i have a program that i want to output data to an editbox
i tried setting the editbox to multiline
i want to post multiple results into the window using 10,13 to make a newline in between each entry
SetDlgItemText works if the string is

TestString db "this is line one",13,10,"this is line two",13,10,"this is line three",0
invoke SetDlgItemText,hWnd,IDC_OFFICE,addr officebuff

the editbox looks like this:

Quotethis is line one
this is line two
this is line three

but not if i do it like this

one db "this is line one",0
two db "this is line two",0
three db"this is line three",0
glue  db  "%s",10,13,"%s",10,13,"%s",10,13,0
.data?
TestString db 512 dup(?)

invoke wsprintf,addr TestString,addr glue,addr DlgName,addr DlgName,addr DlgName
invoke SetDlgItemText,hWnd,IDC_OFFICE,addr TestString

the editbox looks like this:
this is line onethis is line twothis is line three


also how do i append to the editbox to keep adding more data

Quotethis is line one
this is line two
this is line three

this is line four
this is line five
this is line six

Maybe "13,10" and "10,13" have something to do with it? All you need is LF (10) I think.

edit: maybe not

Quote from: SDK
An application may direct a multiline edit control to add or remove a soft line break character (two carriage returns and a line feed) automatically at the end of wrapped-text lines. An application can turn this feature on or off by sending the edit control an EM_FMTLINES message. This message applies only to multiline edit controls and does not affect a line that ends with a hard line break (one carriage return and a line feed entered by the user). Also in multiline edit controls, an application can specify the ES_WANTRETURN style to request that the system insert a carriage return when the user presses the ENTER key in the edit control.

Will,

Depending on which edit control you use and what setting you select for it you have different line terminators for them. A normal edit control usually uses a 13 10 pair. Look up the messages for the specific control you are using, send a mesage putting the caret at the end of the last line, append the line terminator then your next line of text.

I use this to place caret at end of text (for next insertion of text)

and this to add a new line:
