Hi,

I'm trying to save the layout of the commands bars into a string using PropExchange tool, but, everytime I put a character that is not UTF-8 in the caption of the button, I'm not able to read the string again.

The code is something like this...

CXTPCommandBars *pManager;

<...>

CXTPPropExchangeXMLNode px(FALSE, 0, _T("Settings"));
px.SetEncoding( _T("UTF-16") );

XTP_COMMANDBARS_PROPEXCHANGE_PARAM param;

<...>

pManager->DoPropExchange(&px, &param);

CString data = px.GetXML(true) );

// data string seems to be ok.

// to read the file

CXTPPropExchangeXMLNode px(true, 0, _T("Settings"));
px.SetEncoding( _T("UTF-16") );

XTP_COMMANDBARS_PROPEXCHANGE_PARAM param;
<...>

if (!px.LoadFromString( data )
{

fails!!!! because of the non utf8 character in the caption

}

I need to use UTF-16, but I'm not sure what I'm doing wrong.

Please note that I have a similar code for the DockingManager and it is working fine with non utf8 caractares.

Regards

Correction!

It does not work for DockingManager also.

A string like this one "competi��o"( Portuguese word, same as "competition" ) invalidates all the xml.

Hi,

Do you compile with Unicode ?

No, i'm not using Unicode, but may be I do not need to use utf-16, i really don't know.

px.LoadFromString( data ) fails with this string, if i use �� instead of ca.

Hi,

Whithout Unicode you can't use Utf-16. Utf-8 will work for you, but in this case you have to write/read directly to file.

instead GetXML use SaveToFile.

also try insead

px.LoadFromString( data )

write

px.LoadFromString( _bstr_t(data ))

Hi,

I cannot read/write to a file, I'm using a huge configuration file to write all my presentation stuff, not only codejock stuff, but also adhoc and other libs, it would be very complicated if I had a file for each one of the commandbars and dockingmanagers from xtp.

Is there any other way I can make LoadFromString to work ?

Did you try px.LoadFromString( _bstr_t(data )) ?
