How could you see your control if you don't do anything to see it? The "answers" I've seen so far also lack the main piece of code you need.

To see your newly created control, you also need to call parentControl.Controls.Add(newlyCreatedControl); where parentControl is some control to become a parent, Form or any other, and newlyCreatedControl is your text box or any other control you create.

To know how to solve many problems like this one, you need to understand one thing. All controls are added "withing the code", always in run time; there is no other way. The designer merely helps you to create this code. Don't be mystified by the term "design-time" — it simply means that the control's code should support working with the designer.

So, if you know how to make certain things with the designer but not sure how to write it in code, do wit the designer first and then look at the auto-generated code, which is placed in the file shown as a child node of the main form node in the Solution Explorer. From this code, you will understand how to do it.

Solution 1

VB

Dim TextBox1 As TextBox = New TextBox

With TextBox1
    .Top = 8
    .Left = 16
    'set the other properties
End With

I'm making progress, but I'm still not seeing my new textbox. My code is below.

Did you read carefully article on msdn site? In my example i have show you how to set properites. I can't read in your mind... In my opinion the second rate of my solution (1) is not fairly, especcially when i haven't time to answer your question (in comment).
