Visual basic validating fields

6854933580_2c8b688306_z

Couple of comments: I'm more concerned about what the user hasn't done than what they have done so using the validating event does me no good since they haven't touched the field. Position = i 1 Validate Data = False Offending Control = Me.

In addition, in certain cases I'm looking for combinations of values, i.e., if a field has a certain value then other fields should be entered or contain certain values. Cancel Edit Method Sub Accept Or Reject(By Val row As Data Row) ' Use a function to validate the row's values. Cancel Edit() End If End Sub Private Function Validate Row(By Val row As Data Row) As Boolean Dim is Valid As Boolean ' Insert code to validate the row values. Validate Row = is Valid End Function Thanks...i see the confusion....while the form is parent/child its not the child records i'm concerned about, it's the parent. Customer POText Box Exit For End If If r("Customer ID") = 0 Then Msg = "Customer cannot be blank." Offending Control = Customer Me. Position = i 1 Validate Data = False Offending Control = Employee Exit For End If If r("Employee ID") = 0 Then Msg = "Employee cannot be blank." Offending Control = Employee Me. Position = i 1 Validate Data = False Offending Control = Terms Exit For End If If r("Terms") = "Credit Card" Then If Is DBNull(r("CCName")) Or Is DBNull(r("CCNumber")) _ Or Is DBNull(r("CCDate")) Or Is DBNull(r("CCAddress")) _ Or Is DBNull(r("CCZIP")) Or Is DBNull(r("CCSec Code")) Then Msg = "Credit info required for ""Credit Card"" terms" Me.

Question here is How do I reposition the form at the offending record? To String() Next ' Get the Data Set for the table, and test it for errors. Data Set Test For Errors(data Set) End Sub Private Sub Test For Errors(By Val data Set As Data Set) ' Test for errors.

Hi as stated in my preliminary post , there are really a lot of solutions to this senario. Row Error Property you can check and fetch the row(s) that contains an error before doing a update to the datasource and show the rows that contains errors that has to be corrected by the user before the final save.

Visual Basic, VS2005 How do I validate the data in a table before updating to the database.

Here's the situation: Using a binding navigator and strongly type datasets, with a form that will load from 1 to N records, a user is able to make changes on any record by scrolling with the binding navigator.

For example, if the order is on a credit card, then I want the credit card info captured, otherwise, I want those fields empty. ' If the function returns true, end the edit; ' otherwise cancel it. Using what you've said so far, here's what i came up with. Sales Order Binding Source A positive customer journey is important in attracting and retaining business.

It seems to me that the only way to accomplish that is to check the contents of the record when the user says they're finished (presses save, next or previous on the binding navigator.) It seems to me that i can A. It seems to do what i want, returning to the offending order. Focus() End If End If End Sub Private Function Validate Data(By Ref Msg As String, _ By Ref Offending Control As Control) As Boolean Dim r As Sales Orders. To improve this experience, you can use Google Maps APIs to increase checkout conversions, boost user engagement, and optimize order fulfillment.

Some common data validation requirements are outlined below.At the very least I need references to documentation that is demonstrating practical examples.(Not the tripe that passes for coding examples in some of the MS documentation.) Hi Well there are serveral approaches to what you are asking , also you are asking a lot of questions (not just one) here is a link (hard coding) to moving forward, prevous..(For that matter, does the move forward or prevous click even happen before or after the record has moved?) Despite hours of searching, I've been unable to locate any decent documention on exactly how all of these new constructs are supposed to be employed in real-life, data driven applications. you'll benefit a lot if you study tutorial from the beginning.
