I am not very familiar with VB.NET so I don't know if this is possible.Some code I am working on is setting the properties of a very large class. In the setter of each property an event is raised to indicate that the class data has changed. An event handler then serializes the instance of the class to a database.Obviously I do not want this to happen after each property is set, so I need to either have a delay before saving, or something else.I am keeping a large list of instances in a cache implementation already, so one option would be to only process the cache every now and then and save all unsaved instances in cache to the database.So I tried to see if I could derive a class from Application (and override DoEvents), but it is NotInheritable, so no luck there.

View 3 RepliesIs there Any way to handle the crtl + Alt + Del Key combination. Take for instance in a quiz application (Win Forms ), the user should not be able to switch to other windows till the test is over.
I'm able to capture the ctrl and alt key strokes individually, using c# standard properties. but once they user hits the del key . The control goes out of my appliation and windows handles it.
Ok, so I'm writing a basic windows form application in VB.net as you do and need to be able to raise keyboard events based on data received from the serial port. I'm able to receive the characters that I want (lets say a lower case c) and display them. Its also easy enough for me to find the keycode. What I want to do though is tell windows that key "c" has been pressed. The application is paired to a bluetooth terminal, I wanted to have the experience of writing the code behind this myself rather than using another library although it seems I've failed already. How would I go about doing this?
View 1 RepliesI am using VB code in VS2008.Net3.5 and Windows Mobile SDK6 to develop my Device application. For each form, I can see a deafult keyboard on my Handheld application screen.

View 1 RepliesI am building an image processing program. As part of this, I have a picturebox, set to AutoSize.
When I load an image larger than the size of the picturebox's container the box automatically expands and shows scroll bars. This is what I want. I can scroll the picturebox using the mouse to click on these, but I would like to be able to scroll the image using the arrow keys. This poses a couple of problems:
1) finding what properties to change or events to raise when a key is pressed. It is a property of the picturbox, or a property of the container?
2) dealing with repeated scrolling while the arrow keys are held. I know I can use keydown to detect that an arrow key has been pressed, but how do I continue to scroll as long as the key is held down?
How do I change the keyboard inputs when a button's held down.Example: When SpaceBar is held down, if letter Q is typed P will the input instead.
I've tried KeyDown / KeyPress but that doesn't seem to be working
I want to press for ex: "F12" and will show for ex: "msgbox".I know how to that with keydown but I can't use this outsite my application..

View 1 RepliesI have been working on a project for some time now and I am stuck. I am trying to sense when a navigation software speaks so i can mute the volume of everything else on the computer.
my problem is that i cant properly sense the audio of the software. i am using windows 7 and vb.net. i have done a good amount of research, but i have not come up with an answer.
i am almost positive that i need to intercept the win32api call of the software to trigger the mute that i will use. i dont know how to do this, all the information i can find that is even close to this subject is for 98, nt and 2k.
does anyone know of any books (or websites) that contain information on this subject?
how to do basic keyboard movement in VB 2010 express. i'm making a very small, simple game (as this is my usual method to self-teach a language) and i'm still getting a grasp of events. if someone could direct me to some place i could learn about this (and preferably not a "paste this code in your form") something simple as moving a picture box or what have you across a form would be great.
View 3 RepliesI'm new in the programming area and I'm having trouble making a calculator. My question is: How do I make the calculator work using only the keyboard, without the need of mouse.
I tried this:

Me.KeyPreview = True
End Sub
Private Sub FlowLayoutPanel1_KeyDown(ByVal sender As Object, ByVal e
As System.Windows.Forms.KeyEventArgs) Handles RESULTADO.KeyDown
If e.KeyCode = Keys.NumPad0 Then

It only works on the text box called Result. I want to know how do I make work in the whole Class, and if it is possible, to make it work on two different Classes without writing twice the same code.
So I had this idea to make a virtual drum set and my school book doesn't have the answer for me and I haven't been able to successfully google this.

Is there a way in vb.net to subclass/hooking in to any controls scroll bar and change it is colours etc (I saw this once in C++ but lost it).
