WM_MEASUREITEM

[Ratch]

To the Ineffable All,
     I don't receive a WM_MEASUREITEM when I do a CreateWindow for a "button" window.  Its style is BS_OWNERDRAW OR WS_VISIBLE OR WS_CHILD.  I see a lot of blab on the web about a bug or something in regard to this message, but the solution has such a heavy C++/MFC flavor that I cannot understand it.  Does anyone know a workaround using MASM?  Ratch

According to MSDN, "The WM_MEASUREITEM message is sent to the owner window of a combo box, list box, list view control, or menu item when the control or menu is created".

For an ownerdrawn button, the owner window will receive WM_DRAWITEM.

Hope this helps,

zooba,

According to MSDN, "The WM_MEASUREITEM message is sent to the owner window of a combo box, list box, list view control, or menu item when the control or menu is created".

For an ownerdrawn button, the owner window will receive WM_DRAWITEM.

     I do indeed receive a WM_DRAWITEM. But I expect to receive a WM_MEASUREITEM for my owner-drawn button according to the quote from the following MS link.  Ratch

This message is sent to the owner window of an owner-drawn button or menu item when the control or menu is created.

I open page http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceshellui5/html/wce50lrfwmmeasureitem.asp
At up of the page (on blue background) write some interecting:
"Platform Builder for Microsoft Windows CE 5.0"

KSS,

     Right you are.  It appears that CE 5.0 has more freatures for that API than XP does.  Ratch

Or more accurately, Microsoft had a chance to change the behaviour of their API without breaking older applications.

Read The Old New Thing. Raymond talks a lot about the compatibility issues Microsoft deal with.
