How can I monitor how many times a switch open and close? I am planning to add a label13 to my form and use the LPT port so every time the switch goes high (1) it will add 1 to my label13.text. The Printer Adaptor address in the target PC is 0x378. using pin 10 (ACK) or pin 2 (D0).

View 4 RepliesI need device switch component which an be controlled by code(.net,C# Or vb) ON/OFF state is enough. I have code knowledge in C#, .net window application, I need to make a switch that can be controlled using code via USB port ... so that using that switch I will turn on/off electrical devices (fan,light) for a specific time interval.. For my MINI Project
Note: I need the brief note regarding components needed and how to assemble it.
If you know any link which resembles this type of project pls refer me.
Our company has setup several remote devices that link to a switch Whenever there are problems on the device, some technicans will replace it using a new one We have a vb program that can automatically update the device setup in our server when technicans replace devices. So we do not need to login and update the setting manually However, our program cannot handle the case that there are more than 1 device that need replacement Therefore, our idea is to retrieve the ip and port of the router/switch that links to remote device using VB.net.

I am sending data into VB through a serial port on my computer, from a microcontroller. The data enters VB in an ASCII form, but I need it as a number. I can use the Asc command to convert numbers 0-127 however after this it dosent work. I believe this is becaus the ascii character map only goes through 127. So how can I convert the rest of the data (128-256) to a numbers?
View 3 RepliesI 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.
I created a background image for the form with rounded corners. I filled the outer edges and empty space with Lime color (00FF00) and then set the same transparency key in the properties for my form. It worked well, the edges were transparent and the form appeared round-edged. This was accomplished with Visual Studio .NET 2005 on Microsoft Windows Vista Home Premium 64-bit.The very same application was ported to a different platform. Visual Studio .NET 2005 on Microsoft Windows XP Professional 32-bit. All the settings are the same and nothing has been changed. But the transparency effect is not appearing on the Windows XP platform.

I just it is something that I'm doing wrong but I don't know what. Some of the thing that I have tried is including the images in resources.

Using any version of .NET how do you find out which zone a particular share is classified under. I am having a problem identifying if a share where my referenced dlls reside is in the "intranet zone" or "internet" zone relative to some user machine that is running my .NET application. I suspect this is a problem because I am having a problem accessing referenced dlls from a share on some machines but not others. How can I tell which zone .NET is classifying that share in so I can adjust permissions accordingly?
