Need help with this.

I use ShellExecute to start a .bat file and want to pass variable to it.
Variables is given from dos when I start the program.
It look like this.
ShellExecute(I, 'open', 'c:\command.com', PChar('/c  s:\public\homch2.bat '+ ParamStr(1) + ParamStr(2)), nil,  sw_hide);

In the bat file it look like this.

ShellExecute(I, 'open', PChar('s:\public\homch2.bat '+ ParamStr(1) + ParamStr(2)), , '' , '', sw_hide);

I found this, how do I use the lpParameters in my example.


HINSTANCE ShellExecute(

    HWND hwnd,     // handle to parent window
    LPCTSTR lpOperation,     // pointer to string that specifies operation to perform
    LPCTSTR lpFile,     // pointer to filename or folder name string
    LPCTSTR lpParameters,     // pointer to string that specifies executable-file parameters
    LPCTSTR lpDirectory,     // pointer to string that specifies default directory
    INT nShowCmd      // whether file is shown when opened
   );

lpFile

Pointer to a null-terminated string that specifies the file to open or print or the folder to open or explore. The function can open an executable file or a document file. The function can print a document file.

lpParameters

If lpFile specifies an executable file, lpParameters is a pointer to a null-terminated string that specifies parameters to be passed to the application.
If lpFile specifies a document file, lpParameters should be NULL.

Hi meikl   (o:

Dark King, also make sure that you use double quotes ("), when command and/or parameters contain spaces.

ShellExecute(I, 'open', PChar('"s:\public\homch2.bat" "'+ ParamStr(1)+'" "'+ParamStr(2))+'"', '' , '', sw_hide);

In most cases I leave lpParameters and lpDirectory empty (='').

Try this:

ShellExecute(I, 'Open', PChar('s:\public\homch2.bat'), PChar(ParamStr(1) + ' ' + ParamStr(2)), '', SW_HIDE);

I havent tested it but it should work.

If that doesnt work then try:

ShellExecute(I, 'Open', PChar('s:\public\homch2.bat'), PChar(ParamStr(1) + ParamStr(2)), '', SW_HIDE);
