Key press for individual comboboxes

13-Oct-06 4:23

That's nowhere near enough information to tell you anything useful.

What are you trying to do? What scanner utility? Are you talking about a flatbed scanner? Fingerprinter scanner? Document scanner??? What?

Hi,

USING VB 6.0

I have several comboboxes named cboField(1),cboField(2),cboField(3) etc. in other words they have been created this way (indexed) for the purpose of using loops whenever necessary.

Now when I use

Private Sub cboField_keyPress(Index as Integer, Key ascii As Integer)

to produce some action on the comboboxes I only get a global action (not individual to each combobox) How can I get this as I would like to produce different actions on different comboxes on keypress on the respective fields

I tried...

Private Sub cboField(2)_keyPress(Index as Integer, Key ascii As Integer) for example gives me an EXPECTED IDENTIFIER error

Thanks for your help

It's been about 6 years since I've touched VB6... but what's that Index parameter in your function header for? I'm will to bet that's the index of the control that fired the event.

Hi Dave,

I guess you mean this..

Private Sub cboField_KeyPress(Index As Integer, KeyAscii As Integer)

End Sub

That parameter I did not choose. VB puts it by default when I choose cboField and keypress from the menu. And it works fine only that it is not specific to any combobox but to all of them...
As I said I tried substituting cboField_KeyPress by

Private Sub cboField(1)_KeyPress(Index As Integer, KeyAscii As Integer)

Private Sub cboField(2)_KeyPress(Index As Integer, KeyAscii As Integer)

Private Sub cboField(3_)_KeyPress(Index As Integer, KeyAscii As Integer)

etc.

but then I get the said compilation error
Please suggest something..

Thanks

Augusto

OK, let's try this again... HAVE YOU LOOKED AT THE VALUE OF THE INDEX PARAMETER WHEN A KEY IS PRESSED??? This should tell you which ComboBox raised the event.

Dave, I think you have not understood my problem... If I writte;

Private Sub cboField_KeyPress(Index As Integer, KeyAscii As Integer)<br />
MsgBox ("Please use the drop down buttons and select an item from the list")<br />
End sub

everything functions and I get the message poped up as soon as I press a key IN ANY OF THE COMBOBOXES i.e cboField(1),cboField(2),cboField(3),cboField(4) etc.

My problem is that I want to have a specific message for each one of this combo SEPARATELY

How do I do that???

And I think your missing the purpose of that Index parameter.

Private Sub cboField_KeyPress(Index As Integer, KeyAscii As Integer)
    Select Case Index
        Case 1:
            ' The first combobox fired KeyPress
            MsgBox "Hi from ComboBox 1!"

        Case 2:
            ' The second combobox
            MsgBox "Hi from ComboBox 2!"

        Case 3:
            MsgBox "Hi from ComboBox 3!"
    End Select

All you had to do was check the value of Index...

Hi,

I also used a prepaint routine in a project. The following routine will pre paint a cell either red or blue depending on if it's positive or negative.
I'm sure you could use something like this to fix your problem, if you refresh the grid the colours will be repainted again in the correct location.

See below......

Private Sub grdAdjustments_RowPrePaint(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewRowPrePaintEventArgs) Handles grdAdjustments.RowPrePaint
Dim tmpCellPos As New DataGridViewCellStyle()
Dim tmpCellNeg As New DataGridViewCellStyle()
tmpCellPos.BackColor = Color.FromArgb(30, 124, 230)
tmpCellNeg.BackColor = Color.FromArgb(253, 92, 65)
Try
If Me.grdAdjustments.Rows(e.RowIndex).Cells(2).Value > 0 Then
grdAdjustments.Rows(e.RowIndex).Cells(2).Style = tmpCellPos
Else
grdAdjustments.Rows(e.RowIndex).Cells(2).Style = tmpCellNeg
End If
Catch ex As Exception
ErrorCodeLog(ex.Message, ex.InnerException, gstrACTIVEFORM)
End Try
End Sub

Hope this helps
John

And that would be ....?

Print what file? A text file? A PDF file? Word document? What? Do you want your application doing the printing or are you trying to get the application that wrote the file to do the printing? What part of the printing process are you having a problem with?
