View 1 RepliesRead A Packet Of Data Which Has Come In From RS232
Jan 10, 2010I am trying to read a packet of data which has come in from RS232. I need to be monitoring the port until data comes in to be actioned. I have been doing this fine for some time using the following code:
Dim strline As String = Nothing
Dim comPort As SerialPort
Dim bIsOpen As Boolean = False
[Code]....
The code above works without a problem unles byte 1 or two are greater than 127. Basically, all of the characters that are not converted seem to be 128-255.
I am using VB 2008 express. Clearly I need to read each byte individually and store it as a byte within an array instead of a string but i am not sure how to do this.
how to get around this either through reading bytes properly or through using a different encoding format
Check Packet Size Of TCP Data Before Reading Next Byte In Stream
May 25, 2009I am sending data to server via TCP IP Connection. I am using a continuous loop at the server end - that accepts new clients and while streams can be read, it reads data stream.
The data is sent from the client with 2 leading bytes of data that represent the size of the packet of data sent and type of data.
My question is: how do I retrieve the size of the data packet and then check that this amount of data has been retrieved?

Read The Text In The Memory Address Of The Program?
Jun 22, 2009I need to make a program for my school (I`m the principal), that reads the text in the memory address of the program and write it down in a txt. I already have the address numbers. For more information, I use VS 2008.

Text In The Memory Address Of The Program And Write It Down In A Txt?
Jun 20, 2009I need to make a program for my school (I`m the principal), that reads the text in the memory address of the program and write it down in a txt. I couldn`t find a professional here in my city so, I already have the address numbers. For more information, I use VS 2008. I was trying to make one code to get the memory address, and after I succeed this, I'll make the correct program.

1. It only gets the first 4 bytes(is it?) of the memory address. I want it to get all of them.
2. I haven't discovered how to convert each byte(?) into a character. Is there a function for this?
3. When the program runs, after clicking ok on the MsgBox, it highlights the Next and debuggs:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

View 2 RepliesCapturing International Personal Data (Name, Address, Phone, Etc) ASP.NET
Feb 25, 2010I am looking for the best way to capture and validate US & international personal data. I have to use ASP.NET 2.0 (vb.net) and no 3rd party web services. This are all client restrictions.
The main point of this is I have to toss their data to FedEx for a shipping quote. I think FedEx has a address checker but that web service was not approved in the scope of the project and its too late to get it added.
My current solution is to just let the field be required and free form then before I save their profile check to see if FedEx will return a quote. If it fails then I will ask them to recheck their profile or contact the admin.
