Ok so im trying to create an console program that opens a website, but i get an error saying:
"Run-Time Check Failure #3 - The variable 'Handle' is being used without being initialized."

And heres the code of the program:

#include "stdafx.h"
#include <iostream>
#include <windows.h>

int main()
{
HWND Handle;
ShellExecute(Handle,
"open",
"http://www.youtube.com/",
NULL,NULL,SW_SHOWDEFAULT);
return 0;
}

Thanks if someone can help me! :D

What is the problem? You can not understand the phrase "The variable 'Handle' is being used without being initialized."?! If so you shall not do programming.

Well when i debug it. I need to click ignore to run it. But when i open the .exe file from my debug folder. I cant run it cos of the error.

You use variable Handle as an argument in the function call

ShellExecute(Handle,
"open",
"http://www.youtube.com/",
NULL,NULL,SW_SHOWDEFAULT);

but the variable has undefined value because it was not initialized.

thanks for trying to help but my problem is i have no idea what "argument" and "initialized" means in c++..

Maybe you need to learn the basics of C++ before trying to use the Windows API?

Edit: And argument is a command passed to a function, in your case, the function would be ShellExecute() and Handle, "open", "http://www.youtube.com/", NULL, NULL, SW_SHOWDEFAULT" are all arguments

Initializing a variable is assigning a value to that variable. You "declared" HWND Handle but never gave it a value.

Oh, now i get it wheres the problem :)

{
HWND Handle;
Handle = NULL;
ShellExecute(Handle,
"open",
"http://www.youtube.com/",
NULL,NULL,SW_SHOWDEFAULT);
return 0;
}

Thanks for the help guys! :)

@yge3d
thanks for trying to help but my problem is i have no idea what "argument" and "initialized" means in c++..

If you have no idea what argument and initialization mean then why do you deal with this code?!

HWND is a data type that holds a "handle" to a window.

This value is usually given when you call a create window function.
