How to filter two DataTables in C#? -

-

how filter 2 tables in c#? table 1 contains full data , table 2 contains content of table one?

what want (it's not clear question)? take table1, filter , pass result table2? then:

dataview dv = table1.asdataview(); dv.rowfilter = fexpression; // example "myid = 3" datatable table2 = dv.totable();  // if want typed datatable, can (although there other ways): mytypeddatatable table2 = new mytypeddatatable(); datatable temptable = dv.totable(); table2.merge(temptable);

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
