How to call _wsystem without showing console?

Question

I would like to copy a file to a destination by using batch command in my code.

    szCommand.Format(_T("copy \"%s\" \"%s\""), szOrg, szTargetFile);
    _wsystem(szCommand);

However, each time _wsystem is called, a console window will be prompted, which is very unpleasant.

Is there a way to call _wsystem without showing out the console window? Or any other alternative?

Ditch the console app and do this from a GUI app. Also see: http://flipcode.com/archives/Win32_ConsoleWindowed_Tip.shtml — Cody Gray - on strike, Jan 12 '11 at 06:37
Thanks to all answers. I finally chose CopyFile WIN32 function. — wengseng, Feb 24 '11 at 06:11

To exert control over how a new program appears, use CreateProcess. Then you can use the CREATE_NO_WINDOW process-creation flag to hide the window of a console program.

But to copy a file from one place to another, skip the external programs and just call CopyFile.

Or [`SHFileOperation`](http://msdn.microsoft.com/en-us/library/bb762164.aspx) with `FO_COPY`, if a nice graphical progress display is desired. – ephemient Jan 12 '11 at 06:57

Why shell-out when there's a Win32 API that will copy a file for you. It's called CopyFile!

Details here: http://msdn.microsoft.com/en-us/library/aa363851%28VS.85%29.aspx

#include <windows.h>

CopyFileA(szOrg, szTargetFile, FALSE);  // use CopyFileW if szOrg and szTargetFile are unicode strings

Would having the window minimized be okay? See this.
