Easy Quick question on running things

How do you run a program from C++? I know how to do it in VB, but I don't know what to use to do it in C++, anything similar to Shell="c:\~~~~\*.exe", vbnormalfocus and such?

Use the ShellExecute API. You also need to include windows.h header.

Code:

---

HWND hWnd = FindWindow (NULL,"appname"); //if you don't know the HWND
ShellExecute(hWnd,"open"  ,"c:\\windows\\notepad.exe",NULL,NULL,SW_SHOW );

---

I think the WinExec api is easier to understand for this task.

It's in kernel32 and think it's available in C++.

Here's an example.

Code:

---

WinExec("my.exe", 1);
// also accepts parameters like my.exe -a -x -s http://vbworld.com

Ps: Vlatko, I don't think the ShellExecute really needs the hWnd parameter, I used it in VB just by passing 0&, should work too (I'm at my work now so I can't test)

The hWnd parameter has its own value here. Receiving errors in a form of a message box.

MSDN:

Code:

---

hwnd
Window handle to a parent window. This window receives any message boxes that an application produces. For example, an application may report an error by producing a message box.
