Summary:
SYMPTOMS
When an application runs under Windows 3.0, text in a message box
or in a child-window control appears on two lines, as desired.
However, under Windows 3.1, the same text appears as one line with
two vertical bars at the position where the line break should
appear.
CAUSE
The character sequence "\n\r" was used to separate the two lines of
text.
RESOLUTION
Modify the text to use the character sequence "\r\n" to break lines
of text.
More Information:
In an application developed for the Windows environment, various text
strings can contain an embedded carriage return-linefeed pair to
display the text on two separate lines. For example, an application
can send the following message to a multiline edit control in a dialog
box to display the string "This is a test" on two lines with a break
between the words "a" and "test":
SetDlgItemText(hDlg, IDC_MEDIT, (LPSTR)"This is a\r\ntest."));
Under Windows 3.0, both the "\r\n" and "\n\r" strings create a new
line in the output text. However, under Windows 3.1, only the "\r\n"
string creates a new line in the output. The "\n\r" string creates the
two vertical bars discussed above.
