• Visual Studio Team System WebTest showing no errors, but results missing DB changes

  I've just been introduced to the WebTest features of VS2005 to crack a problem we've been having with its use on our company's ecommerce store. It seems that recording a complete purchase life-cycle, from entry page to check-out summary, everything appears all green when I re-play the recording. But when I check the database, only the recording session actually gets recorded in the database. None of the play-backs actually result in an insert of data into our database. Reading through the technotes I have found so far, I see a lot of suggestions for when you get errors on the play-back, referring to client-side JavaScript redirects, dynamic data and various things like that. But in this case, the pages coming back are different than ...Show All

• Visual C# iterating through a dataset

  Hello all.  I want to iterate through a dataset and pretty much have the logic down.  I'm using a foreach loop like so: foreach(DataRow row in ds.Tables[0].Rows) { //logic here } The table in the dataset has two columns.  The first column is a count (int) and the second column contains a timestamp (DateTime).  What I want to do is sum up all the counts in increments of 5 minutes.  The data provides me with increments of 1 minute timestamps, sometimes multiple records for the same timestamp.  In other words, my data would look something like this: timestamp    count 1:53             1000 1:54    &nb ...Show All

• .NET Development Internal vs. Public

  Sorry if this is simplistic, but is it a viable design choice to restrict visibility of as many type members as possible in a Windows application exe to internal, rather than public This client will necessarily never be consumed by any other class or application. It also suppresses various VS warnings about uncommented members, which are irrelevant anyway in many cases. Thoughts, comments Oh, okay, thanks. I just managed to get one of those by deleting the designer generated comments by hand. Never thought to turn on XML documentation for .exe builds... ...Show All

• Visual Basic DataGridView - Using a Custom Property of a Typed Data Row? For Foreign Key Lookup

  I have been searching for a solution to do a foreign key lookup for a datarow in a databound dataset.
