View 5 RepliesI have an issue where I need to load a fixed-length file. Process some of the fields, generate a few others, and finally output a new file. The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at. So how can I best handle about 200000 lines from a file and the need to move up and down within the given products? I thought about using a collection to hold the data or a dataset, but I just don't think this is the right way.[code]....

How can i create this ? i want trying with data set but getting problem
I am having problems writing correct data to a file. I create a string of characters (approx 5000 bytes long). The string is a mixture of text characters and numbers converted to bytes. I then:
a) write the string to a readable text file
b) display the string contents to the console
c) write the string to a file - BDF.bin (I tried both IO.BinaryWriter and IO.StreamWriter but get the same error)
The byte pattern for the text readable file and the data displayed on the console match and for the most part , data bytes in the StreamWriter file are correct (first 4096 bytes are OK) but there are some extra bytes and some wrong bytes.Here is a comparison of byte patterns (hex values character written to the file) starting at byte 4096
Console: 45 44 52 31 00 00 00 00 01 00 00 00 90 01 00 00
Binary File: 45 44 52 31 00 00 00 00 01 00 00 00 C2 90 01 00
The byte patterns match, however in the binary file, there is an extra byte (C2).To display the console data, I read one character at a time from the string and display it using hex(asc(mid(string,i,1)))I view the binary data in the BDF.bin file using a hex editor program. I even tried 2 other hex editors and all showed the same byte info.

I'm trying to "convert" an Access DB to a stand alone application. I have under estimated the differences between VBA and VB. Although I have many questions, I'll focus on this topic first.
The Access DB collects and maintains SNMP traps from a radio station. I import CSV files from a remote Unix server via FTP, parse the text line-by-line, and add to a table as a new record. So far, I can parse the text and add to a dataset but I want to write directly to the data source. I also need error handling that will trap errors for duplicate records. There is a Reconcile function that ensures that all lines in the CSV files are added to the table before the files are permanently deleted. Here's what I have so far:
Public Class clsRnm
Private msTrapTable As String
Private moTrap As clsRnmTrap

i need help with stream writer, i can get it read lines and stuff like that but now i need Streamwriter to write to a colour.txt file (already populated with data) and insert a line that isn't already in the file, into alph order eg combobox reads and displays list from txt file.
their is a colour thats isn't in the text file, so i would like it to take the colour from the combobox that was typed in by the user and place it into the colour.txt file in alphabetical order (these are car colours so their are 100's and 1000's per manufacturer, its not as basic as i want red blue black lol) i was able to find loads of data about streamreader but not so much about stream writer
