Just to sketch the contest (so you don't have to read the previous post), I am writing code with the AutoCAD API. This way my code is very dependant on that ...
I'm doing a document viewer for some document format. To make it easier, let's say this is a PDF viewer, a Desktop application. One requirement for the software is the speed in rendering.

Hi, I am struggling with setting up StructureMap without the use of the generic fluent interface, I can't use the generic methods, because I don't know the types at design time. Ie: To choose a default constructor the only method I could find is using 'SelectConstructor<T>()', but I only know the type at runtime... This is related: ...
I have two flags: [Flags] enum Flags { A = 1, B = 2 }; I set them like this: Mode = Flags.A | Flags.B; // default value for(int i = 0; i < args.Length; i++) { switch(args[i]) { case "--a": { if ((Mode & Flags.A) == Flags.A && (Mode & Flags.B) == Flags.B) // both, default assume { Mode = Flags.A; // only A ...
I need to generate a unique temporary file with a .csv extension. What I do right now is string filename = System.IO.Path.GetTempFileName().Replace(".tmp", ".csv"); However, this doesn't guarantee that my .csv file will be unique. I know the chances I ever got a collision are very low (especially if you consider that I don't del...
I came across a recent Audit report in our company for the code we maintain which says that we should not use Get in the method (not properties) naming like in GetSearchResults or GetXyzInformation. I looked up the MS guidelines (http://msdn.microsoft.com/en-us/library/4df752aw(VS.71).aspx) for method naming and as per that Get is allow...

I would like to create a rectangular 'flat 3D' look for one of my control templates. In it's most simple version this means having a line at the bottom that is darker than that at the top, and maybe some variation between the left and right lines too. A more complex version would allow me to provide on or more brushes so that gradients...

Is there a way to override the TextChanged event so it will pass and EventArg which contains the name of the control that fired the event? Whe...
