I'd like to build a radar connected to my laptop. I know there are computer programs that will allow me to do that, but as far as I know they require the radar to be operated via a built-in computer, but I want my laptop to act as its computer. How do I do this?

View 11 RepliesOn my program I am trying to make a ToolStripStatusLabel's text change to "connected" if connected to a network and if not connected to a network change the text to " Not Connected" then I don't know how to display a image if connected to a network or not connected. So if the computer is connected to a network I have a image that I would like to be displayed next to the ToolStripStatusLabel. And if not connected to a network, can the program display a different image? I tried this:
My.Computer.Network.IsAvailable=True(ToolStripStatusLabel2.Text "Connected")
My.Computer.Network.IsAvailable=False(ToolStripStatusLabel2.Text "Not Connected")

I'm developing an application with Visual Basic. NET. How do I create a graph or a radar system that uses data from a DataGridView?
View 1 RepliesI'm working on an ultrasonic sonar and I would like to use the computer to display a standard green radar system detecting the objects.I'm using a micro controller with the software written in C to send out the sensor's angle and position and it works fine.On the computer side, I'm using Visual Basic 2010 to read the COM port which then contains the sensor's data in numbers (sensor's angle and distance between sensor and object) which is a constant stream. On the debug screen (Textbox) I can already see all the data coming through.
Now my question is: How do I convert those numbers into graphics?More explanations about these numbers I want to convert:I have a step motor to rotate the ultrasonic sensor, and it works that way: The motor advances 1 step forward, then measure distance between sensor and object, then send these 2 values out. So, if you see the attached file, those numbers on the text box mean:
000032 -> 000: step number & 032: 32cm between sensor and object
001031 -> 001: step number & 031: 31cm between sensor and object
002032 -> 002: step number & 032: 32cm between sensor and object
003007 -> 003: step number & 007: 7cm between sensor and object
and so on...
So those are the numbers I wish to convert into graphics. The scan line would need to rotate clockwise at same speed of the step motor. And then I would like to display dots when an object is detected.

View 9 RepliesI have a vb.net 2008 windows form application that I was just assigned to work on. how to maintain and test changes to both the pre build and the post build events? Can you tell me how to test these events? My postbuild event, I believe calls a project file in the solution file that wraps files together in a bundle in debug mode. Can you tell me how the posbuild event works and when it is called?
View 2 RepliesI am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?
I just created a simple application. I Builded that using build->build myapp. I got .exe of that application. i runned. all went fine. but when i closed that app, even after closing it is in memory. it is still running. how to deploy it properly?

I have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.
