CodE Posted June 30, 2009 Report Share Posted June 30, 2009 Oh, I am the first to post here on the 'NEW' LAVA 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 Quote Link to comment
Eric Desbiens Posted June 30, 2009 Report Share Posted June 30, 2009 Many VISA functions or properties will return the error code -1073807246 if the ressource cannot be accessed (and will not wait for any timeout). Quote Link to comment
