I assume you are using MFC. In your CView class, keep some member variables like x, y and clickflag. Initialize clickflag to false in your CView constructor.

Then use ClassWizard to create a handler for WM_LBUTTONDOWN.

Now in your OnLButtonDown method do something like this:

  void CNameClickView::OnLButtonDown(UINT nFlags, CPoint point) {	CView::OnLButtonDown(nFlags, point); //point is the point within your view area that the user clicked the mouse	x = point.x;	y = point.y;// we have finally clicked on the view so set our flag	clickflag = true;// Inalidate the view area so that it will be redrawn next OnDraw	Invalidate();//Mark the window as updated	UpdateWindow();}

Finally, in your OnDraw you can do this:

  void CNameClickView::OnDraw(CDC* pDC){// standard OnDraw stuff.	CTestclickDoc* pDoc = GetDocument();	ASSERT_VALID(pDoc);// if the user has clicked on the view, draw his name at the mouse pointer	if (clickflag)	{                char* yourname = "Your Name";//pDC is your device context, which you should use for all your drawing with MFC		pDC->TextOut( x, y, yourname, strlen(yourname) );	}}

and that should about cover it

Hope this helps

Seeya,
