I try to execute a command in shell via delphi but it won't work. I use this script:

var
shellexecommand:string;
begin
ShellExecute(0, nil, 'cmd.exe', '/C ' + shellexecommand + ' > output.txt', nil, SW_HIDE);
end;

But i get the error:

[dcc32 Error] Unit1.pas(329): E2010 Incompatible types: 'PWideChar' and 'AnsiString'

Also if i change string to pwidechar is doesn't work. How can i fix this?

You might be better with CreateProcess here. Particularly if you actually want the output of the other process in the parent and don't need the text file to endure. – David Heffernan

Try this:

var
  shellexecommand:string;
begin
  // shellexecommand := ....
  shellexecommand := '/C ' + shellexecommand + ' > output.txt';
  ShellExecute(0, nil, 'cmd.exe', PChar(shellexecommand), nil, SW_HIDE);
end;
