At work I use mostly the .NET Compact Framework 3.5 for developing applications that run on smart devices. Our devices are not phones or handhelds - they are measurement instruments which you get with a whole punch of features. Our application is pretty advanced - we are even using a N-Layer architecture, a self-made GUI framework and ev...

Hi, I´m creating a PDA app and I need to upload/download a lot of small files and my idea is to gather them in an uncompressed zip file.

Hi, I wonder if it is possible in a Compact Framework application to prevent the garbage collector to unconditionally stop at least one of the threads, or if it is possible to block GC collects at least in some portions of the code. I think it has to deal with setting real time priorities, but I found a lot of advices against doing it.....
Hi, I found very annoying the fact that the SerialPort class in the .NET Framework doesn't allow to set the rts control to TOGGLE. There is a property called RTSEnable that lets me control directly the status of the RTS signal, but in a Compact Framework app there is not much precision to make it work well. Another solution can be to w...
