How do I read a line from a database using WHERE? I've read this post but it doesn't really cover it and the forum search throws out the words, 'From' and 'Where' as being common. This is my bit of code but it just skips over it as if it doesn't exist so presumably there's an error, I dunno. I'm trying to read an entire line from the database where it equals the value of 'getweek' where 'getweek' is a variable.

How can I read a text file so that each line in the file is added to a string collection? Also, if I would like to read only the 5th line in the text file, how could I do that?

a user copies multiple lines of text (say, from an email) into the clipboard. Based on my observations, when one tries to paste the text into a single-line textbox, only the first line is actually pasted in. (I am aware that the "obvious" solution would be to set the Multiline property to True, but there are reasons I am looking to avoid this and to put multi-line data into a single line.)
In the TextChanged event handler, I wrote code that parses the clipboard data to successfully convert it to a single-line, comma-delimited format.

View 4 RepliesI 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?
