Number of Lines on a RichText Box

[Lop]

How can I find the number of lines on a richtextbox? I'd like to know how many lines I could paste.

		 ////////////////////////////////////////////////////////////
		 //** This returns the total number of lines the rich
		 //** text box can hold
		 ////////////////////////////////////////////////////////////
private: int GetTotalNumberLines() {
			 String^ text = "TEST STRING";
			 System::Drawing::Font^ textFont = richTextBox1->Font;
			 
			 //Specify a fixed width, but let the height be "unlimited"
			 SizeF^ layoutSize = gcnew SizeF((float)richTextBox1->Width, 
				 (float)5000.0F);
			 Graphics^ g = Graphics::FromHwnd(richTextBox1->Handle);
			 SizeF^ stringSize = g->MeasureString(text, textFont, (SizeF)layoutSize);

			 // Divide RTB height by font height to determine how many it can hold.
			 int numLines = richTextBox1->Height / stringSize->Height;

			 // Return the number
			 return numLines;
		 }
