Connection Options

Post by y30 »

Hello,
Been using SC for a bit and have been very pleased. Thanks for the great work!

Just a quick question:

Is there a way to set the default Connection Options, specifically, setting the number of colors to 64 so that whenever a client connects, I don't have to manually change the color number every time?

Thanks and keep up the great work!

Have you tried "vncviewer -?"

Post by JSanchez »

If you try "vncviewer.exe -?" (without quotes, and from the UltraVNC folder) you will get a list of the available switches. Although I have to say that I tried it and it didn't work...it still defaulted to the "Full color" support. :(

I wonder if it can be done through the server? Although I didn't see any switches for changing the color depth on the winvnc.exe (server side) of UltraVNC, which leads me to guess that it would be the same for the SC version.

P.S. Found some of the parameters that can be passed to the server side of SC.

Code: Select all

-service
-servicehelper
-run
-install
-sinstall
-remove
-reinstall
-settings
-defaultsettings
-about
-kill
-connect
-multi
-fus
-autoreconnect
-id
-plugin
-password
-noregistry
-notrayicon
-readonly
-username
Some of them are pretty self explanatory, but others aren't. I'll see if I can dig a list of what/how we can use them (for example, the "-settings" one)

Ah! I missed the /noauto switch. I did try the /64colors and even the /256colors switches and it didn't make a difference. Although I have to say that UltraVNC, even with it's automatic settings is pretty fast. I was able to have my sister connect from her home to my viewer and the speed was good enough for me.

Thanks for the input redge!

Well, they were found within the winvnc found within the SC executable created online. I just used WinRAR to open the self-extracting archive and then ran strings.exe. So they're in there, but not enabled? Oh well, it was interesting to see the /autoreconnect switch. But then I've read posts from the author of SC and he mentioned that due to his employer's policies, he cannot create an autoconnecting program (or at least, that's what I understood)

Anyway, once again, thanks for the feedback redge!

applicable only for 32 bit display adapter
Set your Control panel... display ... tab Settings... Color quality
select highest (32bit) (nor 24 bits)

then your vncviewer convert to 8 bits colors and you can see the new 64 colors.

known limitation:
if your card support only 24 bit colors, like Intel Graphic 865 chipset onboard., you have no luck.
