crash - How do I get TWebBrowser in Delphi XE2 to run? -

-

the twebbrowser component in delphi xe2 seems buggy. there sort of code have run in order instantiate in special way?

  1. create new delphi project
  2. drop twebbrowser component onto form.
  3. in form1.formcreate() call webbrowser1.gohome (to google).

if compile 32-bit , go specific webpages error messages. google (ncbi nucleotide blast) , click first link.

in addition these javascript errors if click link opens in new window, opens in ie (a separate application).

the 64-bit version seems more broken. going same site (ncbi nucleotide blast) entire program crashing due 'divide_by_zero' error.

regarding floating point exceptions, twebbrowser expects operate floating point exceptions masked. looks using delphi default floating point settings , have exceptions unmasked. suspect if mask exceptions problems disappear.

do so:

setexceptionmask(exallarithmeticexceptions);

and others have said, silence javascript popups setting silent true.

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
