My datagrid displays data from an Access table. The table has 10 records yet the datagrid displays 11 rows - the 11th row being blank. How can I keep from displaying this row?

Thanks in advance for any help.

This allows you to add new rows to the data. You'll have to set the AllowNew property[^] of the DataView, that your DataGrid.DataSource property is bound to, to False to turn this off.

What if the DataGrid.DataSource property is a DataSet instead of a DataView - how do you set the AllowNew property?

Look at the example in the link I gave you. It shows you how to create a new DataView object to bind your DataGrid.DataSource to.

Another question
In my datagrid would like to paint rows and cells in different color, to mark if changes have been made and so forth. I've made my own textboxcolumns but i'm not pleased with the result, partly because theese columns "overrides" the datagrid function to color up the rows when you click on the rowheader column. Language - vb.net. Tips, anyone???

Hi I'm working with an application where it would be desirable to preserve several columns in a datagrid for comboboxes (for choosing and searching). I've tried to fix it but it doesn't seem to work. Do anyone have an idea how to do this?? I'm working in VB.NET.

Hi
I have a form with 7 datagrids each with between 2 and 10 columns. These are bound to DataViews which are bound to DataTables. I use DataVeiw.RowFilters to display the required data. I dont want to display all the columns in the DataGrids. Below is code to set up the first two columns of the first datagrid - another 6 to go... Any ideas how I could loop through the columns of each table, and perhaps pass the function an array of the desired column widths (setting hidden columns' column width to 0) for each table?

Tks

Private Sub InitialiseDataGrids()

Dim TextCol As DataGridTextBoxColumn
Dim ts As DataGridTableStyle
ts = New DataGridTableStyle
ts.MappingName = dtBOMDetail.TableName.ToString
TextCol = New DataGridTextBoxColumn

'Table 1 Col 1
TextCol.MappingName = dtBOMDetail.Columns(0).ColumnName
TextCol.HeaderText = dtBOMDetail.Columns(0).ColumnName
TextCol.Width = 200
TextCol.NullText = "0"
ts.GridColumnStyles.Add(TextCol)

'Table 1 Col 2
TextCol = New DataGridTextBoxColumn
TextCol.MappingName = dtBOMDetail.Columns(1).ColumnName
TextCol.HeaderText = dtBOMDetail.Columns(1).ColumnName
TextCol.Width = 300 'Hidden Column
TextCol.NullText = "0"
ts.GridColumnStyles.Add(TextCol)
Me.dgPartsList.TableStyles.Add(ts)

And so on..... another 50 times!!!

A DataGrid doesn't have any data to look at. You should be looking in the DataSource (property) that the DataGrid is using. This is usually a DataSet or DataTable object, which should be retrieved from a database anyway.

Hello there
I have a desktop application using webservices at backend. the problem is when I upload the file of more then 100MB it says after some time that "Connection time out". I increased the IIS - webservice time out property but even now the error is coming. my idea is that it is coming due to connection time out property of desktop application.

any information or suggestion will be appreciated to remove the bug

Sendmessage from VB6 to vb.NET, please help.

Hi,

I'm trying to send a windows message from vb6 to a vb.net app. The problem is that I can recieve a message, but the string I send with it is not recieved correctly by the vb.net app. When I try to put it back into a string again I get garbage.

Here is some code from the sending app (vb6):
<code>Private Sub cmdSendData_Click()
Dim sString As String
Dim lHwnd As Long
Dim cds As COPYDATASTRUCT
Dim buf(1 To 255) As Byte

sString = Trim$(txtString)
If sString = "" Then Exit Sub
'
' Get the handle of the target application's visible window.
'
lHwnd = FindWindow(vbNullString, cWINDOW_TITLE)
'
' Copy the string into a byte array,
' converting it to ASCII. Assign lpData
' the address of the byte array.
'
Call CopyMemory(buf(1), ByVal sString, Len(sString))
With cds
.dwData = 3
.cbData = Len(sString) + 1
.lpData = VarPtr(buf(1))
End With
'
' Send the string.
'
Call SendMessage(lHwnd, WM_COPYDATA, Me.hwnd, cds)
End Sub</code>

And here is the recieving app(vb.net):
<code> Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
If m.Msg = MainForm.WM_COPYDATA Then
Dim data As CopyData
Dim message As String

' get the data...
data = CType(m.GetLParam(GetType(CopyData)), CopyData)
message = Marshal.PtrToStringAuto(data.lpData, data.cbData \ Marshal.SystemDefaultCharSize)

' add the message
Messages.Items.Add(String.Format("{0}: {1}", DateTime.Now.ToShortTimeString(), message))

' let them know we processed the message...
m.Result = New IntPtr(1)
Else
MyBase.WndProc(m)
End If
End Sub

Private Const WM_COPYDATA As Integer = &H4A

<StructLayout(LayoutKind.Sequential)> _
Private Structure CopyData
Public dwData As IntPtr
Public cbData As Integer
Public lpData As IntPtr
End Structure</code>

If I send the same message from a vb.net app then everything works.
Can anyone tell me what I'm doing wrong?

Thanks!

ok fixed it!

changes (in the .net code):

[code]
'message = Marshal.PtrToStringAuto(data.lpData, data.cbData \ Marshal.SystemDefaultCharSize)
Dim B(255) As Byte
Marshal.Copy(data.lpData, B, 0, 255)
message = System.Text.Encoding.Default.GetString(B)

overriding ListView's Paint event

I've been trying to override the ListView's Paint event as I need to handle this event in my Windows Forms Project.

I've managed to get the Paint event to fire (as desired) but any items that I add to the ListView are not visible. I am completely clueless when it comes to custom draw controls but I suspect that as I'm overriding the paint event I'm going to need to draw the items I add.

Can anyone point me in the right direction in terms of what I need to do to be able to see the ListViewItems that I add to my custom ListView?

Here's the code that I'm using to expose the paint event.

Thanks,

Karl
