I am looking for a way of doing something in VB.NET. I want to be able have the user look at the form. If any of 3 text boxes are empty, I want a messagebox to go off saying ("Please fill text box1 with a filepath") I want this to be done for three different text boxes in a form. If any of them are empty, I want the messagebox to be displayed for that particular text box. If all text boxes have text, then the program will run. How would I do this?
