Oct 1, 2009I have a text file that I'm reading into a listbox. I want to skip a line if it's blank. The following code works if I leave out the check for the line being blank. It puts the file in the listbox with no errors. However, when I include the If statement that checks for the line being blank, I get an ArgumentNullException in the Items.Add line when It gets to the end of the file.

Noob - Remove A Line From Text File?
Aug 18, 2010I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

View 2 RepliesFCL For A Method That Will Allow To Erase A Line Of Text From A Text File And Replace It With Another Line Of Text
Dec 19, 2008I've been looking through the FCL for a method that will allow me to erase a line of text from a text file and replace it with another line of text. Neither the StreamReader nor StreamWriter have a method for replacing or removing Text from a text file, as does the string object. Are there any available methods for erasing just certain lines of text from a file, and then replacing them with others?
In my code, I'd like to locate a certain line in the text file, and then at that point in the text file, use a For...Next Loop to replace each successive line of the text file with new text:
Dim user_data_file As String = "user_data.txt"
edit_input = New StreamReader(user_data_file)
Dim edit_line As String = edit_input.ReadLine
[CODE]...
However, I can't find any methods that will allow me to do this.

Jun 23, 2011I'm reading a text file with StreamReader, line by line. If a condition is met, then I do an operation and then start reading the file again from the first line. I realize I could close and then re-open the file, but surely this would be very slow.
I could do this easily in VB6, but pulling my hair out trying to do this in vB.net. It seems that 'Seek' is the function to use, but it doesn't work.
I've seen other examples, where it works, but you must open it a different way -- with a file number.

Pulling SQL Data Into Text File - Some Fields Null / Blank
Apr 2, 2010I am trying to pull sql data into a text file. The code works just fine, until some new data comes in from lazy employees and a couple fields (used for notes/comments) are now left blank. Originally I've never seen them blank so I didn't think anything of it.
col2 = myreader.GetString(1)
It will error if the field is ever null - I even tried using a case when:
case when note is null then '" & empty & "' else note end and set the variable emtpy = '', but vb still thinks that it's null and errors?
