[Qt-interest] Running QtWebKit Application on Windows Mobile 5

[Marco Borm]

Hi Tumarov,

a little correction: Additional DLLs (with code) you copy to the device 
are always loaded into slot _0_, which is the same slot where your 
process code and data is mapped into and executed. DLLs the manufacturer 
placed into the OS-image _can_ be loaded into slot 1 if they are 
correctly marked as XIP (eXecute In Place), if not there are also loaded 
into slot 0.
I have a Qtek 9000 running WM5 with 9MB left in slot 1 (unusable for me) 
and 10MB left in slot 0. Because the code and data of my process also 
need to load into slot 0 its impossible to load a DLL larger then about 
5-6MB.

Glad to help you!
