I'm fairly new to Visual Basic (VB), but I've already got running code to access all my serial port. The problem is I want to load multiple serial ports into an array and loop through them in my functions. The program allows me to create ports(), but fails when I try to populate it.

Dim ports As IO.Ports.SerialPorts()
ports(0) = SerialPort1

Where SerialPort1 is an object I draged from the Visual Studio toolbox.

I did some research online, but have not found anything relevant to resolve my issue. Does anyone know what the issue might be and the possible solution to it?

Unable To Close Serial Port After USB / Serial Converter Disconnected

Mar 28, 2006

I have a stand alone VB.Net 2005 application that uses a serial port that generally stays open while the application runs on a Windows XP system. In trying to bullet-proof the UI, I ran into a problem when the USB to Serial Converter normally used to provide the serial port is disconnected while the serial port is open. In trying to handle the resulting error when accessing the port, I find I cannot close the port.

When trying to do so, the error message says something like "unable to close the port. You may not have sufficient permissions." Reconnecting the USB/Serial Converter does not reactivate the port.

Make An Array And Put Result Every Time The Serial Port Gives A New Result?

Oct 14, 2009

I am encountering the following issue So i have a device that sends stuff at the serial port, i then parse it and put it into an array of bytes like that:

Dim HCI_Command_Rcvd_Byte() As Byte All good till here What i wanna do is make an array and put this result every time the serial port gives me a new result, for example:

[Code]...

Basically what i wanna do is let the port parse the messages, fill in the array with the result at an empty spot in this array and then i will have a separate thread that will look in into this array in each non empty space and after it looks into the non empty space it will use or discard the info and also mark this space as empty (after it checked)

VS 2008 Serial Data - Make Sure The Correct Data Is Received?

Jun 28, 2009

I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.

My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected

eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

VS 2008 Make One Application Send A Task To Another Application / Receive Result From That Secondary App?

Apr 26, 2010

is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?

Enable Application To Run On Server / Network Share So That Only Serial Number Needed Is For Server?

May 29, 2012

I have an application I have developed which works great on individual PC's. However I've had some interest from a few customers that asked if I have a network version for site licencing.If my app did not save any data or write any reg entries, this might have been ok. But it does to the local computer. I also built in my own copy protection and trial function that stores data in the registry on the local computer.What would I need to do to enable my application to run on a server/network share, so that the only a serial number needed is for the server?

Make An External Application 'child' Of Main .Net Application

Jan 23, 2010

I use SetParent to make an external application a "child" of my Main .Net application. This works fine.What I need to know is why can't I use Me.MDIChildren(0)I thought that using SetParent would increase the number of children by 1, thus allowing me to reference it with the above code, but it shows there are no children in the array.I have been trying, without luck, for 2 days to try to maximize an external app being displayed in my app. I can get it to display, but I would love it if it could Dock to the same size as its container (a panel)
