Question

I’m trying to print a datagridview by drawing to bitmap using visual studio 2008 C++ Windows Forms Application, however I’m having trouble converting the 2 types mentioned in the title. This is the method being called:

private:
   void printDocument1_PrintPage(System::Object ^ sender,
      System::Drawing::Printing::PrintPageEventArgs ^ e)
   {
      Bitmap^ bm = gcnew Bitmap(this->dataGridView1->Width, this->dataGridView1->Height);
            this->dataGridView1->DrawToBitmap(bm, new Rectangle(0, 0, this->dataGridView1->Width, this->dataGridView1->Height));
            e->Graphics->DrawImage(bm, 0, 0);
   }
System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {
        printDialog1->ShowDialog();
        printDocument1->Print();
    }

However upon compiling the code I’m getting this error:

error C2664: 'System::Windows::Forms::Control::DrawToBitmap' : cannot convert parameter 2 from 'System::Drawing::Rectangle *' to 'System::Drawing::Rectangle'

I’m clueless. How can I fix this error?

Answer 1

Shouldn’t the new Rectangle(...) code be gcnew Rectangle(...)? Remember that in Managed C++, new is NOT the same as gcnew.
