How to define a recordset when using text data

[SystemShock]

Hi,

I have looked all over and cannot get my head around the following. I hope someone here can help.

I'm making a program in MS Visual Basic 2010 Express that will read a text data file and write the entire file to a text box. The data in said text box is then manipulated. These changes affect the entire data so I got that part done. The issue I have now is that I want to split and sort the data but need to define a recordset before doing so.

The records in the data are variable length (lines). There are characters that distinguish the start of a record. I want to be able to add the text of a entire record to another text box and use buttons to step through the data.

Here is a sample of what the data looks like.

SC000000
SA02-Oct-2015
SA02-Oct-2015

SK
SKSome text added here
SKSome text added here
SKSome text added here
SKSome text added here
SK
SKSome text added here
SC000001

SK
SKSome text added here
SKSome text added here
SKSome text added here
SKSome text added here
SKSome text added here
SK
 

One can see that the start of a recordset is SC00 etc. Also note that the records, as mentioned before, are variable in the length of how many lines they contain. The data can also be in excess of 500 000 lines.

Any suggestions/help will be greatly appreciated. I have not coded in VB since school days and allot has changed since VB6.

Regards,
