use foreach to iterate through the Rows collection of your table. You can then access each property in the row using row("columnName"). Here[^] is an article on how to write text files in VB.NET.

Hello Guys,

I am trying to sign my assembly with a Strong Name.
When I try to build the program I get this nice error:

Preparing resources...
Updating references...
Performing main compilation...
vbc : error BC30145: Unable to emit assembly: Referenced assembly 'Interop.Scripting' does not have a strong name
Building satellite assemblies...
Satellite assemblies could not be built because the main project output is missing.

I am interested to know how we could sign the 'Interop.Scripting' assembly

Is there someone having a clue ?

Thanks by advance

Re: how to extract a selected row from datagrid

There are many ways to extract information, first you need to identify the index of the record you want to extract.
We can use the ME.Databindingcontext( datasource ).position to identify the current row.
Normally we assign a table to a datagrid's datasource, but here we will use the Table.Defaultview.

SO given TBL1 as your table

Datagrid.datasource = TBL1.Defaultview

then we can use

Me.BindingContext(TBL1.DefaultView).Position()

to indentify the current row, this should work even it you change the sort field of the datagrid.

I think thats it.

<br />
    Dim ID As String<br />
<br />
    'use the this event handle<br />
    Private Sub DataGrid1_CurrentCellChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles   <br />
                              DataGrid1.CurrentCellChanged<br />
        Dim x As Int16<br />
<br />
        'Datagrid1.datsource = tbl1.Defaultview<br />
        '    instead of Datagrid1.datsource = tbl1<br />
        '     you must explicitly point to the tables defaultview <br />
<br />
        'Get the position of the Table's Defaultview<br />
        x = Me.BindingContext(TBL1.DefaultView).Position()<br />
<br />
        'use x to identify you row<br />
        ID = TBL1.DefaultView(x)("fieldname")<br />
    End Sub<br />

Thanks,

I'm using a DataGridTableStyle and for the MappingName it only seems to work if the MappingName equals "TBL1" instead of "TBL1.DefaultView". Is this correct?

How can C++ control a VB-window?

Hello all,

I have a C++ console application written in .NET that I would like for to output to a Window as opposed to the DOS window.

Thanks!

Move it into a .NET dll, and then you can call it from VB.NET, and use VB.NET to show the output.

I did this once by redirecting stdout of the console to a stream with my GUI program. This works, but I would concur with the previous reply, that using a DLL is the right way to go. This is what I did, with quite a few ommisions.

Dim myProcess As Process = New Process()

Public sIn As System.IO.StreamWriter
Public sOut As System.IO.StreamReader
Public sErr As System.IO.StreamReader

'setup the process
'...
'...

myProcess.Start()

sIn = myProcess.StandardInput
sOut = myProcess.StandardOutput
sErr = myProcess.StandardError

Hi VB/Oracle expert!!

How can I utilize VB to read Oracle database?

Thanks a bunch,

Re: Oracle question

Yep have a look at this

Namespace: System.Data.OracleClient

OracleConnection
http://msdn2.microsoft.com/en-us/library/system.data.oracleclient.oracleconnection.aspx

OracleCommand
http://msdn2.microsoft.com/en-us/library/y051k82s(en-US,VS.80).aspx

OracleCommandBuilder
http://msdn2.microsoft.com/en-us/library/0ca0k1ad(en-US,VS.80).aspx

Example

The following example uses the ExecuteReader method of OracleCommand, along with OracleDataReader and OracleConnection, to select rows from a table.

Public Sub ReadMyData(ByVal connectionString As String)
Dim queryString As String = "SELECT EmpNo, DeptNo FROM Scott.Emp"
Using connection As New OracleConnection(connectionString)
Dim command As New OracleCommand(queryString, connection)
connection.Open()
Dim reader As OracleDataReader = command.ExecuteReader()
Try
While reader.Read()
Console.WriteLine(reader.GetInt32(0) & ", " _
& reader.GetInt32(1))
End While
Finally
' always call Close when done reading.
reader.Close()
End Try
End Using
End Sub

animated jpeg streaming?

Is there a good way to put an animated jpg stream on a windows form?

Lots of IP cameras use this format with a java applet to view in a webpage... Just wondering if there was a good way to view this stream from vb.net and skip the java.
