Hi,

When trying to open a pdf file in a directory that has German characters, the returned handle is 0. Which means that the file could not be opened.
The command DAOpenFile when the file is: "c:\\drop\\ùéèçà1232\\pages.pdf". Any solution for that?
I am using "QuickPDFDLL0723.dll".

Thanks,
Ilana.

I can think of 3 ideas.
1. Make sure you send the file name as a UTF8 encoded string to the 7.23 DLL.
2. Try the 7.26 DLL with UTF8 encoding as well
3. Upgrade to version 8 with full unicode support

I am using UTF-8 characters which has their value is bigger then 127. For example one of the characters has the Ansi value  of 199 and 200. Can you please advice? Thanks, Ilana.

Hi Ilana!

Wheeley already told you what to do ...
Try things like this:
QP.LoadFromFile(Pchar( AnsiToUtf8(c:\\drop\\ùéèçà 1232\\pages.pdf) ))
QP.LoadFromFile(UTF8Encode('c:\\drop\\ùéèçà 1232\\pages.pdf')

...and don't forget Wheeley's ideas 2 and 3 ;-)

Cheers and welcome here,
Ingo

Thanks!
For future users, here is the actual code, that works:
In C++:
char *fname = "C:\\Temp\\Digi drop\\ùéèçà123\\pages.pdf";
const int SIZE = 1024; // Bytes
                char* text = new char[SIZE];
                WCHAR w[SIZE]={0};

int erg=MultiByteToWideChar(CP_ACP, 0, fname, -1, w, SIZE); // ANSI to UNICODE
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, SIZE, 0, 0); // UNICODE to UTF-8 
int hndFile = _QuickPDFDAOpenFile (InstanceID, text, NULL);
if (hndFile != 0)
{
int x = 1;
}
In Java 6 - How to get the same UFT-8 path:
public String getAsString (String result)  
        { 
byte[] bt = result.getBytes(); 
ByteArrayOutputStream sw = new ByteArrayOutputStream (bt.length);
                OutputStreamWriter osw;
try {
osw = new OutputStreamWriter (sw, "UTF8");
       BufferedWriter out = new BufferedWriter (osw); 
       out.write(result ); 
       out.close(); 
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} 
        return sw.toString(); 
    }
