I always use something like the following: public static String GetTimestamp(this DateTime value) { return value.ToString(“yyyyMMddHHmmssfff”); } This will give you a string like 200905211035131468, as the string goes from highest order bits of the timestamp to lowest order simple string sorting in your SQL queries can be used to order by date if you’re … Read more
I had to do this in the past for generating black & white reports printed via Bluetooth (color or greyscale images were too large for the printer’s buffer). Turned out I had to create the images using native code. Here’s a snippet: private void CreateUnmanagedResources() { // for safety, clean up anything that was already … Read more
Sure: Use a physical device whenever possible (not the emulator) Test with multiple devices (different vendors, different models) Concentrate testing around sleep/wakeup behaviors When using MSTEST unit tests, never use private accessors Avoid ActiveSync like the plague – debug using CoreCon direct Get familiar with RPM and start using it early Reuse objects when possible … Read more
I’m positive this question is a duplicate, but for the life of me I can’t find the original so I’ll re-answer here. Microsoft’s support for Compact Framework development is not completely obvious or well documented.

The problem is that it knows that the first element is unaligned, but it seems to not understand that each element in the array would also be unaligned. You can see the behavior works in this example: [StructLayout(LayoutKind.Explicit, … Read more

var logFile = File.ReadAllLines(LOG_PATH); var logList = new List<string>(logFile); Since logFile is an array, you can pass it to the List<T> constructor. This eliminates unnecessary overhead when iterating over the array, or using other IO classes. Actual constructor implementation: public List(IEnumerable<T> collection) { … ICollection<T> c = collection as ICollection<T>; if( c != null) { … Read more
