Excel VBA UserForm 'OK' - vba

Question

Does anyone know how to make a userform function in the same way as the Message Box 'ok' button? I'll explain.
I'm detecting errors in a column in a spreadsheet. When an error is found, a message box pops up as follows:
MsgBox "Please enter valid data"
When I select "OK" it goes to the next error in the column. This is great, except of course a message box is modal, which freezes the application. I want the user to be able to edit the data and then move to the next error. So, I designed a userform, which can be non-modal. Great, except I want the macro to advance to the next error. It will do that IF the user corrects the error. If they do not, it just stays at that error cell.
I know WHY this happens. My userform 'Next' button just calls the macro which finds the first error. But what I want to know is if there is a way around this.
Error checking starts at row 19 because that is where user input data starts.
I'm including a link to the spreadsheet here. Module 1 'NextValidationError' works great and proceeds to the next error. Module 14 just hangs at the error until it is resolved. I'd like it to be able to skip.

Can anyone give me advice on how to make module 14 proceed as module 1?

Answer 1

Something like this:
Dim r_start As Long
Sub CheckNames()
Dim r As Long
'Dim emptyRow As Boolean
If r_start = 0 Then r_start = 19
With ActiveSheet
For r = r_start To 5000
'Checks entire row for data. User may skip rows when entering data.
If WorksheetFunction.CountA(.Range(.Cells(r, 1), .Cells(r, 33))) > 0 Then
If ((.Cells(r, 2) = "") <> (.Cells(r, 3) = "")) Or _
((.Cells(r, 2) = "") = (.Cells(r, 4) = "")) Then
MsgBox "Please fill in First and Last Name or HCO in Row " & r & "."
End If
End If
Next
End With
End Sub
Unless I'm mis-reading your code you can combine your two checks with Or.
You will need some method to reset r_start when the user is done checking (if the form stays open after that).
EDIT: here's a very basic example.
UserForm1 has two buttons - "Next" and "Close"
Code for "next" is just:
Private Sub CommandButton1_Click()
ShowErrors
End Sub
In a regular module:
Dim r_start As Long
'this kicks off the checking process
Sub StartChecking()
r_start = 0
UserForm1.Show vbModeless
ShowErrors
End Sub
'a simple example validation...
Sub ShowErrors()
Dim c As Range, r As Long
If r_start = 0 Then r_start = 9
For r = r_start To 200
With ActiveSheet.Rows(r)
If Not IsNumeric(.Cells(1).Value) Then
UserForm1.lblMsg.Caption = "Cell " & .Cells(1).Address() & " is not numeric!"
r_start = r + 1
Exit Sub
End If
End With
Next r
r_start = 0
UserForm1.lblMsg.Caption = "No more errors"
End Sub
