Hi Tomaz,
Thanx for your reply. I know, sorry, it's not really clear (my poor english
maybe:-)
My external application has a window. Empty. On that window (not my
application), I can create a TMemo using shortcuts (ctrl+shift+A). In that
TMemo, I have to write some datas from a record (about 10 fields, so 10
Memos to create at runtime). So, I copy one field on the clipboard through a
TStringList:
Memo2.SelectAll;
Memo2.CopyToClipBoard;
Then I create the Memo.
I use:
DownKey(VK_CONTROL);
DownKey(VK_SHIFT);
DownKey(Ord('A'));
UpKey(Ord('A'));
UpKey(VK_SHIFT);
UpKey(VK_CONTROL);
Upkey, DownKey procedure :
procedure DownKey(K: Integer);
begin
keybd_event(K, MapVirtualkey(K, 0), 0, 0);
end;
procedure UpKey(K: Integer);
begin
keybd_event(K, MapVirtualkey(K, 0), KEYEVENTF_KEYUP, 0);
end;
After that, my TMemo is created (Memo1). My datas are on the clipboard. I
use wm_paste to... paste the datas in the new created Memo1.
It quite always works. But sometimes not. If the datas to paste are too
big, my program goes on, creates a new Memo (Memo2), and the datas are
pasted in Memo2, not in Memo1.
What I want (would like) :
- copy the first field on the clipboard
- create Memo1 in the external application using shortcuts
- paste the datas from the clipboard in Memo2
- wait until its done --> that's my problem : now, I use a sleep (400), and
I don't like this QAD solution
- copy the next field on the clipboard
-create Memo2
- paste the next datas
- etc...
That's my problem :-)

JP
