View 13 RepliesIm pretty use to doing loops (although still relative new to vb) in my code however am having difficulty setting up one that picks up an entry in one data table and then sums a field in another where records have matching criteria. Example:
[Code]...
What i am trying to do is set up a datagridview on a form that shows the summary data. The time is controlled on the form by a trackbar (output to textbox) and I started setting up a loop using (For/Next) to isolate firstly the matching entries in field 3 (time). This works fine. I then used compute to sum the the field 2. However what i want to do is to loop through table 2 and where entries match i.e. where Field 1 in table 2="A" sum matching entries in table 1 where the DateTime matches.

I'm doing an application for a school to help them keep track of student attendance and because I'm rather new to VB 2008 .NET I'm sure I'm missing something simple.see the screen shot and attached sample application showing the problem I am having.
The screen shot shows 3 open forms. I'm not able to get the value from the 3rd open form into the Student ID textbox of the 2nd form even though my messagebox shows a value is really in there.The attached application has 3 forms similar to the production application I'm writing which also includes 3 forms.
