Getting text from another program SendMessage? WM_GETTEXT

I am trying to get a large amount of text into my program, from a different program. I have tried using:

SendMessage progHWND, WM_GETTEXT, 8192, sText

The problem I am having, is the limit to the size of the text buffer. it's only letting me get a small portion of the text that I need. Is there a different method that will allow me to get much more? Or is there a way I can get portions of it at a time?

Thanks in advance.

Hi TAF2000,

Notice that there is a OS limitation in Edit Boxes. 0x7FFF for Win95/98/Me and 0x7FFFFFFF for WinNT/2000/XP

Good luck,
Jaime.

yes, the limt im having problems with is not max int (2147483647) that you refered too..
it is a much lower limitation caused by the string buffer:

Dim sText As String * 8192

it will not let you create a very large string..

so.. is there a way to get around this? using something else in the sendmessage command?

Thanks

zzzzzooc,
just saw your message after replying to jaime's comment. Will give it a shot.

Oh, one more comment. lngLen may need to be lngLen + 1:

If lngLen > 0 Then
lngLen = lngLen + 1
'etc...
End If
