• Visual Studio Team System Can anyone remove the workspace which created by Administrator?

  I found that any users who can access the team project have the authority to remove the workspace which created by Administrator. How can I prevent this condition Many thanks! Any user with the "Administer Workspaces" permission can delete any workspace on the system, regardless of who created it. Have you perhaps granted your users this permission inadvertently Thanks, -Doug ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Geometry Instancing

  Hi, I have to draw a lot of objects for a visualization and use geometry instancing for that the amount of objects I want to draw should be between 1000 and 20000. That works fine as I can construct all objects of a cubes with position, xyz-scale and color. The shader just calculates the color of the side of the cube considering one light source and ambient light. I got two questions of how and if I can even further improve the performance: 1. Is there a even more efficient way to draw these objects if all of them are static in position, size and color Only the camera moves around. 2. The objects are constructed of cubes, but I hope to simplify them more to reduce the amount of cubes to be drawn. Most of the objects look like a c ...Show All

• Visual C# Is this code thread safe?

  There is an example of code at MSDN ( http://msdn2.microsoft.com/en-us/library/ms228972.aspx ). It shows how to use asynchronous callbacks to handle asynchronous method calls. I've a couple of questions for the thread-guru types among you. First - is this code actually thread safe Given that there can be a multitude of DNS queries kicked off and running concurrently, is it possible for the asynchronous callbacks (ProcessDnsInformation) to preempt each other I'm assuming that the actual "work" is being done using the thread pool and multiple results can potentially happen concurrently. If this is the case, the (ArrayList)hostName.Add(...) calls are probably not safe - i think. Secondly - when you code followi ...Show All

• Software Development for Windows Vista Sate machine workflow

  Hi, I have a simple state machine workflow with three states. I would like to put a timeout on the final state.(ie final state approver didn't approves this within the specified time, the state should go back to previous state). Is there any way to implement this thanks -Abraham Abraham - since each state can have multiple eventdriven activities - the way to implement this is to add an additional eventdriven to your final state - and then have a delay activity as the first activity inside of that eventdriven. ...Show All

• Visual C# Byte Array size.

  I'm sending a video frame from a server to a client. Now I know what size Byte array I should declare on the server side in which I'll store the picture and send it, however, I dont know what size array I should declare on the client side. Is there any way of finding out exactly how much data is coming in before i declare the array in which data will be stored It proving impossible to display that picture. One more thing, should i worry about the picture/frame header No Header is not a problem as far as you send complete bytes of image. Try this: Byte [] countbytes = new Byte [ 8]; int noofbytes = s.Read(countbytes, 0, countbytes.Length); long size = BitConverter .ToInt64(countbytes, 0); Byte ...Show All

• Visual C# Converting System.Type to OleDbType

  I can`t find class and methods that convert System.Type to any of dbtypes(OleDbType or SQLType). I know for the mapping tables, but I need conversion methods for all data providers(OleDb, SqlClient, ODBC) . It is not difficult to write that by your own, but I can`t belive that it is not alredy written by Microsoft. Why do you need this OleDbDataReader.Item and SqlDataReader.Item return an Object, just cast it to the native type: int count = (int)(dataReader["count"]); ...Show All

• Visual Studio 2008 (Pre-release) Image Source property cannot be set from a binding

  If I create a binding in code for an Image Source property like so Binding tmpBinding=new Binding("ImagePath"); tmpBinding.Source=ImagePathSource; image.SetBinding(Image.SourceProperty, tmpBinding); The image will not show. ImagePath is a property on ImagePathSource that points to a string containing the path to the image. I think the problem lies in the fact that in code the Path has to be escaped like so " RelativePath\\Image.gif " Within XAML if I create the image like so <Image Source="RelativePath\Image.gif"/> The Image will be displayed. Is there a workaround aside from creating the image in code it works for me < Grid Width = " 200 " Height = " 200 ...Show All

• Visual Basic A question about the CheckedListBox.CheckedItemCollection

  Hi, I would appreciate it if somebody could give me some insight to my question. What is the best (safest) way of saving a CheckedListBox.CheckedItemCollection outside of the created (and used) CheckListBox, such that, if the user clicks numerous Checkboxes and then clicks a "Cancel" button... the CheckedListBox.CheckedItemCollection will be repopulated with the checks that existed before the user made changes Also, please let me know if I have the wrong idea about how to go about finding a solution to this problem. Thank you! Hi, Thanks for your solution. Are there any classes that I can use instead of the Systems.Collection.Generic.List class supported in .NET Framework 1.1 I am developing on ...Show All
