hi john
I have tested ne the new version 1.0.6.1 with new -sc_xx option.
-sc_xx prompt work only if winvnc running in user mode :
winvnc -sc_prompt -connect 192.168.0.x -run

If wivnc is installed as service or altready is open as user the -sc_xx option doesn' t work, so for UVNC SC helper option it works only if service option is 5.
I hope in rudi update!!!

In version UVNC 1.0.6.1 that changed, they now have 2 options for sc and the prompt option IS compatable with autoreconnect.

the thing about the GUI is that with the method below, i can "auto generate" the GUI instead of having it static, this allows me to save a little space, and make future development simple, we can improve it further as time goes on for sure

i think the embed data dialog is not that much important. in my case i won't modify the embed data every day. so i think if it is easier for you and the future development then do it.

Very great job JohnMC!

Little modification to do, in the host embed command, i'ld like to have entries with comma such as : [Lastname1, firstname1]ipadress1, [Lastname2, firstname2]ipadress2. But the program make an entries for each value separated by a comma!

Is it possible to disable the embed command ? I don't want people modify the exe file with the embed command and also discover techniciens ip adress.

Thanks a lot.

Hey John, if u can auto generate the menu then have it that way it still works well.

So John now we can have autoreconnect and prompt enabled at the same time? thats great!

dont know how ur coding works but perhaps have a ; to separate the connections? or if u can code it to ignore , inside the [ ]

Sainsuper sorry, i see i didnt read your question right, the sc option does only work in user mode, this is a limitation of uvnc, i do hope they can change this someday, for now these options are only usefull in user mode/non vista/7 system

kayman great thinking, i think ill opt to use the ; character, i dont see anyone using this character in the friendly name.

John,

I'ld like to have, for the default value of the drop down list, a first blank row or a tech name such "Please select a tech".

The goal of this is to oblige people to select a tech (or enter an ip adress) before pushing the connect button because i'm sure, that some people will push connect and the first tech in the list will receive false call!

I'll like to translate the UI in french. It don't have many words to translate but it would be difficult to follow new versions if i modify the current release. Do you plan to make language file to make easier translations ?

thanks again.

John, I have some good translation related functions already created for vnc2me and scprompt ... I will pm them to you tomorrow, to save re-inventing the wheel (or function - in this case).

pm me if you don't get them in about 12 hours (i only updated these functions on the weekend ... freaky ...)

your not telling me anything new there john ...

i re-wrote vnc2me about 5 times before coming to the code you can see now ... you need to make sure you use variables where ever you can (and HEAPS of them), this makes it a pain to read the source of (unless you wrote it or have alot of patience), but it makes the code ultimately more flexable (in my limited experience anyway) ...

oh, that and departmentalising your code (using file includes and functions) ... but i am just an amature ... so don't take my word for it ... take a look at the uvnc code ... functions galour, and variables galore ... (from what i can tell anyway :D )

i have forgotten to PM you the code ... will get onto that shorlty ...

Hello John. I would like to do polish translation of this SC port :) It has proven to be the best for me yet. And aptget function rocks!
Anyway - do You plan on using general lang pack like JDaus, or do You have a template of Your own?

Sorry to just jump in, but I've been reading through the forum and this seems very interesting to me. I am a computer support tech and am looking for a good remote solution. I am hoping to be able to remote in to my clients computer while I am away from my office. Will this do that? Seems I noticed something about a repeater being supported at some point. I suspect that is what I will need so that I don't have to rely a IP address forwarding at my end. If I am in a hotel or some other form of high speed internet where I do not have control over the router then I could not setup the needed forward. Let me know if your solution can do what I am looking for and if not, will it in the future? I am sure I am not the only one with this need. Thank you.

kayman...I'm guessing that on attempting to connect, uvnc_helper engages in a tussel with a third pary firewall and uvnc_helper looses the duke-out and crashes. It doesn't always happen, but I run a third party firewall that tussels with uvnc-helper once in a while, only in my case the firewall looses and is shut down with a similar error message.

This is an exceptional project, and I watch this thread in anticipation of further development.

At first i straight away thought it would be a firewall or antivirus problem but I had used older versions of the helper and it worked fine but anyhow I disabled unloaded the firewall / antivirus software (Trend Micro Office scan) and still had the same problem hence I thought to post, I'll try again with John's new beta release when its posted.

Beta Update

This update might become a release, i didnt want to go back to the 3.1 source to try and fix this crash problem so i worked on it in the 3.2 source, however this only has about half the features that i wanted for 3.2 but its something.

