I have and application that was developed to run on the H5550. Recently, we
decided to purchase HP's latest model the Hx4700 (which is HP's replacement
for H5550). When I run the same application on it, it throws an exception
while initializing the forms. I traced the line down to when it loads the
Images into the ImageList that the form's ToolBar uses.

this.theToolbarImageList.Images.Add(((System.Drawing.Image)(resources.GetObj
ect("resource"))));

In the debugger I can view the "Images" collection and see the
"resources.GetObject" call returns a bitmap size 16x16. However, it throw
the exception on the "Add" apparently. When viewing the Splash screen form I
can see that is loaded is displaying correctly (only difference is the lack
of ToolBar on it).

One theory on working on is some incompatibility in the DPI. The old device
used 96 while the new device uses 192. I cannot give an more information on
the Exception because even in the debugger it is reported as a
System.Exception with no addition information.

Has anyone else run into problems maintaining application compatibility
between PPC2003 and Windows Mobile 2003 Second Edition or thoughts on
debugging the problem?

John,

It's come up a few times on the group before and at the moment the hx4700
seems to be the only unit affected

A solution is to initialise your ImageList manually after the Initialize
Component method and then assign it to the toolbar. There is a description
and code sample here:-

Thanks you very much Peter. I download ran the Hx4700fix.exe so it doesn't
crash anymore. Now I just need to fix the invisible ToolBars icons using the
alternative initialization method.
