• Visual Studio Team System Mark an iteration complete?

  This seems like a really simple task, but I can't see how to mark an iteration complete. I don't want to delete it of course, and loose the project data to that iteration, but I don't want it to be an option for new work items. So how do I mark an iteration complete so it can't get new work items, yet remains in the reports I'm not sure I like the term "inactive" - it has a different meaning than "complete". "Closed" would be another option, since this would be the same meaning as a closed work item. The why is pretty obvious - if you are doing the agile thing correctly, with 1-2week iterations, then after a year you'll have over 25 iterations in the work item drop down! This ...Show All

• Windows Forms Find DataRow with matching data in a DataTable

  Is there som efficient (other than looping through the whole table for each new datarow) way of finding out if a datarow with the same data is present in a datatable The rows are different but the data in the datarows are the same. I usually sort the datatable's defaultview by all the columns (sort = "col1,col2,col3, etc") and check and see if the next record is a duplicate. Here is a link to an example . ...Show All

• SQL Server Agglomerative clustering?

  I promise this is the last question I'll ask today. Suppose you have some market basket data i.e. baskets that are collections of products. The retailer assigns each product to a category. Let's say there are quite a small number of categories: 20-30. As it happens, I have such a dataset. Now suppose you want to test the hypothesis that there are clusters of customers ("segments") who can be identified by the tendency to buy products from within a group of categories. You want a smaller number of segments: say 5-10. The desired end point is a set of segments, where each segment is associated with a set of categories and each category is associated with exactly one segment. You can then assign customers to segments according ...Show All

• Visual Studio Custom tool window like DSL Details..

  Hi all, I have defined my first little language with the very impressive DSL Tools. When I now work with the application I miss a custom window to handle the (very specific) configuration of some of my model classes. What I need is a tool like the DSL Details tool window so I want to ask if someone has already builds a similar think. Seems like I have two (write an Add-in or a Package) or more options to solve my requirements but I’m not sure what is the best way to do this. Today I’m not very familiar with writing any kind of IDE Extension but after looking in the documentation it looks not really hard. But the first big problem is: How can I call a command from the DSL Designer View to the Add-in and vice versa. ...Show All

• SQL Server Custom Task: How to access/modify the Expression Collection of a package

  Hi, I created a Custom Task which it has a Property called ConfigFilePath. I'm overriding the Validate() method from Task. I want to throw an error if my property ConfigFilePath is empty and if the expression for this property is empty. So far, I can check if the property is empty but I don't see how I can access the Expressions Collection of my Custom Task. Any thoughts I'd appreciate your help. Hi Michael, Let me see if I understood you. You're saying that I cannot have access to the Expression collection of a task All I want to do is for example, if you have a Script Task and there is a syntax error in the Script Task, after you close the Visual Studio GUI and return to the BI GUI you see that the Script Task has a red cross.

• Visual FoxPro Parameters in a VFP method

  Hi All, I want to use PARAMETERS in a VFP method. How can I achieve this. Example: In a method called MyMethod FUNCTION getperiod(ldDateIn, lnPeriodIdIn) SELECT myTable SELECT periodid FROM myTable WHERE DateIn = ldDateIn AND PeriodIdIn = lnPeriodIdIn INTO CURSOR myCursor RETURN PeriodID (Which in this case is a numeric value) Thanks for any help or insight.

• Software Development for Windows Vista Application crashes when attached to App Verifier 3.3

  Hi, Our application crashes when it is attached to App Verifier 3.3. The only test box checked is LuaPriv. After some testing, we discovered our app crashes when it calls the "OleLoadPictureFile" function. When App Verifier is not attached, the app does not crash. I tried running the app as administrator and is still crashes. We also tried feeding different bitmaps into the function and it did not help. Any ideas or suggestions After numerous searches, I have not found any issues regarding App Verifier and OleLoadPictureFile. I also launched Standard User Analyzer which automatically launched the app and invoked App Verifier. Still crashed. Thanks in advance. Wes Can you post the AppVerifier L ...Show All

• Visual C# Aligning @ Equals

  Ok,  i'll admit when it comes to formatting code, but is there a way to stop VS.NET 2005 from removing the extra spaces i put in to align my code When i write: some.thing       = 1; some.other_thing = 2;  I end up with: some.thing = 1; some.other_thing = 2; Surprisingly annoying The formatting options in VS 2005 do not directly support this kind of alignment, but I can offer you a workaround that should prevent VS from removing the extra spaces.

• .NET Development error: stored proc expects param @xxxxx not supplied
