CommonControls (Replacement of the MS common controls)

[VbNetMatrix]

ah no problem. I think you now know that Krool's controls simply wrap the existing controls found in comctl32.dll.

so we have 4 different controls we can use in VB6.
* comctl32.dll <-- use the API manually
* ComCtrls v5 OCX <-- wraps the controls in comctl32.dll in user controls
* ComCtrls v6 OCX <-- based on the source of comctl32.dll (windows XP version), but is independent.
* Krools Controls <--- wraps the controls in comctl32.dll in user controls

If you want to learn about the Windows Common Controls, MSDN has a huge reference to the APIs.

Regardless, does the same bug show up in .NET's DTPicker control?

Thanks for the link. I didn't had all theses information... I knew about v5 and v6... v6 (xp) being the fixed version and v5 being the theme able version. and I knew Krool is somewhat similar to v5 but was missing the whole picture

as for your question, I'm not sure about .net version, not using it but the v6 version is drawed properly.
