• Visual Studio Team System COOKBOOK for TFS server installation - please

  Hi I've been trying to install TFS server beta 3 refresh for more than a week - it feels more like a month... Has anyone written down the complete cookbook for a successful installation If so pls. forward that, because this seems very difficult to do correctly. The very best would be a cookbook that starts off with a 'clean' virtual server, and leads me by the hand through this labyrint of strange options and issues. Thanx jcjj pls. MS do supply some diagnostic tool to pinpoint faults in the setup.... JCJJ I'm sorry to hear that you're having trouble getting things set up. There are indeed a lot of options to get configured correctly ...Show All

• Visual Studio Team System Graphs in Team Edition for Software Testers

  Hi I have created a load test and I ran it for 100 Vusers and for a duration of 10 minutes. I have added several counters to the test. Now, in the graph that I see, in the results; I could not identify what does Y axis refer to. Can anybody please explain me what does the Y axis refer to X-axis is of course showing the time in seconds. Does the Y-axis value depend on the counter we select or is it constant for any type of counter For ex: if we select pages/second counter, I assumed that the value for Y axis indicates the number of pages received per second. Similarly when I selected the average response time counter, I assumed that at ...Show All

• .NET Development Web Service state question

• .NET Development how web service client will know about user defined data type?

  If a web method returns user defined object how web service client will know about user defined data type Usually proxy wizard generates class skeletons used for webservices. And webservices transfer only data. Thus it doesn't matter to client where the original class comes from as long as the class on the client side can be used for deserialization (having same properties, etc.) ...Show All

• Windows Forms DataGridView SortOrder property not same type as parameter to DGV Sort method

  The Sort method of the DataGridView has the following signature: Dim dataGridViewColumn As DataGridViewColumn Dim direction As System.ComponentModel.ListSortDirection Dim dataGridView1 As DataGridView dataGridView1.Sort(dataGridViewColumn, direction)   The SortOrder property of the DataGridView is of type System.Windows.Forms.SortOrder. The question I have is why are they not the same   These enumerations appear to have different underlying values.  Thus, you can't simply assign one to the other.  If you want to track the current sort order of a DGV you have to convert between the two types.  Is there some r ...Show All

• Visual Studio Team System Version Control Best Practices?

  Can somebody please provide some best practices in the use of Team System Version Control Especially in the area of mulitple builds, etc. Here is an example: We have a single code-base with 2 different clients.  We do daily builds for our internal QA folk.  Usually on a bi-weekly basis we do a build out to the production server as well.  A couple of days later we may do another build that is put out to the production server for the 2nd client.  How can we best manage these multiple versions If we do a production build on Monday, then do 3 more daily builds internally, then realize we need to "hotfix" something on the pro ...Show All
