Hello,
I'm trying to compile this simple Hello World script using Visual Studio 2005 and can't even make it work. Here is my script:
#include <windows.h>
int
CALLBACK WinMain(HINSTANCE hInstance,
HINSTANCE hInstNULL,
LPSTR lpszCmdLine,
int nCmdShow){
MessageBox(NULL,
"Hello World","Tutorial Example 1",MB_OK|MB_ICONINFORMATION);return(0);
}
I get the following errors:
error LNK2028: unresolved token (0A000021) "extern "C" int __stdcall MessageBoxA(struct HWND__ *,char const *,char const *,unsigned int)" ( MessageBoxA@@$$J216YGHPAUHWND__@@PBD1I@Z) referenced in function "extern "C" int __cdecl MessageBox(struct HWND__ *,char const *,char const *,unsigned int)" ( MessageBox@@$$J0YAHPAUHWND__@@PBD1I@Z)
1>PROG3_2.obj : error LNK2019: unresolved external symbol "extern "C" int __stdcall MessageBoxA(struct HWND__ *,char const *,char const *,unsigned int)" ( MessageBoxA@@$$J216YGHPAUHWND__@@PBD1I@Z) referenced in function "extern "C" int __cdecl MessageBox(struct HWND__ *,char const *,char const *,unsigned int)" ( MessageBox@@$$J0YAHPAUHWND__@@PBD1I@Z)
What option do I have to toggle or what part of my coding should I modify I am totally new to programming and would like to know more about it. Thanks!!
Can't compile this little program!!!

you're not linking your program with the user32.lib (that's where the MessageBox is). Go to your project properties->Linker->Input->Additional Dependencies and add: user32.lib
