I'm declaring my hardcoded (specialfolder)path to the database public, but I want to read the path (not the complete string) from an XML file.Dim strConn as string = New SqlCeConnection("Data Source=" & >> path from XML<< & "database")The problem is that I need to open the XML first, before I can read the descendant.[code]Dim appXML = xelement.load(xmlPath)msgbox(appXML.descendants("db_path").nodes(0).tostring[code]

View 1 RepliesI have a text file with an unknown number of lines. I want to read this file line by line and send each line's text in a check list box. But how am i gonna do that when i don't know how many lines exist in text the file? [code]The code above reads only the first line. I tried to do it as in vb6 using while not eof(but here i don't know what to write cause my file isn't opened in a certain channel).

I would like to make. If you click like the secondary button it pickups secondary from Link.txt and navigate to it.
Basically what I want to achieve with this code is to read the text file and import the corresponding line to its textbox. But when i run this code BUT_A.text returns the value that is set for BUT_B on the textfile then any code after that doesn't import at all. Here's the code I am using for the open button (I'll be adding a OFD later)

I am reading in a line in this format: AL93895200 How do I get each of the items in the line that are separated by a space. I think it should go something like this:
Dim line As String = fileReader.ReadLine() Dim fields() As String = line.Split(How do I get it to split at the spaces?)
But as you can see, I don't know how to actually get that to work.
My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.
View 7 Repliesim making a game that reads text files off of an ftp server. everything is working great. except for the fact that i cant read more then the first line of the players text file. how would i use substring to, for example, look for 'inventory' and get all the info under 'inventory' and above the next title?
View 1 RepliesOkay, so I've been looking on the web for a way to read only ONE line out of a text file. Recently I've gotten by by creating separate text file for each line (such as a text file named, "Username", another named "Password", instead of creating a single text file with both the user name and password.) Now I am faced with having to do this. I want a quick and easy way, VB won't let me do open file as input #1 for some reason. I just need the second line of text out of this text file. What is the quickest and easiest (and painless) way of doing this?

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?
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.
