WinExec Function
Runs the specified application.
Note: This function is provided only for compatibility with 16-bit Windows. Applications should use the CreateProcess function. Syntax UINT WINAPI WinExec(
__in LPCSTR lpCmdLine,
__in UINT uCmdShow
Parameters lpCmdLine [in] The command line (file name plus optional parameters) for the application to be executed. If the name of the executable file in the lpCmdLine parameter does not contain a directory path, the system searches for the executable file in this sequence:
1. The directory from which the application loaded.
2. The current directory.
3. The Windows system directory (GetSystemDirectory).
4. The Windows directory (GetWindowsDirectory).
5. The directories listed in the PATH environment variable.
uCmdShow [in] Specifies how the window is to be shown. This parameter is ignored the first time an application calls ShowWindow, if the program that launched the application provides a STARTUPINFO structure. Otherwise, the first time ShowWindow is called, the value should be the value obtained by the WinMain function in its nCmdShow parameter. In subsequent calls, this parameter can be one of the following values.
Windows 2000/XP: Minimizes a window, even if the thread that owns the window is not responding. This flag should only be used when minimizing windows from a different thread.
Hides the window and activates another window.
Maximizes the specified window.
Minimizes the specified window and activates the next top-level window in the Z order.
Activates and displays the window. If the window is minimized or maximized, the system restores it to its original size and position. An application should specify this flag when restoring a minimized window.
Activates the window and displays it in its current size and position. SW_SHOWDEFAULT
Sets the show state based on the SW_ value specified in the STARTUPINFO structure passed to the CreateProcess function by the program that started the application. SW_SHOWMAXIMIZED
Activates the window and displays it as a maximized window.
Activates the window and displays it as a minimized window.
Displays the window as a minimized window. This value is similar to SW_SHOWMINIMIZED, except the window is not activated.
Displays the window in its current size and position. This value is similar to SW_SHOW, except the window is not activated.
