Code Gem

Ah … I realized that this is going to be the first post in my blog … wow!

While the latest version of WTL was released last year, it was updated with whole bunch of Vista support.  One thing that is really painful using non-MFC UI framework before is that there doesn’t have a good IDE support. A good news is that WTL 8.0 released with application wizards for both Visual C++ and Visual C++ Express. As easy as with MFC, a default project is created just with several mouse clicks.

It is very easy to install the wizard. After the WTL package is unzipped, there is a folder named ‘AppWiz’. Under which there are some javascript files for installing the wizard automatically. You only need to pick proper script for the different version of Visual Studio you installed. All easy shots. While this is very nice but one last minor issue is that at that time Visual Studio 2008 has not been released yet. Thus there is no install script for Visual Studio 2008.

I poked around internet and saw some people asking the question here and there. Actually the solution is pretty straight forward: open ‘setup80.js’ and edit it with notepad. Correct any registry key as if they are in Visual Studio 2008. Save it back, run it and you should be all set.

If you do not want to modify the script yourself, here is the code code I modified. Copy the code and save it at %WTL%\AppWiz\setup90.js. If you are in Vista, make sure you run it as Administrator. You are using the code at your own risk. No warrant is promised or implied by CodeGem.org.
