autorun app

Hey all,

Hammer gave me this code to use in a small app that will be used in a cd autorun.inf file. I can get it to compile, but it errors out when I try to build it with this error:

LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main
Debug/AutoStart.exe : fatal error LNK1120: 1 unresolved externals

Code:

#define STRICT
#include <Windows.h>
/* */
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR pCmdLine, int nCmdShow)
{
int i;
for (i = 1; i < __argc; i ++)
{
if ((int) ShellExecute(NULL, NULL, __argv[i], NULL, NULL, SW_SHOWNORMAL) <= 32)
{// Error trying to run default browser, tell user
CHAR sz[1024];
wsprintf(sz, TEXT("Error openning %s on CD-ROM disc."), __argv[i]);
MessageBox(NULL, sz, TEXT("ShellExecute"), MB_OK | MB_ICONWARNING);
}
}
return(0);
}

help?

I'm new to c++, but I'm wondering... do I need a Main to call that API??

This belongs in the Windows development forum.

Your compiler expects main() to be the program's entry point, not WinMain().

Just change it to

Code:

int main(int argc,char *argv[])

Be sure to changes references to "__argc" and "__argv" to "argc" and "argv".

If you do that it will become a console app, which is a bit yak for what you want.

Better just compile it as a windows app in the first place. What compiler are you using?

sweet... thanks. Sorry about posting in the wrong forum.. I wasn't sure where to put it.

MSVC 6

I didn't know you had to compile it differently.

They'll be an option in the compile settings to create a console or a GUI app. You need GUI.

I can't guide you any further with MSVC6, I'm one of the few people in the world that doesn't have it But I'm sure someone else will step in and advise.

I found it.....(finally)

You probably won't have to create a new project. Just go to Project->Settings->Link->(Category)General, down in the Project Options edit box, you should see "/subsystem:console". Change "console" to "windows".

I did that to my console app and got:

LIBCD.lib(wincrt0.obj) : error LNK2001: unresolved external symbol _WinMain@16

go to new---win32 application (should be right above win32 console application) ---select standard (second option) and put the code into that project.
