Pop up error if COM port is already in use


Recommended Posts

Oh, I am the first to post here on the 'NEW' LAVA smile.gif

Hi all,

I have COM prot selection utility done in which the Com port indicator output passes on to my program further. However, as seen in the attached file, I need to Notify user if a particular COM port is already open by using one button dialog box. In the case as shown in the screenshot, no data would be coming to the program input and also, no error would be getting popped up if the port is already in use.

Could anyone please tell me how can I pop a message to the user if the port is already open without using any timeout logic?

I am using VISA Configure Serial port to take the com port input from the following diagram
