• Simon Sprott Issues debugging COM registered components

  HI I am currently looking to expose some of my c# application functionality to excel. I have set "Register for COM Interop" to true and set the start up application to excel. This allows me to run and step through the project debugging the code very nicely, however, every time I run the project I have to reset the dependency within the VBA window in excel. I am guessing that it is registering the component with different guids every ...Show All

• Hank2 A newbie question on Interfaces

  hi,    I'm new to C# and OO in general. I can't seem to undestand the pertinence of interfaces.   From my understanding, the interfaces define the signature of the methods while the class implements these methods. How is this better than simply doing away with interfaces and simply implementing the method in the class   Apologies for the rather novice question, an example to illustrate the pertinence of interfaces would ...Show All

• zombie How do I compare two TimeSpan objects to see if they overlap

  Is there a way to compare two TimeSpans to see if they overlap For example: (1/1/2006 - 1/31/2006) overlaps (1/15/2006 - 2/14/2006) (1/1/2006 - 1/31/2006) does not overlap (3/1/2006 - 3/10/2006) .

• Richard Judson Creating a reference to a value type

  I need to create a variable that holds a reference to a value type so that something like the following will work: int i = 0; int x = i; i = 2;  // i need: i == 2 AND x == 2   This obviously works with reference types: DataSet ds = new DataSet(); DataSet ds2 = ds; ds.Tables.Add("Table1");  // now ds AND ds2 have 1 table (they reference the same object).   I thought that boxing a value type would create a ...Show All

• doodahman ManagedThreadID doesn't work for interop for SetWindowsHookEx.

  I am converting a VB6 program to be C#. Therefore I was looking up how to hook the application for mouse, key activity and I found this article by Microsoft. http://support.microsoft.com/kb/318804/ In the code it uses AppDomain .GetCurrentThreadId() to set a callback thread for Hooking. It uses interop to the user32.dll. I modified/used the code and it works. However, the compiler insists that I should not use this function (GetCur ...Show All

• Sean McLeod Partial Classes and usercontrols

  Hi All, I’ve been looking into creating a partial class for a usercontrol but without luck. The ascx.cs class sees the method in the partial class and the partial class can see methods in the ascx.cs file (via intellisense) but when I do a build it says e.g. CallPartialMethod does not exist in the current context . I’ve added some quick sample code below to show what I mean. e.g. test.ascx // standard usercontrol …html & ...Show All

• Stormblade Cannot compile project under another configuration when web reference is present!?!

  Hi, This is a weird one: I've been unable to compile my solution under Release configuration for ages. Actually, not the entire solution, just one project inside the solution. Today, I decided to try removing a web reference and suddenly the project now compiles under Release configuration as well as Debug conf. Then I put the project (this time I didn't even bother using a full solution, I simply opened the project on its own (it doesn't depend ...Show All

• CSharpShooter Which data structure should I use?

  I want to use a data structure in memory that models a many-to-many relationship. For example, one URL links to many other URLs and is linked from many other URLs. I envision this like a database table with two columns, linksto and linksfrom , with a compound PK on both columns. This allows me to get all the URLs a page links to by querying the linksto column, as well as all the pages linking to it by querying the linksf ...Show All
