The reason it's not working isn't your code, just stop for a second and think what you are trying to do. A textbox and a command button both have a property which you could call 'Text', so you are setting that property with the WM_SETTEXT message. A combo box doesn't have a text property as such, it has a list of items which you select.

Try these links...

So there is no way to add a new text/item to the combobox?

KingSencat, did you even open the link I sent you? It has API to add new items to a combo but WM_SETTEXT is not the way.

KingSencat, I know you are using VB, I'm trying to get you to use your intuition. If you bothered to READ the page you'd know exactly how to approach this.

API is the same for all languages.
