XlTable format with Unicode

[Chris Trengove]

Does the XlTable format (for DDE with Excel) allow passing Unicode
strings, and if so, how is it done?

Thanks

Hello Chris,

I understand that you want to know whether the XLTable support Unicode.

Currently, I am performing research on this. I appreciate your patience.

Wei Lu,

The XlTable format can be received by Excel when performing DDE
operations; in fact it is often recommended for use because it is
supposed to be fast. The format consists of a concatenated sequence of
records. Each type of record begins with a single byte to indicate the
type of record. Strings appear with 0x02 (floating point numbers are
0x01, etc). Strings are then encoded with a length word, followed by
the string bytes themselves.

So, my question is, if the strings are Unicode (requiring two bytes per
character), what happens then? Is there is a separate record type? Or
is there some trick to enable Excel to receive the Unicode string using
the
regular (0x02) string record? Or is it just not possible?

Thanks
Chris

Hello Chris,

Well, DDE is existing since Windows 3.0, it is too old that I could find
little documents on it.

Finally, I found a internal KB explain the XlTable Format.

Here is an example:the Fast DDE Table for a selection consisting of three
cells in a row, containing the strings "East", "West", and "North",
respectively, will resemble the following:


10 00 04 00 01 00 03 00 - tdtTable, 4, 1, 3
02 00 10 00 - tdtString, 16
04 45 61 73 74 - 4, East
04 57 65 73 74 - 4, West
05 4e 6f 72 74 68 - 5, North


I don't think it support Unicode because when DDE existed, there is no
unicode yet. So the designer of DDE did not consider it.
