.net - DotNetZip extracting to stream problems using provided code sample -


I am trying to open a zip file and extract a password and 256 AES encrypted text file in a stream without which I Put a copy of the text on the drive you can read if I understand what I want to do correctly, then using a stream I have to complete it. I am not experianced with a lot of code, so im using the example I found on DontNetZip site which is bellow. Problems 2 times, it throws 2 errors when processing, I expected that someone can help with these

1 occure the first error on the 3 line - "As the CrcCalculatorStream = e1.OpenReader uses the" error 'object reference is not set for an instance of an object,' I have tried declearing and new and still it crashes on that line 2 second error is after a line on a loop - "If (s.Crc32 > e1.Crc32) then there is a squigly line under" error and S.Crc32 and it is sais that CRC32 Under CrcCalculatorStream, e1.Crc32 is not a member of a similar error which is not a member of Ionic.zip.zipEntry

is the code that has been copied from this link

PS I made reference to a file in your real program and edit the ZIP name, the only additional password.

Thankyou 

  New zipfile (ZipFileToRead) as ZipEntry = zip.Item ("Elevation.mp3") as Dim E1 using the form of buffer byte as zip Use Dim Dim as the Ionic.Zlib.CrcCalculatorStream = e1.OpenReader (password) in the form of diminished integer () = new byte (4096) {} dim total Read bytes as integer = 0 N = s .Read (buffer, 0, buffer length); Totalbiered = (Total Bytes Reed + N) while loop (n> gt; 0), then (s.Crc32

end use

I managed to organize it out, just think I could be useful to anyone. Use the StreamReader = New StreamReader as the Ionic .Crc.CrcCalculatorStream = e.OpenReader (password) as the

string as a string 

  Str = sr.ReadToEnd () ending using sr sr

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
