Communications :: Cannot Find MComm Control In List
May 16, 2010
I am using VB10 Pro. I am trying to add an MSComm to a project. I have tried to follow this example: [URL] which utilizes VB6 but cannot. Instead I right clicked the mailbox, selected Choose Items, but could not find Microsoft Comm Control 6.0 in any of the tabs. After doing a search I found another example.
From that one you go Project | Add Reference | COM.
But again Microsoft Comm Control 6.0 does not show up in the list. Where is MSCOMM? Doing some further research, I do not have mscomm32.ocx in my C:WindowsSystem directory.

I am in the process of designing a computer control program to control a HF communications receiver (radio), and have found a problem with the Serial port. I am using VB Express Edition 2008. This module of the program is supposed to take an input string from another part of the program, format it, break it into 4 bytes, and send it to the radio in hex form via COM port 1. The problem comes in when you try to enter a frequency with an 8 or a 9 in it. The 8 or 9 is usually replaced by 45, ex.-input 9900, receiver tune 4545. The exact same thing happens with 8's, input 8800 and receiver tune 4545. All other numbers other than 8 or 9 work fine. The strange part of it is that sometimes the 8's and 9's work, and work correctly. For instance, 900, 1900, 2900, 3900, 4900, 5900, 6900, and 7900 all work correctly. This led me to believe that is may only be when the 8 or 9 is in the first position, but that is not the case, it also shows up in other positions as well. All other frequencies that do not have 8 or 9 in them also work. I ran into this same problem with VB Express 2005, and worked on it for weeks before giving up and going back to VB6.0. This same module (with exception of the port open command) runs flawlessly under VB6. I have even tried importing the MSCOMM control from VB6, but it gives the same results. In de-bugging mode, all of the inputs, decimal and hex seem to be correct, so the problem must come in after you click the command button, but before it leaves the COM port.

I have a small embedded web server and to setup its network parameters I use a serial port, however this is giving me a lot of trouble due to USB to serial adapters (in some computers work in other doesn't).
However the other day I saw that Buffalo has a little program to find their NAS boxes (or network drives) when you don't know their IP address or got the wrong one so I assume they do it by looking for mac addresses.Is there any way of doing this with VB 2005 or higher? Basically I don't know the IP of the embedded server so I need to find it on a network, how do I find it?
a) I could do a general IP scan assuming it is on the same subnet than the host computer
b) if it has a different subnet... a general IP scan is not going to work, is it?

I whould like to find the IP address of a game server that sends UDP packets to my PC. Of this server I know the fixed Port number, but not the IP address
I can read the netstat -anp udp data and store them in a text file... but this command don't displais the IP Address and the Port number of the external servers, only lots of asterisks
the question is: how to retrieve this IP address?

I am using VB2008 SerialPort to communicate with a device. My problem is, using RTS handshake I am missing the first 50 or 60 chars, after that everything is intact. I tried to change the buffer size - Has no effect, used standard, bigger, smaller and no change.
The device timing says when it sends CTS signal, it will start listening 100ms after that. I have no clue how to delay the write to test this. Should I first write to the buffer then write to the port after a a 100ms timer event?

We learned How to assemble an input/output control board that would connect to your serial port. We were able to use out statements (back in the old gwbasic) to send output signals to the parallel port to turn on/off different outputs. The board had connections where you could connect lights, relays, etc, and had connections where you could attach switches and sensors.
I have been looking for something simple that I can manipulate in my programs. I already have an ActiveHome X10 interface which includes an activex for receiving and sending x10 signals (home automation, turning lights on/off, etc.). I want something that I can straight out connect relays to, and sensors as well. I don't want something that connects to the serial port since that is already being used up, the parallel port would work fine, or even better usb.

I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

when I add a Control to the List(Of Control) what gets added to the List? Is it the Control or reference to the Control.I have a collection of controls (picture boxes representing notes,comments, icons, etc.), which can be drag and drop into other picture boxes holding read only images. Those controls are never permamently added to those images, they can be move or dispose as needed. I need to save those controls to a file and retrieve it later, however when retrieved, they must be place onto the same location in the image. Saving just the image is not the option, I also need to save all the control attributes.

After reading all the examples for list of T exists and Find and find first, none show how to handle multi-property objects. Below is bare bones example maybe someone could flesh out to show how this should be done.
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DatePriceList As New List(Of DateAndPrice)
DatePriceList.Add(New DateAndPrice(Date.Parse("1/1/2000"), 10.12))
DatePriceList.Add(New DateAndPrice(Date.Parse("1/2/2000"), 11.12))

I am writing a program using editable list boxes that will then be compared to a string later. I have no problem editing the listbox, but I am having trouble figuring out how to compare the list of things to the string. I envision using either a "for/next" loop or a "do/while" loop.
Mostly, what I need is the way to read the list box one entry at a time, in order.

This Questions has properties QuestionID and QuestionAnswer. While iterating through this List of Question in foreach, I have to find .QuestionID = 12. If I find .QuestionID = 12 then I have to immediately assign a value to .QuestionAnswer = "SomeText" of .QuestionID = 14.
I don't want iterate again inside .QuestionId = 12' to find.QuestionID = 14` again.
Is there any way I can go directly to .QuestionID = 14 using LINQ?[code]...
