• Visual C# N-ary Trees

  I’ve got a hierarchical set of data that seems to fit an N-ary tree structure, I can’t seem to find any good C# resources on the best way to parse/store/manipulate this data. The source data (SQL table) consists of a node id, node name and node parent which is null (root node) or references another node id. Any ideas General data structure for tree should look like this: class TreeNode { TreeNode parent; List<TreeNode> children; Data data; // any data in thee node ... // manupulation functions which can include childs collection // exposed to client } class Tree { TreeNode root; ... // tree manipulation functions like add, remove, find enumerate etc. } Since N-ary tre ...Show All

• Visual Studio Team System MS Project and TFS questions

  Here are some more issues that my client has encountered while using MS Project with TFS. Are there any work arounds 1. TFS seems unable to deal with special characters such as brackets ' [' e.g. Smith, John [ABC Company]. When synchronizing Project after making changes on TFS, it doesn seem to be ok with special characters like commas and parentheses ',' and '(' e.g. Smith, John (JohnSmith) 2. When changes are made to Remaining Work and completed work, how does MS Project interpret those updates It seems that the finish dates are dependent on the values entered in TFS. There is no easy way to 'approve' the changes before the update is done ( like with PWA). Thanks, Kathir. We have been able to get the download from Micr ...Show All

Because there have happened an exception; something that was like : "There is not enough trace information..." or like that. I am not wrong, are I Please hack through. Vaery Thanks ...Show All

• Visual Studio 2008 (Pre-release) Relative bindings for nested UserControls

I've created a XAML UserControl in another library that has binding defined for its element, however the DataContext for that control is specified in parent XAML form that is hosting the control.
