You need to set the ES_MULTILINE style. It's one of the check boxes in the designer, or use the style in your CreateWindow call.

(If that still fails, try \r\n, but it should work).

Hi,
Yeah if I define as multiline it is working.
But it is working only if I give manually like
SetWindowText("red\r\nblue\r\ngreen");

But if i get the data from external source via UART I am collecting in a buffer.
Buffer contains the chars 10,13 after each word.
Then I directly do SetWindowText(buffer);In that case it is displaying in a single line,
not in multilines.

So what should be done if I have to display the data in multilines whenever i come across 10,13 characters.

Please help!

Sunil Kumar

Replace 10 with \r and 13 with \n ?

Hi Rajesh,
Is there any difference between 10 and '\r' , 13 and '\n'.
I think they are ascii euqivalents only na??

In the buffer if I replace 10 with '\r', in the debug mode I am able to see 10 only as it is the ascii
euivalent.

So, that was the reason why I asked you for the code. Also, I'd like to see how this 10 and 13 are coming within a string. It is impossible to tell you anything without looking at your code.

Yes.

You're wrong:
10 is the ASCII code for '\n'
13 is the ASCII code for '\r'.
(i.e. you're getting the characters in the reverse order).

My first thought was "Hmph, of course it works..."

But I thought I'd get some evidence before acting all superior.

This does not work:

CString buf;
buf += "Hello";
buf += char (10);
buf += "There";
SetDlgItemText (IDC_EDIT7, buf);

This does not work:

CString buf;
buf += "Hello";
buf += char (13);
buf += "There";
SetDlgItemText (IDC_EDIT7, buf);

This does not work:

CString buf;
buf += "Hello";
buf += char (10);
buf += char (13);
buf += "There";
SetDlgItemText (IDC_EDIT7, buf);

This works!

CString buf;
buf += "Hello";
buf += char (13);
buf += char (10);
buf += "There";
SetDlgItemText (IDC_EDIT7, buf);

Which comes as a bit of a surprise to me... Needing both CR and LF is no shock, but which order? Quite a surprise.

How you solve it is up to you really. Your reading from the UART routine could simply swap char(10) with char(13) and vice versa.

Or your routine that puts the text into the screen could.

You could put it in a string, and do a replace like so:

while (1)
{
   int nFind = MyString.Find ("\n\r");
   if (nFind < 0) break;
   MyString [nFind] = '\r';
   MyString [nFind+1] = '\n';
}

The choices are (near) endless.

Iain.

Yeah Iain,
It is a bit surprise.
If I change the order , like if 10 is replaced with '\r' and 13 is replaced
with '\n', it is displaying in multilines.

you mean, pure file copy ?

or you want to copy internal parts of it only ?
if so, you must know the format of the file first...

No i have already done file copying.

In file copying the exist data is removed.

So i want write data from source file to dest file,without losting of existing data of dest file.

So please tell me how can i do this ?

Hence you don't need a copy: you need to add the whole content of a database to another, not-empty, one. I think you should do it without bypassing the database engine (i.e. you have to use SQL or an Access tool).

I think the best approach is
Search for an Access import/export tool and then use it.
If you cannot exploit the above then use SQL, but it won't be a painless task, I presume.

wait, isn't that a copy for you (a copy of data) ???

you take the entiere source file content, and you write it entierely into the destination file as is. right ?

ah, you want to append the source file to the dest one.

hum, I could always propose the bare solution, which will copy the data like needed, but i'm not sure the destination mdb will be still valid afterward.

is it a binary file of a text file ?
and do you know the structure of the file (how the data are set inside the file) ??

oh and by the way, where are those .mdb file coming from ?
