Ahh, this is managed C++? .NET 2.0?
Your timer interval is in seconds and you just want to display time left?

private: System::Void timer1_Tick(System::Object^ sender, System::EventArgs^ e)
{
// Update the timer
intTimerCounter++;


textBox2->Text = System::ConvertToString(30 - intTimerCounter);


if( intTimerCounter == 30 )
{
// If the timer reaches 30, disable
// the buttons
button1->Enabled = false;
button2->Enabled = false;
