Title: unselecting "make single instance application" cases application to not compile.
Post by: Lupo on July 25, 2021, 03:37:18 PM

Hello,

I have built 2 HMIs, one for the remote unit (raspberry pi) and one for the main unit (windows).  They both work great.  I now need to make the windows PC to open more than one instance of the HMI.  A forum post said all i need to do is the action in the subjct line.  When I do that, the compile faults out and i get this message:

Severity   Code   Description   Project   File   Line   Suppression State
Error   BC30456   'MainForm' is not a member of 'MfgControl.AdvancedHMI'.   AdvancedHMI   C:\BeerDispenserServer\AdvancedHMI\AdvancedHMI\My Project\Application.Designer.vb   35   Active

In fact, if I use a working backup and unselect and select the box again before compiling, I still gets the same fault.

Any ideas?

I could also use a single instance application if i could figure outhow to change the IP address in the communication driver from the HMI but I haven't figured that out.

Thanks for any thoughts.

Thanks, but it didn't help.  This is so weird.  I'm open to any other ideas.

Any time I make any change at all to the Application properties of AdvancedHMI (using the form) the auto generated vb throws this fault.

It's got to be something simple....

Was something simple.  Where is says MainForm it should of said the name of my actual mainform.  I don't know it got changed, but it works now.  It's a wonder how a vacation can give you some clarity.
