• Visual Studio Installing VS2005 web service on system with TFS/WSS

• Visual Studio Express Editions odd textbox behaviour - bug?

  I have a controls on a form bound to a binding source.  The first control (textbox) is my auto-number field and is read only.  I also have a function that clears all the controls (textboxes, combo's, and date pickers) on the form when a user deletes a record or clicks the "add new" button.  After this occurs, the focus is put (not by me) on the auto-number field textbox.  From that point on I am not able to get out of the textbox unless I stop the debugger and restart the program.  Its like it is stuck in the textbox.  I have tried taking the tabstop away and as long as I don't click in the textbox I am ok. ...Show All

• Software Development for Windows Vista Workflow published as a WebService + persistence required in Beta2

  Hi all, In moving over my workflows from beta1 to beta2, I did the publish as a webservice and all worked fine. If I have a very simple 'sample' wf as a webservice (i.e. 2 shapes, WS receive + WS Response) it works fine (without persistence) However when I start to build my more complex ones - the WebService complains that there's no persistence service added..... Question: What determines whether I need a persistence service or not added to a WS Is it based on datatype e.g. XmlDocument I ideally dont want any persistence here (it's being looked after by BizTalk2006) Many thanks for any light shed -- further to add - ...Show All
