UltraVNC

Hi,

Older versions did it too, like 1.2.2.4. It seems very sensative.

Hi Rudi,

We have a problems that the vncviewer 1.2.3.0 is constantly disconnecting and reconnecting. We have some pretty slow connections. Is there criteria that can be changed to decide when to disconnect?

Polling Failsafe:
Fantastic, will test on Wednesday.

Black screen with no monitor:
We also found that the graphic card driver from NVIDIA has the possibility to make a virtual monitor (EDID). Tested it on Friday and it works.

Maybe, the other cards have this possibility too.

We found that going back to an older display driver fixes it sometimes.

Thanks Nanobot for the suggestion.

Rudi, can you then at least switch over to polling if directx fails?

Hi Rudi, After making a closer review, I find that in Image ‚Windows 10 LTSB 2016‘ (based on Windows 10 Enterprise 1607) winvnc works without a monitor, but in 'Long Term Servicing Channel‘-Version ‚Windows 10 LTSC 2019‘ (based on Windows Enterprise 1809) winvnc does not work any longer without a mon ...

ok, thanks, but my biggest problem right now is the black screen when no monitor is attached by win 10. These are the same computers, just running win 10 now, and it worked with win 7. This is really important, without it, we can't use winvnc. Can you provide a debug ddengine dll so we can see if it ...

Do you have a recent debug version I can use and see what is happening?

Does winvnc require that the computer has a monitor?

I have tried, but without a monitor the latest winvnc and 1.2.2.4 show only black under win 10.

Hi Rudi, Currently in win 10 as service, winvnc is doing a check for UAC (registry SoftwareSASGeneration) which it not present, but the Service still Shows Login page and I can log in no Problem. - First Problem, Server brings a Dialog on Screen that no Body can see, and doesn't do anything more ...

ok, so using the above function, set the Event names like this. I have tested and it works, should I check it in? winvnc.cpp void SetEventNames() { DWORD ppid = GetParentWinVNCPID(); if (!ppid) { ppid = GetCurrentProcessId(); } sprintf(g_szGlbSessEvt, "Global\\SessionEvent_%d", ppid); sprintf(g ...

I have a function that I wrote to get the parent winvnc.exe pid that we could use to create all the global event names for Services. The Service could CreateEvent names with it's PID and the children would also create the global Event names from the parent pid, and both parent and child can use ...

ok, well then it Needs more in the Name "Global\\SessionEventUltra", so that it and the process that it creates get monitored and not all instances of winvnc Server.

Hi Rudi, The new function wait_for_existing_process(); in service.cpp monitor_sessions_RDP hangs when more than one winvnc Service is running. I commented it out and everything runs as before. Do we need this function? What purpose does it provide? Is there a Chance that the "Global ...

Sounds to me like a threading problem.

This has already been fixed in 1.2.2.4, I hope

r1191 - Mirror driver button correct with Win 7 and uvnc_settings

You can find the zipped exe (win7/10 x64) at http://www.resource-solutions.de/ultra/winvnc.zi_p for revision 1189.

Mouse position fixed in r1189

Could you please describe your setup? Especially in terms of main monitor, second monitor positioning.

I have not uploaded a viewer, but I guess I can until Rudi has the chance to make a new official version.

File from http://www.resource-solutions.de/ultra/vncviewer.zi_p for r1179

auto size problem fixed in r1179

Ok, I can reproduce it. If you move any of the sides, after Auto size, then it shrinks to the correct size.

@Lucent, maybe I missed it, but could you explain your scaling bug and how to reproduce it?

@Lucent, please try the exe from the zip.

@Rudi, the date of the winvnc.exe in the zip is from 2018-10-31, it couldn't have had r1178.

@Lucent and Skyfighter, can you test with Rudi's build, thanks?

Ok, fixed in r1178

You can find the zipped exe (win7/10 x64) at http://www.resource-solutions.de/ultra/winvnc.zi_p for revision 1178.

Fantastic, great to hear it works!

Yes, I will look. I think the zip files are done so the transfer is smaller, but not if the wrong files get zipped.

OK, now I got it!

You can find the zipped exe (win7/10 x64) at http://www.resource-solutions.de/ultra/winvnc.zi_p for revision 1177.

Skyfighter, please test.
