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 you know how to help me view my datatables again?

Update: I'm still clueless about this. Could anyone point me in some direction, where should I even start looking for an answer? Thanks a lot.

Update: I changed to a new computer, and still the same problem. But I pinpointed it to being only in Visual Studio 2005. On Visual Studio 2008 I have perfectly normal DataSet and Datatable visualizers. So I tried re-installing VS2005, to make sure all the components were installed, nothing left out - but Nada. Still no visualizer.

Update: Found the solution to my problem: My answer

Solution 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.

Solution 2

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.

Solution 3

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.

Solution 4

Give devenv /resetskippkgs a try...

Solution 5

I am using Visual Studio 2017 and I had the same issue. I realised the visualizers folder is missing in my documents. I think this is something to do with the recent windows upgrade on the office computer. I have resolved it by creating an empty Visualizers folder.

I checked, and the file does exist.

Thank you for your edit! 1) No 2) Yes 3) I'm not sure I fully understood the process, but I did open 2 Visual studios and the same project in them, and attached the 2nd's debugger to the 1st VS - and I don't see the DataSetVisualizer in Debug/Windows/Modules

Thank you for your continuous help - I tried devenv /ResetSettings but it didn't help :-(

at first glance this looked like a horrible typo of "resetsettings"

Hi @ablesa. It's fine to answer old questions. Thanks for your input.

I had the problem in Visual Studio 2019 and it also turned out to be a result of My Documents\Visual Studio 2019 not containing a Visualizers folder. Creating an empty one fixed it.

This was my problem, while using Visual Studio 2017 and had the folder for this version, another install of Visual Studio 2019 did not. This affected 2017 so I added the folder to the 2019 location and it fixed my visualizer.
