However, when retrieving the code from a particular line it cannot separate the number from the person's name.will I have to use a new line for every entry, or is there some way to tell my program to differentiate between columns in the code?

View 1 RepliesRead A File As A Set Of Numbers Such As Long Integers?
Oct 31, 2009Is there a correct way of doing this in vb.net? I want to read a file as a set of numbers such as long integers ,say the file contains the string "Hello World - Its a beautiful day blah blah blah" This would read as a set of long integers that are 4 bytes long
ie ascii (hex)
48 65 6C 6C 6F 20 57 6F
H e l l o W o
etc and that would also be an 4 byte word represented as a number 1819043144 thus stepping through the file 4 bytes at a time. Instead of reading and looking for certain words in the file I would look for certain numbers, thus eliminating read errors in certain file types. I coded this type of thing in vb6 before , this would be done with the 'get' method and a file pointer. I have managed to read it a byte at a time with this code but I am unsure where to go with it as the 'get' method isn't in vb.net

Write Listbox Text To Text File And Keep Columns Aligned?
Apr 16, 2011I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?
