Hi Frank,

I've never used ActiveSync, but I've used plenty of list controls. The
problem you are describing sounds like the image list is getting corrupted
(or not passed through) correctly. Could you post some of the code on how
you set up the image list you are using with the list control? Where is it
hosted? How is it created? Do you delete it after the dialog runs the
first time? Is the dialog actually restarted or is just hidden and reshown
later?

Thanks,

Tom

I have a problem with a list control on a dialog (that is contained in an
ActiveSync synchronization service provider dll) where icons are sometimes
missing.

The dialog is normally displayed by the user clicking on settings from the
ActiveSync UI.

In some cases, I display the dialog based on a program event (first run
after installation), and this leads to the problem.

Problem scenario:
1. setup conditions for first run
2. program displays dialog and icons are fine
3. close dialog
4. open dialog by using the ActiveSync UI, which calls into the dll
5. dialog appears and icons are missing (other text columns are fine)

Once the problem occurs, it can be avoided by restarting ActiveSync, which
hosts the dll. (And since the "first run after installation" condition
will not occur again, the problem will not occur again.)

I have added test code to query the list control items for the iImage
values, and these look fine (same values whether icons are displayed or
hidden). I have also added test code to query the list control for the
image list, and drawn the icons onto the dialog (using CImageList::Draw).
The resulting icons look fine, even when the icons are not shown on the
list control.

I am using a report view, where the fist column displays an icon only, and
there are two other text columns. I am testing on Windows XP and
ActiveSync 4.5, but these are probably not related to the problem.

I don't know what to try next. Do you have any suggestions?

Thanks,

Frank
