FTP The Server Committed A Protocol Violation?
Dec 19, 2010
Currently have a program on the market and just did a major update which 100s of people downloaded, the problem is that that update had a major bug which made it crash. So quickly got to work to fix the bug but everytime I connect my software to the FTP database I get this Error Message:
"The underlying connection was closed: The server committed a protocol violation."
I triple checked my code. Everything is right One minute it was working the next minute it wasn't,My buyers are getting very frustrated and I've had to cancel all orders due to this., The bug in the update software which I have now fixed but this other bug to do with protocol violation.I havent tested if its just now my computer that the error messages comes up or it happens on others.I've tried 3 seperate FTP servers and all the same results?

I am trying to make an application which logs on to a server using the telnet protocol runs a couple of commands and stores the output of these commands in a text file.The problem is that I cant really seem to figure out how to negotiate the telnet commands. I have done a packet capture of a telnet session todifferent servers using a packet capturing program and I dont seem to find any fixed pattern. Every server negotiates the command in its own different way and in a different sequence, moreover the commands exchanged are not the same.
What I want to do is to exchange the bare minimum commands which will allow me to log on to any server via telnet, run my commands, take the output and logout.I have searched the internet for such a set of 'general' telnet commands but I wasnt able to find any.

I have a very simple database application where I have an underlying table connected to a form with a text box for each underlying field. I have added a databinding navigator, and then created a dataset and bound each text box to the dataset (all using the IDE tools in VS 2008 Pro). When I run the program, I can load all of the entries from the database, create new ones, and scroll through all of the entries (including the new ones), and make changes. The changes are kept withing the program, so if I make a change to an entry, then move to the next one, and move back, the changes remain, but when I look at the underlying database, none of the changes are in the database. What am I doing wrong? Is there some sort of command that I need to run to commit the changes to the database?

I am trying to change some properties with a property page during design time. The properties get set okay and the form updates (graphically) and the new properties appear in the property list, however they do not get written to the designer. If I close the form I am on and then reopen it the changes have been purged. However, if after I make a change with my property page, I manually change anything on the form, then it knows it is dirty and commits the changes to the designer.

I am new to VB Studio.Net 2010 and trying to learn how to use it by tackling a small project.I started a brand new project and created a blank form with the following code. It is linked to an encrypted SQL Server Compact database that has two tables, tblComports and tblParams, and I have allowed the password to be saved with the connection string. The code seems to run without a fault and the message box pops up showing "256", which implies to me that the records were added to the table and should have been committed to the database since I re-issued a Getdata() after I issued the Update. Yet when I select "show table data" for tblComPorts from the Database explorer for tblComPorts it is still only an empty table.
To further confuse me I added a DataGridView control to my form and linked it to tblComPorts. When I ran the code first time it confirmed my failure by showing me an empty table. I ran it a second time and the table was filled. Now every time I run it the

I'm developing a filetransfer app in VB.Net..The sizes of the files vary, but can get up to 10+ GB.I already create a chat app as a test.On the clientside I run this code to connect to the server.[code]Can I also use this to transfer files?I want the app to work through a firewall and stuff.So I think I need the outgoing data on the client to go through port 80. On the server I want to be able to receive the data on another port (E.g. 8888). Is this possible?And final question is. What protocol should I use for this purpose TCP or UDP.

Can i implement PTP (precision time protocol) or NTP (simple network timing) with sockets?
If so, how can i use them to send small packages (4 to 33 bytes) with the smallest delay possible?
P.S. I would prefer to know more about PTP, I've heard that it has smaller delay.

What I'm trying to do is get the information stored in a little "electronic card" trough a reader connected to my comport. I found a ActiveX protocol to communicate with the reader, but I've no idea how to use it. I'm pretty new to VB.net, and I don't have much experience in coding.So what I'm asking for is how do I use a protocol like this in a VB.net project?
Dim reading As New EmitEpt.EptReading
But that gives me the error "'EmitEpt.EptReadingClass.Friend Sub New()' is not accessible in this context because it is 'Friend'."If I remove "New", then I get the following error: "object reference not set to an instance of an object".

I'm using an Asynchronous Method to send data across the TCP Protocol. For the most part it seems to be working, but recently, I've been getting results that have missing bytes to them. How am I actually able to figure out what's missing on the sender's site and make sure all the data gets to the end? For example: my end client receives 1408 bytes of data when I sent 1532 bytes. I sent an array with a length of 1532 and the client only got 1408.
