Sending Data To Another Form In A Network ?
Jul 30, 2010
How i can send data from one form to another form through a network? i'm not asking for the codes, i just want to know what i should do to accomplish this task. i'm conceptualizing a game with the following details:
1.) there are two players, connected through a network
2.) they take turns looking for words from a puzzle of randomized letters
3.) after the given time has elapsed their words are checked and if both players has the same word, the word is removed
4.) the score is tallied
My question is, how do i get the words from the other form? specifically, how can the server form get the words from the client form? is it possible if i use xml? or can the server form access the variables of the client form? (i don't think it can, though)

I have looked over this and can't see where i'm going wrong, all i'm trying to do is add an item to a listbox when i a tcpclient logs on to the server. Code in question... If i put a breakpoint in i can see that initialclientresponse is set correctly.
Public Sub ConnectClient()
Dim pendingClient As TcpClient
Dim InitialClientResponse As String

We have large IBM Infoprint printers. I need to read a bunch of PDF files off a database, merge them together, and send it to one of these printers. I need to be able to specify many options such as what tray to use, with/without staple, etc. All of these options can be manually set when I try to print something off my computer (via the advanced print driver preferences), so I am certain that these can also be set programmatically. How can I do this in .NET (Visual Basic)?

What I need to be able to do is send a command across a specific network port (eg. 2124) to a specific ip address. I already have writen the recieving code (for the iPhone os) and accepts commands like:
filefound("Name of file",filetype,size)
All this is to be sent in plain text and once received the iPhone will then send a command like:
nextfile()

i havent had problems in visual basic all the ay up to this point. I have been given a shopping cart program that I must use: a MainForm, MP3From, AlbumForm, and a module
I finally got my program to send data from the listbox on my MP3Form to the listbox on my MainForm but something isnt right still. I need to be able to click an an item from the lstMP3(listbox on MP3Form) to lstShoppingCart(listbox on MainForm) multiple times without having to close the MP3Form everytime to add the items to lstShoppingCart. Here is what I got so far on my MainForm:

This assignment makes me mad cause we have not even covered half the stuff I am having to use in this form at all this semester. If i can get a little explanation on instantiate, inheritance, and declaring and object variable and how its used to transfer data from one to the other.

Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

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

I've code this code below:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim hwrRequest As HttpWebRequest = HttpWebRequest.Create("http://www.example.com/web-service.php")
[Code]....
The MsgBox() at the end shows the response, which as I've added to my script, echos the result from the $user and $pass variables which are supposed to retrieve those details being written to the stream above, but they show up empty.
I'm retrieving those values by doing: $user = $_POST["user"]; $pass = $_POST["pass"];

I have a form in my project with a textbox that contains a unique computer ID number for the user. I want the user to click a button, which will open my website, and then populate the value from my software into a corresponding computerID form on my website.
The form on my website is just a paypal form that I built using paypal's website builder. It has a buy it now button and a textfield for computer ID. I need to know the computerID so that I can send the user the correct activation code.
Is there any way for me to accomplish this? All I have so far is just opening my site:
Private Sub btnpurchase_Click(sender As System.Object, e As System.EventArgs) Handles btnpurchase.Click
Process.Start("mywebsite")
End Sub

I've built an IPv4 Header/Datagram implementation and a TCP Header/Datagram implementation - I can verify that all my code is fine (checksums computed right, < 8bit values computed right, etc).
When I try to use System.Net.Sockets and I specify any ProtocolType (including Unknown), the Socket simply refuses to send any datagram where the Protocol Field value in the IPv4 Header doesn't precisely match the ProtocolType. No error or exception is thrown; the socket simply doesn't perform the send.
This means I can't use a raw socket to send customized IP or TCP datagrams, which means I can't communicate with servers that have customized implementations of these basic protocols.
All I need is to push this raw data to the network. I'm not married to System.Net.Sockets - be happy to just shove my data on the network, since the packet headers are fine.

I'm having a heck of a time figuring this out, the tutorials I found on the web are not complete or are for VB 6.0 (obsolete in some cases). On the C++ side I have the following ::
hwndExternalApplication = FindWindow(NULL, L"Dromocast Client");
SendMessage(hwndExternalApplication, WM_SETTEXT, NULL, (LPARAM)"Hello");
"Dromocast Client" is my visual basic application, and I checked to make sure it's not NULL. In fact I get made sure I'm getting some data on the VB side. On my Visual Basic side I have the following
[Code]...
When I send the data over it's garbage, meaning strTemp comes out as all these chinese characters, and my title bar on the visual basic program gets garbled with a bunch of chinese characters as well. My guess is my "SendMessage" is written wrong, or I'm doing something silly, but I have no idea what. I'm not a windows programmer so I'm kinda trying to figure this stuff out by googling.

I am currently writing a visual basic program that gets data from a serial port. everything is connected up but the data is not received until my device on the other side is turned on on the other side. which condition can i use in my loop to ensure that i only start comparing when i have started to receive so that my loop will not hang as there is no data input?

Currently I had write a simple VB code, my aim is when i click "Forward" button then the vb will send a character "A" to PIC, "Reverse" button will send "B" so I write my vb code for sending as below:
Dim Forward As Char = "A"
SerialPort1.Open()
SerialPort1.Write(Forward)
For the receiving part, after I received the data from PIC then I will show it at the label which act it as a screen. the receiving code as below:
SerialPort1.Open()
receive = SerialPort1.ReadChar()
If receive = "A" Then[code]....

i have a similar question so i thought i might post it here rather than clutter the place with a new thread, if that's okay.first off, i'm using VB 2010 Express, if that makes any difference.second, i'm trying to send data to form2 from form3 rather than the other way around. i'm still pretty much new to VB, but have a lot of experience in PHP and some in java. i'm making a basic program that creates critters on form3 and then adds them to a table on form2.[code]then adds a value of 1 to the progress bar (i still am trying to figure out how that works) on form2.

I have a program that I collect data using a com port. I display that using special visual controls - no problem here.
What I would like to do is to send this same information out over the network via ethernet to another PC located in another room.
I presume I would have to have another copy of the program on the second pc as the information is simply duplicated but I am not sure how to get the data out of one to the other

In my app, I need two separate items. I need one item to be the administration panel that can edit information being shown on a remote computer, and I also need another item that will display the information. How do I get my program to talk across a network to edit the information being shown on computer 2? I'll also need to know then how to make the installer ask which part of the program it needs to install, and then install the appropriate part.

I'm creating a search form using an asp:button control with the urlpostback set to a results page. The problem is, the asp:button uses Visual Basic and the search results from Google require Javascript.
Is there a way to take the data from an asp: textbox in VB and then send it to another page that uses Javascript and use the data?
