I'm just wondering how other developers tackle this issue of getting 2 or 3 answers from a method. 1) return a object[] 2) return a custom class 3) use an out or ref keyword on multiple variables 4) write or borrow (F#) a simple Tuple<> generic class http://slideguitarist.blogspot.com/2008/02/whats-f-tuple.html I'm working on some cod...
It should be easy, right? Have a listview, add an imagelist, add images to the imagelist, assign image index to the column you want. But, it doesn't work. Microsoft article states that it is a known problem in .NET 1.1. But has it been fixed since? ...

I have PDF documents from a scanner. This PDF contain forms filled out and signed by staff for a days work. I want to place a bar code or standard area for OCR text on every form type so the batch scan can be programatically broken apart into separate PDF document based on form type.

There is very strange assembly reference problem and loading problem I experience with my Outlook addin. Here are the detail (a long story :) ): I have an old Outlook addin, written and build using .Net 1.1. The addin is loaded using an unmanaged shim in its own application domain. It works OK, with .Net 2.0, even if 1.1 is not present ...
The C# 3.0 spec has the following code example in section 10.6.1.3 "Output parameters": using System; class Test { static void SplitPath(string path, out string dir, out string name) { int i = path.Length; while (i > 0) { char ch = path[i – 1]; if (ch == '\\' || ch == '/' || ch == ':') break; i--; } ...
I wonder if people (meaning the company/developers) really care about having [SuppressMessage] attributes lying around in the shipping assemblies. Creating separate configs in the Project files that include CODE_ANALYSIS in Release mode and then yanking it off in the final build seems kind of an avoidable overhead to me. What'll be the...

Here is the code that is causing the exception: Assembly a = Assembly.Load(bin); bin is my byte array, loaded from the EXE. Here is the exception I am getting: Could not load file o...
To me at least, the Pair class is a very multi-purpose class. So why did Microsoft put it into the System.Web.UI namespace? Is there a reason that my tiny brain cannot comprehend? Thanks. ...
I'd like to store a simple key/value string dictionary in my web config file. Visual Studio makes it easy to store a string collection(see sample below) but I'm not sure how to do it with a dictionary collection. <ArrayOfString xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">...
Today I discovered something that makes me sad: objects of type System.Generic.Collections.List don't have a number of the useful extension methods I've come to love, such as Find, FindAll, FindIndex, Exists, RemoveAll, etc. The object browser in VS2008 shows that those methods exist in the mscorlib version I'm using, but if I look at ...

Is there a way to have different application settings per each build configuration? I would like to be able to batch build a few configurations with different settings, instead of having to change the settings and build, rinse repeat. Thanks in advance! ...
Every now and then, I bump into syntax that I've seen before, but never used. This is one of those times. Can someone explain the purpose of ":this" or ":base" following a C# constructor method? For example: public MyClass(SomeArg arg) : this(new SomethingElse(), arg) { } My gut feeling is that it is used to map a default argument o...
I have a list box control: <asp:ListBox runat="server" id="lbox" autoPostBack="true" /> The code behind resembles: private void Page_Load(object sender, System.EventArgs e) { lbox.SelectedIndexChanged+=new EventHandler(lbox_SelectedIndexChanged); if(!Page.IsPostBack) { LoadData(); } } private LoadData()...
Here's an interesting puzzle. I downloaded Snippet Compiler to try some stuff out, and wanted to write the following code: using System; using System.Collections.Generic; public class MyClass { public static void RunSnippet() { HashSet<int> h = new HashSet<int>(); } } But the above code doesn't compile. I get: "...

By default, when you use: Page.MasterPage ...
