I'm doing some very basic ground work, I know someone who is building a model train set and believe now you can control the track switches etc via computer, does anyone know anything about these? could something be built in VB to do this?
View 9 RepliesHow do I retrieve the computer model information?For example, I have a dell inspiron 1545. How do I retrieve that information in a label? I search a lot of WMI information but can't seem to find it. It SAYS 1545 on my system properties

View 3 RepliesI 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 utlizing a piece of code for an FTP upload process that we want to occur when the check mark is checked, The download function (virtually same structure) works extremely well and without any issues. But the uploadfile function merely creates a file on the destination path called what it should be called, but does not upload any information. I think there is some uploadstream that I have to invoke which I am not. This is just the code starting at that process.
ftp.Method = System.Net.WebRequestMethods.Ftp.UploadFile
'If we were using a method that uploads data e.g. UploadFile
'we would open the ftp.GetRequestStream here an send the data

It is my first time to program using VB. I need to use 3 buttons on the top to do different work. When each button is pressed, different screen with a lot of tool boxes pops up, but in the same form. Can anybody tell me how to switch to different screen after button switches? E.g. when program runs, the first screen pops up together with the first button. If I press the second button, do I have to write code manually to turn off these tool boxes and turn on the boxes for the second button? Any easier way using Visual Studio to draw boxes for the second button?
View 3 RepliesThis may be a dumb question, but I am stumped. I wrote a simple desktop application in vb.net (vs2005) and published it via the "deploy" method. After I deployed the app and ran the deployment exe - the application runs fine. However, I have recently added some command line switches so I can run the app via a scheduled job. But I cannot find the "exe" file in order to run the application from the command line. Am I missing something or did I deploy/publish the application wrong?

Also is there a way to run a function like that? And if anyone is wondering why then basically i am copying a script to my domain computer and executing it. This i already have done but problem is its just getting too much copyin multiple scripts and executing i would put everything in on and run em by switches.

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.

View 1 RepliesMy VB.NET application uses Microsoft Flex Grid Control 6.0. This is a legacy application which has been ported from VB6 with the Visual Studio conversion wizard. Although I can compile the assembly, I get a COMException because some class is not registered. I've found out that this class is the Microsoft Flex Grid Control 6.0.
Where can I find the control and how can I register it on machines so that the application will run?
I'm trying to create a querystring so when a user switches languages, the URL changes to ?lang=NL, for example. I have this in the code behind on homepage.master (VB, NOT C#):
Me.Request.QueryString("lang") <> Session([Global].SESSION_KEY_CULTURE) Then
Visual Studio underlines it in blue. When I hover over the left side of the statement, it says "Property Value Must Assign to the property or use its value" When I hover over the right side of the erred statement, it says, "End of Statement Expected".I'm not sure if the code I was given is C#, but when I use the Teleflex translator to check, it says "EOF Expected" and won't translate. All of this is tied into 3 classes I created, BasePage.vb, Culture.vb, and Global.vb. But I think it's just this line that's screwing everything up.

View 4 RepliesWhen user clicks on a button on my form, it sends the datagridview on that form to another class that [basically] does a bunch of stuff and shows a dialog with a print preview. Everything works perfectly fine, except that if a user switches around columns it won't print them in that current order. For example, if user moves the LastName column before FirstName column, then it should print in that order, but it prints in the column order that the datagridview was originally loaded. The dgv1, is the datagridview that was originally loaded, not the current one. [Code]

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.
