How can i search a record from a table.
If found, display the record.
if not found display a message
I have done the following:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Search.Click
Try
Me.RegistrationTableAdapter.FillByRegistration_(Me.RegisComplaintDataSet.Registration, Registration.Text)
If String.IsNullOrEmpty(Me.Registration.Text) Then
MsgBox("L'enregistrement n'existe pas" & UCase(Me.Registration.Text))
Me.Registration.Text = ""
Else
Me.Registration.Text = Me.Registration.Text
End If
Catch ex As Exception
End Try
End Sub
I am getting the result when it is found but no message when it is not
Thanks

Stick a breakpoint in your Catch block and see what error you're missing. I'd say it's probably coming back as a DBNull, and throwing an exception when you try to cast it into a string (Registration.Text).
You might have to put it in an object first, then check whether it's a DBNull (And display the message if so), and THEN cast it into a string if it exists.

Thanks,
I am not getting an error. when there is a match, I get the correct row record as the result..
when there is no match I get blank row record..
what i want is a message to display "no match for this" then a blank row.
I hope I make myself clear
thanks alot

Alright, well if you're absolutely sure it's not going into that Catch block (Notice that with an empty catch block, your program will just completely ignore any errors)...
If it's actually not triggering an error, then it's time to check the FillByRegistration_() function... Drop in some breakpoints and keep an eye on the values when you search for a non-matching record.

Thanks
I got the solution

Try using this in your "catch" block so see the error.
MsgBox(ex.ToString)

There is a table called QCR100 containing the following information
ITEM_CODE ITEM_DESCRIPTION DCODE AMOUNT
111200 investments 24000003 1630000000.0000
111200 investments 126000005 1630000000.0000
111600 Other Assets 133000009 1700000000.0000
111600 Other Assets 150000002 1730000000.0000
111701 Leasehold 190010130 1740000000.0000
111705 Furniture 190010036 1750000000.0000
111706 Computer Software 190010141 46995799.1800
Then I created a view with this command statement:
SELECT CASE WHEN LEFT(e.dcode, 1) = '1' THEN isnull(SUM(a.Dr_bal_lcy - a.CR_BAL_LCY), 0) WHEN LEFT(e.dcode, 1)
= '2' THEN isnull(SUM(a.CR_BAL_LCY - a.Dr_bal_lcy), 0) ELSE 0 END AS amount, e.ITEM_DESCRIPTION, e.ITEM_CODE
FROM dbo.GLTEMP_CONS AS a RIGHT OUTER JOIN
dbo.QCR100 AS e ON LTRIM(a.GL_code) = e.Dcode
GROUP BY e.ITEM_DESCRIPTION, e.ITEM_CODE, e.Dcode
How I can modify this view to sum the amount for any duplicated item code and group by item code
Example
ITEM_CODE ITEM_DESCRIPTION DCODE AMOUNT
111200 investments 24000003 1630000000.0000
111600 Other Assets 133000009 1700000000.0000
111701 Leasehold 190010130 1740000000.0000
111705 Furniture 190010036 1750000000.0000
111706 Computer Software 190010141 46995799.1800

This is really a SQL question, not a VB question and should probably belong in the General Database forum.
That said, I'm having a difficult time trying to figure out what you're asking. Is it that your view is doing one level of aggregation, and you need a second (grouping then by item code)? If so, you can use the query you have as a subquery, nested inside another that performs that second level of aggregation:
SELECT ITEM_CODE, SUM(...)
FROM
(
-- original query
SELECT CASE WHEN LEFT(e.dcode,1) = '1' THEN ...
...
) x
GROUP BY ITEM_CODE

Make sure that you got something in your database tables and secondly your query is bring something to show. Best thing would be to first try your query on Management Studio and then port it to VB code.

