VS 2008 Received Bytes Threshold?

Feb 4, 2012

I just wanted to confirm my reading -- this is the number of bytes that is put in the buffer before the data received event is triggered, correct? And it's ONLY for that purpose?

[2008] Serial Port Received Bytes Is Zero?

Mar 12, 2009

In my serial port application, I have my code -

Private Sub SerialPort_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort.DataReceived
Dim cnt2 As Byte

[code]....

For some packets I sent, "Error Data Received" came up. I checked BytesReceived, it was 0. My question is: since SerialPort_DataReceived processes data received, data was supposed to be received. Why the number of bytes I read was zero? BTW, when is this event accessed? it is accessed when any number of bytes received or the whole packet received?

VS 2008 What Does This Line Exactly Do - I = Stream.Read(bytes, 0, Bytes.Length)

Dec 28, 2010

What exactly does this line do?

i = stream.Read(bytes, 0, bytes.Length)

Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.

i = stream.Read(bytes, 0, bytes.Length)
While (i <> 0)
Try
' Translate data bytes to a ASCII string.

Find Outermost Threshold Values Of Array In Program?

Jun 22, 2012

Basically, I have an array of data with about 1000-2000 data points that form a rough Poisson distribution. What I need to do is take the maximum value of the distribution (which I know), and find the leftmost and rightmost values that are, say, 70% of the maximum. (I don't really care what the value of these numbers are. I want to know what index position they are in.) I then want to find the centerpoint between these two indices, rounding if necessary, and return all three values (left, right, and center).

I want to create a page name "parameter link" where the user can edit and change the value of the threshold. For now, what I have is, all user can change the threshold permanently. What I want now is the user can only change the threshold value during the session only, and the value will reset back to the previous value when the other user login. Only admin will have the privilege to change the value of the threshold permanently., but I don't know where to start.

VS 2008 How Many Proper Payloads Server Received

Aug 24, 2009

I took a look at System.Security.Cryptography.MD5 class about using a checksum for a UDP program i am making.Basically i want to use it, to ensure the server is receiving what the client sends it, in a way that the server can make note of it receiving properly without having the client keep track of how many proper payloads the server received. The reason i need a checksum is because the client is sending a random hex payload, so i cant have the server predict what it should receive the same way as i have it working with the sequence number.I dont fully understand how i could implement this to my code. I believe i should make a public property in my packet class, but im having trouble implementing it with the way i coded my program. [code]

VS 2008 - Password - Received An Error About Frontpage Extensions Not Being Installed

Jul 10, 2009

I've been trying to publish some software for 2 days. At first, I received an error about frontpage extensions not being installed so I installed them, only to screwup the ht.access file on my site and lose my web site for 5 hours.

I had an email this morning from Lunarpages saying they installed the extensions, recoded the ht.access and even tested frontpage on it. SO -- I tried again this morning and still received "the components for the frontpage extensions are not installed". ?

AND --I must be missing something and looked everywhere in VB.NET (options etc) but how in the heck can you publish something directly to your website (I used the wizard and setup all the publish options) and NOT be prompted for your user ID and password? Obviously, VB.NET has it's own ftp program.

It reads the 5 bytes I added to the encrypted file, but I want the CryptoStream to start from the sixth value and then copy the original bytes into the decrypted file, but it gives me an error:

Padding is invalid and cannot be removed.That's why I'm trying to make it read from the sixth value and then continue copying normally, but I'm stuck.
