RE: newline in string resource
StrChr is an instruction which allow you to search a character within a
string.
So, in the example you gave, StrChr ( msg, '\n' ), will return the address
where the
character '\n' can be found in msg.
If you want to add '\n' in msg you should use StrCat.
== StrCat ( msg, \n ); // becareful the second argument is a string

Objet : Re: newline in string resource
I have a string resource that I would like to add some simple formatting
to
with newlines. Is this possible? I'm using \n but am getting errors.
Not sure if this will help you at all, but here's a function I coded
recently (I took out some superfluous stuff, so test it if you use it).
//
// Equivalent of WinDrawChars but handles newlines (lifted from
PalmOS.com)
//
void
cfDrawChars(Char* msg, short xp, short yp)
{
Char* c;
UInt16 msgLen;
while (msg)
{
c = StrChr(msg, '\n');
if (c == NULL)
msgLen = StrLen(msg);
else
{
msgLen = c-msg;
c++;
}
WinPaintChars(msg, msgLen, xp, yp);
yp += FntLineHeight();
msg = c;
}
}

Re: newline in string resource

Agus,
As Joe pointed out in this thread, WinDrawChars will not process a newline
character ('\n') as one might expect and will instead keep all of the text
on a single line, rendering a box character where the newline characters
appear in the string. The function I posted is an alternative to
WinDrawChars that will process a newline character.That is why StrChr
(and not StrCat) is used -- to find the location of the newline characters
in the string.
You should make the attempt to understand what the code does before posting
corrections.

If you are using Constructor, just hit the Enter/Return key where you want to insert the newline in your string. How are you trying to display the string on your handheld? This won't work: Char str[] = abc\ndef; WinDrawChars( str, StrLen(str), 10, 100 ); because WinDrawChars doesn't know what to do with unprintable chars. This will work: Char str[] = abc\ndef; SetFieldTextFromStr( MainForm, MainFField, str, true ); if MainFField is a multi-line field (and if you write the SetFieldTextFromStr function), because fields know what to do with '\n'. __ Do You Yahoo!?
