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

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

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.

Answer 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.

Answer 4

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.

Answer 5

试试devenv /resetskippkgs ...

Answer 6

I have the same problem and it drives me crazy. Finally, I have it works after trying many advice from Googling and trail and error.

1. \\Common7\\IDE\\devenv.exe /resetuserdata at the command prompt.
2. I rename Microsoft.VisualStudio.Debugger.DataSetVisualizer.dll to Microsoft.VisualStudio.Debugger.DataSetVisualizer.dll.test on both C:\\Program Files\\Microsoft Visual Studio 8\\Common7\\IDE\\PublicAssemblies And \\My Documents\\Visual Studio 2005\\Visualizers

Answer 7

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 8

Execute Visual Studio as administrator. Right click and execute as administrator and the magnifying-glass appears next to datatables.

Answer 9

I tried everything here but the only thing that worked for me was to overlay 2 folder using someone else VS 2019 that had the visualizers working.

1. C:\\Users\\XXXXXXXX\\Documents\\Visual Studio 2019\\Visualizers --< XXXXXXXX = the user folder
2. C:\\Program Files (x86)\\Microsoft Visual Studio\\2019\\Professional\\Common7\\Packages\\Debugger\\Visualizers

Answer 10

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
