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...

I use ColouredDataGridTextboxColumn for my Datagrid.I override its Paint Method and apply colur to entire row depending upon a column value.
It works Fine till this Point.
The Problem Is:when i Click on the Datagrid Header to sort the colmn(this grid has default sorting enabled)the rows chage but the colour does not change according to new values.
Will be very Thankful to anyone who can provide solution for this

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

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?

Well, you can cheat and do it. Drop a WebBrowser control on your form, load the document you want to print into it, then call the WebBrowser's Print method.

First of all, you are confusing dates with strings. A date value doesn't have a format at all. The format is applied when you convert the date value into a string.

If you get a format that you don't want, it's because you have converted the date to a string without specifying what format you do want. If there is no format specified, it uses the format of the current culture.

When converting a date to a string, you can specify a specific format:

s = daDate.ToString("dd/MM/yyyy")

You could also specify a DateTimeFormatInfo or a CultureInfo object for the culture that uses the format that you want.

Tip: Use the methods of the DateTime structure instead of the VB6-ish methods:

daDate = DateTime.Today.AddMonth(-1)

---
b { font-weight: normal; }

You can use tostring

or

dtpTextStr= DateTimePicker1.Text()

How is this text file exposed on the AS400?? Is it available via a web page? FTP server? Telnet? Without knowing how this file is made available, it's impossible to tell you how to get at it.
