I am using C++ GDI, StretchDIBits to draw images on DC.
Because the original Image is large, and high quality is needed.
I use HAFTONE mode, to draw whole image on DC(zoom the image) seems time comsuming.
So I decide to draw partially using StretchDIBits.
But there is a serious problem about StretchDIBits.
I can only draw rect in int...
This is a fun one... I have an application that has a help screen and is displayed as a modal view. The main view has an action that occurs when the device is shaken. I do not want the action to occur (sounds are played) when the help screen has been displayed.
I have tried a few things... here is my code:
To display the help screen...
Apple annonced Shake API in iPhone SDK 3.0. I can not find any information regarding this new feature.

I'm trying to implement the shake "tutorial" on this page, but I think I'm missing something. I copied his accelerometer function into myAppViewController.m file and put some nslogs in there to see if it even gets into the function when I use the simulators "shake" function. Nothing shows up in the debug console.

When I select "Shake Gesture" from the Hardware menu in the iPhone simulator, my first responder always receives two shake events (with a few milliseconds in between).
Unfortunately these two events in the simulator lead to a problem with an UIScrollview that should scroll to a specific position - what it does, but only for the first ev...

Hey,
How is it possible to let some objects fly around and bumb at the end of the view and collide on each other.
The second step would add acceleration of the objects by shaking.
I haven't found a tutorial yet or some step to begin at.

Innocuous enough. We also c...
I'm using PhoneGap 0.8 and I'd like to detect a basic shake gesture. I've found two relevant snippets:

Neither of them are working for me. Unfortunately the documentation seems a little outdated and the API r...

Hello,
after reading some posts about implementing shaking on 3.0, I think I get the idea but I'm not getting any call to the:
motionBegan
motionEnded
motionCancelled
this is an example of what I've read:

I'm sure I've added the

I need to add a shake feature that will refresh my Anroid application.
All I find of documentation involves implementing the SensorListener, but Eclipse tells me it's deprecated and suggest SensorEventListener.

I'm trying to detect a shake on the iPhone device, so for what i've read I need to set my view controller as first responder on the viewDidAppear method. This method is supposed to be called automatically, but for some reason this method is never called. Only viewDidLoad is called.

I'm writing an application for personal use that will track how often I reach for the mouse, and will keep a counter of how long I've gone mouseless. When I use the mouse, I would like it to shake my desktop workspace for a second as a negative reinforcement action.
The application is going to be called WristSlap and will be on github a...
I have a C# game program that i'm developing. it uses sound samples and winsock.

I've read a number of posts regarding how to detect shakes but I'm not sure:
What is currently the best way to detect shakes?
and -

Anyone have an advice, examples/tutorials or sample code?

Hi,
I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController.
In my appdelegate I have the notification (as per the GLPaint sample code):
[[NSNotificationCenter defaultCenter] ad...
