Usage
In the form's OnShow (or maybe OnCreate) create the object like this:
uses
win32taskbarprogress;
procedure TForm1.FormShow(Sender: TObject);
begin
GlobalTaskbarProgress:= TWin7TaskProgressBar.Create;
end;
And then call properties of this object like this:
//to change state: none, green, yellow, red, floating
GlobalTaskbarProgress.Style:= TTaskBarProgressStyle(ComboBoxStyle.ItemIndex);
//to change progress value 0 to 100
GlobalTaskbarProgress.Progress:= Edit1.Value;
Author tried to initialise the object in the "initialization" part of win32taskbarprogress, but failed, maybe because the Application.Handle is not initialised so early.
