I'm working on a project in vb.net with vs2017 so I don't know what happened where I try to open some forms and folders but it doesn't open although I can see the codes but I can't see the visual form

CodePudding user response：

Presumably you are having the issue with the items that show a dashed outline icon. This indicates that they have been "Excluded from Project". Entire folders or individual Forms can be excluded. Based on the image, the entire folder "Teacher Payments" has been excluded from the project. Excluded items are not compiled.

To correct the issue, right click on the "Teacher Payments" folder and select "Include in Project".
