c++ CDC to pdf

[makina]

I've got a CDC and I need to export to pdf
Do you have a sample which makes this ?
Thank you for your help

Voilà ce que j'ai fait
voyez-vous une erreur ?

{

//Check if retrieved printer handle
if ( NULL == m_hPrinter )

GetLastErrorMsg( buf, sizeof( buf ) );

}

CDISetDefaultPrinter( m_hPrinter );
SetDefaultFileName ( m_hPrinter, _T(m_strFileTo) );

//Need to do this each time output is sent to the PDF Converter
EnablePrinter ( m_hPrinter, m_szCompany , m_szCode );

PrintBmp();

Do you think I need to make a bmp with my CDC first then convert to pdf ?
Can't I convert my CDC to pdf directly ?
Thank you for your help

Hello,

I suggest that you call enablePrinter() when catching the EnablePre() event.

Hope this helps.

[makina]

No, unhappily it does not help
but would you have a example which would take a CDC and write to pdf ?
or do you see where I could have done a mistake in the examle I gave before ?
thanks
