I did not realize that the "SELECTION" property has a 64k limit.

I use an Editbox to display information. Definately could exceed 64k. I also have an option to "FIND" and "FIND NEXT" text within the Editbox. Was using the "SELECTION" property to highlight the found text. I just found out that it does not work beyond 64k.

This is kinda an annoyance.

Richard,

Anything special about the editbox properties? I don't seem to be able to reproduce this…

Sprezzatura,

Could you do me a favor and test this little proceedure… FOCUS being the editbox.

TEXT=STR('1',80000):'INDEX222'

RESULT=SET_PROPERTY(FOCUS,'TEXT',TEXT)

RESULT=SET_PROPERTY(FOCUS,'SELECTION',80001:@FM:5)

SELECTION=GET_PROPERTY(FOCUS,'SELECTION')

The "SET_PROPERTY" works fine. It actually does select the letters "INDEX", and only the letters index. Its the "GET_PROPERTY" that is failing for me. The "SELECTION" variable contains the following…

65536:@FM:0

The styles I have checked for the editbox are LEFT, VISIBLE, BORDER, HORZ SCROLL BAR, VERT SCROLL BAR.

I used the "LOSTFOCUS" of an editline to execute the proceedure. When the editbox got focus the selection showed up just fine. My problem is I can not get "SELECTION" position beyond 64k.

Aha! Now I see what you mean - the text does get selected, but the SELECTION property returned is screwed. OK, that looks pretty much like a bug to me :)

Here's a quick workaround though…
declare function getPointer, sendMessage
equ EM_GETSEL$ to 0x00B0

hwnd=get_Property( focus, "HANDLE" )
selStart=0
selEnd=0

retVal=sendMessage( hwnd, EM_GETSEL$, getPointer( selStart ), getPointer( selEnd ) )

* // Remember WinAPI stuff is 0-based ...
selStart += 1
selEnd += 1

I happened to have realized this issue just last week, and had already fixed it for the next major version of OI.
