I have a table that has a composite key that consists of two int fields and one varchar(50) field. I made the composite key my primary key, which I don't usually do. Yes, yes, yes, I'm more than familiar with the logical key vs. surrogate key debate, but I must have done some heavy drugs (not really) the day that I made the table since I...
So I am playing around with using a ListView instead of a GridView to accomplish a complicated goal. The ListView is helping in a lot of ways, but there is one particular bit of code I am used to using with GridView's that won't doesn't work with ListView's. If I have to have a nice mouse hover action on my rows in a GridView, and if I ...

Hi, I'm repeating same binding parameters for every textbox and they're quite long strings (which is not good for many reasons). And I'm wondering if there's a way to make them shorter? For instance all my controls on forms are using the following binding template: Text="{Binding SourceProperty, UpdateSourceTrigger=PropertyChanged, Va...
Let's say I have this document. <a:Root> <a:A> <title><a:B/></title> <a:C> <item><a:D/></item> </a:C> </a:A> </a:Root> And I have an XmlNode set to the <a:A> element. If I say A.SelectNodes( "//a:*", namespaceManager ) I get B, C, and D. But I don't want D because it's nested in another...
Say I have: [Attribute1(Order=0)] public class Controller1 { [Attribute2] [Attribute3] public ActionResult Action1() { ... } } The attributes get executed in the following order: 2, 3, 1 This makes sense because attributes 2 and 3 have an order of -1 and will be executed before attribute 1 which has an explici...
Windows Vista and 7 both contain the ability to personlize the handwriting recognition. You can train the tablet to recognize your specific style. I know the personlization is used by the Native Windows Tablet Input Panel (TIP), the OS's handwriting control. Does the .NET SDK provide access to this personlization data so that my ....

I have this function which evaluates the contents of a textbox (or combobox or maskedtextbox) control and, in conjunction with a KeyPress event, will either allow or disallow the input. It is quite useful for dates or textboxes for which only numeric input is valid. It allows a set number of digits after a single decimal point, if spec...
I've been working through my first MVC application, and I'd like to localize it. I know how to use the App_GlobalResources but I'd prefer to use the App_LocalResources. In a typical WebForms application, you put the App_LocalResources folder in the same directory as the ASPX file... is this the same in MVC (IE: do I put them in the res...
I'm having trouble with a gradient drawing call. I have a Form that looks like this. The problem is every now and again the above gradient drawing bug will start happening. It should go right across of course. Sometimes it only takes some build-rebuild-mashing to fix and it'll simply just "start" after a build every now and again. Th...

Code to illustrate : int i = 5; object obj = i; byte b = (byte)obj; // X When run, this generates a System.InvalidCastException ("Specified cast is not valid") at line "X". Doing a double cast works : byte b = (byte)(int)obj; I would have thought that you ought to be able to cast a boxed int (if it ...
I have to create a C# program that deals well with reading in huge files. For example, I have a 60+ mB file. I read all of it into a scintilla box, let's call it sci_log. The program is using roughly 200mB of memory with this and other features. This is still acceptable (and less than the amount of memory used by Notepad++ to open this...

I'm trying to get a program I'm writing (in F#, though I would imagine the answer here is the same for any CLR language?) to report on its own memory usage (so I can get an idea of how much I'm stressing the machine, compare sizes of different workloads, and evaluate the effect of any optimizations I do in the hope of saving memory).
