android - Launcher intent behaves like back button -


When I call intent / 

  if (parentIntent == null) {parentIntent = activity.getPackageManager (). GetLaunchIntentForPackage (activity.getPackageName ()); } NavUtils.navigateUpTo (Activity, Parentmont);

The following code works though: 

  if (parentIntent == empty) {activity.startActivity (activity.getPackageManager () .getLaunchIntentForPackage (activity. GetPackageName ()) .addFlags (Intent.FLAG_ACTIVITY_CLEAR_TOP)); Activity.finish (); } And {NavUtils.navigateUpTo (activity, parent intent); }

Nobody knows why NavUtils behaves this way?

documentation quote: 

  NavUtils.navigateUpTo (activity source activity , Intent upIntent);

Navigate to the activity specified by the attribution from the source activity, complete the source activity in the process.

Then, NavUtils.navigateUpTo press a back button, and if you are calling the first piece of code from the Home button click listener, you will be taken back to the previous activity.

c++ - How to load a bitmap from file into the samples buffer -

I am trying to add text to the bitmap obtained from the DirectShow filter. First of all I tried to use gdiplus, but that was not working so now I just call a net program that connects to bitmap. The problem is that I do not know how to reload the bitmap from a file into buffer samples in a direct save. Here is my code: Bitmap BMP (640, 480, 2560, 1379773, Newbuffer); // save clsid pngClsid; GetEncoderClsid (L "image / PNG", & amp; pngClsid); WCHAR * file = L "D: \\ temp \\ sample.bmp"; Bmp.Save (file, & amp; pngClsid, NULL); Std :: string command ("D: \\ yourcontrol \\ bitmapDraw.exe D: \\ temp \\ sample.bmp \" test text \ "D: \\ yourcontrol \\ out.bmp"); // Heripal system (command.c_str ()); // Load Bitmap BMP 2 (D: \\ Your Control \\ Out.bmp); How do I forward bitmap from file to sample? Media samples are a part of the agreement between filters on specific pin connections. You usually do not load media samples until y...

javascript - How to get MySQL query result returned using $.ajax -

To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