I am designing an Urdu editor. Urdu language is written from right to left. I have implemented this by using rtb.SelectionAlignment = HorizontalAlignment.Right and using SendKeys.Send("{LEFT}") after every key user presses. I have not used the RightToLeft property of rtb because in that case the cursor remains at right side of rtb and as user presses keys the words move to left. Now I implemented justification using some code from net. I tried it on english editor, it works fine. But when I use it for my Urdu editor the cursor goes to left side of rtb and when I type smthg, words move to right side but cursor remains at left side. The code is here
Enum TextAlign
Left = 1
Right = 2
Center = 3
Justify = 4
End Enum
<DllImport("user32", CharSet:=CharSet.Auto)> _
Private Shared Function SendMessage(ByVal hWnd As HandleRef, _
ByVal msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
End Function
<DllImport("user32", CharSet:=CharSet.Auto)> _

SendMessage(New HandleRef(Me, Handle), _

End Sub
Public Overloads Property SelectionAlignment() As TextAlign
Get
Dim fmt As PARAFORMAT = New PARAFORMAT()
fmt.cbSize = Marshal.SizeOf(fmt)
' Get the alignment.
SendMessage(New HandleRef(Me, Handle), _
EM_GETPARAFORMAT, _
SCF_SELECTION, fmt)
' Default to Left align.
If ((fmt.dwMask & PFM_ALIGNMENT) = 0) Then
Return TextAlign.Left
End If
If fmt.wAlignment = 1 Then
Return TextAlign.Left
ElseIf fmt.wAlignment = 2 Then
Return TextAlign.Right
ElseIf fmt.wAlignment = 3 Then
Return TextAlign.Center
ElseIf fmt.wAlignment Then
Return TextAlign.Justify
End If
End Get
Set(ByVal value As TextAlign)
Dim fmt As PARAFORMAT = New PARAFORMAT()
fmt.cbSize = Marshal.SizeOf(fmt)
fmt.dwMask = PFM_ALIGNMENT
fmt.wAlignment = CShort(value)
' Set the alignment.
SendMessage(New HandleRef(Me, Handle), _
EM_SETPARAFORMAT, _
SCF_SELECTION, fmt)
End Set
End Property
I tried with this change
If ((fmt.dwMask & PFM_ALIGNMENT) = 0) Then
Return TextAlign.Right
End If
But it doesn’t work. Can anyone plz tell me how to make it work for urdu language?

I checked it out but I need to change the code. In this code when I justify text, the text is justified from left to right. I want to change this code so that after justifying text retains its right alignment.

I've been landed with an existing spreadsheet that has a data connection that is used to import some data when it opens. Then they run a macro to organize the data and a few other bits. All is working well.
Now I need to write a macro to save a copy of this workbook, but without the data connection and the macros.
Any pointers welcome!

So you just want to save the worksheet(s) data without any of the macros? Is that correct? And you want to do this with another macro or do you want to do this through .Net?
|
|
|
|

Yeah - and with the data connection removed.
Need to do it using VBA ideally.

Assuming the data and the macros are in different worksheets you should be able to use worksheet saveas in a macro. Look into the options on saveas. I have not written VBA for 15+ years so I may be wrong but I used to record a macro and examining the content to see what MS did.
Never underestimate the power of human stupidity

I'll have to have a look on Monday to see where the macros are actually located.

About 10 for me, and I don't plan on needing it again - what a PITA!

Hi
I am using the EditingControlShowing event and casting eventargs to a combobox object to get the combobox selectedindex. This works fine when i first select the combobox but before the dropdown.
How do i then trap combobox selectionchanged events?

Hi all
Though its great to have new features with every release, it sucks if Microsoft takes away old stuff that worked actually great.
I have a searchtextbox with a search button.
And what I want to build in is if someone enter something in the textbox and press enter it should hit the underlying code.
For this I need to use the textbox Keypress Event.
If you look at the code below, I get an error:
Event 'KeyPress' cannot be found
I have to use VB, its the company's policy.No Javascript
Private Sub SearchTxt_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles SearchTxt.KeyPress
If Asc(e.KeyChar) = Windows.Forms.Keys.Enter Then
GoButton.PerformClick()
End If
End Sub
Thank you for your time

Can't test it in 2008 at the moment but you can just use the 'keydown' event.
Private Sub TextBox1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
If e.KeyCode = Keys.Enter Then
gobutton.performclick()
End If
End Sub
