I'm writing a WPF app that has a canvas in it. This canvas will be custom rendered at runtime. It's sort of like a game in that it needs to be measured in pixels. I need to be able to set my Canvas to 478x478 pixels (client rectangle size). I don't want any scaling or other resolution-independent steps to take place on my Canvas. I'm no...

Hello, I'm after a method which, when passed List<List<int>> will return {int}, when passed double[,] will return {double}, when passed Dictionary<string, byte[]> will return {string, byte} and so on. Basically, it's about recursing down the input type until the type found is not a "container type" anymore and then reporting this "basic...

In the past I've used performance profiling tools such as nprof, Equatec profiler and Yourkit profiler to identify and remove/reduce performance bottlenecks in code mostly running in one thread (serialized execution).

For a testing usage of not very complex WPF applications I often don't make installer - just, after building project, copy Bin>Debug folder content of a VS2008 project folder to a hard drive of a user computer and put an icon to a desktop. No records to windows registry. Are there any drawbacks of such a way of using windows application...
I have an app that was developed for Windows but runs fine on MacOS under mono without any modifications (yay!). However, since it's an exectutable, OSX doesn't recognize it as a native file type, meaning you have to drop to the command line to run 'mono appname.exe'. It also doesn't show the application icon. In case it matters, my t...

To jog everyone's memory, Java has these files with an extension of ".properties", which are basically an ASCII text file full of key-value pairs. The framework has some really easy ways to suck that file into (essentially) a fancy hashmap. The two big advantages (as I see it) being extreme ease of both hand-editing and reading/writing....

From what I understand, Apple has banned the Flash runtime on the iPhone because Apple doesn't want an alternative runtime environment to that which Apple provides via their own tools. Allowing a Flash runtime, according to Apple, would allow developers to circumvent application update policies and other controls which Apple has put in ...
How can I do this? Or will the serializer automatically go with recursion, and serialize all those child objects into XML? Give me an example how would you serialize classes that contain other classes' objects in themselves! That was the core of this question! I've tried this, and it didn't output anything (except the XML header) to th...
