    Run A Program from within a cpp code

    I want to execute a program (say test.exe). But I want to do it from inside a C++ file as I want to have a delay after the program executes, how can I execute a program on disk from inside cpp? it's on my comp, so it doesn't matter about security if i have to turn off some stuff...

    tried
    Code:
     #include <windows.h>
    #include <shellapi.h>
     
    void main() {
    char* URL = "C:\\test.exe>";
     
    ShellExecute(NULL, "open", URL, NULL, NULL, SW_SHOWNORMAL);
    }
    but got errors:


    t1.obj : error LNK2028: unresolved token (0A000017) "struct HINSTANCE__ * __stdcall ShellExecuteA(struct HWND__ *,char const *,char const *,char const *,char const *,int)" (?ShellExecuteA@@$$J224YGPAUHINSTANCE__@@PAUHWND__ @@PBD111H@Z) referenced in function "int __cdecl main(void)" (?main@@$$HYAHXZ)

    t1.obj : error LNK2019: unresolved external symbol "struct HINSTANCE__ * __stdcall ShellExecuteA(struct HWND__ *,char const *,char const *,char const *,char const *,int)" (?ShellExecuteA@@$$J224YGPAUHINSTANCE__@@PAUHWND__ @@PBD111H@Z) referenced in function "int __cdecl main(void)" (?main@@$$HYAHXZ)

    You can fire off another process or use a thread. Why are you wanting to do this?

    well I don't know what you mean by that...

    I want to be able to show some stuff on the screen (well the console screen anyway), and then make the program load.

    It performs well when I test it on my machine.

    Try linking to `shell32.lib'.

    In the project settings, the linker option, input tab, there's an "additional libraries" field. Just put the library name in there.
    All the buzzt!
