The primary monitor by definition has its upper left corner at (0, 0). Therefore, you can use this function: To make double extra sure (belt and suspenders), we also tell it, "If you're not sure what monitor to return, give us the primary." Sure, this sounds obviously simple, but I actually found somebody who fumbled around in the dark passi...

When you're installing your shell extension, you need to know which progid to hang it off of inside . We'll start with the title question and then move on to other predefined (but perhaps not well-known) progids.

I was asked to look at an application compatibility bug in a program from a major vendor. But that's actually irrelevant; what I'm writing about today has nothing to do with application compatibility. That's just what drew my attention to the program in the first place. At some point during the install, the setup program encountered an error and w...

Somebody I'd never heard of sent me email with a general programming question. (This is one of the top ways of instantly making me not interested in talking to you.) I have a modal dialog box which I hide with , and I want to enable the parent window so the parent window will get focus and keyboard input. Is this possible? If so, how do I do it?...

The function reports an error in two different ways, depending on whether you passed as the parameter. The documentation in MSDN is correct, but I've discovered that people prefer when I restate the same facts in a different way, so here comes the tabular version of the documentation. I'd show some sample code, but the documentation in MSDN ...

The function is one of those functions everybody tries to pretend doesn't exist. You thought was bad; is even worse. The idea behind was that you had a window with a menu as well as controls, and some of the menu items were checkable, indicating whether the corresponding control should be shown. For example, on your View menu you might have...

This article happened to catch my eye: I needed to generate some unique number in my application. I could use GUID, but it was too large for me (I need to keep lots of unique identifiers). I found something like this: This code generates Int64 (long) unique number (at least I hope it is unique). The uniqueness is in the scope of process. So...

It's probably trying to tell you that an embedded string could not be converted from Unicode to ANSI. One of our programs is throwing the exception "Type could not be marshaled because an embedded string could not be converted from Unicode to ANSI." It happens only if we use the Chinese version of the program. Why are we getting this exception? ...

If you make a single-instance program, and somebody runs a second copy of the program and passes a command line, the most common way of handling this is to hand the command line to the first copy of the program and let the first copy deal with it. When you do this, don't forget about the current directory. If somebody passes a relative path to t...

A customer wanted to alter the behavior of a multi-line edit control so that it did not treat a press of the Tab key as a request to insert a tab character but rather treated it as a normal dialog navigation key. The approach the customer took was to subclass the edit control and intercept the Tab key: There are many things wrong with this appr...
