Title: How to show the windows display properties tab?
Question: The use of 'Rundll32.exe' in windows is very easy using the 'shellexecute' command in Delphi. Make sure 'shellapi' is in your uses list.
Answer:
function GetSystemDir: TFileName;
var
SysDir: array [0..MAX_PATH-1] of char;
begin
SetString(Result, SysDir, GetSystemDirectory(SysDir, MAX_PATH));
if Result = '' then
raise Exception.Create(SysErrorMessage(GetLastError));
end;
procedure TForm1.Button1Click(Sender: TObject);
var
x:Tfilename;
begin
x := getsystemdir;
ShellExecute(Form11.Handle, 'open' , Pchar('rundll32.exe') , 'shell32.dll,Control_RunDLL Desk.cpl,@0,3', Pchar(X), SW_normal);
end;
//getsystemdir is a function that is compatible for all windows versions.
