitware.com/pipermail/cmake/2004-June/005170.html

This seems close:

http://wwwhome.cs.utwente.nl/~gansevle/win32/wstart/wstart.c

But the most thorough work I've found is here

http://cvs.sourceforge.net/viewcvs.py/fellow/fellow/SRC/WIN32/C/WINMAIN.C?view=markup

from the "fellow" project:
http://sourceforge.net/projects/fellow

This code is GPL'd and so incompatible with the Wrapper license.  I 
expect that if we asked, they'd allow the wrapper to use that piece of 
code (bottom 1/3 of the file or so), but someone would have to be 
intereted enough to ask.
