The project will not be able to use things which require application window handles ( e.g. CWinThread type of things ) as these will not be available in Console Apps ( CGI’s are included in this ). The main purpose of this project is to minimise the amount of memory and handles a program uses […]

This is a simple screen saver, which display sequentially all pictures in a directory (bitmaps, metafiles, GIF’s, JPEG’s, PNG’s). The default directory is the directory of the screen saver, but you can change it. Some problems there are still with that screen saver: The "Configure"-button in the "Screen saver"-property sheet does not work correctly. To […]

Writing Screen Savers With the advent of modern display devices, including long-life phosphors, liquid crystals, and Energy StarTM power saving modes, there is less need for screen saver programs than ever before. Despite that, the number of screen saver programs is still exploding, especially those offered on a freebie or shareware price basis. It might […]

When linking your application to a regular DLL, you can do it with either static linking or dynamic linking. Static linking is easier but if a DLL does not exist, your application cannot be started. Dynamic linking is a little bit harder but offers much more flexibility. If a DLL is not found, you can […]

This article is actually a modification of the original article “Single Instance of an Application Class” by Kevin Lussier. Kevin used the following piece of code to restore the application after a second instance is started: ….. HWND hWnd = ::FindWindowEx( NULL, NULL, m_strClassName, NULL ); if ( hWnd != NULL ) { ::ShowWindow( hWnd, […]

. A window can be created as either a child or a popup. A child window can be moved only within its parent’s rectangle area. Let’s say one wants to do just the opposite, that is, to move a child window out of its parent’s area, it is hard to switch its style without destroying […]

Provide a set of classes and recipes that, as much as possible, provide transparent and simple to use undo/redo facilities. Why? I am former Mac programmer […]

. The MDI apps typically have a list of open windows. The list is appended to a menu item which is 1 position to the left of the right most menu item. This is just ONE (simpler?) way of getting rid of it. There are other methods which duplicate some MFC code in application and […]
