This code is a very basic sample of “adding” ATL to the existing MFC project. I’m getting asked about MFC+ATL very often. Hope people find it useful. Contains VB(5.0) client and OCX(VC++5.0) that has MFC control and ATL In-Proc server. The way I did it is straightforward: Wizards generated 2 projects, MFC(Control) and ATL(In-Proc server) […]

–> Have you ever wondered whether there is a way to have an application extrinsically load a DLL (e.g. via the LoadLibrary() function) which exports classes so that the loader of the DLL can then use objects of the class ? This is basically no problem, the only thing that makes this a pain in […]

A Generic Printer class – and how to print a list control content (or how to print from anywhere without too many troubles). The CPrinterJob class is a base class for implementing print process aside from the view architecture; it comes along with a CPrintStatus (a CDialog derived) which shows the printing progress process. You […]

Abstract I’ve been envolved in some projects which required file gathering through directories and this class allows just that: gather file information recursively by directory and, as a bonus track, it also calculates 32bit file-checksum (note this is not NT’s executables checksum calculated with MapFileAndChecksum) and 32bit file-CRC (with a borrowed code, I didn’t feel […]

It is nice to be able to make a DLL project that includes its own resources (such as a dialog resource) and then be able to call it from another project. Seems simple but I wnet nuts untill I found out the following: In the DLL function that pops up the dialog you must manage […]

Environment: Win 32 I was working on a project where I had to paste into textbox HTML, copied from the Browser. A quick search on “HTML Clipboard Format” in MSDN gives you an article that thoroughly explained how HTML is kept in the Clipboard. Unfortunately, this article tells you that it’s kept in UTF-8 format […]

Environment: Windows CE 3.0 Introduction The CStudioFile class is intended for WinCE MFC applications because MFC for WinCE did not implement the CStdioFile text file functions. You should use the CStdioFile in Win32 programs. This class implements both UNICODE and ASCII text file reads and writes. If the format is UNICODE, it is assumed to […]

Very often the Class Wizard will not list the messages you want to handle. In such situations you have to add the message map entry yourself. One common situation where this happens is when you derive from a class which itself has been derived from an MFC class. For example, if CListViewEx is derived from […]

Here are some general ‘tips & tricks’ which proofed to be useful over the last years. KISS: Keep It Simple and Stupid Try to reduce the problem by building a sample application. With the new ‘AppWizard’ it does take less than a minute to build a running MFC application! So whenever you encounter a problem […]

Here is a nice macro that works very nice if you are working on an MFC project involving user messages. I always got irritated every time I had to add user messages, and sometimes forgot what parameters should be used. This macro pops up a nice dialog box where you just enter your user message […]

I am including the source for an application written by me that was originally intended for my own use in keeping track of the time I spend on projects, but is probably a pretty good sample for your visitors too. I’ve re-coded it, and added source comments and am making it public domain for the […]
