%eb crashes during delay while processing cursor key input

Hi, (Ftn95 8.70, win xp/32)

I use a %eb as a mini editor. It works as as expected until I use the cursor keys cursor keys to move around the text. The cursor does not move for about 5 seconds for each keypress. i.e. 2 quick cursor move = 10 second wait. If try and use another editor function (i.e. exit) during this delay the program crashes. if i wait fro the cursor to move there is no issue. If I used the mouse to move the cursor around the text there is no issue .

I will try and test it on a win10/64 system to see if it a legacy issue

Here is the %eb call with options and some of the trace back message

CHARACTER*(32767) EQN_MODEL_BUFF_X

IWIN = WINIO@('%~`*.*eb[vscrollbar,hscrollbar,undo]&', IWIDTH, + IHEIGHT, EQN_MODEL_BUFF_X, EQN_BUFF_SIZE, + ED_INFO(EDI_DATA_EXIST_GREYED), EDIT_INFO_EQN)

Can you provide a small working program that illustrates the failure?

Hi Paul

I will try to make smaller/simpler version and experiment on different platforms

I will let you know how i get on

thanks

steve

Paul

this code demonstrates the problem. if you add text( inc cr/lf) in the middle of the numbers and then navigate using the cursor keys the response freezes and then the program crashes when closed (ftn95 ed_test.for /lgo/win) happy hunting

 PROGRAM EB_TEST

  EQN_MODEL_BUFF_X = '1234567890 1234567890 1234567890' // CHAR(0)
  IWIN = WINIO@('%ca@&amp;', 'model sheet')
  EQN_BUFF_SIZE = LEN(EQN_MODEL_BUFF_X)
  IWIN = WINIO@('%`*.*eb[vscrollbar,hscrollbar,undo]&amp;', IWIDTH,

  IWIN = WINIO@('%ff')
  END

This issue has now been fixed for the next release of ClearWin+.

The failure is in new code for handling UTF8 characters and these are not used in this code.

The failure when actually using UTF8 characters remains to be resolved.

Paul

It works fin with the development DLLs

Thanks for the quick response

Steve, Paul,

I guess to have a similar/same problem. We supplied our most prominent DimBo(R) software to Japan. On our clients' computer the program terminates from time to time with the following exception:

The instruction at address 10040051 attemped to read from location 00000128

10040027 backup_one_utf8_char (<ref>(<ptr>char))#70 [+002a] 100408a9 store_position_hint ...

Unfortunately all input is lost since last 'save' instruction.

Can you advise how to resolve this on developer's or user's level?

Thomas

Have you tried using the latest DLLs from here...

https://forums.silverfrost.com/Forum/Topic/3780

Paul,

Tthe salflibc.dll installed on our clients' computers is version 23.1.4.9.

Do you believe that the problem will no longer occur with version 23.6.18.18?

Thomas

To the best of my knowledge it should be OK with the latest version.
