I am reading a txt file and displaying the contents into a listbox but it generates an empty listbox item at the bottom of the listbox. I am splitting the textfile each time it finds a new line in the txt file;
.Split(vbNewLine)
The problem there is always a blank line in the txt file at the end and so generates a blank list item. How can I remove this blank list item from the listbox? Is it best to try to remove the blank line from the txt file first or the empty list item from the listbox after the file has been read?

View 7 RepliesIm trying to work out what the best way to match 2 strings together, but with a difference.
String1 = "dog cat bird chair book table"
String2 = "the dog chassed the cat around the chair"
No I know I can break string1 up by space character and check if each word appears in string 2, I would prefer to not have to do that.If there some sought of regex that would take a group of words and retrun how many of them matched ?
I'm adding text string into a list box together with data retrieved from text box, and I wanna bold that text but really don't have any idea how to do so.

The user will click the book name in the combo box.
Note: The combo box is separate from datagridview . It is not part of datagridview columns.
Then the datagridview for Issuing books i.e. with the columns bid,bname,aname,data of issue,date of return should be displayed.
The row that will be displayed in datagridview is such that the bookname selected by user in the combo box should match with bname row .
On the same datagridview there will be button with name "Issue" so once it is clicked then this whole data of datagridview should get stored in the database table name "Issue" and get deleted from the databse table name "MBA"
I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?
