c# - Toolstrip.Items.AddRange(ToolStripCollection) has odd behavior -

-

part of application i'm working on involves dynamic toolstrip items added , removed depending on application's state. i'm storing items in various independent toolstrips , adding , removing them when necessary. problem i'm having this:

-if new toolstip has 1 item , use method addrange, it's removed new toolstrip, giving item count of 0.

-if new toolstrip has multiple items , use addrange, argumentoutofrange error thrown.

is there toolstripitemcollections i'm unaware of that's causing this, or there better way go programming this?

edit: quick example code

toolstrip oldtoolstrip = new toolstrip(); toolstrip newtoolstrip = new toolstrip();  newtoolstrip.items.add(new toolstriptextbox()); newtoolstrip.items.add(new toolstripbutton());  oldtoolstrip.items.addrange(newtoolstrip.items);

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
