Title: MinimizeAll Shell Command
Question: I was asked how to implement the MinimizeAll feature of the new
Win2K shell.
Answer:
I found that if you import the Microsoft Shell Controls & Automation Type Library, you have this functionality in a component.
Select Project..Import Type Library... from the menu
Select Microsoft Shell Controls & Automation (version 1.0).
Click Install...
There will be several components placed on the ActiveX palette tab. Drop a TShell Component on your form or DM and you canMinimize all just by doing this:
Shell1.MinimizeAll;
/*********************************************************************
There are many really cool shell tricks available when you use the TShell
Control.

procedure TForm1.Shell(sMethod: Integer);
begin
case sMethod of
0:
//Minimizes all windows on the desktop
begin
Shell1.MinimizeAll;
Button1.Tag := Button1.Tag + 1;
end;
1:
//Displays the Run dialog
begin
Shell1.FileRun;
Button1.Tag := Button1.Tag + 1;
end;
2:
//Displays the Shut Down Windows dialog
begin
Shell1.ShutdownWindows;
Button1.Tag := Button1.Tag + 1;
end;
3:
//Displays the Find dialog
begin
Shell1.FindFiles;
Button1.Tag := Button1.Tag + 1;
end;
4:
//Displays the Date/Time dialog
begin
Shell1.SetTime;
Button1.Tag := Button1.Tag + 1;
end;
5:
//Displays the Internet Properties dialog
begin
Shell1.ControlPanelItem('INETCPL.cpl');
Button1.Tag := Button1.Tag + 1;
end;
6:
//Enables user to select folder from Program Files
begin
Shell1.BrowseForFolder(0, 'My Programs', 0, 'C:\Program Files');
Button1.Tag := Button1.Tag + 1;
end;
7:
//Displays the Taskbar Properties dialog
begin
Shell1.TrayProperties;
Button1.Tag := Button1.Tag + 1;
end;
8:
//Un-Minimizes all windows on the desktop
begin
Shell1.UndoMinimizeAll;
Button1.Tag := 0;
end;
end; {case}
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
Shell(Button1.Tag);
end;
