Is there any complete reference/documentation (website, Document or CHM-file) to the PDFView ActiveX control?
I have downloaded the free trial version of the control, to demo the features of the control to our customer, and would like to use the OpenPDFFromMem - method, but as I see is there only some examples to illustrate some of the features of the control.
Best regards
Customer
--------------------------------------------------
Thanks for your message, OpenPDFFromMem() function does open and view the PDF file from memory,
BOOL OpenPDFFromMem(long lpPDFData, long nPDFDataLen, LPCTSTR lpszUserPwd, LPCTSTR lpszOwnerPwd);
Please refer to following C++ example for this function,
void CSampleDlgDlg::OnBnClickedButtonOpen()
{
char szFilter[] ="PDF File (*.pdf)|*.pdf||";
CFileDialog fSaveDlg(TRUE,"","",
OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
szFilter,this);
if(fSaveDlg.DoModal() != IDOK)
return;
CString strFileName = fSaveDlg.GetPathName();
#if 0
m_PDFViewer.OpenPDF(strFileName, "", "");
#else
//----------------------------------------------------------------
//
// Memory Open
//
//----------------------------------------------------------------
CString tmp = _T( "" );
HANDLE hFile = ::CreateFile( strFileName, GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL );
if ( hFile == INVALID_HANDLE_VALUE )
{
tmp.Format( _T( "CreateFile ERROR [CODE = %d]" ), GetLastError() );
AfxMessageBox( tmp );
return;
}
DWORD dwRead;
DWORD dwSize = ::GetFileSize( hFile, NULL );
BYTE* pBuffer = new BYTE[ dwSize ];
memset(pBuffer, 0, dwSize);
if ( !::ReadFile( hFile, (LPVOID)pBuffer, dwSize, &dwRead, NULL ) )
{
tmp.Format( _T( "ReadFile ERROR [CODE = %d]" ), GetLastError() );
AfxMessageBox( tmp );
::CloseHandle( hFile );
return;
}
::CloseHandle( hFile );
BOOL bRes = m_PDFViewer.OpenPDFFromMem((long)pBuffer, dwSize, "", "" );
if ( !bRes )
{
AfxMessageBox( _T( "Open error!" ) );
}
#endif
CString csCurrentPage = _T( "" );
csCurrentPage.Format( _T( "Current Page : %d" ), m_PDFViewer.GetCurrentPage() );
AfxMessageBox( csCurrentPage );
m_PDFViewer.SetMsgCallbackWnd((long)m_hWnd);
}
