c# - Update specific cell of excel file using oledb -

-

i want update specific cell of excel file using oledb. i7 cell, reason i1 getting updated. can tell me what's wrong code?

oledbconnection oledbconn = new oledbconnection(connstring); oledbconn.open();  // want set value of i7 cell 22, reason value i1 getting updated :( oledbcommand cmd = new oledbcommand("update [" + sheetname + "$i7:i7] set f1=22", oledbconn); int result = cmd.executenonquery(); console.writeline(result); oledbconn.close();

this may purely issue cell address scheme you're using. try $i$7:$i$7 intsead. also, f1 thing in query?

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
