Screen capture delay due to writing data in the file
I think it is not possible as pointed by mah as well. The code below will help you keep the app responsive while you are writing the image in memory. This is because the UI/main thread is busy in writing the captured screenshot in memory. So the easiest way to solve this issue is AsyncTask. public CaptureScreenShot extends Activity { ArrayList<bitmap> arrayListImage; int i=0; pub

How to add items to a List Control in an MFC dialog
First, make sure you chose the Report option of the View property of the List Control in the Resource Editor. I suspect that you are using the default Icon view, which is not what you want. Then, you need to add the required columns: m_lstIDC_LIST1Control.InsertColumn(0, _T("Full Name"), LVCFMT_LEFT, 90); m_lstIDC_LIST1Control.InsertColumn(1, _T("Profession"), LVCFMT_LEFT, 90); m_lstIDC_LIST1Con

OpenGL in Java, Manual creatation of gluLookAt matrix
OpenGL uses column-major matrices. You appear to be filling your matrix row-by-row, this would actually work in Direct3D (row-major) FYI. The simplest solution would be to call mLookatMx.transpose (...) (if you were using a proper matrix class); this would flip the rows and columns for you. However, since you are using a plain old FloatBuffer, you need to put (...) the contents of your matrix on

Getting java.lang.NullPointerException when calling Method.invoke
The parameter that you pass to invoke must be an object on which the method is invoked, unless the method is static.

During the KMP algorithm, you are, actually, counting nearly the same values as in the ta
