Displaying Voltage level into Oscilloscope waveform

Hello. I have another enquiry and need guidance on the following :


As mention in another thread ( if you have came across it --> Getting voltage from RS232 & allow dial voltmeter to point according to voltage level ), my circuit board is connected to a power supply(those laboratory DC power supply used in schools) and the circuit is connected to the computer via a RS232 Serial cable port.

Thru the serial cable port, a voltage level is sensed and is displayed on the "Voltage Level in Volts(V)" -- See attach image

With the help and suggestions from people in VB forum, i am able to display a Dial Voltmeter with a needle.

As for now, i am also needed to display the voltage level into another type form intead of just Dial Voltmeter.

Maybe to display the voltage level to a waveform like what we see on the oscilloscope ?

I came across a suggestion from someone regarding the oscilloscope, but its in C# instead, and after converting, the codes does not work. Hmm.. ?

>> Therefore, i hope to get some guidance on how to display the voltage level into a waveform as what we see on the oscilloscope.

>> Please also feel free to voice out any other suggestions you have in mind other than oscilloscope waveform ?

Once again, if any of the above is unclear, please inform me.
Thanks in advance. :)
