Correctly Encoding ByteArray And Sending To Host Program
Jul 17, 2009
I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.

I want to send a image to server side using HTTPService,I am using ASP.NET for server side coding. I don't know how to write server side code to receive the image sent as a byteArray, and I am also not sure if my client side code is correct or not。is there any IT PRO..[code]I could not get the image in my disk,I think the flex side should have not problem, but the VB code side should be something wrong.

The main problem is that to send an E-mail from G-mail, you need to use smtp.gmail.com as the host, and the port number 587.
Dim SMTPServer As New SmtpClient
SMTPServer.Host = "smtp.gmail.com"
SMTPServer.Port = 587
SMTPServer.EnableSsl = True
However, for Hotmail, I would need a different Host and Port, smtp.live.com. Other E-mail clients would therefore require more different hosts. Is there a way, to address all of them without listing all possible E-mail host names and ports?
If not, what alternative is there to supporting all the E-mail hosts without throwing an error?

I am working on an addin/plugin for CAD software called Solidworks. I use it to batch process files (print, save, etc). One thing I'd like to add is a form that contains a stop button to stop the loop. The problem is that even if I use a background worker like I normally would for a standalone application, it still locks up when Solidworks is processing files. That's just normal operation for the program, the UI freezes when doing a cpu intensive operation such as loading or saving files, regardless of how I write my plugin. So my limited attempts at threading to get a form that won't freeze have been unsuccessful so far.

I have a program that when you set it as the default program for opening rtf files, and open the file, not from the program, but from windows. It doesn't open it at all. It launches my program but, the file doesn't open in my richtext box.

I recently made some obvious changes to one of my programs (added a few buttons, etc), and when I start debugging, it goes back and uses an earlier version before I made the changes.

I want to have a link in an email with an ID number. Then, when the user clicks on the link in the email, it either launches my program, or brings the program to top, depending on whether it is opened or not, and then loads the record for that ID number from the link (the software is a record lookup tool).If I can figure out how to "send" the program the ID, I can figure the rest out.

I've been up for nearly 24 hours now. Trying to program an application for a game I have been playing.I've run in to a problem, I'm not sure how to solve.I have basic knowledge when it comes to VB (college class) so bare with me.[code]My only Idea would be loops to figure out where each of the edited numbers are in the array, But I was looking for something simple.Also, would it be easier to work with the bytes rather than edit them in string form?

I have a StringArray that is filled with line of text and I need to take each array of strings and convert them to byte. How
Dim splitText() As String = TextRead.Split(Chr(13))
Dim byteArray() as string = Byte.Parse(splitText(0))
once I can get one element of the string array to convert to Byte I will put a loop around it for each position in the string array but it says the string format is not correct for the byte.parser.
