How to make a combobox NO INTEGRAL HEIGHT?

[chenxu]

I knew that the UDF _GUICtrlComboBox_Create can do this. But I got an application which has been finished creating a combobox by using the GUICtrlCreateCombo function, and I do not want to rewrite the application.

Every time I change the size of the application, I need to change the height of the combobox created by GUICtrlCreateCombo, and the combobox will automaticly make itself integral height. How to stop the combobox automaticly making itself integral height?

I don't know the definition of "integral height". >_<

Perhaps all you need are some Global variables or math expressions for the position and size of the control, so it is adjusted automatically whenever you change the GUI size in the code?

The height of a combobox is set by the font although the width can be changed. Here is a demo using a version of my recent post in gui help & support.
