Hello!

I have build a small application for my WinCE device. The App is
working fine, but now I want to read / write to a textfile on the SD
card inside my system.

I tried to use AssignFile, Reset,Write,Writeln,... but it doesn't
work. The app hangs after such operation.

Has anyone an idea and can help me with that?

Thanks in advance

Almost impossible to say without information. ;-)

Have you tried using a StringList instead?
like:

Code: [Select]var sl:TStringList;
begin
sl:=TStringList.Create;
sl.LoadFromFile('AFileName');
sl.SaveToFile('AnotherFileName');
sl.free;
end;

Or Memo1.Lines.LoadFromFile(..);

Hello!

Yes, I have tried both examples, and both didn't work.

What infos do you need which could help solving this problem?

I really have no idea why this doesn't work and haven't found a tip in
the internet.

Can you help?

Best regards

I don't think so. I'm not an expert for WinCE

Try to add the full path to your filename because Wince have no
currect directory.

Now a really stupid question!!!

How does a full path look like? Is there a C: or D: in WinCE?

Does a path look like this:
/data/mytext.txt
or
c:\data\mytext.txt

Thanks for your help

Without C: or D: just \
\data\mytext.txt

but you can make relative path from you exe file

s := Application.Location + 'mytext.txt';
or
s := Application.Location + '..\data\mytext.txt';
