MS Access: Get value from string
I am trying to get this VBA code to run after a user inputs data into a form. The script will calculate the charge which equals before-after
I am defining the name of the textbox who values i want to use (Ex:"before_1,after_1,charge_1) as a string and then use those values in the CalCharge Sub.
Any ideas why this code does not work? I believe this method works in C#, but not in VBA.
Private Sub before_1_AfterUpdate()
before = "before_1"
after = "after_1"
charge = "charge_1"
Call CalCharge(before, after, charge)
End Sub
Private Sub before_2_AfterUpdate()
before = "before_2"
after = "after_2"
charge = "charge_2"
Call CalCharge(before, after, charge)
End Sub
Sub CalCharge(before, after, charge)
charge.Value = before.Value - after.Value
Exit Sub
End Sub

Regardless of the fact that you are using undimensioned variables, I would say that the problem is that you are not referring to the controls in CalCharge.
Try to use this:
Private Sub before_1_AfterUpdate()
Call CalCharge(1)
End Sub
Private Sub before_2_AfterUpdate()
Call CalCharge(2)
End Sub
Private Sub CalCharge(ByVal index As Long)
Me("charge_" & index).Value = Me("before_" & index).Value - Me("after_" & index).Value
End Sub
I restructured it a bit:
CalCharge awaits a numeric parameter now, defining the 'set' of controls to be used by an index.
Your event procedures before_1_AfterUpdate() and before_2_AfterUpdate() now just call this new CalCharge procedure by providing the index.
CalCharge now references the controls by building the control names first.
Me is a reference to current object instance, your form, where the current code is in.
