Dear team,

First thank for this awesome tool.

I have an issue when trying to remotely connect to a VNC server on a Lexmark printer.

VncSharp raise the following exception:

System.Exception : 'Invalid subencoding value' in "ZlreRectangle.cs" line 52

var subencoding = rfb.ZrleReader.ReadByte();

if (subencoding >= 17 && subencoding <= 127 || subencoding == 129)
throw new Exception("Invalid subencoding value");

subencoding value is 34 in my case.

Remote form stay black and nothing happen.

Any idea why could cause this behavior ?

rfb.ReadFramebufferUpdateRectHeader(out Rectangle rectangle, out int enc);

// Build a derived EncodedRectangle type and pull-down all the pixel info
var er = factory.Build(rectangle, enc);

i've just downloaded the project and launched with visual studio this is what i get:

The example works, but my code doesn't?

Any help would be greatly appreciated!

Hi, thanks for this great library. I am looking for a vnc library that can be used in a closed source project. So will there ever be a chance that the license of the VncSharp library will be changed to a less restrictive one, like LGPL, BSD or MIT?

Hi,
If everything is good, and VNC is showing remote panel, but if I then disconnect the ethernet cable, it takes very long time, before the .ConnectionLost event raises. ~15 sec.
Is it possible to set a timeout to a shorter period ~2 seconds..?
Someone with same problem..?

VNCSharp does not support UltraVNC's repeater functionality.

Fun part: I made it and it works as a proof-of-concept. Just a little bit more work and it's production ready. How do I get that in?

When I tried to connect to VNC server( Windows version 6.4.0), I got the error dialog, saying "Unable to connect to the server. Error was: Only versions 3.3, 3.7, and 3.8 of the RFB Ptotocol are supported..
Check that a VNC host is running there."

Can anyone help? Thanks a lot.

The latest RealVNC server is advertising version 4.001. I've had success by modifying ReadProtocolVersion to detect this and setting verMajor to 3 and verMinor to 8.

If we run multiple vnc sessions on the linux server,
we need to connect that host as hostname:1
But our lib failed to do that

how to change it to arrow?

I'am using VncSharp to connect to my mac. Since a few years Apple has implemented a login screen to select which user to log on. This screen loads, but after I enter my passwort I get a disconnect event. I traced the error in the code and found the following error:

Index was outside the bounds of the array
VncSharp.Framebuffer.set_Item(Int32 index, Int32 value) in d:\Sourcesafe\RDPConsoleWpf\VncSharp\Framebuffer.cs:Zeile 71.
VncSharp.Encodings.EncodedRectangle.FillRectangle(Rectangle rect) in d:\Sourcesafe\RDPConsoleWpf\VncSharp\Encodings\EncodedRectangle.cs:Zeile 186.
VncSharp.Encodings.ZrleRectangle.Decode() in d:\Sourcesafe\RDPConsoleWpf\VncSharp\Encodings\ZrleRectangle.cs:Zeile 72.
VncSharp.VncClient.GetRfbUpdates() in d:\Sourcesafe\RDPConsoleWpf\VncSharp\VncClient.cs:Zeile 394.

Maybe this error occurse because after the login screen the screen size is adusted to the desktop size. Could you please fix this error?

hi,

when i connect with my VncSharp client to my UltraVNC Server white boxes popping up on client.

hello
i used the VncSharp controll for remote to users Desktop, but as i test the code i can see the User Event as cascade Form ! i don't want to see Event like cascading form!

Or how can i kill previous Remote control form?

I am having trouble trying to figure out how to change its color display. So if it connects to a viewer I can tell it to connect in 8 bit or 16 bit. I have tried adjusting the RGB but it really did not work.

Any help would be great to achomplish this. I want to use this viewer over low bandwidth.

It has error on sending UTF-8 character such as Arabic and Persian character. How can we fix it? Is it support UTF-8?
