I pressed the right mouse button and selected the "Show All" option.

After that, a lot of duplicates of the same controls appeared. However, there are controls that I have not seen before. The problem is that they are disabled, I can't put them on the form.

I tried to find them in the list by right clicking and selecting "Choose Items...", but they are not in any of the tabs.

How can I find and enable these controls?

CodePudding user response：

Show all will display all controls, for example, the MFC Control you screenshot should be a C control: https://docs.microsoft.com/en-us/cpp/mfc/controls-mfc?view=msvc-170

You created a Windows Forms App (.NET Framework), you just need to uncheck the Show all and all the controls you can use will be displayed in the toolbar.
