hi,

i thought this might be a easy task but i am not able to manage it.

task:
- read an integer value from edit1.text
- start a program.exe (via cmd)
- add +5 to the integer value and send this value to the opened program

what would be the easiest way to do this??

The easiest would be to pass the value as a command line parameter. If you need to communicate with the program, you need to know what messaging systems it supports (if it isn't yours) or that you want to implement (if it is).

It's not so easy. In Delphi you can use:
MaxX's delphi site - TDosCommand
to execute some command

DosCommand1.CommandLine:='ping google.coml';

DosCommand1.Execute;

to receive you must assign and action to event onNewline. For example:

procedure TForm1.DosCommand1cNewLine(Sender: TObject; NewLine: String;

  OutputType: TOutputType);

var

  num,newnum: Integer;

begin

  num:=StrToInt(NewLine);

  // process somehow this variable

  newnum:=num+5;

  dosc.SendLine(IntToStr(newnum),true);

end;

not compiled but should work ok
