• SQL Server Yet another "Cannot create a connection to data source" error

  I am experiencing the same problem that many, many other people have experienced. The dreaded An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'TradingDb'. (rsErrorOpeningConnection) For more information about this error navigate to the report server on the local server machine, or enable remote errors error. I have read through the suggest solutions and the number one point seems to be that when using Integrated Security you need to enable Kerberos Impersonation in the domain. But this makes no sense to me and here is why. * If I launch my browser and connect to the report server it does not work yet if I remote in to report server (using the same lo ...Show All

• Visual Studio Express Editions problem with \ in string c#

  Hi all, we have product developed in non microsoft technology which invode a c# exe passing the required parameter as command line argument. I am getting a file path say "c:\test.rpt" as commnad line argument when I receive it in c# it is appending @ at the beginning of the string like @"c:\test.rpt" . What could be the reason and how to resolve it. Thanks Girish I'll move this to the C# forum for you. Are you sure this is the case As a string literal, you'd show that string in C# code as you've rendered it, or with a \\, @ in front of the quotes means that \ means \ and not an escape character. So, are you seeing this in a debugger, or are you writing it to a f ...Show All

• .NET Development Serial I/O Problem

  I have an issue regarding the following code extract:- string s = string .Empty; if (_Port.BytesToRead > 0) { byte [] read = new byte [_Port.BytesToRead]; int bytesRead = _Port.Read(read, 0, _Port.BytesToRead); // Sometimes get an exception s = System.Text. ASCIIEncoding .ASCII.GetString(read, 0, bytesRead); } The above code is taken from a real-time application that interacts with a GSM Modem. The application uses the Serial Port class in .NET 2.0. Occassionally though I get an exception on the second line in the if block. The problem is that between that statement and the previous one, the value of BytesToRead changes, so the size of the byte array reserved is no longer adequate. ...Show All

• Visual Studio Express Editions WinForms: skinning non-client areas

  Hi, I found this great free skinnable dll for VB6 and was wondering if this would work with VB2005e. Free skins are also available. As I don't know enough yet, could you gurus please help check it out and let me know if it will fail http://www.vbaccelerator.com/home/VB/Code/Controls/Skins/article.asp My thought would be to try it - if its a COM DLL then potentially it may work - but you have the article and the DLL.

Something like in VB6 hwnd property on a form is now handle property in a .NET Windows form. These things we ...Show All

• Visual Studio 2008 (Pre-release) WPF Bug or What????

  While debugging throught WPF (NO COM) I am running into this again and again. I had posted this earlier too but nobody responded back. Just wanted to know where exactly is COM coming into play. Since we are aiming for production release of our app too, wanna make sure where exactly the things are going sour. Managed Debugging Assistant 'ContextSwitchDeadlock' has detected a problem in 'C:\XYZ..\bin\Debug\NoGen.Sandbox.WPF.vshost.exe'. Additional Information: The CLR has been unable to transition from COM context 0x1a1598 to COM context 0x1a1708 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows m ...Show All

• Visual Basic counting letters in a textbox?

  Is it possible to count the number of letters in a textbox OR label e.g >textbox1.text = "thesister" would return a value of 9 letters is this possible You could use this method. It would probably be faster with much larger strings. Imports System.Text.RegularExpressions ' input text Dim inputTxt As String = "_() letter _+=" Dim totalLetters As Integer = 0 'fetch the total number of letters - 6 in this case... totalLetters = Regex.Matches(inputTxt, "[a-zA-Z]" ).Count ...Show All

  Hey, I have a BasicPaletteEffect, which is like basiceffect, except it also contains a matrix palette.  In my processor, if mesh has bone index and vertex weight channels, and if it doesn't already have an external reference to another effect, I want to set it's effect to an instance of BasicPaletteEffect (inside the content pipeline).  Is there any way I can do this Thanks. Alright, thanks. I had figured out that I can just load the file, but was using the filename attached to the external reference. effect.Texture = input.ReadExternalReference< Texture2D >(); Is a neat trick though. ...Show All

  I am working on an assignment for my C++ class and have hit a snag, I hope someone here will be able to help me with this.

  If you are using or considering XACT for your product, could you let us know Recently we heard from a developer who was about ready to ship an XACT title, and we had no idea. We try to provide as much direct support to early adopters as we can, help them with any problems they bump into, etc; we can also adjust and prioritize our features based on real-world usage.

• Visual Studio Visual Studio 2005, MPI, CCS

To step only the single active process, use the step buttons at the top of this window." However, this window only has three buttons: Detach, ...Show All
