View 5 RepliesI 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..
Some binary files have application variables at the end if you open it with a text editor you can see these variables.
