How do I get the position of the text baseline in a Label and a NumericUpDown?

Question

I'm trying to align a Label and a NumericUpDown by their text baselines. I'm doing it in code, rather than the designer. How do I get the position of the text baseline?

Answer 1

For the Label control, you can get the position of the bottom of the text this way:

Assuming the .TextAlign is set to TopLeft or TopCenter or TopRight, the bottom of the text in the Label control can be found by this method:

dim btmOfText  as single
btmOfText = Label1.Font.GetHeight + Label1.Top

The .GetHeight method returns the height, in pixels of the current font used by the Label.
If the .TextAlign is Middle or Bottom, then you need to do a slightly more complex calculation.

This same method will also work with the NumericUpDown control.
