• Visual Studio Team System Generate the value of a field in a workitem

  Hi all, I have a question on how I can generate the value of a field in a workitem. This value should contains a number or id to reference the project, the creation date of the project and some another indications. The value of the field must be filled in when creating a new WorkItem with for example "AB[Project Number][Date in own format]01ZZ". This value is then used to reference the workitem in our administration. We use this number already in a internally developed solution to create and track items, so this could make the migration from the internally developed solution to Team Foundation Server a lot easier. Users do not have to swit ...Show All

• SQL Server Web App Failover problem

  Hi, I have successfully set-up a DB mirroring. When the pricipal goes down, the mirror picksup and the other way around too. So the mirroring part is working great. However, when I use my web applicaiton (dot net 2.0), it is not able to connect to Mirror server . I get the following error: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections.

• Visual Studio Express Editions Updating a form from a serialport component.

  Having been a Borland C++ chappie over the years, I've basically created my own RS232 object and dumped it in a seperate Thread, which then directly calls a static function in the forms thread, which then updates the the main forms bit & bobs. Problems occured when the RS232 object starts pummeling data into the function before it is cleared etc, and then all goes bonkers! I obviously had broken the cardinal rule "Thou shalt not interact with a control's properties from a thread other than the one that created the control." In comes VC++ Express and a serialPort object, written by someone who knows what they are doing. ...Show All

• Windows Forms Exception in Graphics.DrawPath in special circumstances.

  Hi, I'm getting an Exception in certain circumstances when drawing a GraphicsPath. But I've also managed getting the exception with Graphics.DrawPolygon. Initially drawing is ok, but when resizing horizontally at some point an exception will pop up (inner exception is a NullRefException I think). Very obscure! The style flags have something to do with it, because when I don't use them everything looks ok. Here's the program that will cause the problem. using System; using System.Drawing; using System.Drawing.Drawing2D; using System.Windows.Forms; namespace DrawPath {     /// <summary>     // ...Show All

• SQL Server BUG? Extracting Data Stored in Multiple Languages

  Hi, I have an access database that is storing text in english and chinese characters. I am importing the data using SSIS and it is putting a 'square' character in place of all the chinese characters. Can I associate multiple code pages to a control If this is not possible, I would just like to Extract the data and Load it into a table, and i will just handle the errors and write the key fields to an error log. The problem is that the error handler is not redirecting the row. It just simply fails. I have changed all the error actions to Redirect Row too. I currently have a script checking if the 'square' character exists but i feel this sh ...Show All
