Copy Memorystream to widestring

Hi all,

how can I copy the contents of a memorystream into a widestring?
I can do it for a string, but widestring doesnt work.

procedure TForm1.Button1Click(Sender: TObject);
var
SourceString: widestring;
MemoryStream: TMemoryStream;
begin
....
MemoryStream.Position := 0;
SetLength(SourceString, MemoryStream.Size);
MemoryStream. ReadBuffer(Pointer(SourceString)^,Memory
Stream.Size);
Caption := SourceString;
...

Can someone help me out? I m stuck.

Thank you.

try
 ReadBuffer(Pointer(@SourceString[1])^,Me
moryStream.Size);

P.S.
when Setting the Length on Widestrings, the memory hole
normally ends up as twice the size in the widestring.
for example
10 characters = 20 bytes + 2 Bytes for termination.

Same result. What I basically get is a whole bunch of '?'s as part of
the widestring.

yes, you most likely are!.
Widestring are 2 characters each.
you need to use something that shows
unicode.
also, if you are seeing this at the end of the string it is
because of what i told you before.
widestring is 2 chars each character.
setting the length of the string longer than what memory your
going to transfer into it is going to leave some uninitialized
memory at the 50% mark to the end.
if your trying to fill a WideString with normal chars, i would
suggest to transfer it to a simple string first then simply
assign the WideString from the normal string..
this will help you in converting between the two, the compiler will
fill in the blanks for you. (sort of)..

I think the problem is that the stream (the webpage) contains a
mixture of unicode and normal characters. Is there a way to work
around this?
