• Software Development for Windows Vista How to unit test custom activities

  Hi all, I would like to create some custom activities but I'm not too sure about what approach to use to create unit tests for them (I normally use NUnit). Do you guys have any good suggestion Thanks! Hi Claudio, In order to thoroughly test an activity, here are some key items you want to cover: -Validation - property values, parent/child relationships, etc. -Runtime - normal execution scenarios, cancellation scenarios, faulting scenarios, compensation scenarios, dynamic update, load/unload (workflow persistence), behavior inside child contexts (your activity as a child of a WhileActivity for instance) ...Show All

• SQL Server MySQL to SQL Server migration

  Hi, I would liked to know the SQL Server equivalent for the below MySQL query : SELECT a.col1, a.col2, max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1 Thanks, Smitha You can do it the same way except you can't just show a.col2. You use groupby, so it must belong to some logical output. You can do it like: SELECT a.col1, max(a.col2), --or other functions... max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1 OR SELECT a.col1, a.col2, max(a.col1) FROM test a, test1 b WHERE a.col2 = b.col2 GROUP BY a.col1, a.col2 Hope it helps ...Show All

• Visual Basic DataAdapter Select Statement

  To all I'm VS2003, when I try and create a dataadapter with more than 100 fields (either through drag-n-drop or manually) I received "There were errors configuring the dataadapter". Since the table is in SQL 2000, I tried using: "Select * From inmast" which returns 143 columns and all rows from the table I even tried importing the table in MS Access 2003 with the same results. If I reduce the # of fields to 100 or below the dataadapter will work as normal Help David Davis Hi, Thanks for keeping us posted. So that's a limitation. Haven't even seen it in the documentation...

• SQL Server Caching problem?

  If I create a view and then a mining structure run it everything works fine BUT if I then alter the view (e.g change a filter setting in a named query) or the actual contents of the database, the OLD contents persist. Using the view refresh says there are no changes (which is correct as I don't change any column names etc.). If I remove Keep Training Cases, this fixes it, but for Time Series, it then gives an error, so you have to go back and re-select it... is there a direct option to clear caches The dependency settings aren't sensitive to non-destructive changes in the DSV. You can simply do a Proce ...Show All
