rewriting a class I use for saving Treeview data to a XML file for use of saving ListView data I can't really figure out the rewrite, I'm stucked, unfortunately Listviews seems to be a big problem for me in general.
Option Strict On

''' The TreeViewDataAccess class allows the nodes within a TreeView to be

A variety of files (pdf, images, etc.) are stored in a ntext field on a MS SQL Server. I am not sure what type is in this field, other than it shows question marks and undefined characters, I am assuming they are binary type.
The script is supposed to iterate through the rows and extract and save these files to a temp directory. "filename" and "contenttype" are given, and "data" is whatever is in the ntext field.
I have tried several solutions:
1) data.SaveToFile "/temp/"&filename, 2
Error: Object required: '????????????????????'
???
2) File.WriteAllBytes "/temp/"&filename, data
Error: Object required: 'File'
I have no idea how to import this, or the Server for MapPath. (Cue: what a noob!)
3)
Const adTypeBinary = 1
Const adSaveCreateOverWrite = 2
Dim BinaryStream
[Code]....
This works, but the file should be saving to the server instead of popping up save-as dialog. I am not sure if there is a way to save the response to file.

I'm trying to create a simple Data Grid that will automatically save changes. So far I have a data grid connected to a MS Access 2007 Database that reads the data. I can create new fields in the Data Grid, but I need to program to save the data automatically to the database on update (or on close).

Basically iv got a form, and the fields are
"Full Name":
"Amount Contributed in �":
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith
Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged

I need to control a device with a GPIB port. I have the commands that I need to use to do this; but I don't know which is the sintaxis in Visual Basic.
For example if I need to send a instruction like "START:0.01" to the external device which are the libraries that I have to include?, how should I write the programming line to do this?
The main tasks that I need to program are sending data, receiving data, and saving data

So here is the error...
An error occurred while saving the Panel. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index at System.ThrowHelper.ThrowArgumentOutOfRangeException() at System.Collections.Generic.List`1.get_Item(Int32 index) at PanelController.Save(Int32 ID, FormCollection FormValues)
During debugging, I checked the parameter it was adding to the save stored proc, and the ID it was adding was 0. Then, when it used this
oDal.Execute("Lending.uspPanelSave")
Item.PanelId = oDal.Parameters("@PanelId").Value
To retrieve the ID to return it, it set it as 1000? Anyone know what the problem is?

I need to solve the following problem:- Create a server application which generates a random number every second- Have any number of client applications access the current random number through a dll (associated to the server) at anytime How would I do this? Anyone has a prototype VB.Net code for the server which does this kind of thing? I'm pretty sure I know how to write the client code.
