• Visual Studio 2008 (Pre-release) Error message: New transaction is not allowed because there are other threads running

  I used the same code in ADO.NET vNext CTP sample "WinAppSample" in Windows Presentation Foundation. I am able to retrieve data in WPF but when it comes to save changes e.g. ObjectContext.SaveChanges() in WPF I am getting following error message "New transaction is not allowed because there are other threads running in the session." Any help Thank you in advance. Thanks Looking a little further at the exception in general, this kind of problem can occur if you have a reader open at the time when you attempt to call SaveChanges. SaveChanges will begin a new transaction (so that all of the changes made to the context commit or rollback together), and with SQLServer 2005 you cannot start a new transaction while a read ...Show All

• Smart Device Development MSMQ writing to remote queues in Windows Mobile 5.0

  I have a Dell Axim x51v upon which I'm trying to get MSMQ working. According to this article , there were previous limitations on remote queues which were probably going to be fixed in the final release. My ultimate goal is to have my mobile device be able to send messages to a queue residing on my server (Windows Server 2003) when it is not necessarily on the same internal network. Below is a summary of what I've tried and what my issues have been: MSMQ didn't come pre-installed on my Dell, so I installed it using msmq.ARM.CAB, which was part of the Optional Windows Mobile 5.0 Server Components ( available here ). I followed instructions on Mark Ihimoyan's blog to register, install, and test local queues. I tried t ...Show All

• Software Development for Windows Vista WDK is still not ready for Prime Time on Vista.

  Latest and greatest WDK 5483 has numerous problems installing on Vista Beta 2 build 5472. - It appears that DTM studio is not included in the package. - If even Framework 2.0 is installed, WDK doesn't recognize it. - Bundled MSDE is not supported on Vista. Comparing to HCT 12.1, WDK has more features but definitely more setup issues and not so user friendly. ...Show All

• Visual C# Prevent ComboBox DropDown Under Certain Conditions

  I would like to display a messagebox and prevent a ComboBox dropdown from opening under certain condiitons. I attempted to set the "DroppedDown" property to false in the "DropDown" event but it seems that the actual drop down occurs after the event is exited. Any ideas/suggestions Unforunately, I need the user to be able to edit the text in the box, but, if it's being edited, not allow them to select another item. That's why I can't just set it to disabled. It's odd I know but that's what's being requested. I guess I can temporarily change the style to simplelist but I hate that it loses the dropdown look. ...Show All

  I am developing a native application running on a machine with an internet connection. At the other end of the world, I know there is a web server running with pictures.

• Visual C++ How to access a program ported from C from other .net project?

  Hi, I am pretty new to C++ .Net and I need help on how to let my .Net programs accessing functions ported from a C program. What I have now is a solution that contains two projects. The first is a C++ .Net class library project and the second is a VB.Net project (doesn't have to be VB, it can be any other .net languages). What I need is to have the VB test program call functions from the C++ program. The C++ project is created by porting an existing C program. What I did was that I created a class library project using the C++ wizard. Then I added my existing C program (without any change at all), MyLib.c, into the project and removed all those generated files that I don't need. After fixing some issues, now I have the project co ...Show All

• Visual Studio Express Editions Form printing in landscape mode for new PrintForm tool

• Game Technologies: DirectX, XNA, XACT, etc. Multi threading in a game (using XNA)

  Hello. I am able to create thread and make them exchange information through common objects they know (server / each other reference) Now I would like 2 threads to update a server. Each of those threads takes for inputs a keyboard for one, a mouse for the other one. However, it seems that the thread that listens on the keyboard do not detect events from it. Seems like it is the parent thread that is able to listen to a keyboard event and only that parent thread. How would you do so that a children thread is master over a device even if it does not have the focus Regards, Chryso It is more like separating code. The keyboard / mouse is just a start. Using gamepad is what comes next. And if I want to push it ...Show All

• SQL Server Variable Length Procedure Arguments

  Is there any way to have variable length arguments for stored procedures - kinda like how there is in C/C++ For example, if I wanted to send 2 arguments at one time, and then at another time send 7 to the same procedure, is that possible Will this mean that I have to create a list of arguments ahead of time My problem is that I do not know ahead of time how many arguments the procedure will be sent. So if, I create a list of 10 arguments, and then the procedure is called with 15 it will break. Is there any other way of doing this Does TransactSQL have an array data type Maybe an array will be better for this, but I can't find anything on that. ...Show All
