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 am writing an application to gather, display and export system information for use with a Support Dept.Is there a performance difference between using WMI and My.Computer.X.X in VS 2005? Is one method better practice than the other?There are more lines with WMI, but am willing to write more if it's considered good practice over using My.Computer.X.X.

View 1 RepliesWe have an assignment at school to make a programm with visual basic that helps the user choose a computer, better give him a choice of 3 PCs.the following code is how far we are with comparing but we are knew to VB so...
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim num1, num2, num3, num4, num5 As String
Dim i, j, x As Integer
Dim help(5, 13) As String

sol() is a global variable that contains the characteristics of our 14 computers (in our own format, lol) which we then compare to the users input (via combobox). With "ordi" we "format" the choise of the user to match our format. then the grand comparing begins... the first for-loop should select the computers which fit best but we don't know how to "skip" that computer if the comparison doesn't fit (after all, we still want to use that computer for a second or third choise!). After that the next for-loop should pick the best fitting computer as no.1 (going from top priority down).
I am told that the code does not seem to contain any reference to a template file for controlling the device. This information might be in the array StatoCubo, and perhaps the text file is used to populate that array, but there is no code here to do that.

View 2 RepliesI need to have a PC talk to a Mac (apple) over a network (or alternately the internet, SSH, whatever works) in such a way as to open a shell window on the Mac to execute a number of commands to have it talk to a UNIX box and transfer files from a device attached to the Mac to the UNIX box where it can then be accessed later on in an shared area (SAMBA) by the PC.
The Mac has a fixed IP and I can have it configured to open the appropriate ports, but I would like to minimize any potential security issues.
Part of the reason why is the copy time is significantly lower. Copying from the PC to the shared area takes over 90 minutes vs about 10 for the Mac. No doubt this has to do in part to translation and network overhead.
So I need to
1) Connect
2) Open Shell window
3) Execute commands
4) exit Shell window
5) Disconnect.

i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
I am developing a computer application designed to monitor the network and CPU statistics on a computer remotely. The monitored computer would have my program installed and the monitoring computer would display, in a form, the information being sent from the remote client.The application does not send any information regarding packets, user names, passwords, etc. It is solely meant for monitoring CPU performance and Network resources remotely.
What would be the best method to send this information over to my host machine?I am programing in Visual Studio 2008 on windows XP. The client machine is also XP. I know this sounds a little shady, but it is required for my little business (http://www.iquorum.net) to monitor what and when something happens on our machines when I and my employees are away.
i have encountered a problem, i want to access the data coming to the computer from the in-built bluetooth module of a computer on windows platform, this data has been sent by a remote bluetooth module say a by an autonomous device (just like a bluetooth mouse connecting to the computer).
