View 3 RepliesI have 2 tables that are related,both have identity columns for primary keys and i am using a vb form to insert data into them,My problem is that i cannot get the child table to get the primary key of the parent table and use this as its foreign key in my database.the data is inserted fine though no foreign key constraint is made.I am wondering if a trigger will do it and if so how. All my inserting of data is done in vb.The user wont insert any keys. all these are identity columns that are auto generated. If a trigger is my way out please illustrate with an example.

In the screenshot, you can see where the BackColor is set for each item added to the ListView on the right. How can I fill the white space between the columns as well? I'm assuming the column width is the highlighted portion plus the white space. I thought setting the BackColor would fill this whole portion so that there essentially would be no white space at all showing anywhere in the listview (except maybe at the bottom). Is there a Property I need to set to do this? the listview has 1 column and it's autoresize property is set to CellContent.

With a Decimal, I use:
document.Air1 = CDec(IIf(Decimal.TryParse(Air1TextBox.Text, Nothing), Air1TextBox.Text, "0")) to fill the column with there is no value.
I would like to do something similar when the date is blank (preferably with NULL or just plain blank):
document.TestDate1 = CDate(IIf(Date.TryParse(TestDate1TextBox.Text, Nothing), TestDate1TextBox.Text, " - - ")) - of course, this throws an exception.
The table Data Type is date.
