new in v0.0.0.5: auto size the dropdown.

You may also wanna take a look at ComboBox Color Background/Text subclass approach.

v0.0.0.3 = fixed some minor details ... but still need to fix the "remove ControlID" thing, as it'd create problems if one really uses the return value from the function.

 thought of the code

[argumentum]

v0.0.0.4
Should be all good.

[UEZ]

Very good work @argumentum 

 

 

[argumentum]

Thanks @UEZ, now I believe the only control left to be colorized is the Date/Time Picker ( GUICtrlCreateDate ) on Win7+. All help is always welcome ( hint, hint )

Hello. I really like this. new task for you. Allow the user to change the selected item color.

I do not know how to do this. But it would be good to have the UDF do that too. If you have hints or code, share it  

Edit: actually at "GUI/Tray Menu with icons and colors" there may a hint but I'm really pressured by time. This UDF arouse out a need for one, as in my current project I added light and dark themes for the controls and when I whent to use this Control, looked bad to me, so I looked around the forums and made this adaptation.
But I really need to get back to my project. The next step to colorize stuff is the Date picker but I'd have to get into system.windows.automation and it'd be a steep learning curve for me or create a DLL Date/Time Picker, also out of my league.

It did not trigger. Looked around the net and found that it needs to be subclassed to handle it. I don't know how to do that  
Also seen the notion that the control would be much better, if it autosized the listbox it drops down, so, we now have autosize

awesome work, thanks a lot argumentum !!

[WildByDesign]

@argumentum This is another fantastic UDF of yours. Thank you for sharing this.

I understand that you haven't touched this UDF in years now. I also understand that you are very busy lately. I just have one question though if you have a moment.

Do you know if there is a quick & easy way (nothing is ever quick & easy, I know  ) to add to this UDF the ability to modify the default blue highlight/selected color?

Example:

That default blue highlight is used when hovering over any of the items in the dropdownlist and also remains once you select an item. It doesn't go away until you select something else. If you know of a way to change that, I would greatly appreciate it. Thank you.
