Question:
How do I launch a control panel applet?
Answer:
You can launch a control panel applet by calling WinExec
to execute control.exe, passing the name of the control
panel applet as a command line parameter. Applets files
(.cpl) can be found in the Windows system directory. Note:
Some of the applet files will not be found in the Windows
system directory. Those applets can be executed simply
by name.
Example:
procedure TForm1.Button1Click(Sender: TObject);
begin
WinExec('C:\WINDOWS\CONTROL.EXE TIMEDATE.CPL',
sw_ShowNormal);
WinExec('C:\WINDOWS\CONTROL.EXE MOUSE',
sw_ShowNormal);
WinExec('C:\WINDOWS\CONTROL.EXE PRINTERS',
sw_ShowNormal);
end;
