How to: Receive Strings From Serial Ports in Visual Basic. 2 minutes to read.In this articleThis topic describes how to use My.Computer.Ports to receive strings from the computer's serial ports in Visual Basic. To receive strings from the serial port.Initialize the return string. Dim returnStr As String = '.Determine which serial port should provide the strings.
This example assumes it is COM1.Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see.The Try.Catch.Finally block allows the application to close the serial port even if it generates an exception. All code that manipulates the serial port should appear within this block. Dim com1 As IO.Ports.SerialPort = NothingTrycom1 = My.Computer.Ports.OpenSerialPort('COM1')com1.ReadTimeout = 10000Catch ex As TimeoutExceptionreturnStr = 'Error: Serial Port read timed out.' FinallyIf com1 IsNot Nothing Then com1.CloseEnd Try.Create a Do loop for reading lines of text until no more lines are available.
DoLoop.Use the method to read the next available line of text from the serial port. Dim Incoming As String = com1.ReadLine.Use an If statement to determine if the method returns Nothing (which means no more text is available).
If it does return Nothing, exit the Do loop. If Incoming Is Nothing ThenExit DoEnd If.Add an Else block to the If statement to handle the case if the string is actually read. The block appends the string from the serial port to the return string. ElsereturnStr &= Incoming & vbCrLf.Return the string.
A number to identify the new serial port. #PBAny can be used to auto-generate this number. SerialPortName$ Text identifier for the serial port, for example 'COM1' on Windows or '/dev/ttyS0' on Linux. Bauds: Defines the speed of the serial connection and can be one of the following values. To receive strings from the serial port. Initialize the return string. Dim returnStr As String = ' Determine which serial port should provide the strings. This example assumes it is COM1. Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see OpenSerialPort.

For more flexibility, the code should allow the user to select the desired serial port from a list of available ports.

Typename )Form Designer RAD PureBasic has its own designer to aid in the creation of forms for applications, but other third-party solutions are also available. The original non-integrated Visual Designer was replaced with a new integrated Form Designer on 14 Feb, 2013. User community PureBasic provides an online forum for users to ask questions and share knowledge. On 6 May 2013 the English language forum had 4,769 members and contained 44,043 threads comprising 372,200 posts since May 17, 2002.Numerous code sharing sites show PureBasic is used to create tools and games in a fast and easy way, and share large amounts of open-source code.
