Re: Multiple Instances doesn't work in 3.2.2

I turned off the WiFi on my netbook and tried the UDP sharing, and it would not work. If I turn on the WiFi, it starts to work as soon as the DHCP server assigns an IP address. And then when I turn...

Re: Multiple Instances doesn't work in 3.2.2

Thanks for the link. I was not following that thread. It looks like what was discussed there is pretty much the same as what I've experienced. Repeatedly stopping and starting is pretty much what I...

Re: Multiple Instances doesn't work in 3.2.2

To follow up on my prior post, I've had problems for the past year getting two instances of O to pass data over UDP. I was using "localhost" in the address field with a port number of 10110. Usually...

Re: Multiple Instances doesn't work in 3.2.2

The answer to this is to set up as many portable instances as you want, and only run portable. Then you can launch in any order you want.

I still always launch my master first (the one that puts...

Re: Multiple Instances doesn't work in 3.2.2

The problem that I described above was a protection issue in the Windows Programs folder. Since then I have moved all the folders out into a non-protected area.

Your fix worked! I had entered...

Re: Multiple Instances doesn't work in 3.2.2

Dave,

I got busy sailing last summer and never actually had time to run Wireshark to diagnose this problem. I continued having problems getting the second instance of O to pick up the UDP data...

Re: Multiple Instances doesn't work in 3.2.2

Yes, makes sense. I'll look for Wireshark and take it down to the boat with me next chance I have.

Obviously I've used the NMEA debug window to confirm similar things, but it sounds like Wireshark...

Re: Multiple Instances doesn't work in 3.2.2

I now have portable mode configured, and each instance runs off its own independent .ini file that I can tweak to optimize my preferences for the left window vs. the right window.

However, I am...

Re: Multiple Instances doesn't work in 3.2.2

OK I figured it out. I had created my second OpenCPN folder in C:\Program Files (x86)\OpenCPN2 . I had forgotten that this folder is protected in Windows7, so OpenCPN was not able to write to...

Re: Multiple Instances doesn't work in 3.2.2

That is exactly what I did. But when I did so, OpenCPN exhibited the behavior I described above:



OpenCPN did load the settings from the .ini file that was in its folder, but it had to rescan...

Re: Multiple Instances doesn't work in 3.2.2

OK, to partially answer my prior question I now realize that if I move opencpn.ini from C:\ProgramData\opencpn to C:\Program Files (x86)\OpenCPN, then running portable mode with C:\Program Files...

Re: Multiple Instances doesn't work in 3.2.2

I must confess that I did some not-so-nice things to the opencpn.ini file to get two instances to work with different settings. Basically I created two different .ini files under different names, and...

Re: Multiple Instances doesn't work in 3.2.2

Thanks for the guidance. I realize that when you make these changes, there is usually a good reason for it. Now that I know that multiple instances does still work in portable mode, I will invest the...

Multiple Instances doesn't work in 3.2.2

I like to run two instances of OpenCPN side-by-side on my screen. One instance is zoomed in to see local features on the chart, the second instance is zoomed out to see AIS targets coming from far...
