  Hi, If anybody experienced the problem: after installation of February WinFX CTP library System.ServiceModel disappeared from VS project reference list. November CTP worked Ok. Any help would be very appreciated. Dmitry Okonov I solved this problem by editing my machine.config file. It was still pointing to the "2.0.0.0" reference of system.servicemodel. I edited all the "2.0.0.0" references to system.servicemodel to point to "3.0.0.0" and it started working. Thanks, Chuck ...Show All

• .NET Development Updating database

  i have a problem to update my database. in my update button i have the following code: dataset.AcceptChanges() Adapter.Update(dataset.table) i've tried other things like: adapter.update(dataset) swopped the two lines around... it saves the data on the current form, but when i close the form and reopen it, the data never changed in my database. i think the changes get saved in my dataset, but not in my database... but aren't sure... Thanx Kurt, The DataSet that you copied from probably needed an .EndEdit() somewhere. I'm sure the Copy itself does nothing to the row state of the rows it is copying. I've ...Show All

• Visual Basic VB 2005 Window Stay On Top?

  I was trying to get my form (the main form Form1) to stay on top all other windows windows(such like the Windows Task Manager) but with no luck. I tried Google and came up with several approaches: One used the SetWindowPos API call but that generated some insanley cryptic message that the call '...unbalanced the stack...'. I also tried setting the form's TopMost property to true, but that only made the main form stay on top the other forms, in the the same project, not all other windows at runtime. So far I have nothing so if anyone had this problem before please say what I'm doing wrong (or not doing at all). Thanks in advanc ...Show All
