View 1 RepliesEditing Databases After They've Been Added To The Project -VB 2008
May 12, 2010Not sure if I'm posting this in the right area, but here goes anyway. I've been working with sql databases for practice, but can't seem to get around one thing; after I add it as a data source, I can't go back and add tables.
I start off by going through the project, then add item, choose the service-based database, and go from there. I add the tables, then go in and add it as a data source.
After I've added it as a data source, I can go back into the .mdf form and add lines and edit properties, but it wont update in the data sources. So, I can't add it to the form.
VS 2008 - Editing Textbox Property From Thread?

I've already tried with the CheckForIllegalCrossThreadCalls to False on the onLoad event of the textbox's form but it doesn't seems to work because everytime the thread executes the lines that should change the textbox value nothing happens at all (not even a warning). I really don't want to use that "safe cross threading" with delegates and stuff because it's too much trouble for me, I don't know how to use it and I just have one thread on my project and it's the only control that is accessing those textboxes.
