i have this line of code to catch an exception if a letter is inputed, or if it is out of rang as a number, but I have added WHEN to avoid catching numberical data. Now how can I use an exception error to use it before my case statement in order to avoid running the code twice, cause once the case codes has been through it will run a clear txtbox which is already taken care by the try catch, don`t if thats clear for you but i understand it. here is the code in parts...
Try
'Integer Levels: intLvls is egual to the assigned text box, the first one from
'the top, this line of code allow the user input to be captured into a variable.

I'm looking for a library for Autocomplete support in text controls which remembers all previous entries of the user and provide auto-complete support for it.For example for "recent files" I use [URL] and it works great. Do you know something like that for this purpose?
UPDATE : This is a .NET Winforms application and I'm using normal Text Control.

I am trying to create a way to use my arrow keys to move around some text boxes. The form has 12 textboxes moving from left to right with 4 in each row. Tab Index will be like this.
0 1 2 3
4 5 6 7
8 9 10 11
In the code I have figured out how to find the current tab index but I am having trouble moving to the next control based on which arrow key is pressed. Here is the code I have so far.
Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean
'This variable holds the current tab index for the control that has focus.

How do I do this? If I cut and paste, then it wipes the code, sometimes the stuff doesn't even show up when I run the program (I guess it's loosing all the handler information) I read about not cutting / pasting controls in the sticky at the top.

As you can see from the code below there is a lot of repeated code. I want to move that code outside the if statement as it's performed for each if, but the Dim employees variable I'm declaring is causing my issues. I don't know how to declare the variable outside the if statement as it's a linq-to-sql query, so I can later define it within the if statement. I can't access employees outside the if statement, so I can't just put the repeating code outside the if statement.
Private Sub btnFindEmployee_Click(sender As System.Object, e As System.EventArgs) Handles btnFindEmployee.Click
If chkSrcEmpID.Checked = True Then

I am creating a bulk media converter. In order to do this I need to go through each line in a list box one after the other and run the conversion function. I am trying to use the following:
For Each item In listVideos.Items
conversion code
Next
However this makes the program want to convert all videos at the same time... is there anyway to get the program to convert one video and then after the conversion code is completed to move to the next one?Should also be noted that I am using FFMPEG for this project.
