I want to clear some textboxes of previously written data. When I run
the code below, only the txtBuffer text box is getting cleared. What am
I missing?

private: System::Void btnRead_Click(System::Object^  sender,
System::EventArgs^  e)
      {

      clear_textboxes();
        fd_read();

    }

void clear_textboxes(void)
{
    txtTc->Clear();
    txtStatus0->Clear();
    txtStatus1->Clear();
    txtBuffer->Clear();
    RedrawWindow(NULL,NULL,NULL,RDW_ERASENOW );   

}
