Hello
I started to edit my old vb.net - windows program. I could not cut,copy,paste,delete anything ( button, panel, label) on windows form. I can add for example a new button but can not delete it ?? If I start a new project everything works. How to get my old project editable again? I use Vb.net 2003 std.

hi ,
i wrote following code -->
MyCommand.CommandType = CommandType.Text
MyCommand.CommandText = "SELECT CustName FROM cust_mast;"
MyCommand.Connection = conn
MyDataAdapter.SelectCommand = MyCommand
MyDataAdapter.Fill(dt)
''---------------------------------
DGTimeSheet.AutoGenerateColumns = False
CombCust = New DataGridViewComboBoxColumn
With CombCust
.DataSource = dt
.DataPropertyName = "Custname"
.ValueMember = "Custname"
.DisplayMember = "Custname"
.HeaderText = "Custname"
.DropDownWidth = 200
.Width = 90
.MaxDropDownItems = 3
.FlatStyle = FlatStyle.Flat
End With
DGTimeSheet.Columns.Insert(0, CombCust)
DGTimeSheet.Columns(0).Width = 235
''-----------------------------------------------------
now wht i wnt is->
i wnt to take one more combobox which is filled with customerID & at runtime when we select item in datagridview's Customer comboColumn , it should set current index of that other customerID
comboBox same as datagridview's customer comboBox column.
(coz i have to fill next combocolumn, depending on which customer, i have selected in that row.& as custid is primary key, i require related customerID of selected customer)
As it is possible for our normal comboboxes by writing code-->
Private Sub cmbcust_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles cmbcust.SelectedIndexChanged
cmbCustId.SelectedIndex = cmbcust.SelectedIndex
End Sub
d
but i didnt get the current index of a combobox that is in datagridview
Will u please tell how shuld i do it.
--Regards Priya

.NET 2005 has classes for it, I think. 2003 and 2002 do not.

Hi, I just install visual studio 2005 standard edition. But I need two additional feature that integrate with visual studio. First I need to have a visual studio too for Ms. office in the project template and Second I need have crystal report to be integrated with visual studio. From here, I have the below question:
1. After I purchase vs.net for ms office tool, do i need to uninstall vs.net 2005 standard edition or just upgrade via the installation CD/DVD?
2. Vs.net 2005 standard do not have crystal report integrat with. Is it possible for me to purchase the separate crystal report product to install and make it integrated with vs.net 2005 standard? If possible, which crystal report product version that I require to purchase?
Thank in advance!!!

I am trying to convert the Wininet code from VB 6 to VB .NET.
The function FtpCallbackStatus(ByVal hInternet As Long, ByVal dwContext As Long, ByVal dwInternetStatus As Long, ByVal lpvStatusInfo As Long, ByVal dwStatusInfoLength As Long) As Long
does not work with VB .NET
I tried the "delegate" and other method and it did not seem to work.
Does anyone know the quick fix for this?
