Using a bitmap as a background image is somewhat more involved than using a different colored background. The control has to be owner drawn. You could actually set a bitmap as the background image even if the control is not owner drawn but that would be a kludge. Might as well stick to reccomended techniques. […]

More questions on Discussion board are based on store/load a list control to file. One way to serialize the list control is to save information about the header of list control, and then serialize all items from list control. The idea is to open a file in CFile::modeCreate or CFile::modeRead depending on kind of operation, […]

When you change the font of a list view control, the control or its parent window does not get a chance to respecify the height of the rows. No WM_MEASUREITEM message is sent to the controls parent window. The net effect is that when the font is changed for the control, the row height is […]

One of the styles that the listview control can have is the LVS_OWNERDRAWFIXED style. The implication of this style is that the responsibility of drawing the content of the control is on the application. That is, you have to write all the code for drawing and displaying text in the control. Another aspect of the […]

This sample was contributed by Ravi Bhavnani. CHistoryEdit is a CEdit derived control that lets you to display a scrolling text history, much like Dev Studio’s “Output” window during a compilation. Here’s an example of the control (the “History” window) being used in a dialog box. CHistoryEdit’s AppendString() method appends a text string to the […]

Have you ever wanted to allow users of your MFC application to rename strings contained in various controls? If so, you probably included a “Rename” button next to your control. Take a listbox for example. When “Rename” is pressed you retrieve the current selection from the listbox, display it in a dialog for the user […]

The code demonstrates a CEdit-derived control that allows you to drag and drop files or folders into it – the path name of what you dragged will be determined and the text of said path will be set as the control’s text. it parses file shortcuts, too. Download files

Download Source Code I got this masked edit control code from someone (I can’t remember whom it was). If anyone wishes to lay claim to the original they are more than welcome. I have found this quite useful. So I can’t lay claim to doing all or even most of this. However I have enhanced […]

This class provides a CWnd derived editor that provides syntax coloring based on a keyword file you provide. It also supports auto-indent and retab. It is much faster than using CRichEditView to do the same thing, but it flickers a little and does not support any additional formatting. There are two classes that must be […]

Download Source Code and Example In a project that I am working with about 6 people, we were using spin controls and edit controls to allow the operator to change certain values. We decided we needed one way to handle invalid data typed in the edit control by the operator. The best solution we came […]

. New Features Dragging during a selection will now scroll the window. I’ve fixed several problems and have one know unresolved bug. Color encoding quotes is now supported. Known Bugs The editor won’t scroll beyond 1500 lines on Win95. I suspect this is due to a limitation in the size of the GDI area in […]

I was quite frustrated in my app – I have a dialog with a few single-line edit controls; after updating the edits, when I pressed Enter the dialog was closed (IDOK was the default button). “Want return” option is unfortunately valid only for multiline edits. Here is my fix: I override PreTranslateMessage. If there is […]
