• Visual Studio Team System Migrating TFS workspace from TFS Server A to TFS Server B, is this possible ??

  Hi, I’m trying to migrate a complete TFS Workspace hosting in a small TFS Server to a bigger environment. I can unbind the complete solution and add the solution to the new TFS Server, but I want to keep the history, build tests, etc. Is there any way to do this Thanks from Spain Bruno Capuano Blog: http://www.elbruno.com Unfortunately, we don't have a partial migration tool. You have to restore the entire database on top of the "bigger" server, which would erase anything it already has.  There's work being done to enable migration on the Team Project level, but I'm not sure of the ETA. ...Show All

• Visual Studio MFC debug information absent with symbol server use

• SQL Server Convert UTC time to local time

  Hello, I am new with the reporting services. I am creating a report and I need to display date/time on the report. But the servers stores those date/time in UTC. How can I convert them to the local time in my report.   Thanks for your help.     You need to use System.TimeZone.ToLocalTime(UTCTime). See http://msdn2.microsoft.com/en-us/library/system.timezone.tolocaltime.aspx . You should be able to use TimeZone.CurrentTimeZone if you want to convert using the server time zone. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Preventing memory leaks

  Hello, I am trying to make my project clean and so I am looking for memory leaks reported by DirectX debug driver. The problem has two parts: 1) if I set a "Break on AllocId" in DX configuration with Id obtained from previous program run where DX reported memory leak, project is stopped on absolutely unrelated piece of code - is it possible that it takes some time for DX to stop it when it catches a problem how can i find the exact location could this be because of I am running it multithreaded 2) I discovered that even such calls as SetStreamSource, SetIndices, etc. throw a memory leak if they are not "unloaded" by th ...Show All

• .NET Development Very slow debugging

  I have the 2.0 framework on one computer and haven't tested it anywhere else, but I'm experiencing very slow debugging. I have a Windows Form app with about 60 classes/forms. Sometimes after making a few character change in code it takes 30 seconds before I can continue in the editor. Opening a form with a lot of controls on it can take almost a minute. The hard-drive runs almost continuously during these "wait" times. The computer is a 3.2GH P4 with has 2GB RAM and 700GB (fast) disk. I know that the 2.0 editor does a lot more work than the 1.1 editor did, but the wasted time during coding is very PAINFUL - anyone else having these ...Show All

• Software Development for Windows Vista Can the state-transition workflow designer control be extended (using code) to support "swim lanes"?

  http://office.microsoft.com/assistance/hfws.aspx AssetID=HP815503021033  is an example of an UML 2.0 Activity diagram ...but don't get caught up in all the details you see in the diagram. However, do note that the activities are aligned into 2 role-based groups (vertical columns): Program Administration and Test Administration.  These vertical columns are often referred to as "swim lanes". Is it possible, in a custom WinForms designer host application, to extend the state -transition workflow designer control to create and display swim lanes In this case,  it would be a new Root Activity derived from StateTran ...Show All

• Visual Studio Express Editions How to change key assignments

  Can anyone help me wrestle with key assigments in Visual Studio Express. Tools | Options | Environment |Keyboard must be the worst designed dialog to change key assignments I have ever seen, that is, if it is actually designed to do this - I can't even tell. I simply want to make it so that Ctrl-D deletes a line (not cuts it). Are there any tutorials on how to use this dialog anywhere There is no help for that page. I'm sorry about your frustration, but thank you for the feedback. The easiest way to assign a shortcut key is to search for a command, like type "Edit" which will search all keyboard shortc ...Show All

• Visual Basic Searching via a textbox string

  Hi... I'm just jumping in to VS2005, and have tried to create a simple database search that will return all the items that are similar (begins or like ) text in a 3 column database table. The form has an input textbox, and a datagrid, similar to the output of an ASPRUNNER-PRO page...only I don't want a web page, I want to do this on a form. Everything IO've seen and read pertains to bound data to text boxes, whic is the opposite of what I am trying. I want to search and display the results of my matches. For instance...

• Visual Studio Addin (automation) Form lost input focus forever

  If it is not the right place to post any addin (automation) posts, I apologize. I didn't find any addin related groups. I am building an addin which shows a Form using ShowDialog(), the form provides functionalities to: * add/remove ProjectItems from VS.NET Solution Explorer (under Source Control) * select/unselect/add/remove UIHierarchyItem Because the form is shown as a modal Form, normally it is the ForgroundWindow and has the input focus. But when it is adding item to source controlled Project, SCC Provider launches it's own dialog, and after that dialog dispeared, things goes bad: the input focus goes to VS.NET' ...Show All
