如何在WES2009 disable訊息視窗(Message Box and Balloon Pop-Up)

Message Box and Balloon Pop-Up Interception

如每次在插入新的硬體時，都會出現以下新增硬體精靈視窗，要如何將新增硬體精靈視窗關閉?如何在之後插入新硬體時，不會跳出此視窗，這時我們需使用Message Box and Balloon Pop-Up Interception。

可以參考以下的三種作法。

方法一：

Suppressing Balloon Pop-Ups (Windows Embedded Standard 2009)

Balloon pop-ups typically appear when new programs and hardware are installed, when disk space becomes limited, and when tools such as .NET Messenger are included in a run-time image. If you do not want balloon pop-ups to appear in your run-time image, you can prevent them either by changing the settings of the User Interface Core component, or by setting values in the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced registry key.

By setting registry values, you can choose which balloon pop-ups to suppress. You can prevent all balloon pop-ups appearing by disabling the EnableBalloonTips registry value. You can prevent just the "New programs installed" balloon pop-ups appearing by disabling the Start_NotifyNewApps registry. These registry values are not included by default in most run-time images and must be added.

To suppress balloon pop-ups by changing User Interface Core settings

1.          In Target Designer, open your run-time image configuration.

2.          In the configuration editor, expand the node for the User Interface Core component and choose Settings.

3.          In the details pane, on the User Interface Settings tab, clear the Show Notifications on Task bar check box.

To suppress balloon pop-ups by setting registry values

1.      In Target Designer, open your run-time image configuration.

2.      In the configuration editor, expand the node for the SLX file, right-click Extra Registry Data and choose Add. The Add an Extra Registry Entry to the Configuration dialog box appears.

3.      In the Root list, select HKEY_CURRENT_USER.

4.      In the Key name box, type Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced or choose Browse to navigate to that location.

5.      In the Value name box, type one of the following:

o    To suppress all balloon pop-ups, type: EnableBalloonTips

o    To suppress only "New programs installed" balloon pop-ups, type: Start_NotifyNewApps

6.      In the Type list, select REG_DWORD.

7.      In the Value box, type 0.

For EnableBalloonTips, the value 2 enables balloon pop-ups and the value 0 disables them. For Start_NotifyNewApps, the value 1 enables balloon pop-ups and the value 0 disables them.

8.      In the Description box, type a description for this registry value for future reference.

9.      Choose OK.

Note:

When EnableBalloonTips is disabled, enabling Start_NotifyNewApps has no effect.

方法二：

Enabling Default Reply (Windows Embedded Standard 2009)

User32 provides the functionality to intercept every MessageBox function and automatically choose the default button. Not all message box windows are produced through the standard MessageBox function; therefore, this feature might not operate on all windows.

To instruct NTUSER to intercept messages, an additional key and values are required in the HKLM\System\CurrentControlSet\Control registry key. You might need to create the registry key and values on your system, as follows.

To set up your system to automatically reply to a message box without displaying it

1.          In the HKLM\System\CurrentControlSet\Control registry key, create a new key named Error Message Instrument.

2.          Under the Error Message Instrument key, add the values of type REG_DWORD from the following table.

Value	Data	Description
EnableDefaultReply	0x00000001	Enables the Enable Default Reply feature.
EnableLogging	0x00000001	Enables event logging.

3.          Under the Error Message Instrument registry key, add one of the LogSeverity values of type REG_DWORD from the following table.

Value	Data	Description
LogSeverity	0x00000000 = EMI_SEVERITY_ALL	All message box events are logged.
LogSeverity	0x00000001 = EMI_SEVERITY_USER	Message box events with the dwStyle parameter defined are logged, including MB_USERICON, MB_ICONASTERISK, MB_ICONQUESTION, MB_ICONEXCLAMATION, and MB_ICONHAND.
LogSeverity	0x00000002 = EMI_SEVERITY_INFORMATION	Errors, warnings, questions, and information are logged. Message box events with no dwStyle parameter or dwStyle = MB_ICONUSER are not logged.
LogSeverity	0x00000003 = EMI_SEVERITY_QUESTION	Errors, warnings, and questions are logged. Information, events with no style, and user-defined severity levels are not logged.
LogSeverity	0x00000004 = EMI_SEVERITY_WARNING	Only errors and warnings are logged.
LogSeverity	0x00000005 = EMI_SEVERITY_ERROR. (EMI_SEVERITY_MAX_VALUE)	Only errors are logged.

To log message information to the event log

1.          In the HKLM\System\CurrentControlSet\Services\EventLog\Application registry key, create a new key named Error Instrument.

2.          Under the Error Instrument key, add the registry values from the following table.

Value	Type	Value
TypesSupported	REG_DWORD	0x00000007
EventMessageFile	REG_EXPAND_SZ	%SystemRoot%\System32\User32.dll

You must reboot your target system for the changes to take effect.

方法三：

Filtering Out ErrorMode Messages (Windows Embedded Standard 2009)

You can instruct the operating system to filter out certain notification messages without affecting user interface functionality.

Note:

Unlike EnableDefaultReply, ErrorMode only hides the messages, it does not intercept them and choose the default button. Be sure to check your system log to see the errors that occurred but are hidden from display.

To filter out ErrorMode messages

1.          In Target Designer, open your run-time image configuration.

2.          In the configuration editor, expand the node for the SLX file, and then expand the Windows subsystem component.

3.          In the Registry path list, right-click HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Windows\ErrorMode, and then click Properties.

4.          In the Root list, make sure HKEY_LOCAL_MACHINE is selected.

5.          Do not change the contents of the Key Name, Value Name, and Type list fields.

6.          In the Value box, type one of the following:

                            i.                To suppress system messages, type: 1

                          ii.                To suppress all messages, type: 2

7.          In the Description box, type a description for this registry value for future reference.

8.          Choose OK.
