VB2010 : Make A Local Port Forwarder?
Jul 28, 2011
I'm trying to make some kind of local port forwarder,this means an app which would in my case forward port 10972 to port 25565.This is because of safety precautions. I did a whole lot of work on searching and coding myself, but without succes. Probably it works one way, but not backways. I think the response doesn't work. I really don't know what to do now.
Public Class PFS
Public Sub New(ByVal IP As String, ByVal listenPort As Integer, ByVal sendPort As Integer)
Dim hostIP As IPAddress = IPAddress.Parse(IP)

I am writing some software that should respond to commands from a port.
How do I set up a handler to respond when data is recieved at that port.
Do I need to do anything special, like respond or set up the port in the first place.
I don't have any experience doing anything like this!

I am writing a vbs to create local port to connect to our printer server (i.e local port for \PrintServerPrintQueue1). I can create the local port succesfully through editing the registry HKLMSoftwareMicrosoftWindows NTCurrentVersionPorts and then restarting the spooler service in Windows 7 32bit. However, the same script cannot create the port in Windows 7 64bit. The registry was also changed but cannot create the local port after restarting spooler service. Does anyone know what difference between 32bit and 64bit Windows when creating the local port?

i am trying to make a webbrowser in VB2010, but one major roadblock that has been in my way for a while, is the fact that i can't get my bookmarks bar to work
i have no code to show you and i am completely open to ideas as long as i use a toolstrip just make sure that the bookmarks work and they are Saved when the program is closed and opened again.
Notes:
instead of "WebBrowser1" use:
"
CType(TabControl1.SelectedTab.AttachedControl.Controls.Item(0), WebBrowser).PutWhateverHere()
"
(i am using a dotnetbar tabcontrol so i need the "AttachedControl")
the toolstrip i am using in this case is called "BookmarksBar" so please don't use "ToolStrip1"

I have created a Windows Form inherited from an existing form using the Inheritance Picker: Project menu ==> Add Inherited Form.So now I have the Form-base (FrmP1) and the inherited form (FrmP2)The form works perfectly. If I open the "code" window of FrmP2 I can see only the main class:
Public Class FrmP2
End Class
I have added now a FormClosed event in P2:

Is it possible to make a program with visual basic 2010 that does not use the actual form but instead only uses other components (e.g. Message Box) to form a complete program?

is there any way to make the app load and compile local dll?
an exemple:
All process over visual studio 2010
i made an app on win7 that uses shell32.dll but the way that win7 compile his own interlog.shell32.dll it makes the app don't work in XP. But if after i finish the app on win7 send the code to a xp machine and set the shell32.dll on XP the app will work fine.
so... if there was a way to make the app, at his first load, do search from needed dll to compile them for his needs, it will was fantastic.

I am trying to make an application to listen in on a UDP port - the issue is that there is something already there. Here is the scenario: On port 5060 is a SIP-based softphone, it is listening for incoming calls. The application I am writing is also listening on port 5060 to receive the packets (which will then be parsed to extract the caller ID and various other statistics)

I'm creating a WPF application in VB.NET with the 3.5 Framework. (If you provide an example in C#, that's perfectly fine.)
In my project I have a Template for an MS Access database. My desired behavior is that when the users clicks File-->New, they can create a new copy of this template, give it a filename, and save it to their local directory.
The database already has the tables and some starting data needed to interface with my application (a user-friendly data editor)
I'm thinking the approach is to include this "template.accdb" file as a resource in the project, and write it to a file somehow at runtime?

I have a chat server / client system running, but I want users to authenticate with my vBulletin forum database.I don't want the client to do it, because it is possible to fake the 'successful login' and connect with a fake username. I want to send the username and password details to the server, and make the server check it with the local vBulletin MySQL database for the username and password.Is there a way to do this? To my knowledge vBulletin has a username and a password entries in the database which is salted, and the salt varies from user to user.

I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?

I am trying to get my 4 port USB relay board to work in VB.net using the COM PORT. I found some code from a poster who has the 16 port USB relay version. When trying his code i can only get it to turn on relays 1-3 all at the same time. The product can be found here: USB 4 port relay
"01+//" - Relay 1 is switched ON
"01-//" - Relay 1 is switched OFF
"02+//" - Relay 2 is switched ON
"02-//" - Relay 2 is switched OFF
[code].....
So i am confused as to how to separate each relay out with that code above and just be able to turn on any number 1-4 relay on or off independently from each other!
