I am trying to make a network tool. And i cant find how to make a a portscanner.
So i taked a look at the internet and founded the following code:
Private Sub btnScan_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnScan.Click
Me.CheckForIllegalCrossThreadCalls = False 'Now you can Add items through a thread
[Code]....
It gives me the following error : 'Add' is not a member of 'System.Array'
The following code get an error in IDE when ADD method is used on Methods4Cost. Generic List of should work fine but IDE complains "'Add' is not a member of 'System.Array'".
System.Collections.Generic
Dim Methods4Cost() As List(Of CostMethods)
Dim values As String()

I got this error within my code and haven't been able to figure out what is wrong with it,im not sure if im doing this Array Correct that could be the reason just looking for some guidance.

why the following code
Dim myStrings(My.Settings.test.Count - 1) As String
My.Settings.test.CopyTo(myStrings, 0)
DataGridView1.DataSource = myStrings.Select(Function(s) New With {.Value = s}).tolist
would be giving me grief in an existing app but work fine when i put it a new project starting from scratch. I'm getting the following error:

I haven't had this problem before. For some reason, when I declare a variable,I.E.rand as a new random(), and try to use rand.Next, i get an error saying 'Next' is not a member of system.array. Not sure why this is happening.

im making a port scanner and stuff so can you give me the coding for it with a progress bar ill do anything on the form i have a button and a progress bar
View 8 RepliesI have a vb.net 2010 application and I would like to get the scanner info (modal name, port, etc.) attached with my PC. I use windows xp SP 3 in my machine and Cannon scanner is attached with my machine.
View 1 RepliesCurrently the scanner is in a module (code below). I put it at that level because when I had it in a class and instantiated the class from the main form, no other forms except the main form would fire the DataReceived event. Well, unfortunately that's the case for the module-level as well.Here's the code for the Scanner:
Code:
Imports System.Threading
Imports System.IO.Ports

i need to create an application where input are to be received by the barcode scanner.However, i am not suppose to use the textbox to do so. However i need to use the serial port to do so. Any one know how am i able to do that?
View 1 RepliesI am developing a Winforms application which read barcode from barcode scanner. It's an Human wedge scanner. This will work if I placed the cursor in any textbox or notepad. But i don't want like that. Reason is that it's cordless scanner. If some want to scan some thing in store they will move around, so there is possibility of screen saver coming or system gets locked if that happens the barcodes wont capture, but the user who is scanning the barcodes won't know this thing.
So i am reading the data using serial port communication and my scanner sending the data character by character, Not a whole string. so for that I wrote the following code. Thsi code will works if i am writing to any textbox. But it is not working if want to store it in any global string. Only first character is storing in the string. The below code is working perfectly fine. but if want to save the string in Global String variable instaed of textbox the only first character in the string is storing.

I am using Richard L. Grier's Enhanced Serial Port dll to read input from a serial port barcode scanner I notice that the datareceived event fires only once per barcode scan, but the delegate sub fires twice per barcode scan. Once for 1st half of Barcode , 2nd for 2nd part of barcode This makes it hard to capture the full barcode so it can be passed to routines in my vb.net 2008 windows application In Richard's example 'Test Enhanced Port' program he sends it to a textbox using .selectedtext and it works fine Richards Delegate code ......................
Public Delegate Sub DisplayData(ByVal Buffer As String)
'This delegate routine marshals receive data from the receive thread context DataReceived to the Windows Form STAThread context

I am trying to set a variable to the full barcode to pass to routines, instead of writing to a textbox but am not having any success
I've been trying to translate some code from C# to VB.NET, but I have three lines in my translated code which are giving me headaches. All three of them read like this variable = Win32.CreateEvent(HANDLE.Zero, False, False, Nothing).The error is under HANDLE.Zero. Just like the subject line says, the error I am receiving is "'Zero' is not a member of 'System.Array'".HANDLE is declared as System.IntPtr.This is the relevant part of code in the Win32 class.
Public Shared Function CreateEvent(lpEventAttributes As IntPtr, bManualReset As Boolean, bInitialState As Boolean, lpName As String) As IntPtr
End Function
Below is the code for the complete Win32 class.

I've been reading the MSDN Library and I need to use the StreamReader.Peek Method to check a text file while a I parse it.
When I try to use the Peek Method, I get an error saying , "Peek is not a member of System.IO.Stream."
I don't understand why it is happening because I am following the examples on MSDN, and I even checked other sources and it seems like I am doing everything correct. I am hoping it is just something small that I have missed.
I am also importing System, System.IO, and System.Text.
