    executing program....

    hi,
    2. I have problem when executing program from windows, I use: system("c:\\windows\\Notepad.exe"); and all is ok but that stupid dos box appears when notepad is executed, now the question, how to execute program without dos box???

    2. I used ShellExecute but got an error while compiling:
    "passing `const char *' as argument 1 of `ShellExecuteA(HWND__ *, const CHAR *, const CHAR *, const CHAR *, const CHAR *, int)'" so whats the syntax of ShellExecute ??

    ShellExecute(HWND_DESKTOP,"open","c:\\windows\\Not epad.exe",NULL,NULL,SW_SHOWNORMAL);

    You can also use WinExec("notepad.exe", SW_SHOWNORMAL);
    or WinExec("notepad.exe path_file.txt", SW_SHOWNORMAL);

    WinExec( ) is for 16-bit compatibility though... You should really start using CreateProcess for the newer Windows OS's...

    Code:
    BOOL CreateProcess(
      LPCTSTR lpApplicationName,                 // name of executable module
      LPTSTR lpCommandLine,                      // command line string
      LPSECURITY_ATTRIBUTES lpProcessAttributes, // SD
      LPSECURITY_ATTRIBUTES lpThreadAttributes,  // SD
      BOOL bInheritHandles,                      // handle inheritance option
      DWORD dwCreationFlags,                     // creation flags
      LPVOID lpEnvironment,                      // new environment block
      LPCTSTR lpCurrentDirectory,                // current directory name
      LPSTARTUPINFO lpStartupInfo,               // startup information
      LPPROCESS_INFORMATION lpProcessInformation // process information
    );
    Imported from Kernel32 (so you dont need any more libs that a standard project) and defined under windows.h

    Its a complex and very powerful func....

    For Shell Execution I prefer...er...ShellExecute() as it can run documents and launch a program based on extension settings
