Are OwnerDraw button supported in CSharp

Hi All,

Are ownerdraw buttons supported in C# ?

I have an active X control which I would like to use in CSharp.

Buttons have a style BS_OWNERDRAW, and to do custom drawing you have
to handle WM_DRAWITEM message. It works greate in all languages except
CSharp and VB.net.

As soon as I change the style of the window (by chanding a property of
the Active X control) to BS_OWNERDRAW, it crashes with a NULL pointer
exception.

Any ideas?

Thanks in advance

There are properties for OwnerDraw on ContextMenu items. I know it can be done with regular menus. I cannot find anyone doing it with the systray icon contextmenu (notifyicon.) Is it possible to change fonts, colors, etc. of a context menu item if it is a system tray contextmenu? Thank you.

I come back with a new question regarding my OwnerDraw menu. That is a classical ownerDraw menu to add icon and some other color properties. My feature is to color all the menu bar with the background color of the items. So I feel the left side of the menu bar with a FillRectangle. I gather the width of the form for the Rectangle definition Everything works well.

Hi group, I've got this ownerdraw menu module which I got from a site and modified to my personal needs, but the only problem I'm having is with the lines in a menu, when you type - as text, it normaly becomes a full line and the height of the menuitem is reduced but when you set a menu to ownerdraw and use my draw and measure item handlers this doesn't work anymore, has anyone worked out a good sloution for this before?
