View 6 RepliesI have formA.vb and I added some shortcut keys using the key_up event handler. Before coding the handler I change the keypreview property of the form to true. I added this code :
Private Sub IntRMA_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyUp
If e.KeyCode = Keys.ControlKey And e.KeyCode = Keys.C Then
[code].....
I have a problem detecting whether one of the arrow keys is pressed, all the other keys seem to be detected apart from the arrow keys??? I have set key preview to True........ It detects the arrrow keys BUT ONLY if I have NO other controls on the form??? example..
Me.Text = e.keycode
It works, but then if I add a button for example, it stops.
just wondering how i could give my auto typer hot keys, for example they press f1 to start the typer f2 to stop it.

I'm trying to create a shortcut which expands or collapses my treeview using the ctrl+alt+up-arrow or ctrl+alt+down-arrow:

End If

How could I loop through a list of the keys that are available in the 'Keys' enumeration? It seems like it should be something easy to do, but I'm not having any luck finding a collection that I can loop through.
View 6 RepliesSo I found this little morpg. The game is fun but really repetitive. I would like to simplify some of the tasks in the game. I do not know how to start this project. How can I recored arrow keys and then tell the computer to enter the arrow keys? One of the objectives in the game is to run around a farm 2x and scare away any wolfs. So the commands would be "arrow key up" for 30sec and then "arrow key right" for 4 sec and repeat. I have worked with robots in real life for some time. We would fill arrays with such instructions. One of the most fun things to program! But I have no idea how to do this in VB.
View 12 RepliesI need to capture the left and right arrow keys in Form1.KeyDown event so I can use them as hot keys. Instead they seem to be assigned to tab order (move focus to previous/next control) and the KeyDown event never gets called. How can I remove the arrow keys from tab order and use them for my hot keys instead?

I want to bitwise turn off the left most bit of a Short value (&H8000) and leave the other bits as they are.
Dim x = BitConverter.GetBytes(Short.MaxValue Or &H8000)

Isn't there any shorter way with bitwise operators?
When I do
Dim a = Short.MaxValue Or &H8000

View 1 RepliesI have a date field in my Access database that I want to display in a textbox with a colored back color. This is VB.NET 2008. A datetimepicker has a format property (short) but the datetimepicker does not allow the color I want. No problem, it's just for display so I'll use a textbox. But the textbox shows the date and time. How can I get rid of the time in the textbox and just have the date? The field in the Access table is Date/Time with a format of Short. I think Access always stores the time.

We had a Nullable object must have a value error today on this line of code:list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= barDate
Funny thing is that I feel sure this used to work fine (and there has always been a sprinkling of null values in the underlying data). And logically it looks fine to me. The check for HasValue and the AndAlso look as if they're going to shield us from any Null danger.But it seems suddenly they're not. Am I missing something?OK, we can correct it to this, which eliminates the error:
list = From x In Me Where If(x.FooDate.HasValue, x.FooDate.Value.Date >= barDate,False)
But this looks to me less readable. In simplifying the above code to shorten the line I left out a crucial chunk of the code. The original problem should have read something like:
list = From x In Me Where x.FooDate.HasValue AndAlso x.FooDate.Value.Date >= fromDate And x.FooDate.Value.Date <= toDate
Because of the rules of shortcircuiting and operator precedence (as outlined in an answer to a long ago question of my own) I needed to add brackets round the second part of the instruction in order to stop LINQ evaluating the second x.FooDate.Value.Date:
list = From x In Me Where x.FooDate.HasValue AndAlso (x.FooDate.Value.Date >= fromDate and x.FooDate.Value.Date <= toDate) LINQ really does obey AndAlso and force me to look more closely at the original problem.
