• Visual Studio Team System tftp query and workitem return "Unable to determine the source control server"

  We have an RTM Team Foundation Server setup and I downloaded the latest PowerToys. C:\Program Files\Microsoft Team Foundation Server Power Toys>filever /v TFPT.exe --a-- W32i APP - 8.1.0.0 shp 172,032 08-30-2006 tfpt.exe But when I run tfpt workitem or tfpt query I get an error.

• Software Development for Windows Vista Workflow Properties???

  I used DynamicPropertiesActivityLibrary created by ghenap http://blogs.msdn.com/ghenap/default.aspx I have some questions: The properties created are not detectable in the rule set editor. I want to validate and change its value depending on other values by using policy activity (as in quantity and discount sample)… I want to create my own custom activity that let the user to set the properties created by DyamicPropertiesActivityLibrary. For example, the property grid for this activity will have two fields; one is dropdown list with all properties created in the workflow. The other will hold the new value for this property.. Can I do this If yes how, and if there is any sample .. My las ...Show All

• Smart Device Development updating a datagrid

  I am using bound text boxes to update datagrid rows. When I try to update the SQL mobile database with Me.TableAdapter.Update(Me.DataSet.table) I get an error that states "Unexpected Error" and "Upadate requires a valid updatecommand when passed datarow collection with modified rows." Is there another statement that is needed Thank you. For clarification, if a row is added, the data base updates with out a problem. If I alter an existing row, then I am not able to save it. I believe designers would add CommandBuilder automatically unless you don't have a primary key. In that case update/insert commands can not be automatically generated. Primary key is a must have in any database, so please add it, ...Show All

• Visual Studio Express Editions OpenMP support

  I would like to use OpenMP in my program, but it appears that vcomp.lib is missing (and its debug version). Now I am not sure is Express supports OpenMP, but since the compiler switch is in there, it would seem so. So can anyone suggest what is going on Installation problem, maybe Or simply options are selectable in the project which should not be available Thanks! -x OpenMP is not supported in the express editions, see the following for a list of supported features: http://msdn2.microsoft.com/en-us/library/hs24szh9(VS.80).aspx ...Show All

• SQL Server Problems with merging raw files opened as variables

  I have a group of parallel dataflow tasks that produce raw file outputs that I then want to merge together in a subsequent task. I use variable names for the raw file outputs because I want to the path to the files to be easy to configure for different deployment environments. Therefore, I've got a package scoped variable called pkgRawFileFolder and in each of my parallel tasks my raw file destination is derived from another variable scoped at the task level, called tskRawFileOutput which is evaluated as an expression equal to [User::pkgRawFileFolder]+"/RawFile_1" or similar (the name of the rawfile isn't important as long as each parallel task uses a different name). In the container task that performs the merge, I want a Foreac ...Show All

• .NET Development Is it possible to calculate a column value in a DataTable using managed code in .NET 2.0?

  Hi, I have a requirement to populate an asp.net 2.0 GridView control with data, with some columns directly retrieved from a SQL Server 2005 stored procedure and others calculated from those columns using .NET method calls. I thought I could achieve this by using an ObjectDataSource calling a GetData method in a DataSet created using the DataSet Designer, then hooking into an event where I could calculate the values for the required extra columns of data, so that these would appear in the GridView. However, I can't find an appropriate event to hook into to do this. Does anyone know how to achieve the effect I require Setting DataColumn.Expression looks like it ought to do this, but that does not allow anything except SQL express ...Show All

• Visual Basic How to Rotate Text in RTF

  Hi Folks, Any RTF experts out there I want to insert a text object that is rotated like what you can do in Powerpoint's text box or Word's Word Art. Unfortunately, when either is saved in RTF, the text content is lost in the raw code, so I cannot do a search and replace on the rotated text. Word only saves the text content if the text box is used with the alignment changed to vertical. Is there any way to create rotated text that is visible in the RTF code I am prepared to insert all the required positioning code myself, if I only knew what was required. Any ideas would be greatly appreciated. Hi Again Folks, DMan1 seems to understand my problem. The rotated text is embedded into t ...Show All

• Visual Studio Team System Code Analysis for Websites

  Pardon me if this question has been asked before, but I did some searching and couldn't find the answer. The Code Analysis settings for a website (Website | Code Analysis Configuration) are stored only locally on the developer's PC, correct I guess this makes sense, as there's no Web Project solution file as in VS2003.. so there's really no file-based place for that setting to go. Does this mean each developer on the team has to manually enable Code Analysis for the website as well We have a project team complaining about this.. Thanks, Jeff Yes this is correct. This is a limitation of the website 'project-less' project. The new (free) aftermarket Web A ...Show All

• SQL Server Query timeout

  I need to figure out if my query is timing out due to row lock contention. The SqlException trapped in my client C# application contains Error Number 1205 but sometimes it contains -2. I guess the SqlCommand timeout and the server timeout are the two possibilities. Is there a definitive way to find out that the SqlException was thrown due to one of these two reasons Because if it's some other reason, I want to excute a different logic. Thanks, Madhav 1205 indicates transaction was aborted due to deadlock.

• SQL Server Performance degradation after replication rolled out

  Hi all. Any assistance would be greatly appreciated. We recently created transactional replication to hopefully improve performance issues we were expereincing. The replication is between 2 SQL Servers (2000), and since we have introduced the replication, the performance has degraded considerably. I will try and explain the scenario. We have a primary db that our internal users use and we also have the newly replicated db that our website and another application use. The users are complaining that the website and the internal application is extremely slow and I was just wondering if it is possible to do an Index Tuning on both the primary db and replicated db based on trace files so as to create new indexes or would this have a ...Show All

• SQL Server Peer-to-Peer Replication (Programmatic Control and Setup)

  I have reviewed the BOL documentation on how to configure Peer-to-Peer replication via T-SQL and how to use the Replication Wizard to implement replication. What I would like to find out is how do I configure the peer-to-peer replication process to use an existing column on a table that contains a GUID instead of creating an extra column with a uniqueidentifier GUID value. When you use the Wizard each table article has this extra column added to it. I don't seem to be able to find it in the books-on-line. Can some one point me to the correct article or BOL page. Thank you. ...cordell... I do not think that P2P replication adds a uniqueidentifier column to a published table. Transactional queue ...Show All
