srFileReader = System.IO.File.OpenText(sFileName)

Read A PDF File Line By Line Using PDFBox?

May 4, 2009

I am trying to read a PDF file line by line using PDFBox.This is the first time I have ever attempted to do this with a PDF so I am not sure what I was expecting but I thought I would end up with some "mark up", which I could use to parse the lines I was looking for out of the file.

Anyway it didn't work out the way I had planned and I am not sure if that is because I am using the wrong tool or not using the right tool correctly.I managed to extract the text but I didn't really see any mark up that would be usefull to parse the file. Does anybody have any experiece with extracting test from PDFs. What tool(s) do you recomend?

Read All Txt File In A Folder Line By Line?

Mar 29, 2012

I am quite new in VB NET, after VB. and unfortuantely I had to copy paste and merge the code fragments from some tutorials.

I have a folder including 200 eng files which can be opened by notepad. And each file has around 4000 row; with 60 field seperated by coma. I need to read specific row-field value at each files.

Now what I can is:

a) reading individual txt files and find specific value

b) listing all of the files in the folder

c) I can merge (a) and (b) and read all the files automatically, but since ram is continuously increasing, and at one point (sometimes 163, sometimes 169, or 170. files or something) it gives an error as "System.OutOfMemoryException". My ram is 4 GB and when I get this error the ram is increasing to more than 3 GB.

1- Could it be happen because of being eng files instead of regular txt files?[code]...

Split A Text File So That Each Line Does Not Exceed 50 Characters?

May 23, 2012

I am reading a text file with mostly alpha characters. the content is not really relevant but the size of each line is very important. The process I will feed this text to will require each line be no more than 50 characters. So I will pre-process the text and add line feeds to make sure that happens.I tried several VB.NET regex like ^.*$ but that doesn't really break up the lines by 50 characters. I would take the result and iterate through each match and then cut it up and write it to an object in memory. Can this be done with a single regex pass?Otherwise I will use a streamreader and on each line check the length and if <=50 write it out with a streamwriter. if >50 cut it up in sections of 50 and then use streamwriter.

A brief example of my text:
119 SMITH KATY AAAA F ZZZ X NB SX ET
MILES,200/LM450
