When using the TProcess to run an application under your compiled
program, I need to issue a virtual keystroke combination.

How do you enter a key combination for the command line that requires
shift and ctrl keys, example: shift+ctrl+Q

AProcess.CommandLine := [VK_SHIFT]+[VK_CTRL]+'Q';  does not work
AProcess.Execute;

Thanks for your assistance.

Use AProcess.Input.Write() method. I don't really know how a key
combination is handled, but I guess it's worth to try:
Code: [Select]var
  s: String;
begin
  s:=Chr(VK_SHIFT)+Chr(VK_CTRL)+'Q';
  AProcess.Input.Write(s[1],Length(s));
end;
Call it after execute. Precisely, after the program blocks for input.
