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 The difficult part is that the file is of part numbers and some of the products are superceded by other products (which can also be superceded). What I need to do is follow the superceded trail to get information I need to replace some of the fields in the row I am looking at.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]....

I'm trying to write data to an INI file, I've got some code to read it: url...I've tried to modify this code to get it to be able to write to INI files, but I haven't had much success.I know there are DLL's designed for this, but I would like to have my application so it can be distributed as a single EXE.Also, I know there is My.Settings, but I cannot use this, as this INI file is used by another application, that I have not developed.
So, I was wondering if anyone could help me modify this code to write to an INI file, something like WriteIniValue(IniPath, Section, Item, Value)

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.
