• Bill_Henning [WCF-RC1] Custom ServiceAuthorizationManager override CheckAccess or CheckAccessCore?

  I'm implementing a custom ServiceAuthorizationManager to test claims. It's not clear whether I should be overriding CheckAccess or CheckAccessCore. Documentation suggests to override CheckAccessCore, but the FederationSample BuyAuthorizationManager overrides CheckAccess. I understand that what I want to do could be achieved in either place, but I would like to know what is best practice Should CheckAccess be testing Authenthication, and CheckAccessCore be checking Authorization Pete Interesting. Is this documented somewhere Thanks. SM I felt compelled to add a note on this as it is not obvious why one would want to override: CheckAccess.

• Elham Sarikhani LINQ to SQL DataContext too slow with large databases

  I've discovered that LINQ to SQL is currently too slow for real applications once you've got more than a few dozen tables in a typed DataContext. I presume this is purely a CTP thing but am mentioning it anyway so it doesn't get overlooked. The problem is with the AttributedMetaModel classes - they totally rebuild (essentially static) type information for every table class each time a DataContext is instantiated. Because in a distributed application a fresh DataContext must be instantiated for each middle tier request, this is a killer. My (so-far) successful workaround is to write a custom meta model with two MetaTable collections - a static dictionary for table-attributed classes, in addition to the existing instance collection for proje ...Show All

• gobby74 Blury images

  As far as I can see, images can be blury because of the way WPF handles pixels. If the image is positioned exactly on a pixel, everything is OK. However, if the top left corner is at, say, (12.5, 14.5), the image can be fuzzy. (see http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=498561&SiteID=1 for background info) I tried SnapToPixelDevice = true but it did not have any effect. I am considering going computing the position difference between the image and its top level window and adjusting the Margin to have the top left corner the Image be exactly on a pixel. That seems somewhat crazy though. Is there a better way Hi Tom, I'm also very interested in fixing this problem. I asked ...Show All

• Austinsnana How to handle a collection of Words in a FlowDocument

  I would like to develop a richly interactive FlowDocument or RichTextBox. Some examples of what I would like to do are Fire events when a user navigates (either with mouse or keyboard) to beginning or end of a word in the Document. Fire events when a user modifies a word, such as deleting a word, shortening a word, or lengthening a word. as is, the Document class does not provide a Words collection. Overall, i've found manipulating a RichTextBox to be very difficult in terms of reading what text is actually in the RichTextBox and responding to events at the Inline, block or Run level. Any guidance would be appreciated reading text is possible using TextRange.Text As for handling events for ...Show All

• Mark Remkiewcz Passing 3MB DataSet via WCF - Best Practice

  Hi In our application we have several DataSets with about 2-4MB of size. Each DataSet contains of only one single DataTable. The data has to come from the server to a client via WCF. Client and server are in the same LAN. What are best practices to pass the data The only thing I think I can be sure about is that I should use binary encoding for the binding. The following questions are still not clear for me: Which binding should I use - netTCP or WSHttp I know that a DataSet produces overhead, but does this really matter in my case If the DataSet produces to much overhead, what should I do best to get the data to the client fast Should I use streaming or better the standard buffering Which timeout and max size settings do I have to t ...Show All

• DiamonDogX Multi-threading in VSTO

  I have read throught many texts and i am not able to get to a conclusion. I have an excel application. The application queries various tables. After data is obtained through each table it is processes. Doing everything serially takes a lot of time. Is there any way i can put each task on a separate thread. None of the threads will be calling the Excel COM server. The tasks will perform data access/processing operations and once all the threads are done, the MAIN thread will do the writing on the workbook. In other words "Is is possible to do multi threading in VSTO solutions, assuming that threads won't interact with the office object" Thanks1!! ok i did post it on that forum.

• Marken VSTO SE + Office 2003 + VS 2005 Pro

  This is more of a Getting Started type of question. For some reason, I'm not finding any kind of basic tutorial that covers building an Add-In using VSTO SE (Beta) + Office 2003 Pro + Visual Studio 2005 Pro. The document that comes with VSTO SE Beta describes how to build a Ribbon, Custom Task Pane and a Custom Form Regin but all for Office 2007 components. I'd like to build an Excel 2003 add-in (or whatever) that displays a button to my end-user. Once the button is clicked I'll grab some data from the current/active worksheet, send the data to a web service and then take the results of the web service call and poke it back into the current worksheet. I've been able to do this in old school VBA (plus the now unsupported SOAP Toolkit) b ...Show All

• Windows Project How can I use the Page interface in the Microsoft.Office.Interop.Word.dll?
