In shell dialog ,first entry of the dialog not selected directly, I am using shell dialog for open file.

Below is the sample code :

CExtShellDialogFile dlgShellFile(NULL,CExtShellDialogFile::__EFDT_OPEN_SINGLE);

        dlgShellFile.m_comboFileTypes.SetFilter(

          filter

            );

        if( dlgShellFile.DoModal() == IDOK )

        {

            CString pathname;

            pathname = LPCTSTR(dlgShellFile.m_arrRetValNames[0]);

            OpenDocumentFile( pathname );

        }

I check this code for Operating System " Vista "

Also I check the prof UI available  sample examples. (e.g AviFrames) I got the same action, first entry from dialog box is not selecting.

Any thing else please let me know.

Thanks in advance.

Thank you for reporting this issue. To fix it, please update the source code for the following method:

INT CExtShellListCtrl::FindItemByName(
      __EXT_MFC_SAFE_LPCTSTR strName,
      INT nStartIndex, // = -1
      bool bCompareNoCase // = true
      )
{
      ASSERT_VALID( this );
      if( _tcslen( strName ) == 0 )
            return -1;
      if( GetSafeHwnd() == NULL )
            return -1;
INT nItemCount = GetItemCount();
      if( nItemCount <= 0 )
            return -1;

      INT nItemIndex, nRetVal = -1;
      for(  nItemIndex = ( nStartIndex < 0 ) ? 0 : ( nStartIndex + 1 );
                  nItemIndex < nItemCount;
                  nItemIndex ++
            )
      {
            CExtShellItemData * pShellItemData = (CExtShellItemData*)GetItemData( nItemIndex );
            // first, try display name
            CExtSafeString _strNameBuffer = pShellItemData->m_pidlAbsolute.GetDisplayNameOf();
            LPCTSTR _strName = LPCTSTR(_strNameBuffer);
            bool bEqual = false;
            if( bCompareNoCase )
                  bEqual = ( ::_tcsicmp( _strName, LPCTSTR(strName) ) == 0 ) ? true : false;
            else
                  bEqual = ( ::_tcscmp( _strName, LPCTSTR(strName) ) == 0 ) ? true : false;
            if( bEqual )
            {
                  nRetVal = nItemIndex;
                  break;
            }
            // second, try file name
            _strNameBuffer = pShellItemData->m_pidlAbsolute.GetPath();
            _strName = LPCTSTR(_strNameBuffer);
            INT nPosChr = _strNameBuffer.ReverseFind( _T(’\\’) );
            if( nPosChr > 0 )
                  _strName += nPosChr + 1;
            bEqual = false;
            if( bCompareNoCase )
                  bEqual = ( ::_tcsicmp( _strName, LPCTSTR(strName) ) == 0 ) ? true : false;
            else
                  bEqual = ( ::_tcscmp( _strName, LPCTSTR(strName) ) == 0 ) ? true : false;
            if( bEqual )
            {
                  nRetVal = nItemIndex;
                  break;
            }
      }
      return nRetVal;
}

Please note, the automatic shell list view item selection is performed for the file open dialogs only and only of the CExtShellDialogFile::m_bFilesMustExist or CExtShellDialogFile::m_bPathMustExist property is set to true.
