• Game Technologies: DirectX, XNA, XACT, etc. Changing mesh in vertexbuffer?

  I have a mesh which changes each frame. The change is not large, but there is generally always some change. The previous implementation used drawUserPrimitive and was quite slow. The mesh has a lot of shared vertices, so i was considering using a vertexbuffer and drawing indexed triangles. The question is now how to do this fastest. Is it very costly to lock the vertexbuffer each frame, alter som vertices and unlock If I sometimes have 4096 vertices and some times have 10, then the buffer needs to be created with the capasity of the largest number, but what when it is almost empty I can not delete a vertex, so it will really ...Show All

• Visual Basic Msgbox to the foreground????

  Hi, I've got a VB form in VS.NET 2005 which has a grid. When the user right-clicks on an item in the grid, I bring up a context menu. From there the operator chooses an option. Once the option is chosen, I ask that the operator confirms via a MsgBox similar to the following: If MsgBox( "Are you certain you wish to re-activate this product , MsgBoxStyle.Question + MsgBoxStyle.YesNo + MsgBoxStyle.MsgBoxSetForeground) = MsgBoxResult.No Then Exit Sub End If The problem is that the message box does not appear in the foreground.

• Visual Studio Grouping on fields which have a space in the table name

  I am attempting to run a 8.5 report in VS2005.  There seems to be a problem with grouping on a field when it's table name has a space in it.  The actual table name is {ccArea Types} in crystal and my dataset.  I get the following message: Error in formula <G_netsf>. 'Sum({ccArea_Types.SM_N_AREA},{ccArea_Types.SORTORDER)' There must be a group that matches this field Notice that an underbar has replaced the space in the tablename.  I have run simular reports without a problem when the tablename does not contain a space. Any ideas Thanks Keith, I tried to verify.  no help.  ...Show All

• Visual Studio overriding default designer functionality

  is it possible to override default designer functionality specifically, i want to change how the designer responds to double-clicking on events in the property editor. instead of placing the event handler into the codebeside, i want to place it into a different file. is this possible No, I would not recommend this.  At best, this is very difficult to do, if not impossible.  The designer loads "docdata" only for the immediate file and any child files.  It has no knowledge of other files -- so (for example) the event binding done in the IEventBindingService would have to be customized. If you wanted to go down this path ...Show All

• Visual Studio Team System How to: Customize the build reports

  Hey there, I already know how to add lines in the build log file. But now I need to add information to the report that ends up on the project portal. I have read the SDK part about extending the Team Foundation Reporting Warehouse but I'm not sure this is what I'm looking for... Any pointers Thanks!!! If you want to add information that's already in the warehouse to the report, then you can just edit the report to include that. For example, if you want to add the number of bugs found in a build (and your Bug work item type uses the Found In Build field), then add the Cumulative Count measure, sliced by Found In.Build.

• Windows Forms TreeNode not highlighted on DragOver Event

  I've got 2 treeviews. one treeview contains a heirarchical representation of a group of people, and the other is a collection of tasks. The user should drag the "tasks" over to a "person" to make an assignment. It works well enought, BUT as a user drags a task node from the right hand treeview and drags it over to the left hand treeview the Nodes do not highlight. I have tested and the node being hovered over is actually the selectedNode for the treeview but it's just not hightlighted. What gives Anyone seen anything like this Thanks, John Hi, You can use the code below t ...Show All

• .NET Development How big is the SOAP wrapper overhead?

  I'm using vs2005 Beta2, developing a system to transfer data to/from XDAs (PocketPCs) My issue is that our customers airtime contracts charge by 1024k chunks of data, so we batch data up to 1024k chunks before we send it.  When the system was in evb we used HTTPRequests to post to an asp page, so it was easy to do this. Now we're using VB.net talking to WebServices, and I'm no longer sure what size the data is I'm sending.  I'm not to sure about what happens underneath the hood (as long as it works I don't care much either!) but I understand that SOAP plays a part here, so what I'd like to know is how large is the data that actua ...Show All

• SQL Server Splitted char values in table

  Hi, I have the following content in one column of a table (each line one row, only 'underscore' seperated char): x_y 1_2_3 A z_X_c 9_2 I need to split this values (seperated by '_') and write each value into a new table. The resulting table with one column, shall look like: x y 1 2 3 A z X c 9 2 It is not the problem to split the char in single values, the problem is to seperate each value into one row. Thanks for the help, marc Thanks a lot folks for the good ideas and links. I solved it now in TSQL with looping with cursors and creating a table array (see below - only structure, not running code): ...Show All

• Software Development for Windows Vista Vista SDK Feb CTP installation issues on Win2k3 SP1

  I have been trying to install the Windows SDK on my virtual machine containing Windows Server 2003 Enterprise Edition with Service Pack 1. This has been causing me a lot of problems. I downloaded the full image and mounted the drive using the MS Virtual CD control tool. The install starts OK but gets to a point and fails on the setup. I followed the steps on this blog concerning known issues https://blogs.msdn.com/jsacks/archive/2006/03/16/553100.aspx . I even emailed Jason directly and discovered that the image I downloaded has a different reference when using crc.exe 0xD2F3971F. Jason's blog says to download the file again.

• Software Development for Windows Vista Windows Workflow Foundation from a business perspective

  As a developer I am really enthousiastic about the new Windows Vista related technologies, and especially Windows Workflow Foundation. Being a developer, I have lots of stuff to read about this subject. There are many good-quality articles, whitepapers, webcasts and forums such as this one to help me get started. The problem is, however, that if I want to convince the management team of my company that WWF and WCF are the way to go (which I think it is), I can't seem to find (really) good information from a business perspective. All presentations directly dive into code on slide 3 or 5 or so, and most articles I found are too developer ...Show All
