.net - Basic UDP C# Or Pipe ?
Aug 31, 2011
Looking for a basic UDP Pipe or redirector. Should of course be able to see both client 2 server and server 2 client data.Here is what I tried but it fails because I don't know when to call which Receive..Say I call
data = serverUdpClient.Receive(sender)
Then I have to reroute this, so I call this
clientUdpClient.Send(data, data.Length)
[CODE]...
Pretty much the code flow is all fucked.. because it's socket is blocking. When I started working on UDP.. all examples say stay away from non-blocking as it's too advanced for newbie's trying to work with networking sockets.. I find that statement wrong.. the other way around!.
Public serverUdpClient As System.Net.Sockets.UdpClient
Public clientUdpClient As System.Net.Sockets.UdpClient
Sub runProxy()
[CODE]...
Also tried this.. doesn't work properly.
While True
If serverUdpClient.Available > 0 Then
data = serverUdpClient.Receive(sender)
[CODE]...

I have a perplexing problem. I have written a DB App using SQL Express 2005 as the back end and Visual Studio 2005 Standard VB.Net as the front end. I have a master DB that needs to import from an external database from another SQL Express server. I detach the DB from that server and attach it to my server. I import the data I need, close all connections to the import DB and try to drop it from the server since it is no longer needed. Yet one active connection remains so I get a drop error. To get around this problem, I set the import DB to single user with roll back immediate and then drop the database. However, when my application tries to access the Master DB I get the follwong error
A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

I have a lot of Microsoft SQL Backup files. The application should restore each backup-file with
RESTORE DATABASE {0} FROM DISK = '{1}' WITH REPLACE
Then I fill another database with some data from the restored database and drop the restored database with
DROP DATABASE {0}
If I only restore one backup-file, no problems. The data from this backup is in the new database and the restored database is dropped. But if i use more than 1 backup-file, i get this error:
German:Fehler auf Übertragungsebene beim Senden der Anforderung an den Server. (provider: Shared Memory-Provider, error: 0 - Kein Prozess ist am anderen Ende der Pipe.)English (something like): Error on transportlayer while sending the request to the server. (provider. Shared Memory-Prover, error: 0 - No process on the other end of pipe.)

Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file. I cant seem to figure out how to write this same code in VB instead of VBA.I am currently using Visual Studio 2010.Here is the code for my Macros that work fine but I need it in the application and not on the spreadsheet.

Just trying to get EXIF information using ImageMagick. If I set the variable command to:-
"C:Program FilesImageMagick-6.6.2-Q16identify.exe" -ping -format "%[exif:*]" "C:est.jpg" >c:exif.out
And then:-
Shell(command, AppWinStyle.Hide, True)
I don't get an exit.out file. There's a delay so it's clearly doing it. Obviously the same line from an actual command prompt does work! And I get an exif.out file... Any idea how I can shell that command off and get an output file?

Now i'm coding for a project in VB.net that allow user to browse to text files (i am done), after that i have to import this text file into access.
The problem i have to import a pipe delimited file (it is: #), that '#' help to distinguish each filed.
Example: my text file is: #BC2323#23241#12345. This mean that: There are 3 fileds in it: BC2323; 23241; 12345.
There is my coding for browse any text file:
Private Sub btnBrowse_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnBrowse.Click
Dim alltext, lineoftext As String
OpenFileDialog1.Filter = "Text files (*.txt)|*.TXT"

I am writing a VB.net client to write to and read from a named pipe in byte transmission mode.I learned from the MSDN article that CallNamedPipe() only works for message-type named pipes.
So do I have other choices, or do I have to change the pipe server code to message type.

I have 2 applications that needs to talk to each others. After some research, I wanted to go with managed pipe (namespace system.io.pipes). The problem is, the client must send commands to the server but need to also wait for incoming message from the server at the same time. I tried to go asynchrone but it doesn't work.

So i'm new to working with vba in access and i'm having trouble getting this code to work. What it is suppose to do is take a selected text file and read the original file into a list box. Then there is a second button that when pressed will convert the text file from a pipe delimited file into a tab delimited file and then show the changed file into a new listbox.
Option Compare Database
Option Explicit
Function GetFilenameFromPath(ByVal strPath As String) As String

I'm trying to just get a VB.net app to be able to execute a lua script in a external file, and be able to add some functions to lua too, To do this I have this code:
Imports LuaInterface
Public Class Form1
Public luascripting As New Lua()
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
luascripting.RegisterFunction("DisplayText", Me, Me.GetType().GetMethod("DisplayText"))
luascripting.DoFile("script.lua")
End Sub
End Class
But it errors on the register function, saying "Object reference not set to an instance of an object." Do you know of a example VB.net project that uses lua? Or know how to fix this?

BASIC and its variants Visual Basic and VB.NET are the only programming languages I know of that treat the end of line character as a statement terminator (I'm excluding batch files and command scripts from the domain of programming languages). I'm curious: is there any other language that uses this convention, or does BASIC stand alone?

I remember we were taught BASIC (Beginner's All Purpose Symbolic Instruction Code) language in school, when we were in 5th grade. It was purely in DOS-Mode and we basically used it for drawing. Then I learnt Visual Basic 6.0 quite a few years basic. I neve found a similarity between them

I run this with a breakpoint on the first line, update my VB.NET datagridview (which updates and saves just fine), but the breakpoint never gets hit. Am I going about the setup of the trigger incorrectly?
