Thread: a program that will call an execute but with arguments

is it possible in C++ that i have a program that will call on an executable of another program, but i would pass an argument to this executable from the calling program?

i'm using borland on winxp. the only see on calling an executable is ::shellexecute. but i don't think i could pass an argument from here.

thanks for the help..

::ShellExecute(..)

Code:

HINSTANCE ShellExecute(      
    HWND hwnd,
    LPCTSTR lpOperation,
    LPCTSTR lpFile,
    LPCTSTR lpParameters,
    LPCTSTR lpDirectory,
    INT nShowCmd
);

See the right parameter? Use the right parameter.

hmm...

i'm not sure if i am getting this correctly...

what if i am actually having arguments like a class? or i want to pass a class, could i use lpParameters?

the program that will be called will have this...

Code:

WINAPI WinMain(HINSTANCE hCurInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)

i can't see where lpParameters could have been passed?

sorry for such ignorance i am still on the process of learning this stuffs..

thanks!

The application you are starting up handles initializing itself and the WinMain entrypoint, and would usually call GetCommandLine(). All you have to do is pass the executables parameters as a C-string to ShellExecute(..).

Perhaps you could serialize it in human readable format.
