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.

.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?

I have an access database that exports an Excel spreadsheet. Currently I have to open the spreadsheet, select all, format columns/autofit and do the same for rows.
Is there VB code that can automatically do an autoformat?
Thanks!

This code comes from an Excel VB macro:
Public Sub OpenExlFile(ExcelPath As String)<br />
Workbooks.OpenText FileName:=ExcelPath, Origin:=xlWindows, StartRow:=1, DataType:=xlDelimited, TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False, Tab:=True, Semicolon:=False, Local:=True<br />
Workbooks.Application.Columns.AutoFit<br />
'Workbooks.Application.Columns.AutoFormat<br />
'Workbooks.Application.Rows.AutoFormat<br />
End Sub
The last two lines were commented out because they badly slowed down opening the document, but they do also work.
For what it's worth,
Johan
My advice is free, and you may get what you paid for.

I'm using VS2005 and clickonce technology. When I publish a new version of my program to my clients their isolated storage settings do not upgrade to the new version I've published.
When using app config or user config settings on the 2.0 framework, you can use the Settings.upgrade code to pull the settings up to the new version published.
Is there similar code to pull my isolated storage settings up to my new published version?

This is from one of the previous thread and I only got one response. One of the good fellow at CodeProject told me to use Struct. But I know there is a natural way to customize the controls to have more than value or to change their value type.
There is a object called DataGridViewCell which can be inherited to create my own myCustomGridViewCell
But the thing is how can I tell the DataGridView to use myCustomGridViewCell instead of default DataGridViewCell. I know there is a way but trying to figure out. This will be easiest way of saving as many differect values as possible in one cell. And you can easily Set or Get them by:
DataGridView1.item(0,0).myValue1 = "This is first Custom Value"<br />
DataGridView1.item(0,0).myValue2 = "This is Second Custom Value"<br />
DataGridView1.item(0,0).myValue3 = "This is third Custom Value"
I can create myCustomGridViewCell by creating a Public Class (as shown below)
<br />
Public Class myCustomGridViewCell<br />
Inherits DataGridViewCell<br />
Public myValue1 As String<br />
Public myValue2 As String<br />
Public myValue3 As String<br />
End Class
The problem is how can I tell the DataGridView to use myCustomGridViewCell
There will be a way to override the DataGridView1 class to define my custom obects.
