Will there be an update to UVNC SC

Postby peon2t » 2016-02-01 13:44

Hello

I'm using UVNC SC for many years now - but especially since the release of Windows 8.1 an Windows 10 the problems seem to get worse.

A very common issue is, that UVNC only refreshes a certain amount of the top left side of the screen, while the bottom and the right side can only be refreshed manually. This happens on the majority of the servers that run Win 8.1 or Win 10.

Also the performance isn't as good as one would wish. Especially if there are images involved (e.g. on Websites that are displayed on the servers screen) remote control often gets nearly unuseable. It doesn't really seem to matter how good the upstream connection from the server is, so I assume it isn't a problem of how the data is transfered but rather how it is captured.


Of course I'm aware that uVNC SC is a non-commercial product and that you can't expect it to fully compete with it's commercial competitors but I was still wondering if there will be any attempts to make uVNC SC compatible again to the software and hardware that is "out there" nowadays or if it's development has been completely abandoned?

What version are you using?
Isn't the win8/win10 update working ?

Hello Rudi,

I'm also a little bit confuse about SC, The only version I found is 1.1.0.0, is it the latest ?. If so my test reveal that the screen refresh is very slow. If I use vncserver (complete version) on the same computer that was running SC and connect to it, the screen refresh is pretty fast . If I used SC on the same computer and connect to the vncviewer the scrren refresh takes about 5 to 10 seconds on each click before viewing somewthing on the vncviewer computer ?. I tried on Windows 7 -> Windows 7 computer and Windows 10-> Windows 7 computer same problem !

Best REgards,

Sylvain

Hi,
I tried to extend Dtwinver.cpp with
Code: Select all
BOOL COSVersion::IsWindowsWin8(LPOS_VERSION_INFO lpVersionInformation)
{
  return (lpVersionInformation->UnderlyingPlatform == WindowsNT &&
          lpVersionInformation->dwUnderlyingMajorVersion == 6 &&
          lpVersionInformation->dwUnderlyingMinorVersion == 2);
}

BOOL COSVersion::IsWindowsWin81(LPOS_VERSION_INFO lpVersionInformation)
{
  return (lpVersionInformation->UnderlyingPlatform == WindowsNT &&
          lpVersionInformation->dwUnderlyingMajorVersion == 6 &&
          lpVersionInformation->dwUnderlyingMinorVersion == 3);
}

BOOL COSVersion::IsWindowsWin10(LPOS_VERSION_INFO lpVersionInformation)
{
  return (lpVersionInformation->UnderlyingPlatform == WindowsNT &&
          lpVersionInformation->dwUnderlyingMajorVersion == 10);
}

and related changes in Dtwinver.h and Test.cpp to recognize newer Windows versions. It doesn't work, but I'm not so familiar with C and I don't know, what's wrong. Windows 8.1 is not recognized. (BTW: A Windows Server 2008R2 is shown as "Vista"). Although it is nothing important, I'd like to see, how you would do that.

Everything is ok now, it was my fault I wasn't understanding the process to create my SC version now it's ok and working fast !

Thank you Rudi,

Now where can I read about the distribution of the EXE received, I want to incorporate it in our software for our technical support staff to give them the ability to control the remote computer !?. I'll also review your uvnc2me wich seem interesting to !.

The received exe is a 7zip sfx file, if 7zip is installed you can extract it in see what's in the exe.
Source of the exe can also be downloaded on the same page.

Thank you. I read, tried to understand and change test.cpp for a while, but the differences of the new dtwinver-files are too big for me. I give up and stay without seeing the correct OS as before. :-/
