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 have never programmed a network program before and would like to learn at my own pace. Also I am not asking anyone to write this complete program for me, just bits of code to help me write a complete program. (though if you do code it all I won't complain.) I already tried using internet tutorials but none of them seem to work.I am trying to program a simple form with 4 buttons, and 2 users.The first button is a connectivity button. "Green" for connected, "Red" for not.The second button is a "Connect" Button which will connect to another computer with this program installed/active. (I want it as simple as possible)and the next 2 buttons switch between "1" and "0" depending on user input(Default "0"). the first button is the local user button and the second is the remote user button. When the local user clicks the local button then what he/she changes it to will be displayed at the remote site. The same thing will happen with the remote user.
I know how to place all the buttons where they belong, and to change the local text, but I have no Idea how to connect to a remote program or to pass messages between the two users. Can anyone suggest some Simple code to do this. (something that I will be able to learn and use to make more complex code later on.)
I am writing a windows gui front-end for a game that uses 6 open cmd console windows. The cmd windows are already open, I do not need to launch them, I just need to be able to send a command to a named cmd window by pressing a button on my Visual Basic 2005 Express form.

How can I send commands to LAN Printer?
View 5 RepliesI'm writing a program in VB.NET 2010 that will connect to the PICkit(TM) 1 FLASH Starter Kit's USB programmer and send it commands to turn on or off something connected to the attached eLab16m board, for example, an LED. This is all done by using the libhid.net DLL. The vendor id is &H4D8 and the product id is &H32.
Update I've written a console program that outputs what's happening. Here's the output:Where it says device with report id 0x10, I am trying to query the firmware version from the USB Programmer.Update 2 I've fixed the problem with the Wacom Bamboo tablet by uninstalling its software and drivers from my computer. The error has disappeared from the command line, but it still shows the 0x10 error.

Would you have a load of public sub's to handle each or maybe something else?
I am creating an application to configure some modems through the serial port. I have no problem sending a single string of data to the serial port and displaying the immediate response to a rich text box. I have 2 problems
1st: how to update the rich text box for any delayed response from the modem
2nd: how to react to the response from the modem, in other words I want to send the next command based on the response from the modem witch is usually "OK"
This is what my code looks like currently to send ans receive data from the serial port. (sport1 is my serial port and display is my rich text box)
sPort1.Write("AT+WOPEN=1" + Environment.NewLine)
With Display
.AppendText(sPort1.ReadExisting())

I need to build an forms app that 'posts' or 'sends' text commands to an external console process, called Minecraft Server It is a java-based process, filename 'minecraft_server.jar'. Run by my computer via 'java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui'. The Process ID I assume would change each time it's run. This process can be downloaded here: [URL]
I am guessing that I need to:
1) find the Process ID for it, based on its process details, such as Command Line
2) figure out a way to 'post' these commands, commands such as "stop" into the console window
I cannot have this process launched by my VB project.
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:

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)
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)?

View 1 RepliesI have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

View 8 RepliesI am extremely new to visual basic and it is the first time i have ever tried to program anything. I am currently using Visual Basic 2008 Express Edition which I downloaded for free off of the mictosoft website. Anyhow, to the question at hand: I was wondering how one would use keydown commands in VB express 2008. I have looked far and wide and have yet to find an answer to this. To simplify it to a specifit answer how would I move (or rather, slide), say, a picturebox to the left of the screen by holding down the left arrow key and have the picturebox stop moving after I released the arrow key. By simply seeing how the code is I should be able to do it for any other keydowns.

I have a very large table, and I have a sql data adapter to fill a data table. The user is able to change some values, then saves the changes, at this point i just call the adapter update method (I use the sql command builder to get all the commands of the adapter). What I need it's to make some changes to 4 parameters in the update command, before calling the update command, but I don't see how to do this? Before the update itself, I don't have any values, if I set the parameters (I saw the number of the parameters in the debug mode), before the update, that doesn't do anything, I think they get override in the update method...
View 3 RepliesI have an application in which I save transactions. So I have a datagridview populated with records and i test for changes in the datatable when saving.then i loop through the changed rows and save in the following order:I have a command that saves a wage.then a command that saves interest.I use this to save as a transactiondate:
acccmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
then the other command :
intcmd.Parameters.AddWithValue("@TransactionDate", tdate.Date + Date.Now.TimeOfDay)
but sometimes the code is executing the two commands on the exact same time. Now I have a query that displays a running total and on order for the running total to work properly no two transactions should have the same datetime for a particular person.how can I add a delay between the two commands to ensure the datetimes are saved differently?
i have a problem: I have a Form_Load-Method which is not doing all the commands in it. It just interrupts and jumps to the "Form_Paint"-Event, eventhough i did not yet paint anything or invalidated any object. The Form_Load-Method is this:
[Code]...
the dashed line indicates the point of termination. the for-loop is simply not done. i tried it with stop points and the last point it stops is the ReDim-part. this can only mean, that the ReDim-Command forces the program to leave the method. but the for loop is never done afterwards. Can you help me? Because i really dont get it.
i have been looking everywhere for the method used when you click the [X] Button so like that i can run some commands on form exit. I found Form_Unload method replacing Form with the name of my form and no luck. I'm sure there has been some talk on the subject but searching forum shows nothing that seems to work.
