ShellExecute
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.
renobj %1 %2
Is it the wrong way or wath ????

Or with '' instead of nil
ShellExecute(I, 'open', PChar('s:\public\homch2.ba
ShellExecute(I, 'open', PChar('s:\public\homch2.ba

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

If that doesnt work then try:
ShellExecute(I, 'Open', PChar('s:\public\homch2.ba
ShellExecute(I, 'Open', PChar('s:\public\homch2.ba

I try all of your examples and it was close "EPS" but one work right a way and earn the point.
ShellExecute(I, 'open', PChar('s:\public\homch2.ba
nil, sw_hide);
