Print To A Specific USB Port?
Dec 29, 2009
im a independent programmer and my most recent job has me doing somthing ive never had to work with before and i was hoping to get a few answers here or be pointed in the right direction
question 1
is there a way to print to a specific USB port in VB if so links to reading material or better yet code
question 2
is there a way to program to open and send and recieve information from a USB port lpt port and a serial port using VB
and if so can i again be directed to some reading material or better yet code
i understand these are not typical questions but they are a small part of a bigger whole that we are trying to implement while we look into using Vb as the language we will use

How can I ask my tcpListener to listen to particular IP on specific port? I want my tcpListener to listen to the local IP of the machine. I can get the ipaddress of the pc using Dns.GetHostAddresses(). But, if pc have multiple ip's how can I know which ip address is correct? From tcpClient class I am connecting to the server. So, I know the server ip and so I want to specify ipaddress to my tcpListener class to listen on.

I tried to make a winsock program.But when i run, i have a SocketException "No connection could be made because the target machine actively refuse it."Any suggestions on what i should do? Im using 17477 port.By the way Im using my own computer to test it. So i have no idea why.How should I open this specific port in my own computer?
Is it possible that I could include it to could into my program so that i don't need to open the ports of each computer? Below is my code.

I am working on writing a program that needs to send a command to a specific port on the same computer, I have that working fine. There is another piece of software running that is listening to that port for some commands (read on).
Dim myTcpClient As New TcpClient
myTcpClient.Connect("127.0.0.1", 61225)
Dim networkStream As NetworkStream = myTcpClient.GetStream()
However when I try to send a command I get no response...
Dim outStream As Byte() = System.Text.Encoding.ASCII.GetBytes("0x33")
networkStream.Write(outStream, 0, outStream.Length)
networkStream.Flush()
I have been given a list of protocols that I need to send to that port. What I have been told is that the size (in byes) is 1 and the value is "0x33" with no parameters. I am completely new to sockets and sending data through tcp.

whether or not I can print a specific page from a .pdf?
The VB application has a folder of images, the same image has a large and a small size to accommodate for screen resolution. The application gives you the ability to print either image. Problem is that both of the images are blurry. The same image contained in the .pdf is crisp and sharp when printed from within the .pdf.
Can I have the VB application print a specific page in the .pdf? or is there a way to copy the sharp .pdf image and place it in the folder of images?

I'm sure this is a common problem, but I haven't been able to find it.
I have a website and I want the user to be able to print a rectangle on their printer that is 3.5 inches x 2 inches. Exactly (within reason).
EDIT: To clarify - I'm looking to print a bunch of multicolored Text within a rectangle that needs to be a specific physical size. I also need to print specific shapes around some of the letters.
I'd looked into some of the .NET Printing stuff and found examples of measuring/drawing strings and shapes; but I didn't see anything that would let me specify a specific size.

I've had a search through a number of extremely useful articles on the forums, however rather than reinvent the wheel I thought I would ask if anyone already had what I am looking for..A simply little VB app that opens a session to a specific IP port and then writes to a test file everything it receives. If the connection drops, simply re-stablish it and keep listening for text to write to the file.

I am trying to implement a custom printing solution for a client. What he wants is to have one button print a certain set of info to a specific printer and specific printer tray, connected to the client machine. Another button will print a similar set of info, to the same printer, but a different tray.
One tray is preloaded with regular 8.5"x11" paper, and the other is loaded with legal paper, 8.5"x14". I've found some instructions on how to do this: [URL]. So, I've implemented the code, and am able to enumerate the printers attached to the client machine, and their trays.
I've setup some web.config settings for the client to enter the names of his printer and specific trays (in this case, tray 1 and tray 3). This code I've written runs and works correctly, printing the document without error. The problem I am having is that even though I have selected the tray for legal paper, all the info instead prints on regular paper, the printer seems to be ignoring my instruction to print onto legal paper.
Here is the code:
Imports System.Drawing
Imports System.Drawing.Printing
....
Private printFont As Font
Private ds As dsSummons
Private formToPrint As FormType
[Code] .....
I first tried "pd.DefaultPageSettings.PaperSource = PSource" but that didn't seem to work. I also tried setting "pd.PrinterSettings.DefaultPageSettings.PaperSource = PSource" but that doesn't seem to work either..

I am trying to figure out how to print specific members of a structure when I only have to pass the structure itself i.e.
Dim Point1 as PointF = New PointF(15,30)
Debug.Print(Point1) ' This will output "{X = 15, Y = 30}" by default
I am trying to figure out how I can do the same with my own strucutres, for example:
Dim Point2 as PointF2D = New PointF2D(15,30)
Debug.Print(Point2) ' This will output "ClassName.PointF2D.Point2"
How can I get my structures, when passed to a print statement, to print specific members of that structure by default? P.S. Please give another way other than overloading the .ToString function.

Ypos = TopMargin + Count * PrintFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(ROData(x, 3), PrintFont, Brushes.Black, LeftMargin, Ypos, New StringFormat())
Count = Count + CInt(ROData(x, 4))
The above line prints the data contents of the ROData array in position three. I would like to be able to assign a specific position accross the line to have the printer print the data at without left padding the array data.

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!
