I'm trying to read a text file by use a array for an interactive map. In the text file I stored shop names such as:
Label2.Tag = "test"
Label3.Tag = "House"
When I hover over a label it will display the name in another label such as "lblShowName".
So far I have the array that reads the text file.
dim shopNames() as string = io.file.readalllines("fileName")
I'm trying to read specific values from the text file (below)[code]...
How do I store only the data I require in the array? I've tried split and substring but cannot work out a usable method - I need on the text after the colon for each line.

I have a Comma Separated value file in .txt format... simply put, its a bunch of data delimited by commas and text qualifier is separated with ""For example:
"So and so","1234","Blah Blah", "Foo","Bar","","","",""
"foofoo","barbar","etc.."
Where ever there is a carriage return it signifies a new row and every comma separates a new column from another.My next step is to go into VB.net and create an array using these values and having the commas serve as the delimeter and somehow making the array into a table where the text files' format matches the array After that array has been created, I need to select only certain parts of that array and store the value into a variable for later use.... how to make the array and selecting the certain info out of it..
