how - bridge-mode woks? this is only screen or there is already a beta?

[Rudi De Vos]

Not offical, but files are online for certification testing:
- https://uvnc.eu/download/1710/UltraVNC_1710-dev.zip
- https://uvnc.eu/download/1710/UltraVNC_ ... _Setup.exe
- https://uvnc.eu/download/1710/UltraVNC_ ... _Setup.exe

Bridge works like our own P2P until we made but now we use a better library https://librats.com/, it make use of google servers instead of our own.

[Sainsuper]

I'm trying the bridge feature, but it doesn't seem to work. UltraVNC Viewer stays on this screen.


I know it's still an alpha feature but I think that from a graphical point of view the bridge code should be visible more clearly.

[Rudi De Vos]

You are correct... seems I broke something while updating the library

About the new file Copy options....
I am connecting to my work PC from home via an Anyconnect connection. I am using a 50 Mbps connection, which is not bad.
When I copy a file on my home PC, say the file: UltraVNC_1716_x64_Setup.exe, even if the copy/paste is for the local hard drive to a local flash drive, I get the message "Connection dropped, trying to reconnect." and my ultravnc connection fails then reconnects.
Am I supposed to be able to copy a file locally then paste the on the remote PC or vice versa? Should copying a file locally cause my UltraVNC connection to fail/reconnect?

[Rudi De Vos]

@ddbivens: Where you testing 1.7.1.6?

FT using copy/paste.

I tested both on LAN.
I using a 1.2 GB file.

File transfer: Do you get a popup with the filename and progress?

local CTRL+C and remote CTRL+V?
or
remote CTRL+C and local CTRL+V?
or
Both?

At the bottom, you can find some images:

testing on wan i noticed thet the ft updates seems to generate artifacts in the encoder...could it be that ?
viewer to server

IGNORE i was testing wityh an RDP session and forgot to disable the RDP clipboard... so i was actual seeing this.

[ddbivens]

Yes, I am using 1.7.1.6 on both ends.
I was able to copy one small file on the local PC using Ctrl-C, I waited a few minutes then I pasted the file using Ctrl-V on the remote PC and the file pasted to the remote PC.
I tried to copy a very large file on my local PC using Ctrl-C and immediately the UltraVNC window displayed: UltraVNC Viewer - Connection dropped, trying to reconnect (3) (Not Responding). After several minutes it started responding again. I tried to paste this file on the remote PC. However I was prompted asking if I wanted to replace the previous small file I had already pasted.
I tried again by selecting a small file again then two medium sized files and when I click on the UltraVNC window it either shows: UltraVNC Viewer - Connection dropped, trying to reconnect (3) (Not Responding) or the UltraVNC window shows gray on the bottom two thirds of the window. I was not able to get another file to paste in the remote PCs folder.
My biggest concern is that copying a large file when the UltraVNC Viewer is connected causes the connection to drop, even if my purpose is to copy/paste from a local drive to a local drive.

[Rudi De Vos]

I need to work as RDP.
CTRL+C just inform Server.
CTRL+V Server need to request Viewer to send file.
A progress dialog needs to show what's going on.

Not finished, redesiging...

[Rudi De Vos]

Don't get copy paste proper working.

Update FT window
-unicode support
-and unaccessible folder are red
