In dialogbox, how to use \n or \t char

[wannabegood]

I am a beginner in win32 api programming. Could you please someone help me?

I am trying to use \n or \t, print control char, in a dialog Control edit defined as follows.

EDITDLG DIALOG 0,0,400,300
STYLE DS_MODALFRAME | DS_3DLOOK | DS_CENTER | 0x200L | WS_POPUP | \
WS_VISIBLE | WS_CAPTION | WS_SYSMENU
CAPTION "PS Batch Monitor Dialog"
FONT 8, "Arial"
BEGIN
CONTROL "", IDC_EDITDLG_TEXT, "edit", \
ES_LEFT | ES_MULTILINE | ES_READONLY | ES_WANTRETURN, \
8, 20, 384, 255
....

If I use the 'SetDlgItemText(hwnd, IDC_EDITDLG_TEXT, "hello \n\n THis is testing"'
it prints like this, showing '\n' as unreadable square box?

hello'unreadable square box''unreaderable square box' THis is testing

Do I use other command, not SetDlgItemText or do I have to massage it before using the command? Actually, I am using 'SetDlgItemText(hwnd, IDC_EDITDLG_TEXT, testmsg);' where testmsg comes from Unix using winsock TCP/IP and contains \n or \t character to feed lines.

Thank you very much.

The problem is you are trying to print characters below asc(32).
Try to do a replace(instring,"\n",vbCrLf)
replace(instring,"\t",vbTab )

Otherwise, why not remove them alltogether?

Thank you for the reply. I use Dev-C++, so I do not think it applies to Dev-C++.

The text that includes '\n' to do the line feed comes from the Unix thru TCP/IP, and I am trying to make the message pop up on the window when the message comes from Unix with the text properly line-fed using \n.

I am not good at C++ either, so I am looking for function to replace the '\n' with '\r\n'.

Thank you.