(7-08-09 - 3.1.0.36) Beta
-Fixed- Possible coruption in winvnc.exe from reshacking
-Added- Embed option "lock" to prevent editing of host/port 0=allow both 1=lock both 2=lock host only 3=lock port only
-Changed- Multiple host seperator character changed from "," to ";"
-Changed- Changed the way the embed option "site" works, it will now execute a command at the command prompt using the windows cmd.exe "start"
directive, if you specifiy a URL with a prefix thats properly set by your browser like "http://" then this will open it in that default browser
-Changed- New embed/settings dialog and backend.
-Added- Make URL option in embed dialog
-Added- "Save" option in embed window will only update the currenlty loaded settings (many changes are not noticable by doing this)
-Added- Ability to add a non selectable host list item by adding a friendly name with no value, ex: [Please Select A Tech];[John]192.168.0.1;[--Alternative Techs--];[Allyssa]host2.teammc.cc
-Note- Changes will only be available in the changelog available in the SRC zip, or online documentation

If you setup a UVNC repeater you could do this, you would follow the UVNC instructions regarding repeaters and when you setup my program you would use a host like this: "192.168.0.1 ID:1234" or if when you embed it if you want it to look nice "[John (Direct)]123.123.1.1,[John (Rep)]192.168.0.1 ID:1234"

Hi John,

Thank you for a great piece of software. I think I have found a bug which should be easily fixed.

Example steps to reproduce (in new beta):

1.Embed and save the following host string
"[Tech 1]anywhere:5501;[Tech 2]anywhere:5502"

2. Try to connect and you will see that it ignores the port given in the host string and instead uses the one in the port textbox.

Behaviour is the same both in the current release and the new beta.

Hello John...I've tried to PM you, but for whatever reason things have been stuck for the past few days in my outbox. So, I'll post my message here.

I've been following your development of UVNC HELPER for a while now. I'm quite impressed with the concept of your project. I tried your newest BETA today and find that I cannot enable encryption. When I look in the UVNC Helper temp directory I see that there are only six files there with the DSM plugin file missing. The key is there but no plugin.

I've tested your previous version with encryption enabled and have had great success. I've tried to enable encryption using the embed method as well as manually editing the ultravnc.ini file. Neither approach works for me.

I hope this bit of info is helpful to you. I look forward to the version that supports reconnect on restart. By the way, I like the new docking window.

I have a problem with encryption aswel - when trying to connect it says error getting protocol version.
Suggests problem with DSM plugin or encryption setup.
Currently tested with Viewer ver: 1.0.5.6 and 1.0.6.3

Thanks again John to integrate all my requests in the new beta.

I'll try it today.

I have another request but this one is not a functional item but more an aesthetic one.

With resolution of LCD, many people in our High school was using low resolution instead of native one. So, to get a better look and minimize eyestrain, we increase in the advanced display properties the resolution from 96DPI to 120dpi. When DPI are set to more than 96, your application will not increase button or text box size and for this reason the text will not fit them (text will be crop).

I know that is possible to get the dpi setting from the registry and do a ratio (such 120dpi/96dpi=1.25) to adjust the size of objects (windows, button, text input...)

Thanks.

Hello again John...Sorry about the confusion re PMs remaining in my inbox. I hadn't realized that they remain there until viewed by the recipient.

I've done some further testing with UVNC HELPER this AM. I manually copied the DSM plugin into the UVNC HELPER temp folder and an encrypted connection was made successfully. From that point on all was well. The only glitch I have been able to find is the inability to include the plugin when building the UVNC HELPER exe. Your project is coming along very nicely. I hope my observations are helpfull.

-Added- Embed option "embed" to protect the executable from accessing the embed screen
-Fixed- DSM file wasnt being packed with the executable because of tests i was conducting

Hi John,

Thank you for the advice on using the UVNC repeater. I will give it a try. Can you suggest an URL to point me in the right direction? I have found a couple things explaining how to set up the repeater, but they seem a little confusing. I will give them another look, but any advice/direction would be great. Also, thank you for putting so much time into such a great product. I can see you are helping a lot people accomplish what they need. I wish there were more people like you out there.

Release Update! See first post
3.1.5

This release was early due to not so simple problems with 3.1, it doesnt contain all the features i laned for 3.2 so the version is 3.1.5

Changes since beta2:
-Fixed- Description of the embed command
-Fixed- Error on connection when using 'lock' option
-Note- Using UVNC 1.0.6.3 (since 3.1.0.36)

Help files should be updated by the end of the day.

Xyhon thank you, this is now fixed.

BenCh i know of 2 versions of the repeater the one thats available on the downloads page and only runs in a console window, and a GUI one that i belive is older, im not sure how to configure the console version, if some one could explain this i would be thankfull.

CUI: http://prdownloads.sourceforge.net/ultr ... e?download
GUI: http://sourceforge.net/projects/ultravn ... e/download

if you use the GUI version then the directions should make sence at http://www.uvnc.com/addons/repeater.html

lamarmotte I really dont know how i would deal with this issue, ill do some testing, but i dont see it getting fixed too quick

kayman any update on your issue? im assuming its fixed

Now all I have to understand is how to password protect embed... As far as I know, I have to set password in uvnc.ini? And then write set embed pass "password"?
If You can provide me step-by-step I would be grateful.
Thanks
