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?

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,
icdavid
|
|
|
|

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

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.

I don't have the proper answer for you but I know "for sure" that if you look in the windowsmedia SDK you'll find what you're looking for. Probably even the DirectX has some classes for that.

This forum is specific to vb.net so your question could be appropriate if you are to use that language.
Let's suppose you're about that ... if you look around here you should find some code for handling SMS under vb.net. Just type SMS in the search box here and you'll get several articles that procide a good starting point

I have many radio button lists with the options YES and NO. I am trying to get it display or hide a text boxes below depending on whether the user checks YES or NO. However, because I have many radio button lists on my page, I do not want to use the autopostback feature because it will keep on bringing me to the top once the command is ran.
I got it to work using the OnSelectedIndexChanged command with the autopostback but I find it annoying to scroll down all the time to continue.
Is there anyway I can get this to work without using the autopostback feature?

You can only do this in client-side JavaScript. You cannot do it using VB.NET. Any code you write on the server side will require a postback to the server in order to work.

And how would I do that? I have try using client side programing but i need to use a web control textbox becasue I have to save the info in the textboxes to my database.....
THanks

I have no idea since I can't remember that much Java. You might want to try asking in the Web Development or ASP.NET Forums. But this is most definately beyond the reach of server-side ASP.NET code.
