Hello,
Windows forms & database
What are the considerations when choosing how to display reference
information from the calling form? What is recommended?
Table1 is the parent of Table2.
Form1 allows data entry into Table1.
Form2 allows data entry into Table2.
Form1 (the parent) opens Form2 (the child)
I need to display six fields from the parent table or form.
I see my options as...
1.) Populate the child form from a stored procedure that uses a SQL
Server View that contains a relationship between the two tables. Supply
the PK of the parent as the parameter for the stored procedure used to
populate the child.
2.) Open the child form as ShowDialog from Form1 and hide rather than
close Form1. Open Form2 by calling a simple stored procedure that
reference only the child table supply the PK of the parent as the
parameter to filter the child table. Get the six reference fields
through the use of public fields or public properties.
There are other options but I believe the two above are better. Which
is the best and what are the considerations in choosing.
I favor #1 but have not worked with views and have reservations about
how to proceed.
Thank you,

Keep in mind, if you do a join then then the view will end up in one
DataTable, you'll also have redundant information since each child row also
contains the parent row data.

If you are planning on closing Form1, then you could copy the parent DataRow
while passing it to Form2 before showing it. Then you fill the child
DataTable by a simple stored procedure.
Or just could pass Form1's DataSet to Form2 if it contains a parent
DataTable with one DataRow and an empty child DataTable.

I can see that you are using .Net and VB..
1- you can pass the Datarow from Form1 to Form2 and so on if u need to pass
data for more forms..
2- I better recommend you use Microsoft User Interface Process (UIP)
Application Block. http://msdn.microsoft.com/library/en...html/uipab.asp

You'd think it'd be easier to find the answer to this question.
Did a search, and all I can find is people asking why something's not
working and people replying it's because register_globals is off.
I found one person said: "The change is for the better since
register_global turned to on had some grim security implications." but
no mentioning of what those are!
