If we have a string that contains for example "01_1A" in ascii, I would like to take first two chars and following two chars after mark and send it as hex format, like &H1 and &H1A.
Note that I would not convert ascii to hex. I am asking for something like &H(var).

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 have downloaded the vb script and it works as it should, its a program where you have some buttons so that you could trigger the relays.But i need several small scripts, one for each relay on / off so that i can call them from a .bat file with argument.i have a .bat named relaycard and in thet i have created argument like
relay1on
relay1off
relay2on
relay2off
and so on.
The small program relay1on should just do the jobb and then close itself.Maybe its a little bit clearer now.On the link that i posted there is a manual and even links to the vb program,

What I have done so far is place the compiler inside the bin of my project folder, inside the Debug folder. I managed to call the cmd shell but the problem is whenever I pass commands to that cmd shell, it doesn't work. What happens is it opens a cmd shell and when I pass commands on it, it opens many other shells.[code]...

I've got a curious problem that I can't crack. I have 2 applications, app A and app B. Application A runs continuously doing various things. On the same machine I have application B that runs infrequently at random. I need for application B to tell application A to do something. Both are vb.net apps that I've written and can tweak to make this work. I can't figure out how to get app B to communicate with app A while app A is already running?

I'm running Visual Studio 2010, and i'm trying to use AT commands to send an SMS. My question is will it not work with windows 7 due the exclusion of hyperterminal in windows 7. (I was able to dowload a version of Hyperterminal and can use AT commands in that.. but my code itself does not work.) My code is below.

In VB6, I use CHR$(&H00) to create a Null Character. In VB.Net VS2008 CHR(&H00) creats a Null. I'm trying to send a Hex(00) to a serial device, but the VB.Net function only sends a null, not a null character. How can I accomplish this with VB.Net?

I have a dll that I can load in another program. Now the dll has access to all data/functions in the other program. Which technology can I use that now an external program can send data/commands to that dll, to steer the other program, or get data from it ? I mean, in the past that meant DDE, I think that was back in Windows 3.11/95 times. What can I use today? Which one is easiest ? Which one is fastest?

I want to make a simple program where I can click a button and it send various commands to my VPS server through SSH. I have had an extensive search online but the SSH Components range from $200-$500 which is far to expensive for what I want to do. I was just wondering if anyone knows any other free alternatives. Or maybe has seen a free SSH Component. I am very well aware that free clients exist like putty but would very much like to incoperate it into my own program to be automated.

How can i use the address bar to send commands to a external application?
Example:
AOL Instant Messenger -
I havent used this application in a long time. But i remembered if you wanted to add a friend to AIM from their online profile it directed them to a link such as:
aim:addfriend=contactID
and AIM would pick this up and add it the contactID to the application. The link i posted is more than likely not the correct link they use but it shows what im trying to accomplish.
Im looking to achieve something along the lines of:

Will the commands I send to a Process.Start() be obeyed from within the IDE? [code]This doesn't work in the IDE, just gives me a blank window with the full string as the window name, but I'd like to fire up ffmpeg from within the app, wondering if it's an IDE thing or my code. I know some things in Flash work differently in the IDE than the "real" thing, not sure if VS does it too.

I want to send a simple command, such as "v20" followed by a carriage control character, to a heating/cooling block connected to a desktop computer running Windows XP. I am able to get the commands to work within a terminal emulator. I want to compile a simple program that will be executed by software used to control a liquid handling robot.I've looked at the how to send strings to serial ports in visual basic page and modified that code ever so slightly to send the data that I want. However, it does not work and my heating/cooling block is not changing temperatures.
Here's what I have written:
Sub SendSerialData(ByVal data As String)
data = "n65"
' Send strings to a serial port.
