• Visual Studio 2008 (Pre-release) Combination bug of TextBox.MaxLength and Ime?

  It is a thing when MaxLength of TextBox is set and used. Conversion ends on the way when conversion that exceeds MaxLength by the Ime conversion is done.

• .NET Development How to get an embedded resource that is in a sub folder?

  Hi, I have an embedded resource that I am trying to retreive in my code via "System.Reflection.Assembly.GetExecutingAssembly.GetManifestResourceStream()". Everything works fine if the file is put in the ROOT part of the project. However, I am trying to keep things organized, so I made a subfolder in the project called "Resources", and placed it in there.... However, I cannot figure out how to retreive the resource now that it is in the Subfolder. I would think it would change from foo.bar, to Resources.foo.bar, or something similar... However, that is returning null for me... I also put a breakpoint in my code and put a Watch on a call to 'GetManifestResourceNames()'... this function returns all the resources, but once ...Show All

• Visual Studio 2008 (Pre-release) BlockUIContainer and print

  I have a FlowDocumentScrollViewer with a FlowDocument that contains several BlockUIContainers. When I tell the FlowDocumentScrollViewer to Print(), I want the contents of the BlockUIContainers to print too. The document prints, but there are empty white spaces where the BlockUIContainers used to be. Can BlockUIContainers be printed Followup to my own post: I found a workaround. Instead of calling FlowDocumentScrollViewer.Print() I do this: PrintDialog dlg = new PrintDialog(); if ((bool)dlg.ShowDialog().GetValueOrDefault()) { DocumentPaginator pag = ((IDocumentPaginatorSource)fdr.Document).DocumentPaginator; dlg.PrintDocument(pag, "title"); } where fdr is a reference to my FlowDocumentS ...Show All

• Visual Basic How does one hide a ListView column?

  Is it possible to hide a listview column I don't want to remove it, and I want to process the data in it. I just want to hide it. The problem is that the column will contain potentially sensitive information, and I want to be able to protect against shoulder surfers. The problem is, I cannot find a ListView.Columns( n ).Hide() method or a ListView.Columns( n ).Visible property. Is this possible to do, or do I just have to remove the column It doesn't seem like it should be all that hard. Thanks, Mark Warner. Hi! Did you find a solution to this I have the exact same question and apparantly no solution :-( Thank you in advance Kai Fransson ...Show All

• Visual C# Interfaces oversold???

  First, I must admit that I am a C# novice and so I probably don’t have as much knowledge and experience on the subject of interface as most of you guys reading this post. After reading a few books on C# and interface design, I still can’t see and understand the real power of interface unless of course, we are talking about interfaces as a powerful concept in OOP ‘only’ and not as a powerful concept in the general sense. When I was first learning OOP I was quite suspicious about the ‘excellent features’ that OOP claims to be able to deliver to the world and I was right. For example, in reality OOP offers very little if any, code reuse. I am now having the same suspicion about interfaces even though I see a lot nice words used to d ...Show All

• Windows Search Technologies MSN Search Desktop searchbox doesn't display on the taskbar

  Hello, I've got a problem with my MSN Search desktop searchbox, I can't get it to be displayed on the taskbar. It displays fine within IE and Outlook, but not on the taskbar. When I try to get it activated by going to the desktop search options and then pushing the button display MSN desktop taskbar. Or right clicking on the taskbar -> toolbars -> MSN Search desktop it never works. What happens is that the keyboard language toolbar is displayed on de taskbar, and that is not what I want.

• Visual C# Mouse question/help

  Hello, I am doing some research for a university and need some help with mouse movements. I need to be able to track the mouse no matter what window it is in. I have searched for this information extensively and have not really found a good answer. Idealy I would like to know for instance, if it is in Internet Explorer, where it is located i.e if it is click on the file button at the top for instance.

• Visual Studio 2008 (Pre-release) Custom issued security token

  Hello, I would like to create a federation scenario where the issued token is a custom token and not a SAML token. I’ve already studied the custom token sample posted by T. Janczuk at http://pluralsight.com/blogs/tjanczuk/archive/2006/06/16/28046.aspx and I’m rather familiar with the token infrastructure (managers, providers, authenticators, serializers, ...) However, I’ve a basic question: in the custom issued token scenario, do I have to implement the token provider from scratch or are there any extensibility points in the IssuedSecurityTokenProvider class that I can use In other words, is the IssuedSecurityTokenProvider hard-wired to SAML tokens, or is it possible to use it with another kind of token. ...Show All
