Alternative from LostFocus

Hi,

For some reason in my application, i don't use LostFocus Event from TextBox, ComboBox, etc. I made some function that able to detect (logically) whenever the user want to leave TextBox, ComboBox, Etc then do whatever thing it should do before leave (TextBox, ComboBox, Etc).
But When user leave TextBox, ComboBox, Etc by mouse my function wasn't able to detect it. How to solve it?

Thanks

PS: sorry for my english.

Could you show us the function please :)

You can use the Validate event. Its similar to the lostFocus event, but allows you to cancel the focus change.
Example

Code:

---

Private Sub Text1_Validate(Cancel As Boolean)
    If Trim$(Text1.Text) = "" Then Cancel = True
End Sub

---

Hell-Lord:
Nothing fancy in it, and my mistake to say that "i able to detect it when ever the user want to leave TextBox" but i set whenever user hit the prefer key on keydown event it will do what it prefer to do.

Andrew G:
Yes Andrew all those TextBox and ComboBox in my application are using Validate Event. But My Problem is i made my input form is in Row (something similar Microsfot Excell).
User can move to another row only when current row are complete. Problem arise when focus on column 3 then user mistyping "2234" instead "1234". Then user corrected it to "1234" while focus still on those column, user can click away to another row (and validate event --TextBox or ComboBox-- will true) although column 4 and column 5 wasn't fill yet. I hope you got what i mean.

Thanks

Are the textboxes in an array? What are they called?

no Andrew, it;'s not on array. And on those 5 column there are 3 TextBox, 2 ComboBox.

Thanks

Not sure if this is what your looking for :)

Code:

---

Private Sub Text1_GotFocus()
ControlGotFocus 1
End Sub

Private Sub Text2_GotFocus()
ControlGotFocus 2
End Sub

Private Sub Text3_GotFocus()
ControlGotFocus 3
End Sub

Private Sub Combo1_GotFocus()
ControlGotFocus 4
End Sub

Private Sub Combo2_GotFocus()
ControlGotFocus 5
End Sub

Private Sub ControlGotFocus(CtrlNum As Integer)
    If Trim(Text1.Text) = "" Then
        Text1.SetFocus
    ElseIf Trim(Text2.Text) = "" And CtrlNum > 1 Then
        Text2.SetFocus
    ElseIf Trim(Text3.Text) = "" And CtrlNum > 2 Then
        Text3.SetFocus
    ElseIf Trim(Combo1.Text) = "" And CtrlNum > 3 Then
        Combo1.SetFocus
    ElseIf Trim(Combo2.Text) = "" And CtrlNum > 4 Then
        Combo2.SetFocus
    End If
End Sub

He needs to have a way of tracking at which "row" he is, such as with a control array where he will manipulate/interpret the indices. Using Text1, Text2 will not work as he'd end up making validation code for each "row" with the control names hardcoded as is the case with your ControlGotFocus() procedure Andrew_G. He can't reuse that for the other rows.

Finalize your GUI first barianto... how your implementing the "spreadsheet" or "rows" with textboxes + comboboxes. There has to be a way of interpreting which control instances/indices belong to a "row" or the current group.

Once you've done that, you can create a validation procedure that checks that all controls for the given "row" have valid values. Call this from validate event, if procedure returns false then set the Cancel argument of the validate event. Have all controls call this procedure (they pass their index).

No, andrew that's not what i want, :) thanks anyway :)

As say in post #4, user still on current column (which could be TextBox or ComboBox) but the value on those TextBox or ComboBox are true for Validate Event. WHen user hit "Enter Key" or other key that has been trap in keydown event, everything will fine -it will be focusing on next column. Problem arise when user leave from that TextBox Or ComboBox to anoher ROW using mouse. it will leave to another Row, and left two other row still hasn't fill yet.
