I checked the API reference again, and I found that Quick PDF supports unicode file name, but I need to encode the file name using UTF8. Thus, I use a small function to convert a CString object to UTF8-encoding string. Here are my c++ sample code:

char* CString2UTF8(CString& strSrc)
{
   long  lBufferSize=0;  
   long  lResult =0;  
   long  lSrcLen=0;  
   lSrcLen=  strSrc.GetLength()  ;  
   lBufferSize  =  lSrcLen*  3  +  1  ;  
   //Don't forget to release the buffer
   char  *pCharUtf8  =  new  char[lBufferSize]  ;   
  //Translate  using  code  page  65001(UTF-8).   
  lResult =  WideCharToMultiByte(CP_UTF8,  0,strSrc.AllocSysString(),  lSrcLen,  pCharUtf8, lBufferSize,  NULL,  0)  ;   
   pCharUtf8[lResult ]  =  NULL  ; 
   return pCharUtf8;
}

Sample:

//strFilePath is a CString object
char *pCharPath=CString2UTF8(strFilePath);
 if(m_docQPDF.SaveToFile(pCharPath) == 0)
 {
  delete [] pCharPath;
  pCharPath=NULL;
  return FALSE;
 }
 delete [] pCharPath;
 pCharPath=NULL;

Hi Mingoal!

The path isn't the problem ... the used characters between "mingoal" and "map" are the problem.
You take the path/file-name as a string but in strings you can't work with chinese characters.
The newest versions of QuickPDF are changed to work with unicode-characters, too.
In delphi something like AddImageFromFile(WideString(Edit1.Text),0) <> 0 could work ...

Cheers, Ingo

Hello everybody!

I use QuickPDF to generate pdf, but I find that it does not work as I thought when I pass a string contains characters to functions which need a path as parameter, such as AddImageFromFile(), SavetoFile() etc.

For example:

if(m_docQPDF.AddImageFromFile("C:\Documents and Settings\mingoal\桌面\map.bmp",0) != 0)

{

AfxMessageBox("Quick PDF Load Image Failed! ");

}

Can somebody help me to solve this promble ,or give me some hints ?

Thanks in advance !
