How to add a text on rich edit without erasing existing text?

[ossama]

if you want to insert the text into the end of the text in the rich edit control do this:

Code Select Expand


..
..
chrg CHARRANGE<>
szNewText db "this is the new text to be inserted",0
..
..
;set the cursor in the end of the rich edit text
mov chrg.cpMin,-1
mov chrg.cpMax,0
invoke SendMessage,hRrichEdit,EM_EXSETSEL,0,addr chrg

;insert nex text
invoke SendMessage,hRrichEdit,EM_REPLACESEL,TRUE,addr szNewText


and if you want to replace any selection in the rich edit text do this:

Code Select Expand


invoke SendMessage,hRrichEdit,EM_REPLACESEL,TRUE,addr szNewText


and if you want to cancel any selection and insert the text in the currrent position of the cursor do the following :

Code Select Expand


..
..
mov eax,chrg.cpMax
mov chrg.cpMin,eax
invoke SendMessage,hRrichEdit,EM_EXSETSEL,0,addr chrg
;insert nex text
invoke SendMessage,hRrichEdit,EM_REPLACESEL,TRUE,addr szNewText
..
..

i hope this solve your problem
