Array - When Reaches Line 17 - Skips The Whole Sub And Then Next Breakpoint Is Unable To Be Found

Jun 3, 2011

I'm attempting to run my first program in vb.net and everything works BUT the array.

Here is the archive: [URL]

The problem occurs in the Maps.vb file on line 17 when the assignment of variables to the array starts. When running the breakpoint debugger you will notice that when it reaches line 17 it just skips the whole sub and then the next breakpoint is unable to be found.

May 23, 2011

I've never had to work with them before, and I think I've got everything down except one big thing: I'm setting it up so that different settings have different values depending on what file is being read. I need to know how to tell vb to take a specific item in an array and make the setting equal to it. I know how to make it read the file and add each new line into the array, just need to make sure I'll have to correct method to get the item in the array to match up the setting.

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]...

VS 2008 Class And Read A Line From A File And Add It Into A Listbox

Sep 12, 2009

I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?
