Visual basic serial port datareceived event code#

'I tried the code in a windows form and I get the same results 'Visual Studio slightly changed this from the example on Microsoft's website that used a Windows Form TxtReading = .GetString(comBuffer) & CStr(CInt(comBuffer2) / 10) 'part 3 - concatenate read data and convert to single type MySerialPort.Read(comBuffer, 0, n) 'read data from the buffer UpdateFormDeligate1 = New UpdateFormDeligate(AddressOf UpdateDisplay)Дim n As Integer = mySerialPort.BytesToRead 'find number of bytes in buffД¬omBuffer = New Byte(n - 1) 're-dimension storage buffer (n - 1) 'Handles serial port data received events Could anyone help with a way to modify this code? Private Sub mySerialPort_DataReceived(ByVal sender As Object, ByVal e As SerialDataReceivedEventArgs) I know that the instrument received and processed the second command, but it never appears in excel. Using the code below, the tools work great to collect a single reading, but when I enable the code to send a second command to the instrument the Data Received event stops working entirely until I send another single read command. I'd like to set it up so that I can push one button and have it collect two separate readings in different worksheet cells. I currently have the COM connection set up correctly and it will allow me to send and receive one command at a time.

Visual basic serial port datareceived event update#

The DataReceived event will not necessarily occur on the same thread as your form UI so you need to use a thread safe call to a new function if you want to update form components in response to data being received.I'm working on a VSTO add-in for Excel 2013 in VB.NET that will help me interface with an instrument via a serial connection. Void Mењњlass::serialPort1_DataReceived(System::Object^ sender, System::IO::Ports::SerialDataReceivedEventArgs^ e) If (serialPort1->IsOpen) //Port should not already be open

SerialPort1->PortName = 'COM' + CommPort In a function that wants to set the port number and open it SerialPort1->DataReceived += gcnew System::IO::Ports::SerialDataReceivedEventHandler(this, &Mењњlass::serialPort1_DataReceived) SerialPort1->Handshake = Handshake::None SerialPort1 = gcnew System::IO::Ports::SerialPort() System::IO::Ports::SerialPort ^serialPort1 To create a new event, such as datareceived press the lightning bolt 'events' icon in the properties box and double click the event you want to create. You can set its properties by selecting it and using the properties box Place the serialport from the tool box onto the form (not the old Comm control that used to be used in VB). (This is no use if you want to use in a seperate class!) STemp = System::Text::Encoding::UTF8->GetString(aTemp)
