**************************************************************************************
* Unit MSProdKey v2.2 *
* *
* Description: Decode and View the Product Key, Product ID and Product Name used to *
* install: Windows 2000, XP, Server 2003, Office XP, 2003. *
* *Updated* Now works for users with Non-Administrative Rights. *
* Code cleanup and changes, Commented. *
* *
* Usage: Add MSProdKey to your Application's uses clause. *
* *
* Example 1: *
* *
* procedure TForm1.Button1Click(Sender: TObject); *
* begin *
* if not IS_WinVerMin2K then // If the Windows version isn't at least Windows 2000 *
* Edit1.Text := 'Windows 2000 or Higher Required!' // Display this message *
* else // If the Windows version is at least Windows 2000 *
* Edit1.Text := View_Win_Key; // View the Windows Product Key *
* Label1.Caption := PN; // View the Windows Product Name *
* Label2.Caption := PID; // View the Windows Product ID *
* end; *
* *
* Example 2: *
* procedure TForm1.Button2Click(Sender: TObject); *
* begin *
* if not IS_OXP_Installed then // If Office XP isn't installed *
* Edit1.Text := 'Office XP Required!' // Display this message *
* else // If Office XP is installed *
* Edit1.Text := View_OXP_Key; // View the Office XP Product Key *
* Label1.Caption := DN; // View the Office XP Product Name *
* Label2.Caption := PID; // View the Office XP Product ID *
* end; *
* *
* Example 3: *
* procedure TForm1.Button3Click(Sender: TObject); *
* begin *
* if not IS_O2K3_Installed then // If Office 2003 isn't installed *
* Edit1.Text := 'Office 2003 Required!' // Display this message *
* else // If Office 2003 is installed *
* Edit1.Text := View_O2K3_Key; // View the Office 2003 Product Key *
* Label1.Caption := DN; // View the Office 2003 Product Name *
* Label2.Caption := PID; // View the Office 2003 Product ID *
* end; *
* *
