You can also export your C classes in such a way that VB.net can use them like you would API calls. I did this on a shell I developed so that I could get the sytem tray icons. Search google for "Use C++ DLL in VB.net". Another option is to use WndProc messages between the two applications. That's the way I would go personally. The concept you'll want to research is "inter-process communication".

Hello All,
I was wondering if there is a snippet that allows your program to follow out programming when it is terminated through task manager or similar tool. For example (Not valid code):
Private Sub OnTerminate() Handles Form1
Wondering if there is such a thing you could implement into your application  .
Simple Thanks and Regards,

There's no such thing.
Task Manager tries to shut down your app nicely, by sending a message to it exactly like the user closed the main window.
If the app doesn't respond in time, the app is stopped completely and all memory for it freed. Your code never gets a chance to respond to anything as it's not running anymore.

The original app could simply be halted by Windows, being unloaded from memory without any warning. A simple solution would be a watchdog-application; write an app that starts your original app, and have it check from time to time whether it's still alive.

Hello, I would like to as you if there is a way I can perform a reverse IP domain lookup (get all the domains of the websites that are hosted on that server) using vb.net
Something like this: http://www.yougetsignal.com/tools/web-sites-on-web-server/[^]
It would be awesome if you could provide me with the source code.
Regards,

You should start with the hardware you're going to be controlling and it's specifications and documentation. You're also going to have to learn G-Code, what each instruction means, how to parse it and translate that to motion of the tool head, ...
Judging by your question history, this project is WAY over your head right now.

Thanks for the reply , i did study G-Codes, The only thing making me confused is weather to do it in vb or C.

Here is a quick / rough way that I would count the characters in a string
Dim s As Char() = TextBox1.Text.ToCharArray
Dim p As New Dictionary(Of Char, integer)
For Each chars As Char In s
If Not chars = " " Then
Dim i As Integer = s.Count(Function(r) r = chars)
If Not p.ContainsKey(chars) = True Then
p.Add(chars, i)
End If
End If
Next

How do you know that, VB programmers aren't case-sensitive

Hi,
I'm currently developing a windows form application in Visual Studio 2008 (Visual Basic). I'm pulling information from an access database to a form. I have a combobox and textboxes, I want to autofill or populate the textboxes from the users combobox selection. I've got the combobox working fine by simply setting it's DataSource and DisplayMember properties but can't seem to get the textboxes to fill with the information from the rest of the table row.
By the way, I will have 5- 10 rows on my form. A combobox with 8 textboxes. In my experimentation I got the first row working but it filled in the information in the other rows. Any help would be greatly appriciated.

Without seeing any of your code, it's difficult to imagine how you are trying to return the data, however I guess you are populating the combo with an ID or UserName value from the database.
To then populate your text boxes, by selecting a value in the combobox could call a function to query the database.
The sql query would return the associated fields values based on the ID or UserName value selected, which are then inserted into the various textboxes.
I can provide a working example but I think you are supposed to provide some code and "we" then provide assistance.

Thank You for replying,
As I said in my initial post I've gotten the combobox working by setting it's DataSource Property and DisplayMember Property. I haven't written any code other than to establish a connection to my database, construct a data adapter and data table.
|
|
|
|
|
The answer would depend on the type of datasource, are you using Datatable? TableAdapater? DataSet? Custom Classes?
That is why you were asked to show some of your code.

Thanks for replying,
This is all I've written so far:
Public Class frmFoodLabelData
Private fdftconn As New OleDb.OleDbConnection()
Private dafdft As OleDb.OleDbDataAdapter
Private cbfdft As OleDb.OleDbCommandBuilder
Private dtFdItems As New DataTable
Private m_rowPosition As Integer = 0
Private Sub frmFoodLabelData_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'FoodDataSet.FdItems' table. You can move, or remove it, as needed.
Me.FdItemsTableAdapter.Fill(Me.FoodDataSet.FdItems)
fdftconn.ConnectionString = "Provider=MicroSoft.ACE.OLEDB.12.0;Data Source=C:\FoodFight\Food.accdb"
fdftconn.Open()
dafdft = New OleDb.OleDbDataAdapter("Select * From FdItems", fdftconn)
cbfdft = New OleDb.OleDbCommandBuilder(dafdft)
dafdft.Fill(dtFdItems)
End Sub
As I said I've gotten the combobx working by setting it's DataSource and DisplayMember properties. Hopefully I can get pointed in the right direction. Any help would be appriciated.
