Converting from traditional to simplified Chinese, part 1: Loading the dictionary

July 11, 2005 Jul 11, 2005 07/11/05
Raymond Chen
One step we had glossed over in our haste to get something interesting on the screen in our Chinese/English dictionary program was the conversion from traditional to simplified Chinese characters. The format of the hcutf8.txt file is a series of lines, each of which is a UTF-8 encoded string consisting of a simplified Chinese character ...

The best book on ActiveX programming ever written

July 8, 2005 Jul 8, 2005 07/8/05
Raymond Chen
I was introduced to the glory that is the world of Mr. Bunny many years ago. Mr. Bunny's Guide to ActiveX is probably the best book on ActiveX programming ever written. If you haven't figured it out by now, it's a humor book, but it's the sort of madcap insane geek humor that has enough truth in it to make you laugh more. My favorite is ...

How can I recover the dialog resource ID from a dialog window handle?

July 8, 2005 Jul 8, 2005 07/8/05
Raymond Chen
Occasionally, I see someone ask a question like the following. I have the handle to a dialog window. How can I get the original dialog resource ID that the dialog was created from? As we saw in our in-depth discussion of how dialogs are created from dialog templates, the dialog template itself is not saved anywhere. The purpose of a ...

What struck me about life in the Republic

Raymond Chen
When people asked me for my reaction to the most recent Star Wars movie, I replied that what struck me most was that the Republic doesn't appear to have any building codes. There are these platforms several hundred meters above the ground with no railings. For example, Padmé Amidala's fancy apartment has a front porch far above the ...

What are SYSTEM_FONT and DEFAULT_GUI_FONT?

July 7, 2005 Jul 7, 2005 07/7/05
Raymond Chen
Among the things you can get with the GetStockObject function are two fonts called SYSTEM_FONT and DEFAULT_GUI_FONT. What are they? They are fonts nobody uses any more. Back in the old days of Windows 2.0, the font used for dialog boxes was a bitmap font called System. This is the font that SYSTEM_FONT retrieves, and it is still the...

What’s the point of DeferWindowPos?

July 6, 2005 Jul 6, 2005 07/6/05
Raymond Chen
The purpose of the DeferWindowPos function is to move multiple child windows at one go. This reduces somewhat the amount of repainting that goes on when windows move around. Take that DC brush sample from a few months ago and make the following changes: HWND g_hwndChildren[2]; BOOL OnCreate(HWND hwnd, LPCREATESTRUCT lpcs) { const ...

Puzzle 1: This was a word search consisting of the names of the twelve streets of central downtown Seattle. The unused letters spell out the message "Issaquah year's supply hair conditioner", which takes you to the Issaquah Costco. (In the real puzzle, the secret message was much odder but relied on an inside joke.) Puzzle 2: The ...

Using script to query information from Internet Explorer windows

July 5, 2005 Jul 5, 2005 07/5/05
Raymond Chen
Some time ago, we used C++ to query information from the ShellWindows object and found it straightforward but cumbersome. This is rather clumsy from C++ because the ShellWindows object was designed for use by a scripting language like JScript or Visual Basic. Let's use one of the languages the ShellWindows object was designed for to ...

Some holiday fun: Puzzle supplementary material

July 4, 2005 Jul 4, 2005 07/4/05
Raymond Chen
(Note: This makes sense only after you've gone through the other puzzles.) In case my friend got stuck, she could call me and ask for a hint. The original plan was that I would charge her a dare in order to get a hint, but it turns out I was too nice a guy to make her do any of the following things, but here's the list anyway: Scream "I ...
