One of the Questions I was asked on my Article on Atlas @ Code Project at http://www.codeproject.com/Ajax/HelloAtlas.asp was How do you make the Atlas Controls Appear on your Visual Studio toolbox once you download them. The official documentation from Microsoft states these steps:

  1. Create a new web site from the "Atlas" web site template by opening the "File" menu, clicking "New", "Web Site...", and picking ""Atlas" Web Site" under "My Templates"
  2. Right-click on the Toolbox and select "Add Tab", and add a tab called "Atlas Control Toolkit"
  3. Inside that tab, right-click on the Toolbox and select "Choose Items..."
  4. When the "Choose Toolbox Items" dialog appears, click the "Browse..." button. Navigate to the folder where you installed the "Atlas" Control Toolkit package. You will find a folder called "SampleWebSite", and under that another folder called "bin". Inside that folder, select "AtlasControlToolkit.dll" and click OK. Click OK again to close the Choose Items Dialog. (This is the step that’s confusing most of the time. See Note Below)
  5. You can now use the included sample controls in your websites.

Yes, so, step number 4 is a little confusing. Not because of what it says but the way the Atlas control installer works. Actually, the installer explodes everything under your Temporary Folder i.e. if you’re the Administrator it explodes everything to C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp!! So, basically you need to either specify a different path where you want to expand this or copy this “SampleWebSite” folder step 4 talks about from your temp folder to any folder you want. Once you’ve done that follow step 4, point to DLL in the Bin folder inside this folder and you should be all set!
