I have an access database, which I connect it to the form I have text boxes which displays info from the fields in the database. I have created a "Next", and "Previous" button, this is my code
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?

if this is not the best forum for this since this question is about using Visual Basic to do some Excel specific stuff. Here is what I have and what I want to do.
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.

I commented the area where I haven't been able to figure out how to code it. I have spent a few days working this out and have spent the past 6 hours working on this part.
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
In the "old days" I was working with Linux to create C/C++ programs (really really BASIC...HA!...programs, just learning to program in the courses as an intro) by creating a text file with the source code that was then fed to the compiler/linker that then spit out the executable binary.
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.
What does this error mean? I havent modified anything in the designer code, but its giving me an error? WithEvents variable 'Move' conflicts with event 'Move' in the base class 'Control' and should be declared 'Shadows'. The error relates to Friend WithEvents Move As System.Windows.Forms.DataGridViewCheckBoxColumn

I have a program in VB2008 and I need to execute a thread from differents Subs.Each time I start the thread I want to cancel the previous.Here an example:
Private Sub TextBox_Changed(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim ThreadResults As New Thread(AddressOf ShowResults) ThreadResults.Start() End Sub Private Sub ckBoxAllRecords_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ThreadResults As New Thread(AddressOf ShowResults) ThreadResults.Start() End Sub
I write in a textbox, TextBox_Changed fires, thread spend 4 minutes filling a dataset I check a checkbox, ckBoxAllRecords_CheckedChanged fires, thread spend 10 seconds filling a dataset.I dont want anymore the dataset of TextBox_Changed so I want to cancel its filling.
