MultiLine PushButton

[JTaylor]

Thanks to IfICantByte for the MultiLine Pushbutton Solution....Two things on this front. 

The first set of code demonstrates how doing this causes the ability to Color the buttons, Set Text, It not be Flat, etc. to go away.  Would I be correct in assuming that I would need to reproduce the LPITEMDRAWSTRUCT and apply it to do such things, assuming this is doable?  Sample Code?   :)

The Second is an example for the Tech Database which could be appended to the other post and which does the same thing as the other except using the latest version of WinBatch.  This process has gotten much easier over the years and thought updated code might be helpful to someone.

Thanks.

The Windows operating system implements push buttons differently than other buttons and other common/User control windows.  For this reason WIL dialog push buttons are mostly implemented internally with little reliance on the operating system's implementation.  WIL dialog push buttons are not owner drawn in the usual Windows sense.  They are owner implemented.

On the other hand, the OS provides a fairly straight forward way to modify the appearance  of check boxes, static and edit boxes by sending a specific message to a dialog's window procedure.  The dialog window procedure can respond to this message by passing back text and background color information to the OS.

However, multiline buttons would require creating an owner drawn control so that the dialog's windows procedure can provide color information to the OS when the OS reflects control draw messages back to the procedure.

Okay.  Thanks.
