• Visual Studio 2008 (Pre-release) Imaging::CreateBitmapSourceFromHBitmap() bug?

  Hi, When beta2, I use Imaging::CreateBitmapSourceFromHBitmap() to create BitmapSource, it works. But after I updated June CTP runtime, I get a transparent bitmap. Is it a bug or the behavior changing CreateBitmapSourceFromHBitmap will use the alpha channel. If you are expecting an Rgb24 bitmap, then you should format convert to that pixel format. ...Show All

• SQL Server Capture date and timestamp of a file?

  Hi, I am pulling files from the FTP site using the FTP task. I want to also capture the date and timestamp of each of these files so that I can insert the values into a database and track when are these files get created normally on the FTP server. Any ideas Thanks in advance for your help. $wapnil spattewar wrote: No the transfer of files do not preserve the date and time. When i download the files all the files show the same date and timestamp. Can the FTP task be configured to preserve the date and time Thanks! $wapnil Well.... You can write a custom script to perhaps issue an 'ls' command inside the FTP session. Remember, FTP isn't designed for file interrogation, it's ...Show All

• .NET Development SelectNode - create if does not exist

  I am looking for a slick solution for this scenario: Input to a method should be an XmlDocument, an XPath expression and a string value. The inner text of the node found by the XPath expression should be set the the string value, if the node is not found it should be created first. The creation of the node is the biggest challenge here and I wonder if there is a good solution or functions which I am missing which can help me to accomplish this. Currently I put many restrictions on the XPath expression to make it work (no complicated queries: no back and forward, no search expressions). If the expression would be, e.g. /Root/Node1/Node2 I would split the expression by the slashes and navigate forward node by node and create one if it ...Show All

• Visual Studio 2008 (Pre-release) Zooming issue

  I'm working with a Slider which controls a ScaleTransformation on a control. That Control is inside a ScrollView. When you want to apply a transformation on a control you can choose between a RenderTransformation and a LayoutTransformation . A RenderTransformation is a low level transformation, which only alters the rendering of a control. This means that the container control won’t know that the control’s size has been altered, and for instance, if you have a ScrollView set on it, it won’t know about the change and you will miss some of the parts while zooming . Then, we would think that the right choice for zooming, is using a LayoutTranformation . A LayoutTransformation does change the ...Show All

  Hi, I have a couple of questions getting drive information from a PC. I am using the system.io.getlogicaldrive command to get drives in a PC. What i want is to be able to differentiate between the type of drives - ie, floppy, HD, CD, etc. Also, i want to be able to determine which drive is the system or OS drive. Thanks! Josh not really.

• Visual Studio 2008 (Pre-release) .ForEach on Dlinq objects and Linq CTPs

  In future version of LINQ will I be able to do a .ForEach directly on the Dlinq objects For example: var batches = from b in this.m_Database.Batches where b.EndTime == null select b; batches.ForEach(b => b.EndTime = DateTime.Now); Also will there be any other CTPs of Linq for Visual Studio 2005, or will I have to download the entire Orcas CTP if I want to use the newest features Thanks.

• Visual Studio Team System Server name in Changeset.aspx

  I changed the name of my TFS server in all sorts of places, but there is one left which I can't figure out. When I get an alert email that something new was checked in, I get an email with a link to the changeset. It ends with /VersionControl/Changeset.aspx artifactMoniker=16&webView=true. In there is a reference to a XSL stylesheet, but that reference is using the old, original server name. How can I update that one as well Thanks, David Jeff, I am afraid I didn't explain myself clearly. I changed the server name of our TFS server with the activateat from tfs01 to tfs01.mycompany.com. I also changed the TFSNameUrl and the TFSUrlPublic in the web.config in the Web Service directory. But ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Collision Detection in 2D?

  I am trying to make an event where if two 2D sprites collide with each other. like this... if (sprite1 and sprite2 collide) } //Event } You could: a) give each sprite a collision Rectangle and test whether those two rectangles intersect. You could extend this by giving each sprite multiple Rectangles and testing whether any of them intersect. b) use circles instead of rectangles above. c) do pixel-perfect collision (I'm not sure how this is done but some have done it in XNA pretty easily I think). Probably worth checking out how Gary Kacmarcik did it in XNAExtras here. Maybe if you don't even want to write your own then that link will help you out a lot ;) You could have your collision test function as part of a separa ...Show All
