View 4 RepliesI am creating a program in Visual Basic 2008 and I would like it so when I check a check box, the word that corresponds with the check box (in the code) will show up in the text box. So if i had one check box that said, Hello. Whenever that check box was clicked the word, Hello, would show up in the Text box. And then if I checked another check box, Bye, the word Bye would show up right below Hello. So it would look something like this.
Hello
Bye
But whenever I unchecked the check for hello, the word hello would go away and Bye would move to the top of the text box.Here is the code that I have so far. I can make the words appear in the text box but not at the same time in the list.

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged

I have a basic bubble sorting algorithm that can sort either A-Z or in numerical order with just the change of a "less than" or "more than". However, I have to use the code twice in order for it to sort correctly.
'Sub Sort(ByVal array As Object)
'--A-Z
If Array(i) > Array(i +1) Then
[code]....
Anyway, if there is a way to do it, that'll allow me to have just one sort instead of having two sorts which use the same sorting algorithm, but just a different comparator.

View 4 RepliesHow would i go about checking a file extention to see if it is either
'.exe' or '.ex_'
What i need to be able to do is that if the extention of the file is '.ex_' then that file is copied to another folder, or if the file extention is '.exe' then it is passed onto another routine that will compress is.
Baring in mind that there could be a number of files in that folder.

I have a list box on the form which functions as a copy/paste. When you copy something, it is automatically added to the list box as a "clipboard helper". Here is the problem,however: if the text is more than 1 line, the list box does not show all the text.It ends up looking messy.So getting back to my question, is it possible to make the list box item height for an item depending on the amount of lines that item contains?This is a one line sentence in the list box and should take up one line.This is a multi line sentence in the list box and should take up two lines for item height.
