hi there..
i assume that u know how to use formula field.
so i'l gonna solve your problem as:
use a variable which stores the value of the previous row result and then add this variable to the sum of the current row result.
i hope you got it..!

Hi,
I´d like to save a file in an oracle database over oledb. The code was allready running for sql only. But it has also to work with oracle. So i changed my connection from sql to oledb. But since that it don´t work with booth. Something is wrong with the parameter @data in booth cases. Has anybody an idea?
Private Function SQL_Save_this_PDF(ByVal selection As String, ByVal where As String) As Boolean
Dim oledbConn As OleDbConnection
If Not CcPdfViewer1.pdffile = "" Then
Dim id As String = ""
Dim bindata As Byte()
Dim strm As IO.Stream
Dim filename As String = CcPdfViewer1.pdffile
strm = New IO.FileStream(filename, IO.FileMode.Open, IO.FileAccess.Read)
ReDim bindata(strm.Length - 1)
strm.Read(bindata, 0, strm.Length)
strm.Close()
filename = My.Computer.FileSystem.GetName(filename)
If dbms = "oracle" Then
oledbConn = New OleDbConnection("Provider= OraOLEDB.Oracle; Data Source=" + server + "; User ID=" + database_user + "; Password=" + database_pwd + ";")
Else
'mssql
oledbConn = New OleDbConnection("Provider= sqloledb; Data Source=" + server + ";Initial Catalog=" + database + "; User ID=" + database_user + "; Password=" + database_pwd + ";")
End If
Try
oledbConn.Open()
Static save_pdf As OleDbCommand
save_pdf = New OleDbCommand("Insert into dateien (id,name,data) values ('" + id + "','" + filename + "',@data)", oledbConn)
save_pdf.Parameters.Add("@data", OleDbType.LongVarBinary)
save_pdf.Parameters("@data").Value = bindata
save_pdf.ExecuteNonQuery()
Thanks, Daniel
Catch e As OleDbException
MsgBox(e.Message)
oledbConn.Close()
Return False
End Try
bindata = Nothing
End If
Return True
End Function

Found it. Just change the parameter @data in the oledbcommand to "?".

Hi all,
Now i am working with a checkedlistbox. Can i sort the checked items in a checkedlistbox. In other words , I want to display the checked items in the top of the checkedlistbox. Any suggestions would be appreciated
Thanks

Sounds like you'll have to load the checked items into a list, then the unchecked items into another list, then clear the checkedlistbox, then add items to it first from the checked items list, and then the unchecked items list.

My Mott Community College instructor accomplished this by having a richtextbox on a form->copy the RTF information->strip the header inforamtion->concat to another richtextbox.

how will i get the cursor position in the textbox..?

Hi,
If you are looking for Mouse position in the textbox then you can do it by
TextBox1.MousePosition
Howerver, if you are for the text cursor which is called caret, then you may try the control's 'SelectionStart'.
Hope this helps .

By reading the documentation and writing a little bit of code, as always.

If you use VS 2005, you can use ClickOnce deployement.
Here[^] is a code project article that discusses it.
Here [^]is an MSDN article that discussees it.
Google [^]will yield other articles you use to research.
If you do not have VS2005 or better, you will want to research visual studio setup and deployment[^] projects.

Whenever I receive a mail an Incoming mail event needs to be fired and hence I do my processing further.
This works fine when the outlook is opened.But when my outlook is closed and if I receive the mails in the mean time, again when I open the outlook the "Incoming mail event" is not fired for all the new mail messages. What could be the problem?
How Should I handle this ?
Any Suggestions would be helpful.

Hi Experts,
I need help with a databinding in a text box, which draws a column from a dataview.
the sql statement used for the dataview is:
SELECT ArtistID, SUM(Popularity) from ArtistPopularity WHERE NOW >= PeriodStart AND NOW <= PeriodEnd GROUP BY ArtistID
The dataview is row filtered by artist id. The artist id can be selected through a combobox.
The crux of the issue is that not all artists will have a popularity, so this means there will be null values for some artists. So when you scroll through the artist id's in the combobox, only ones with popularities should come up in the dataview.
First i got an indexoutofrange exception, stating that there is no row at positiong 2, this is down to the fact that position 2 in the dataview does not have a value so i caught the exception like so:
Try
TextBox13.Text = oArtistPopularity3DT.Rows(TextBox1.Text).Item("Popularity")
Catch ex As Exception
End Try
But now the problem i face, is that the textbox does not update to the values inside of the datview now. It just remains the same as the last value, before it catches the index out of range.
How do i make it show the value in the textbox, when there is a value in the dataview.
Any help is much appreciated
thanks.
