I need to generate large images (A4 image at 200 DPI, PNG format would be fine) in my compact framework application. This is impossible to do in standard way due to memory limitations (such big image will throw OOMException). Is there any library which offers file-backed stream image generation? Or I could generate many smaller stripes...

I really want to upgrade to Visual Studio 2010. But since I do a lot of development for the Pocket PC version of Windows Mobile I cannot. (I develop for a Symbol device that does not support Windows Phone 7, so that is not a option.) Does any one know any kind of time frame of when Microsoft plans to add support for Smart Device Proj...

Do I need to install .NET 2.0 on the device, where .NET 3.5 is installed? So far my application works on .NET 2.0 (which potentially should be faster) but the long term plan is to port it to .NET 3.5. I need to order devices and the OEM needs to know which version of .NET should be added to the Windows CE image (version 5.0). Shall I a...
Hello - I've been trying to figure out how to consume a self hosted WCF service from a Windows CE device. I've not found any good resources that walk through this process online. I've found some good samples for self hosting, and that part seems to be working fine, but not sure how to go about consuming on the compact framework. In th...
Hello ! I have a CF application. In some view i have a ContextMenu that shows OK. Is there a way to catch an event as the menu is drawn/opened? I need to do some things just as the menu is drawn, because doing it later (on menuitem click) is already too late. regards ...

The current way our application is written, involves creating a new connection and command object in every method that access our sqlite db. Considering we need it to run on a WM5 device, that is leading to hideous performance. Our plan is to use just one connection object per-thread but it's also occurred to us to use one global comman...
