• Visual Basic Cannot debug converted programs from 2002 to 2005

  Good Morning, I have converted several programs from 2002 vb .net to 2005 vb .net. I have notice while stepping through my code I can't step into (F8) the code of a converted dll like I could in 2002. I have even tried the debugging keys from 2002 and they just step over the code also. When using these keys the debugger steps over the code like I was pressing Shift + F8 keys. I need to step into this dll since the converted dll code is now throwing errors which are not there in the 2002 code. Is this a known bug If so is there a fix for it or will it be released in the near future We cannot migrate to the 2005 version until this is fixed since there are other issues as described above. Thank you for your time. ceoliver ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. LineList Performance?

  I have a simple class that sends a list of vertices and indices to a buffer(each). The performance is very slow when rendering a LineList. Rendering starts to slow when rendering as few as 500 lines. Is this normal I can render a TriangleList with 100,000 triangles with better performance! Thanks. It does seem excessive for it to slow down with only 500 lines but, in general, most consumer graphics cards are terrible at drawing lines. The graphics card companies do this to preserve the market for their "high end" cards that they sell to the professional industries for use in CAD applications. ...Show All

• SQL Server Deadlock problem? 3 way conditional split of data from one table to another never completes

  I have a source table which I'm splitting 3 ways based on a column value, but the target is the same OLE DB destination table. One conditional path is to a Multi-Cast two way split to same OLE DB gestination table. The default split is to a flat file for logging unknown record types. For a test I have data for only the 3 column values I want, but I'm having trouble with the process completing. If I pre-filter the data going into the source table by one or two values I can get the process to complete even if one split is to the multicast. If I include all three data types in the source table, I get different results depending on the order in which the conditions are specified - sometimes only two split paths are executed; other times all th ...Show All

• Visual Studio Team System Links to VSTS from outside Studio

  How do I create a link to a VSTS versioned item that I can place in a local folder Can I create create a URL of the form vsts://myTeam/latestversion.foo Basically I'd like to be able to create a folder full of links to items under Team version control. (like the Links tab in the Work Item Task form) The question was pretty general so I will do by best and kind of list some scenarios and their solutions. 1) You want to create links to view the files from windows: Well the files are under version control which means that you need to have access to version control and those files in order to view them. To do these kind of links you will create a batch file that serves as the link that exec ...Show All

• Visual Studio Express Editions Asynchronous Calls

  hello fellow programmers, i was just having some problems on how to make an asynchronous call. well, can someone show me a very simple program thats uses asynchronous calls thanks in advance! Can you be a little more specific Let me see if I have some code examples. Also HttpWebRequest has examples of Asychronous use in the Help Files. I fear my better asynch examples won't be real different from what you find in help. Many things are asynch like events and timer tick handlers which is also an event.

• Visual Studio 2008 (Pre-release) VB 9: Order By bug?

  Can anyone explain to me why Order By works fine while selecting the whole object: Dim data2 = From c In db.Cities _ Select c _ Order By c.Name But doesn't work when selecting only one property Dim data = From c In db.Cities _ Select c.Name _ Order By c.Name error BC32050: Type parameter 'K' for 'Public Shared Function OrderBy(Of T, K)(keySelector As System.Query.Func(Of T, K)) As System.Query.OrderedSequence(Of T)' cannot be inferred. The key here is the order in which the result sets are evaluated. In the VB case, Select c.Name creates a List(Of String) with the name of the string property as "Name". Thus, when you get to the Order By clause, it does not know about c In db.C ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Will build #5536.16385 of Vista be compatible with D3D10 in August'06 SDK?

  Hi, Just checked my email and it seems that beta testers (maybe MSDN people as well) can now get another pre-RC1 build of Vista. The August'06 SDK states that the D3D10 CTP will only work with RC1 of Vista and the other recent pre-RC1 build wasn't good enough. So, just wondering if anyone here knows if 5536 will work with the August SDK or if we still need to stick with Beta-2 and the June SDK. Would save me a lot of time before I go and download 5gb of ISO's and spend a few hours setting up my test machine... Cheers, Jack Ralf Kornmann wrote: I haven't seen x64 ISOs for this build so far.
