I have to make files encrypt in my application. Now, I'm writing the encrypted data to temporary files (fsOutput in the code). I upload this file by FTP to the server. How should I rewrite my code if I want to upload without creating a temporary file and by using stream? My FTP client is able to upload from stream. My FTP client uses PutFile method to upload files ('Upload from stream by StarkSoft ftp.net in my code)

I'm attempting to use symmetric encryption to encrypt some data, and store the key necessary to decrypt with the data in a MemoryStream. (While I know that this alone is really dumb security-wise, I'm going to use RSA to encrypt the symmetric key. Right now, though, I'm trying to just get this part to work.)I'm using the FileHelpers library to parse the data for my delimiter (the semicolon, as I don't believe I'll ever have a semicolon in the data). Unfortunately, in my decryption function, when it's parsing, it only returns back one record. And, if I show the entire string of encrypted data created at the end of this function, it doesn't appear to be using multiple records.I'm wondering if when I create the new cryptostream, it's defaulting to the beginning of the memory stream, so when I write my encrypted data, it overwrites the data I had just written to the memory stream.[code]

View 3 RepliesI've found a script on a microsoft site which should clear the temporary internet files folder:
Const TEMPORARY_INTERNET_FILES = &H20&Set objShell = CreateObject("Shell.Application")Set objFolder = objShell.Namespace(TEMPORARY_INTERNET_FILES)Set objFolderItem = objFolder.SelfstrPath = objFolderItem.Path & "*.*"Set objFSO = CreateObject("Scripting.FileSystemObject")objFSO.DeleteFile(strPath)
For some reason this script doesn't work for me. It get's the proper folder becauseI used Wscript.Echo objFolderItem.Path to print the path but the files are not deleted.

View 14 RepliesI have created an updater for our clients application. The way the updater works is to download all the updated files and store them in a temporary folder then check the file hashes. If everything is ok it will copy the files to the applications installation folder. Once this is been completed it will delete all the updated files in the temporary directory.
My problem: I am looking for a directory that will be available for XP, Vista, and Win7. I was thinking about the 'temp' directory.

View 5 RepliesI am attempting to find some code to use in VB.NET to decrypt a string that has been encrypted using the Java crypto libary.All of the code I have found so far uses an Initialisation Vector and Key to decrypt but the string has been encrypted using the Key only. (Using an Initialisation Vector is apperently an optional step in Java).Does anyone know of code that I can use (preferably in VB.NET but i could convert C#) to decrypt AES 128 Bit encoded string without an Initialisation Vector?

Public Function GenerateHash(ByVal SourceText As String) As String
[code...]
The DB has a field "end date" and 1753/1/1 is supposed to be the value representing nothing, as we cannot assign null to datatime in sql server..
In reporting application the select querry used, gets the data including those 1753 date values. good
Problem 1753 date causes hell with report calculations. there are a lot of calculations in the report and changing the code to ignore 1753 will be a headache, so i was thinking Is there a way to tell sql server,
SELECT *
FROM TABLE BUT IN END_DATE
WHERE VALUE='1753/1/1 01:00:00.000' REPLACE WITH PARAMETER1
CRUDE EDIT (donot have access to debugger currently)
i cannot remember but i get an error like "nothing should be mapped on something" when i insert record with null date! THIS HAPPENS ONLY WHEN USING VB.NET in csharp it works fine. do you know why??
I have a VB.Net application that populates an Oracle 11g global temporary table. I can see data in the temporary table by loading it into a grid and everything looks correct.However, when I call an Oracle stored procedure from VB.Net that would manipulate the data in this temporary table, the stored procedure reports that my temporary table is empty.I understood that data in an Oracle global temporary table should be visible to all sessions.
View 1 RepliesI want to get input data from user and encrypt them and save to database. Is it possible to retrieve this encrypted data and show in DataGrid?
View 3 RepliesAs we pass data to a database in a clear cut way, there may be situations, when we might fear data stealing. So can we simply encrypt data at the time of insertion, so that the data privacy will be maintained and the front end can only see the data.
View 1 RepliesI have been using RSACryptoServiceProvider and was using the template code provided from the MSDN resource page.url...I wanted to encrypt the data on my computer and transfer the data to the FTP server and have it decrypted there. I have the encryption and decryption code but it is in the same program and only work during the instance it is open. The intention is to have a program that will encrypt and send the data to the FTP Server. There will also be a VB Script on the server to decrypt the data and store it in a separate location. How do I get it to store the public key on my computer and the private key on the server? Also, how to I transfer the encrypted data over to the FTP and have it saved there?The purpose of this project is that we have people located over the globe and are sending sensitive information to an FTP server at the home office. My boss has insisted on the data being encrypted before sending anything. But, on the server it will be decrypted so that a select few can go through the information.
