ICE

1. Lets make sure the OCX programmer has plenty to do when he returns.

2. Item 2 above appears to only be an NT issue.  Caps lock resyncs properly under all conditions with XP and 2K.  Who needs NT anyway?

3. I don't think I have the "topmost BG (high intensity)" problem but I do have a problem with foreground color.  If I do SetColor (1,n) with n between 8 and F, a GetColor(1) returns n, but new characters on the screen display as if I had done SetColor (1,n-8).  I see that TelnetPro does not have this problem.

4. If I mistakenly do SetColor (1,0) and SetColor (2,0) - black letters on a black background - a GetScreenContents(...) returns garbage.

5. I develop on an NT but the operators run the application on XPs and 2Ks. We use the ICE 437 font with the application.  All our PCs are now at 5.1.21 so I can't determine if an issue is old or new.

6. Have a nice weekend.

I did the following and there was no improvement or change in performance: I restored 5.1.19 OCX; I rebuilt the "dejavu wrapper" - dejavu.cpp, dejavu.h, font.cpp, font.h - from 5.1.21 because mine where nearly two years old; Tried static and dynamic linking of the MFC dlls.  I did these test on my NT and on a 2K (the compile was done on the NT) that I use for testing.

I develop on a NT using MS Visual C++ 6.0.  The application is used in production on XPs and 2Ks.

Any estimate about when I will get a reply?
(If it helps, we are scheduled to buy 60 additional licenses this month.)

In summary, the two hot questions are:
1. How do I make SetColor(ID,Value) work with Values between 8 and F?
2. When is the best time to do things like:
    set color mapping flag
    set colors
    set key maps
    etc.
 a:Before issuing the Connect.
 b:While processing the OnConnectionComplete event.
 c:After issuing the Connect.

1. Terminal type is 2 - ANSI (25 Line).  At OnConnectionComplete: the terminal type is set, the colors are set (with bright foreground), the screen is re-written.  At that point the J.River copyright is on the screen in bright letters.  Then the text that arrives from the host is in dim letters.

2. Thanks - great info.  I never considered changing the color info in the default profile.  Our application extracts key mapping information from a user profile and passes it on to the OCX during OnConnectionComplete.  That lets us use your profile editor to setup key mappings.  Do you guys publish the exact structure of a profile?

Thanks again.  I have a few things to try.

1. Changes to the default profile are not reflected in applications using the OCX.  I just thought about rebooting - maybe the OCX only reads the default profile once.

2. Using the code below that swaps the ColorEntryTerminal makes Dejavu ANSI terminal emulation behave like other emulators that my users seem to like.

Thanks.


// long l0 = m_ac1.GetColorTableEntry (0);
   long l1 = m_ac1.GetColorTableEntry (1);
   long l2 = m_ac1.GetColorTableEntry (2);
   long l3 = m_ac1.GetColorTableEntry (3);
   long l4 = m_ac1.GetColorTableEntry (4);
   long l5 = m_ac1.GetColorTableEntry (5);
   long l6 = m_ac1.GetColorTableEntry (6);
   long l7 = m_ac1.GetColorTableEntry (7);
// m_ac1.SetColorTableEntry (0, m_ac1.GetColorTableEntry ( );
   m_ac1.SetColorTableEntry (1, m_ac1.GetColorTableEntry ( 9));
   m_ac1.SetColorTableEntry (2, m_ac1.GetColorTableEntry (10));
   m_ac1.SetColorTableEntry (3, m_ac1.GetColorTableEntry (11));
   m_ac1.SetColorTableEntry (4, m_ac1.GetColorTableEntry (12));
   m_ac1.SetColorTableEntry (5, m_ac1.GetColorTableEntry (13));
   m_ac1.SetColorTableEntry (6, m_ac1.GetColorTableEntry (14));
// m_ac1.SetColorTableEntry (7, m_ac1.GetColorTableEntry (15));
// m_ac1.SetColorTableEntry ( 8, l0);
   m_ac1.SetColorTableEntry ( 9, l1);
   m_ac1.SetColorTableEntry (10, l2);
   m_ac1.SetColorTableEntry (11, l3);
   m_ac1.SetColorTableEntry (12, l4);
   m_ac1.SetColorTableEntry (13, l5);
   m_ac1.SetColorTableEntry (14, l6);
// m_ac1.SetColorTableEntry (15, l7);

Before the change the application displayed all text as dim letters no matter how the colors are set.  After changing the color table the application displays text as bright and dim letters as it does in other emulators.  Makes my users happy.

This file contains the struct's and functions used to construct the profile variant that is used in the connect function (2nd parameter).
Theoretically you should be able to get the profile, change the terminal type and set the profile before calling the connect.
