I 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.

i have a small program to run through a log file and extract data from it which works, but the array it puts out has a blank value before and after the actual data values, and it confuses me why that happens, i dont really understand why and was hoping someone here knew! the parts of the code related are below
Dim rgxSessionStart As New Regex("^Session Start: [A-Z][a-z][a-z] ([A-Z][a-z][a-z]) (dd) dd:dd:dd (dddd)")
Dim substrings() As String
substrings = rgxSessionStart.Split(LineIn)
a sample line that it would match is Session Start: Sun Aug 22 00:00:00 2010 which WORKS, but the values of the array are "","Aug","22","2010","". so its not a critical problem because i can still get the data from it, but those blank values are puzzling and i feel like maybe im doing something wrong with the syntax or method for them to be there.
I have an rdlc report that always produces the last page in blank. In this page, the header and the footer are printed but no data is shown (all data finishes in the previous page). I already checked and re-checked the horizontal and vertical printable areas and all the report definitions fit into these areas (if not, a blank page will be produced in between each page, I guess). If the report has one page, two pages are printed, if there are ten pages with data, eleven pages are printed

I have created an XML file using streamWriter.. Now, i want to remove the line breaks in my XML file.. Is there a way to accomplish this task.
[Code]...
I 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 1 RepliesI have a program that uses a richTextBox to append and save file locations. Each line in RichTextBox1.Lines is added to a listbox for the user to see the files. The format of the richtextbox output is shown below:

I have a button on the form which can remove an individual file from the ListBox with the code shown below. The problem I am having though is that the RichTextBox text is ending up formating like shown below. If I remove the C:UsersJordanDownloadsfile.ext for example, the RichTextBox text will show as:
<vbCrlf>
