ICE

When is the best time to do things like:
   set terminal type
   set color mapping flag
   set colors
   set key maps
   etc.
Right after issuing the Connect method
or
While processing the OnConnectionComplete event.

I noticed that some things, like set terminal type, can only be done after a connection is established so I do all setups after a connection is established.  Maybe some items can be setup before the connection is established.

I'll check into that in more detail, however it's important to note that some things that are passed on connection, most importantly the terminal type, so the remote host has no way to know if you have changed the terminal type AFTER you have a connection. Some versions of Unix can properly respond to a lines/columns change after connection but this is not universal.

Changing things that are only cosmetic, like the color attributes is fine to do after the connection is established.

Additional information:
1. A disconnect - connect cycle will restore the Caps Lock synchronicity.
2. Even when synchronized, with the Caps Lock on and holding down the shift key, pressing the letter keys gives upper case letters instead of lower case letters.

For Example.
1. Bring focus to the OCX control.
2. Connect to a host.
3. Press the Caps Lock key to turn ON the Caps Lock light on the keyboard.
4. Notice that pressing the letter keys gives upper case letters.
5. Move focus away from the application with the OCX control, like to the desk top.
6. Press the Caps Lock key to turn OFF the Caps Lock light on the keyboard.
7. Bring focus back to the OCX control.
8. Notice that pressing the letter keys continues to give upper case letters.
9. Press the Caps Lock key to turn ON the Caps Lock light on the keyboard.
10. Notice that pressing the letter keys now to gives lower case letters with the Caps Lock Light on.
11. Telnet Pro does not misbehave this way.

Has anyone else seen this or can it be something in my application?

Telnet Pro saves the state of the "shift" keys (shift, alt, caps-lock and control) internally. When regaining focus from outside, it rereads the state of those keys and resyncs the internal copy. I'm not sure how you would handle that in your app. I THINK if you do a SetScanCodeMode(true) then ScanCodeMode(false) it will clear the internal flags but then I think you'd have to do the same for windows at the same time.

The SetScanCodeMode procedure didn't resync the Caps Lock but you sent me in the correct direction.  In the windows event OnActivate I use the GetKeyState and SendInput to remember and restore the key states.
Thanks.
Also, both the OCX and Telnet Pro have the equivalent problem with the SHIFT key.  In Pro, press and hold the SHIFT key, use the mouse to move focus to the desk top, release the SHIFT key, return focus to Pro and Pro thinks the SHIFT key is still pressed.  I don't know why anyone would do that but it is interesting.

Excellent, Thanks for the feedback!

ESP!  Just this morning I thought about getting online and checking for updates.  I can't wait to try the TraceViewer.  Thanks.

My debug OCX is dated 07/13/2000 and I never could get it to register anyway.  I have a question but I am not sure if it should be a new thread.
1.  I see that version 5.1.21 fixed the sync problem with the Shift Key and the Caps Lock Key.  Now I need a way for my program to discover the version number of the OCX because my program shouldn't attempt to synchronize these keys for version 5.1.21.
2. A feature of my program that does "GetScreenContents", changes the color attributes, and then does "SetScreenContents", no longer functions with version 5.1.21.
So my question is: How do I obtain the version information from the OCX?

This question is about setting colors via GetScreenContent and SetScreenContent.
Reference your documentation at figure 1.7 on page 24 which shows all possible combinations of background and foreground colors.  The background colors (and foreground colors) look as expected for rows 0 thru 7 and rows 10 thru 15. Rows 8 and 9, which are background color index values 8 and 9, do not have a uniform background color like the other rows.
If I set the attributes to 9F for white letters on a blue background the screen actually shows white letters on a teal background and a GetScreenContents shows the attributes to be 3F which is correct for the color displayed but it is not the 9F that I set.
Using SetColor works properly and all new text display as expected.
Are there any special rules for the background color index values of 8 and 9 when setting attributes via SetScreenContents?
