DataTable visualizer disappeared from my Visual Studio

Question

A while ago I noticed I don\'t have a magnifying-glass next to my datatables. I used to have it, and somehow, sometime, it disappeared...
Has anyone seen this happen? Do

Answer 1

I was really bothered by the problem, so I turned to Microsoft support, and they solved my problem! The short solution is that apparently one of the DLL's in the My Documents\Visual Studio 2005\Visualizers folder was corrupted. I deleted all the contents of the folder, and the visualizer came back.
The long answer can be found in this post written by Faruk Celik - the person from Microsoft who solved my problem.

Answer 2

I was having the same problem, nothing would appear when I hovered over my dataset variable. I was finally able to see the dataset visualizer when I added my.forms in front of my dataset variable in the Watch window

Answer 3

Give devenv /resetskippkgs a try...

Answer 4

I know this is an old post, but I have been fighting this same issue. Nothing solved my problem... I finally figured out that I had been running Visual Studio in compatibility mode (Windows 7 os). Once I ran devenv.exe without compatibility mode set, the visualizers showed up again.

Answer 5

I tried everything in this post but nothing worked for me. I am running Windows 7 64-bit. Eventually I was able to find a solution in this post

Answer 6

1. Create a new clean project, does the Visualizer show up there?
2. Check if this file exist: "\Program Files\Microsoft Visual Studio 8.0\Common7\Packages\Debugger\Visualizers\Microsoft.VisualStudio.Debugger.DataSetVisualizer.dll"
3. Check if the dll is loaded in Visual Studio, Open your project, then open anther Visual Studio, attach the debugger into the first Visual Studio (Make sure that managed debugger is selected). Inside the debugging Visual Studio open Debug/Windows/Modules to see if the DataSetVisualizer is loaded.
4. try devenv /ResetSettings from an admin console.
