• Visual Studio 2008 (Pre-release) TextPointer.GetCharacterRect throwing NullReferenceException

  I'm trying to write code to scroll particular paragraphs of a FlowDocument to the top of a FlowDocumentScrollViewer. What I'm thinking to do is to: 1) Find the Paragraph by Name in the FlowDocument 2) Use the Paginator attached to the FlowDocument and the GetObjectPosition to get a TextPointer to the Paragraph. 3) Use TextPointer.GetCharcterRect to find the offset to that paragraph in the document 4) Find the ScrollViewer elemet in the Template of the FlowDocumentScrollViewer 5) use the ScrollViewer.ScrollToVerticalOffset method with the offset computed in 3. Is this strategy going to work I've run into one problem straight away, which is that in step 3) (and see code below), GetCharacterRect throws a NullReferenceE ...Show All

• Software Development for Windows Vista Beginner having issues in Compression

  Hi I am trying to capture video using a webcam and at the same time drawing over this video capture using VMR 9 ( samplegrabber filter ) in real time into an AVI file. I managed to create the AVI file but the file is in an enormously large size. (Recording in 640 x 480) Currently using RenderStream  to capture the video. For the argument, pIntermediate [in] Pointer to the IBaseFilter interface of an intermediate filter, such as a compression filter. Can be NULL.

• SQL Server FTP Task - Delete remote files always fails

  Hello, I have two FTP Tasks configured in my SSIS package. One is for "Receive files" and the other is set for "Delete remote files." Both use variables for the source/destination paths. My remote path variable contains a wild card in the name field such as /usr/this/is/my/path/*.ext and it is working to FTP all the .ext files to my working directory. I then rename the files and want to remove the original files from the FTP server. I use the same variable as the remote path variable in the delete as I do in the receive. Using the same FTP connection manager for both tasks I am always getting a failure on the delete. The FTP connection manger is setup to use the root user. Using a terminal I am able to open an ...Show All

• Visual Studio 2008 (Pre-release) Polygon.Points Binding TwoWay

  So, I have a class that has a PointCollection, that is used to store some polygon geometry. I have a DataTemplate that I am using to display the polygon data, and am databinding its Points collection to my object's Pointcollection. This works well for displaying the polygon the first time, but if I change any of the points in the object's PointCollection, then the polygon is not updated with the new shape information. The weird part, is that if I just set the Points value of the polygon to the object's points property, it works as expected. I was able to create a custom shape to get around this problem, but I was wondering if this is a bug. Here are the important bits. By the way, I am running RC1. <DataTemplate DataType="{x:Type ...Show All

• SQL Server SQLDependency Disconnects for Web application

  Hi, On my ASP.NET 2.0 application and SQL 2005 database server, i am using SQLDependency API to recieve notifications on the dataset changes from SQL 2005 server. I get the notification sucessfully (irrelevant of number of attempts). So here's the problem, i wait for 3-4 mins and make sure that there is no activity on my web server. Now if the data changes the service broker fires the event (i validated through trace). But the notification is never received by my web application. It gets lost in between. I read about this 'Abrupt client disconnects' problem in the article http://blogs.msdn.com/remusrusanu/archive/2006/06/17/635608.aspx but this didn't help much. Also i sometimes see following messages in the profiler <qnev:QNEv ...Show All

• Visual Basic Power Pack - MSN Messenger Component

  Not sure if this is the right forum to post this but I'd sure like to see Microsoft release a power pack that allows us to integrate MSN Messenger with Visual Basic 2005 (establish conversation, send and receive data would be the basic functionality).

• Windows Forms DateTimePicker bind to DataGridView Issues On Displaying Blank Date

  hi, I got two (2) problems on this. 1. by reading alot on the forums/thread, I learned that to display blank date is by using CustomFormat = " ". At the same time I added code in ValueChanged to set value to mindate if text length is zero. My problem right now is that if the last value is min date and when I do a dropdown to select the date, the date choice is on the min date (eg. Jan 1901) which can cause trouble to get to the current year (need to click right arrow keys alot of times). Can I default it in a way that the calendar month that would be display on dropdown is current date I tried OnDropDown and change value to date.today but still doesn't work. 2. the datetimepicker is already displaying blank date, ...Show All

• SQL Server building cube using AMO

  hi, i am developing an application which enables the user to create a cube on the fly. I know that i can use AMO to create a Analysis Services 2005 cube. but my question is : Is it possible to use AMO to create a Analysis Services 2000 cube Cheers Anil The answer to your question is: No, you cannot use AMO to create cubes in Analysis Services 2000. There are too many differences betwee AS 2000 and AS2005. Analysis Services in version 2005 has been rebuilt almost from the groud up. The techologies and protocols used in AS2005 are new.

  I have updated to the Oct 17 version of sandcastle and update msbuild scripts for the changes in this version. I am successfully building an hxs and can view it correctly with h2 viewer.

• Windows Forms Custom Control Resizing
