Hi,

I have a line, in a text file, that represent a folder name. It is, however,
in unicode and is given as hex digits. How can I read the folder name and
use it in functions like "OpenFile" or the OpenDialog box. The line looks
like:

hex(2):25,55,73,65,72,50,72,6f,66,69,6c,65,25,5c,4c,6f,63,61,6c,\
  20,53,65,74,74,69,6e ...

Thanks,

Is the file storing the actual binary values of each character, or just
string representations of the numericdigits?  That makes a big difference.
Can you post the actual file to the .attachments group for us to look at?

Below is excerpt of the file. The whole file can be recreated from the
command line by asking "regedit.exe" to export a key-hive as follows:
regedit /e:a ident.txt "HKEY_CURRENT_USER\identities"

This exports outlook express data into a text file. What I'm interested in
is the value of "store root" which represents the folder outlook express
stores data.

Thanks,

What OS are you running under?  I assume WinNT/2K/XP?  On my Win98 machine,
the "Store Root" value is a simple ASCII string:

    "Store Root"="F:\\Program Files\\Internet Mail and News\\Gambit"

For what you're asking, you'll have to manually parse the string into its
individual digits, and then you can use StrToInt() to convert the strnigs in
actual numeric values and then cast them to wchar_t as needed.  For example
(untested; error handling ommited for simplicity):

    AnsiString asStoreRoot = extract "Store Root" value from file;
    WideString wStoreRoot;

    if( asStoreRoot.SubString(1, 3) != "hex" )
        wStoreRoot = asStoreRoot;
    else
    {
        // remove "hex" prefix...
        int pos = asStoreRoot.Pos(":");
        if( pos != 0 ) asStoreRoot.Delete(1, pos);

        // strip off "\", spaces, and line breaks...
        TReplaceFlags flags = TReplaceFlags() << rfReplaceAll
        asStoreRoot = StringReplace(asStoreRoot, "\\", "", flags);
        asStoreRoot = StringReplace(asStoreRoot, "\r\n", "", flags);
        asStoreRoot = StringReplace(asStoreRoot, " ", "", flags);

        // tokenize the digits...
        TStringList *digits = new TStringList;
        digits->CommaText = asStoreRoot.Trim();
        wStoreRoot.SetLength(digits->Count);

        // convert the digits...
        for(int x = 0; x < digits->Count; x++)
            wStoreRoot[x] = (wchar_t) StrToInt("0x" + digits->Strings[x]);

        // cleanup
        delete digits;
    }

    // use wStoreRoot as needed...

Thank you very much. The solution is very helpful. Thanks again.
