• Visual Studio 2008 (Pre-release) HierarchicalDataTemplate, ItemsSource and CollectionViewSource

  Hello! Is there a way to specify, in XAML, that a HierarchicalDataTemplate may have it's ItemsSource object to be wrapped by a certain CollectionViewSource (The instance of CollectionViewSource could for instance provide sorting of the ItemsSource collection) If yes, may you provide a hint, please ! Best regards, Henrik Dahl Hi Henrik, The data binding team has been discussing that scenario pretty extensively lately. Unfortunately, the decision for V1 is not to support that, but we will for sure consider it again for V2. I think this will be a pretty common scenario, and we should allow i ...Show All

• SQL Server dependency relations are different from different mining structures with same mining algorithms?

  Hi, all here.. I got one problem in my data analysis case with SQL Server 2005 data mining algorithms-in the dependency network, the attributes mostly affected the predictive value are different in different mining structures tho. For example, I got a, b,c as input attributes to predict attribute d, in mining structure 1 (with all attributes discretized ), i got a as the attribute which has the strongest relation with predictive attribute d . However in mining structure 2 (with all attributes values continuous ), I got attribute b as the strongest attribute with predictive attribute d So what is the problem tho In this case, how ca ...Show All

• SQL Server SQL 2005 Upgrade problem.

  Hi: I had a serious problem today. I was upgrading SQL Server 2000 default instance to SQL Server 2005 when the setup failed to upgrade the database services with the error: The password does not meet Windows policy requirements.

• Visual C# how can i get a substring in a string and then change its color?

  for example if I type /* in the textfield all preceding characters should change to color green and when I type */ the change should stop. You have to write a method that colorize your text. If you want to make everything between /* */ grey do something like this: public void Colorize() { // Store current selection. int selectionStart = richTextBox1.SelectionStart; int selectionLenght = richTextBox1.SelectionLength; try { richTextBox1.SuspendLayout(); // Select all text and make it black (default color). richTextBox1.SelectAll(); richTextBox1.SelectionColor = Color.Black; // Find the open tag. int ind ...Show All

• .NET Development sql connection password problem

  Hey I have a .net 2 app that uses the SqlConnectionStringBuilder calss to create a connection string. Like so: SqlConnectionStringBuilder b = new SqlConnectionStringBuilder(); b.UserID = _sqlLogin; b.Password = _sqlPass; b.DataSource = _theServer; _sqlConn = new SqlConnection(b.ConnectionString); _sqlConn.ConnectionString = b.ConnectionString; _sqlConn.Open(); this works and I can connect to the database. But later on when I reference the _sqlConn's connectionString property, the password of that string is missing. I dont know why, it may be something to do with my code, but i cant find it. Does anyone know if this is a security fea ...Show All

• Visual C++ windows.h not found...

  WOW, I can't believe this information isn't easier to find.  I downloaded and installed Visual C++ 2005 Express, and then downloaded and installed the Platform SDK SP2.  NOTHING WORKS!  The Directories are not found and there is no apparent way to set them.  Apparently users have found a hack to make it work, but this is crazy.  It seems like the first Microsoft person to install this would notice that it doesn't work and would raise the flag to the appropriate people so they can take the steps to fix it for their users.  Or at least document it on the very first page where it is downloaded, or the very first pa ...Show All

• Visual Studio Tools for Office VSTO & MS Access

  I'm just trying to get up to speed on the new Visual Studio 2005 and the new Tools for Office.  We do a lot of work with MS Access (and Excel) and what I find odd is that in all the articles I've read there is not mention of MS Access w.r.t. the VSTO.  Do the VSTO not work with MS Access   What am I supposed to use if I am doing development with Access 2003 Can someone please clarify how VSTO works with MS Access   We've already been burned by buying Visual Studio 2003 "Special Edition".  It includes the Office Tools that I believe work with Excel and Word.  Too bad we bought the upgrade to work with Access 200 ...Show All

• Visual Studio Express Editions serial port will not trigger data received event.

• Visual Studio Team System Added new states, do I need to add new ref names?

  The MSF Agile comes with three states for work items: Active, Resolved, and Closed. In my custom template, I have changed these to In Analysis, In Development, Dev Complete, In QA, Passed QA, Closed. Now In order to track and report the full life cycle of a work item, do I need to add new fields and ref names The fields related to event dates defined in MSF Agile are State Change Date, Activated Date, Resolved Date, Closed Date. They seem to match the states so this leads me think I might need to define my own fields and the related ref names such as Dev Complete Date, Pased QA Date etc in order for the reports and queries to be accurate wh ...Show All

• Windows Forms Where Did My Bitmaps Go?

  My user-interface design has always been very basic.  "Spartan" some might say.  ("Skins We don't need no stinkin' skins!")  But with all of the visual improvements to the menu and toolbar controls in VS05, I think I've come around to the idea of adding some graphics to my UI.  My first step was to add some simple icons to the main MenuStrip items that I had extracted out of the My Movie Collection Starter Kit project.  Things looked pretty good.  Instead of a big empty grey box next to my menu items, I had a splash of color.  I then had a look around in the install folders, hoping to find some "common" bi ...Show All
