TProcess hide windows (Windows) lazarus / 34-Windows ---------------------------------------------------------------------- MickeSommar · 2012-12-12 06:27 Hi I'm trying to start a process (in windows), but do not want the window to appear. I have tried with the following code: Code: [Select]program RunCommandSilent; uses   process, sysutils; var   RunCommand: TProcess; begin   RunCommand:= TProcess.Create(Nil);   RunCommand.Executable:= 'calc.exe';   RunCommand.ShowWindow:= swoHIDE;   RunCommand.Execute; end. But the calc.exe will be displayed anyway. Have google the problem, tried different solutions, but no one will solve the problem. Anyone here who have any ideas? Best Regards Micke Sommar ---------------------------------------------------------------------- Leledumbo · 2012-12-12 06:52 Hint: See anything else you can use from TProcess.Options?
