Re: how draw Region border with pen style? Paul M Watt1-Apr-02 7:55 Paul M Watt 1-Apr-02 7:55  I do not think that you will be able to do the border of a region with a pen. The reason is that windows does not actually calculate the border of your region for the FrameRgn function, it simply creates another region and fills that area. This gives the effect of a border. Of you wanted to you could calculate the border yourself from all of the rectnagles that create the region, but this may be time consuming depending on how complicated your region is. You would have to calculate the convex hull of all of the rectangles, even then, if you have holes in your region, they would be difficult to detect as well. How are you getting your region? What are you trying to accomplish with the pen. Because there are other tools you can use like paths, they are pretty powerful. If you post a few more details of what you would like, I will try to help you find a solution.

Now i want an event to happen when i click on one of its items. The problem is that at runtime there is no event/command handlers by default (i think). Can someone help me to make an event handler out of my runtime created object?

Let's call that CMyListBox. Now, when creating the objetc at run-time, make it a CMyListBox instead and call CMyListBox::Create just as you called CListBox::Create before. If I understood your problem right, this should do.

But now i have to display the font size in a CEditView.... that's where the problem arise.... i cannot convert the int size variable to a CString variable that can be displayed on the CEditView. Can somebody help me convert the int to CString... i used GetEditCtrl.ReplaceSel() to input the font size on the CEditView but the GetEditCtrl.ReplaceSel() only accepts strings... The code is used is listed below [ccode] if(dlg.DoModal() == IDOK) { CString text; text=dlg.GetFaceName(); GetEditCtrl().ReplaceSel(text); int size; size = dlg.GetSize(); GetEditCtrl().ReplaceSel(size); // This is where i get the error message saying cannot convert // int to CString. } [/ccode] 56Kbps of sighs Re: int to CString (look simple but.....) Christian Graus31-Mar-02 22:52 Christian Graus 31-Mar-02 22:52  It is simple. CString s; int i = 10; s.Format("%d", i); // s now == "10" CString::Format takes the same flags as sprintf, because internally it uses a variant of it. I prefer to use ostringstreams, but as you have a CString, CString::Format is the easiest and most obvious way to do it. So it's: CString szSize; szSize.Format("%d", dlg.GetSize()); GetEditCtrl().ReplaceSel(szSize); Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

How to get the correct client rect of the view? Feng Qin31-Mar-02 14:58 Feng Qin 31-Mar-02 14:58  I use the wizard to create the MFC application, choose Explorer style, so ,the app has two view:CLeftView, CRightListView, the following codes: void CRightListView::OnSize(UINT nType, int cx, int cy) { CView::OnSize(nType, cx, cy); GetParent()->GetClientRect(&m_ClientRect); MoveWindow(&m_ClientRect); } the m_ClientRect is the sum of CLeftView and CRightListView, that's not I want to see.

To move it, use ClientToScreen from the main window, if that's what you want the rect to be relative to.
