WinExec(

    LPCSTR lpCmdLine,     // address of command line
    UINT uCmdShow      // window style for new application
   );    
 

Parameters

lpCmdLine

Points to a null-terminated character string that contains the command line (filename 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, Windows 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

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 Values

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:


winexec('c:\command.com /c dir',SW_SHOWNORMAL     )


i hope this work
