There seems to be an ongoing effort to keep VB6 and COM alive. I was able to get the VB6 IDE XP themed with a manifest file. This is suppose to work on Win7 as well. There are a few things you need to add to your VB project to getting theming to work in your compiled VB application. I have also notice there are current Windows libraries that can replace outdated VB standards safely. I'm curious if there are others willing to chip in and get it tested, documented and example written?
I will keep forging ahead but some help would be appreciated.
Here is a screen shot of what a VB6 application looks like themed on Windows 7.
