Any notes on the velocity or vigorousness with which the window would get shaken?

As for the checking if it was shaken, you may want to check if the window is within X pixels of it's original location.

ResizeStart and ResizeEnd should work good.

Thank you for the advice Ninja-The-Nerd, I'm a little confused as to why I would need to use ResizeStart and ResizeEnd.. Aren't they only for when the form is resized? Or am I wrong about that?

Well, The shake needs to be quick. Kind of like when you have to shake a Juice bottle before opening it.

ResizeStart will only fire when the user starts to drag the edges (or you use the keyboard "shortcut" of alt+space, s, and arrow keys) and ResizeEnd fires when the user lets go.

How to determine whether it was a shake or not, I would judge if the average velocity was, um...
If the user was moving it one way then the other then...no, ehh
On reflection it might be wiser to simply check if the window is within, say, 20 pixels of it's start location.

ResizeStart: note the position, start the timer.
ResizeEnd: stop the timer, compare the position, execute the function.

Edit.
In fact, just ignore this.
It's late, I've been coding for several hours. I failed to notice that resize != move.

I'll just get my coat and leave...

~~Hmmm... Good work Ninja! That was very easy to understand and helpful. I'm workiing on it now and will post the code here once I'm done. Thank you~~

Edit: Hahaha, sounds like you need some sleep :P Thanks for your help anyways, it was much appreciated. Big Grin | :-D

OK sorry for the previous ludicrous suggestion.

I once had a borderless window, and to handle the movement, I had added a button which, when dragged, would take the window with it. I know you're trying to reduce clicks but this could work.

MouseDown:
- set "moving" to true
- store mouse-coords in "lastLoc"
- store window position to "startPos"
- start a timer

MouseMove:
- if moving,
- move window by delta (current location - lastLoc)
- update lastLoc

MouseUp:
- set "moving" to false
- stop the timer
- compare startPos with current position, etc.

That's okay Smile | :)

Thanks for the quick replys too Smile | :)

I got a little confused with the mouseup parts since i have a bordered form so i changed it around a little and it actually works. the only problem is that you need to ensure that must stop dragging the form before you release the mouse button Frown | :(

lol. Here's the code:

private int shake = 100;

private void Form1_LocationChanged(object sender, EventArgs e)
{
    progressBar1.Enabled = true;
    shake = 0;
    timer1.Enabled = true;
    timer1.Start();
}

private void timer1_Tick(object sender, EventArgs e)
{
    if (shake <= 10 && progressBar1.Value >= 5)
    {
        timer1.Stop();
        progressBar1.Enabled = false;

        if (Tc.TabPages.Count != 0)
        {
            while (Tc.TabPages.Count != 0)
            {
                Tc.SelectedTab.Dispose();
            }
        }
        else
        {
            AddTab();
        }
    }
    else
    {
        progressBar1.PerformStep();
        shake++;
    }
}

Edit.
The logic in this code is a little conveluded, so message me if it requires explaining :P

Nope, I get it. After many re-reads... :P

What's timer1's Interval set to?

You could try to determine if the location has changed since the last Tick event. If it hasn't, the drag is over and it should just tidy up/do nothing.

I'd try just now, however that sleep I hoped for is beckoning.

I've two classes, here is an example of 'em

class A
{

string prop1;
public string Propery1
{
set { prop1 = value; PropertyChanged(); }
}

protected vitual void PropertyChanged()
{ }

}

class B : A
{
A instanceOf_A; // will be initiate in constructor

protected override PropertyChanged()
{

}
}

now, I want that when any property(of base class) of B changes then it should change the same propery of instanceOf_A. I can do this if I pass a property name as param from every property and then change value using PropertyInfo in PropertyChanged. But I was wondering that is there any way to know which property changed or which property called PropertyChanged, something like callstack...

Is this required? B is derived from A and when B is instantiated, A will also get instantiated.

yes...its for keeping the actual data in it so that it can be retrieve when require. In the previous version of that class I used a physical file to keep the data but now I need it in class.

Doesn't the PropertyName property of the PropertyChangedEventArgs class gives the name of the property thats changed?

It's not necessary to be so stupid, either, but people manage it. - Christian Graus, 2009 AD

yes but it needs to be initiate from every property with PropertyName and I think thats the only way Frown | :(

I wonder how can i convert 0x10 to 0x11 inside the array. I need u guys help.

byte[] data = {0x47, 0x55, 0x03, 0x10, 0x00, 0x81, 0x00, 0x0b};

Hi,

you may want to ask a clear question, that should help in getting a clear answer. as my sig says.
Most of us aren't very good at reading someone's mind.

if your problem were that you want your program to behave differenly each time it runs, you need to persist some state outside the process, maybe in a file, or in the registry.

Smile | :)
