Some properties are missing int the documentation

The following properties and methods are missing in the documentation:

connectionBar

Methods:

getBytesSent

GetScreenBitmapScaled

showConnectionInfo

Conneced property set too early

carsten — Wed, 09 Dec 2009 14:47:38 GMT

The Connected property is not synchronous with the Connected-Event and the getConnectionState code. It seems that is is already set to true, when the getConnectionState begins "CONNECTING".

I think it should be: getConnectionState=CONNECTED if only if connected=true.

Incorrect Display v 2.9.6.3

xDavidD — Tue, 11 Aug 2009 00:42:33 GMT

The version 2.9.6.3 gas many display errors when switching view types on the server.
(UltraVNC 1.0.6.4). Many graphic elements are only partly updated, or not at all.
Using the version 2.9.6.0, this behavior is not seen.

The server side uses quite a high resolution, ( 1920 x 1200). The mirror driver and system hook DLLs are enabled to allow the correct display of GDI and WPF elements in the software.

Problems with ProxyType

skafoelix — Mon, 29 Jun 2009 07:32:35 GMT

Hi!

I currently have a problem with the ProxyType parameter of ViewerX.
Whenever I'm trying to set a Proxy Type with password (VPT_SOCKS5_USRPWD or VPT_HTTP_BASIC) I get a ArgumentException "Value does not fall within the expected range.".

I'm using the latest version (2.9.6.1) and .NET 2.0.
All other proxy types seem to work, at least I don't get an exception when setting the property.
I've also tried setting the username & password properties before setting ProxyType but that doesn't help.

regards,
felix deimel

When in stretch mode, moving the cursor around, or moving a window of the server is leaving traces on the screen, that disapear after a refresh.

ViewerX Crash when idle

kevinc — Fri, 23 Nov 2007 05:08:23 GMT

Hi

I've written a quality control application which is running in Access 2003 and I've used the ViewerX Active X plugin to view the screen and the person you are quality monitoring.

I'm being told that after 3 or 4 minutes of not using the system but leaving the viewer open, that is freezes up and ultimately will need to be restarted.

What seems to happen is that Access starts to use up tons and memory until it falls over. It doesn't do this if you do not engage the Viewer so it must be down to this.

I've tried running it in ZLIB mode and this made no difference.

I've tried using the highest levels of compression and this makes no difference.

Any suggestions?

Blank object in multi user environment

kevinc — Tue, 13 May 2008 01:32:18 GMT

Hi

I'm using your ActiveX in an Access program and since registering the product I'm finding that the viewer is only working on one computer at a time.

I've installed the ActiveX and put in the license as per your instructions on every PC.

Essentially what seems to be happening is that when I put the newest version of the control on the form, this control was "bound" to my PC. The other users then complained that it didn't work for them (just a blank box not a control) and I then used their PC to reset up the app.

I then get a call from another user saying they've got the same problem and I check myself and yep, no control??

Any suggestions?

registering the ViewerX DLL in Win98

marc — Thu, 08 May 2008 06:07:32 GMT

Hi,

I 'm trying to use the ViewerX in a small test application.

Installing on a WinXP works perfect,

but on Win98, after installing the downloaded setup, the activeX component still isn't known.

Also, manually registering it with "regsvr32 scvncctrl.dll" gives the error message:

LoadLibrary("scvncctrl.dll") failed. GetLastError returns 0x0000001f.

(tried on 2 different machines)

Any idea ?

Problem with flash animations

daniele.ciattaglia — Tue, 06 Nov 2007 04:00:00 GMT

Hi,

i'm using smartcode vnc client and server components to develop a remote control of my application.
This is my problem:

if i control a page of my application without flash animations inside, everything goes fine.
But if i put a flash animation inside my app, after about 3 minutes the client stop to refresh images.

Why?
i can't remove the flash animations from my app.

it may depends from the compression method?
thank you

Daniel

Dynamically Created Viewer requires license file

Airegin — Mon, 20 Aug 2007 14:43:21 GMT

Doing something like this will cause the licensing popup window to pop up on user machines. The only way I've found to get around it is to deploy the .lic file with with. What is the correct way to handle this?

(VB.NET 2005)

[code]dim objVNC = New AxViewerX.AxCSC_ViewerXControl

Me.PanelMain.Controls.Add(objVNC)[/code]

I can send a demo project and binaries if that helps..

ViewerX.ScreenStretchMode.SSM_ASPECT not implemented

Carl916 — Tue, 22 May 2007 12:06:34 GMT

Please find attached a screenshot of the exception.

VNC ViewerX crashes??

erix — Mon, 22 Jan 2007 05:24:49 GMT

Using ViewerX version 2.7.7.1 and a RealVNC server, the ViewerX component crashes the program.

It seems that the more data transferred the sooner the crash happens. Stretched or none stretched mode does not have any effect.. both modes crash after a while.

The application I'm using testing is the C# sample without modifications. (well I fixed the encoding to ZRLE)

The application running on the server PC which we need to monitor has a couple of GIF-animations running, which gives datarates of approximately 700 bytes/sec with ZRLE encoding. At this rate the crash happens at about 5-7 minutes. And a lot later if these GIF-animations are disabled.

I tried to add an button to the sample.. with which I call the Refresh - method.. This method actually still works and the Viewer is really updated. The communication also works.. The GetBytesReceived keeps reporting more bytes received even after the screen updating is stopped.

When the Viewer stops updating.. I cannot move the application or minimize/maximize, i.e. anything that could trig a screen-update, will make the application crash immediately.. without any notice actually..

Any Ideas??

I saw there was a similar post in VNC manager bug report.. But I'm not sure that this was really helpful..

Keyboard Problem

Paesmans — Thu, 09 Mar 2006 07:42:23 GMT

We are trying to integrate ViewerX inside a Delphi application.

We have tried to do in in 2 ways, everything works fine but in both cases, no keyboard events are passed to the NVC Client.

The same in VC++ works fine but we can't use that solution.

-We have embeded the ActiveX in a Delphi Form. No Keyboard

-We have an embeded IE inside our application. We have an html page that works in IE directly but when the IE in embeded in our application, no Keyboard events. We have no problem when embedding ThightVNC Java applet in the same conditions.

Any pointer or solutions?

Thanks.

Vincent.
