Hi CodeFlatter,

i would suggest to completely avoid using SHLoadImageFile() for Windows Mobile 5.x and higher since it has some known issues regarding large images that lead to unpredictable failures while loading some images. Also avoid imgdecmp since it is deprecated. Better use the .
It also supports loading thumbs, sizing operations, different decoders and also runs under pure WinCE. Only drawback: A little bit more code and usage of COM. But it is worth the effort.

All of my games use the SHLoadImageFile, and I haven't run into any problems. In fact, I don't think I even started using that until WM5 because the original code became deprecated.

PsychoChris, do you know how large the image needs to be to start having problems? I know 240x1400ish work just fine.

Thanks at PsychoChris and Presto!

I will see if I find code examples to use imaging api, com code is more complex...

Best regards

@ Presto:
We encountered not clearly reproducable problems using SHLoadImageFile() with images of dimensions 1600x1200 or larger. Especially images created by cameras of mobile devices. Those images loaded most times fine in the emulator but return NULL handles on devices although memory on the device was more than sufficiant. You can find similar issues by googling around. Solutions suggested by microsoft developers always pointed out avoiding that function and using Imaging API (see for instance).
Using the Imaging API we didn't encounter those problems anymore.


@ CodeFlatter:
Take a look at . It shows you how to implement loading images with Imaging API for WM 5.x and higher and also includes a fallback solution for older devices not providing that API.

Hello PsychoChris,

thx 4 the link, this page is helpfull - but use MFC code (no one of my mobile app's use MFC).
I need an example without MFC (using of MFC is impossible for me) or an simple code snipped...

Regards, CF

Thx Presto and dito.
