• Game Technologies: DirectX, XNA, XACT, etc. combine c++ and c#

  Hi everybody, I wish to know, if it's possible to combine c++ and c#. I mean, if I create a DirectX device using c++, could I draw it in a c# window. I'm not so confortable with c# and I 'd like to develop a 3D modeler based on c++ with an c# interface (I suppose the easiest way to create fancy user interface). Thanks for your help You can develelop you code in C++ and then expose it to C# as library using managed C++. Otherwise you can make you C++ code to be ActiveX control and use it from C# as such, yet another way is to make C++ dll with exported functions and then call the funtions from C# using dllimport attribute (just search the internet for examples and you will find thouthands of them). ...Show All

• Visual Studio 2008 (Pre-release) MenuItem DataTrigger error trying to change Header

  Hello, I am trying to toggle the header text of a menu item based on bound data, but the following code will not compile due to the error below.

• Visual C# remove element from an array of string

  hi everybody, I have an array of string myArray[0] = "Hello World"; myArray[1] = "This is a sample code"; myArray[2] = "Delete me"; how do I delete element 2 or I need to copy everything but element 2 I don't know what would be best in this case and if I have a lot of informations. thanks Arrays do not have built-in deletion capabilities. Use an ArrayList of strings (or List<string> in .NET 2.0), and then call the RemoveAt method to remove the elements you have to. If you are going to be doing a lot of deleting in a large list, though, consider using a linked list . ...Show All

• .NET Development Application.DoEvents in .NET 3.0 ?

  Hello, Is there an equivalent of Application.DoEvents in .NET 3.0 If so, what is it Thank you Tom I don't think there's any such thing in WPF. DoEvents was used basically to process the message queue, but since WPF no longer has the thread affinity of Windows Forms, I'd imagine they've done away with the message queue. ...Show All

• Smart Device Development C# Device Applications Serial Port

  HelloI am trying to link a Windows application with a device application. Windows divice applications have a serial control so I though I could link them together using a virtual comm port. I created a port object in the device application and sent data to COM1. This data did not appear in the port monitoring program that I am using.This leads me to think that this idea is not going to work.If I have a PDA actively syncd' to visual studio is there a way I can send data to the application running on the PDA Thanks This port is not specific to PDA's but there are a lot of hardware decices which can be connected to your PC or PDA on some virtual COM port. Once its found on some COM port that can be interfaced ...Show All

• Visual Studio Team System Open Solution under VS 2003 is very slow

  We just migrated our source code from VSS to TFS. Our solution contains about 70 projects. Opening the solution with VS 2003 now takes several minutes which is much more time than it did take under VSS source control. It takes about 7 seconds for each project to appear in the solution explorer. We are using TFS MSSCCI Provider Version 1.1.  Is there a workaround for this   Please send us the webmethod trace log first to tfmsscci@microsoft.com . Please try to zip or winrar it. That usually reduce the text file size to less than 10%. Thanks, Pei ...Show All

• SQL Server Executing a View timesout through Open View

  Hello All, I have created a view that will potentially return a huge number of records around 500,000 rows. When i execute this view by clicking Open View from the SQL Management studio i get the following error SQL Execution error Error Source: .Net SqlClient Data Provider Error Message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding However the query executes when paste the generated query of the view in the query designer window. It returns the 500,000 rows. I am wondering if there is some option that i will have to configure to return a large size result set in view designer.

• Visual Studio Team System Setting "CreatedBy" field programatically

  Hello, I'm writting an application for migrating items from our old defect tracking system (PVCS Tracker) to TFS Work Item. I'm using the Microsoft.TeamFoundation.WorkItemTracking.Client namespace for that. I have an issue with the WorkItem.CreatedBy property since it is read-only. Indeed, we want to migrate the "author" value to this property. How could I solve this issue Thanks I understand that this is possible by coding directly to the work item tracking web service, but that's a complicated undertaking. Putting the info to another field or in the comments is the simplest solution. ...Show All

• Software Development for Windows Vista The UAC Nightmare

  I'm beginning to reach the conclusion that the current implementation of the UAC in Vista is, IMO, a nightmare that creates more problems than it solves. If Microsoft wants developers - and users - to embrace the UAC (instead of just turning it off altogether) then it better come forward with a LOT MORE information and support than it is currently providing! If it doesn't, I will begin to suspect Microsoft only added the UAC so it can tell Windows users 'well, we added the option to secure Windows - you're the ones turning it off' and therefore wash its corporate hands. I would really hate to see this happening. To name just a few of the problems the UAC brings to us developers: 1 - Applications that require Admin privileges are bloc ...Show All

• SQL Server TIFF render quality problem

  The quality of rendering for reports in TIFF format is really nasty. Fonts are horrible. Is there anything we can do to improve the quality when rendered in TIFF format We had to change rendering type from PDF to TIFF because Acrobat Reader could not display the reports we were generating (apparently because of images). Thanks. Glenn. No. We get "A drawing error occurred" when attempting to view the PDFs. Searching the net has led me to believe that Acrobat cannot handle some images very well, especially if they have transparency. The images we embed in the report are not under our control, they are generated by MapPoint and another third party company. We sometimes have 10-15 ...Show All
