| Summary | 0006351: jvHidControllerClass not working under Windows 8.1 | ||||
| Description | Installed 3.48 with Delphi 2009. Building the BasicDemo and running it results in an error dialog "Device cannot be opened", rendering jvHidController unuseable. | ||||
| Tags | No tags attached. | ||||

Opening the BasicDemo project under Windows 8.1 causes the immediate error "Device cannot be opened". Details: [49D1E465]{JvSystem120.bpl} JvHidControllerClass.TJHidDevice.CtlCreate + $1B1 [49D20007]{JvSystem120.bpl} JvHidControllerClass.FillInList + $147 [49D200FE]{JvSystem120.bpl} JvHidControllerClass.TJvHidController.DeviceChange + $2A |

Previous note still applies but the runtime error in BasicDemo.exe can be corrected by adding an event handler to HidCtl.OnDeviceCreateError as follows: procedure TMainForm.HidCtlDeviceCreateError(Controller: TJvHidDeviceController; PnPInfo: TJvHidPnPInfo; var Handled, RetryCreate: Boolean); begin Handled := True; // eliminate "Device cannot be opened" error end; Maybe a default OnDeviceCreateError event handler should be added to the HID demos? |
