• Boogeyman777 SslStream.Read() - Returns invalid data

  Hey, I am currently attempting to implement a multi-threaded C# socket, using SSL (.pem file/certification/private key combo) server using Visual Studio C# Express. I have successfully made the client application establish a connection, and send data, which appears in plain, de-crypted text on the server - this works. However, I am 'polling' the socket to see if data is available to read. Here is some code which is appropriate: ---- public void Process(int threadId) { int BytesRead = 0; try { Master.Log("BEGIN READ"); sslStream.ReadTimeout = 5000; BytesRead = sslStream.Read(bytes, 0, bytes.Length); Master.Log("READ " + BytesRead + " bytes"); if ( BytesRea ...Show All

• dzimmy BitVector32 purpose?

  Experts, I'm trying to take in Collections and have run across the BitVector32. Is the sole purpose of a BitVector32 item optimizing available hard drive space (Example: Using 3 sections of a BitVector32 to store 10, 1, and 192 instead of 3 external 16-bit variables) I only ask because it seems the practice of utilizing bit packing for number storage outweighs any small advantage gained in space conservation or is there an aspect / capability to BitVector32 I'm missing Thanks in advance ~ Chris McQuade It is to conserve memory, not disk space. Fairly common in the olden days but increasingly irrelevant with 1 GB of RAM. You'll trade speed for space. The equivalent C/C++ concept is bit-fields . Note that BitVector32 is a ...Show All

  Hi, I need some help with the Web Service security. I have a web service that picks up a file from a folder (any folder, network, local etc) and sends it using SMTP to a mail recipient.

• Haojun Parsing double value from a string

  Hi all, I need to parse a string which is in the following format (example): -0.0004 USD/Tonnes Basically, it will be a double value, might be preceded by the negative (-) sign and followed by <Currency>/<Unit of Measure> . The result should be just the double value (with the sign if its there), as in the above example, it should translate to -0.0004 I wanted to know if there is an easy way of doing it in C#, like using the Double.Parse() or the string.Format() methods (I tried them both but couldn't get them to work) Or do I have to parse the string character-by-character to get the required result Thanks in advance, MadMonk P.S.: Apologies if its a silly question, I'm still a newbie in .NET ...Show All

• Kushu RFID Reader Project

  Hello, I'm currently working on a project which involves a serial port RFID Reader. I have connected the Reader to COM2 of my PC and i'm trying to get the signals from the RFID Tags.

I also wanted to ask you if you have any code samples to send me or if any of you has written a similar program that works. I need to fix t ...Show All
