I have problems getting Acrobat PDF programmatically getting the filename to print the PDF using the register.

I need help with getting Acrobat to bypass the save dialog for filenames in order to programmatically add the filename and continue printing using the Windows registry.  I have been reading in distiller manual and Q&A sites that this would work.    I did get filenames listed in the registry sometimes, but nothing happened.  Most of the time I
get  my document path only and untitled.pdf as the filename.  Once I got the filename only with no path.  Here is some code attached below...

Open in new window

void CMainFV::SetAdobeRegistryPrint()
      CHPCCiDBApp *pTheApp = (CHPCCiDBApp *)AfxGetApp();

        LPCTSTR lpValueName;
      CONST BYTE *lpData;
      DWORD cbData;

//      HKEY hkey; // defined in mainfv.h

      if (RegOpenKey(HKEY_CURRENT_USER,_T("Software\\Adobe\\Acrobat Distiller\\PrinterJobControl"),&hkey) != ERROR_SUCCESS)    // (handle to open key,,  subkeys to open, handle address to open key
                  AfxMessageBox("Unable to open registry key!", MB_OK);

      if (pTheApp->OS_ProcessorType == 64)
         lpValueName = "LastPdfPortFolder - splwow64.exe";
        // lpValueName = "40cd65f0";

      else  // 32

            AfxMessageBox("just a check!", MB_OK);


      if (RegSetValueEx(hkey, lpValueName, 0, REG_SZ,  (LPBYTE) "C:\\Users\\JOHNM\\Documents\\FUNZ.pdf",  strlen("C:\\Users\\JOHNM\\Documents\\FUNZ.pdf") * sizeof(char)) != ERROR_SUCCESS)
            AfxMessageBox("Unable to set registry value name!", MB_OK);
            AfxMessageBox("Registry value name set!", MB_OK);

why not calling ShellExecute with "print" option?

if acrobat was associated to .pdf print, you would call

ShellExecute(NULL, _T("print"),  strPathToFile, NULL, NULL, SW_HIDE);

Open in new window

where strPathToFile should be a full qualified path to the pdf file to print.

if another printer for .pdf is associated (type "assoc .pdf" in a command window) you could try

ShellExecute(NULL, _T("print"),  strPathToAcrobatExe, strPathToFile, NULL, SW_HIDE);

Open in new window

which would invoke acrobat and pass the filename as first argument.
