I noticed that my component TElSSHLocalPortForwarding dont have ResolveDynamicForwardingAddresses property.

There´s some update that I need to make?

It seems that this property was added in the last 9.0.203 build or 9.1.204 beta. But it is not published so it is not visible if you put TElSSHLocalPortForwarding on a form.

Of course yes, if the IDE can't find the property. We provided the sample based on current code, and you are using older version of the code. Obviously we can't adjust code for each particular old version.

All you need to do is open the form in IDE and if asked about unknown property press Ignore button and the problem is solved.

Sincerely yours

I do not understand the problem: you were able to compile the demo with this property in the source code but the property does not exists? Have you modified the demo to compile it?

If you get an error please update your SBB version to the latest one.

Thank you for the demo and I must say it works great (though one minor problem)

This demo should be included with SSB if its not already.

The demo has a small flaw where if you close the app while connected the log() procedure is called after the lvLog component is destroyed, so there needs to be a simple check for this, such as

procedure TfrmMain.Log(const S : string; Error : boolean);
Item : TListItem;
if (csDestroying in ComponentState) then exit;

I've been using SBB for many years and I absolutely love it. My primary focus has been with the X509 and SFTP components, while not knowing very much about most of the other components and not having the time to tinker with them.

This demo combined with the amazing feature set and simplicity provided by the TElSSHLocalPortForwarding component really makes implementing a dynamic SSH tunnel a total piece of cake.

P.S. There is a slight problem with downloading the attachment from your post, in my web browser (Firefox) it opens the attachment and displays the content, rather than prompting for download, so it requires using the "Save link as" from the right-click menu, in addition the file is missing a file extension and firefox defaults to saving it with a .txt extension.

Thank you for your kind words. We are really glad that you are happy with the product and will do our best to continue to stick to the highest standards in future.

We will fix the sample and include the fix into the future SecureBlackbox update.

We will also try to resolve the attachment issue, however, I am not sure if it is easily resolvable. The forum was only designed to support picture attachments, and transient support for other file formats (which is closed now) was actually a sort of a 'hack' over its attachment engine.
