Try using the ShellExecute API.

WinExec

The WinExec function runs the specified application.

Note This function is provided only for compatibility with 16-bit Windows. Applications should use the CreateProcess function.

<pre>

UINT WinExec(

  LPCSTR lpCmdLine,  // command line

  UINT uCmdShow      // window style

);

</pre>

Parameters

lpCmdLine

[in] Pointer to a null-terminated character string that contains 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. The GetSystemDirectory function retrieves the path of this directory.

4. The Windows directory. The GetWindowsDirectory function retrieves the path of this directory.

5. The directories listed in the PATH environment variable.

uCmdShow

[in] Specifies how a Windows-based application window is to be shown and is used to supply the wShowWindow member of the STARTUPINFO parameter to the CreateProcess function. For a list of the acceptable values, see the description of the nCmdShow parameter of the ShowWindow function. For a non-Windows ? based application, the PIF file, if any, for the application determines the window state.

Return Valuesb>

If the function succeeds, the return value is greater than 31.

If the function fails, the return value is one of the following error values:

Value Meaningb>

0 The system is out of memory or resources.

ERROR_BAD_FORMAT: The .exe file is invalid.

ERROR_FILE_NOT_FOUND: The specified file was not found.

ERROR_PATH_NOT_FOUND: The specified path was not found.

use an API and then use the keystring WinExec
