示例

try
{

    throw new ApplicationException("An error has occured.");
}
catch (ApplicationException ex)
{
    string str = "The action failed. Do you want to continue?";
    ApplicationException exTop = new ApplicationException(str, ex);
    exTop.Source = this.Text;

    // Show a message box with Yes and No buttons
    ExceptionMessageBox box = new ExceptionMessageBox(exTop,
        ExceptionMessageBoxButtons.YesNo,
        ExceptionMessageBoxSymbol.Question,
        ExceptionMessageBoxDefaultButton.Button2);

    // Enable the check box.
    box.ShowCheckBox = true;

    // Define the registry key to use.
    box.CheckBoxRegistryKey =
        Microsoft.Win32.Registry.CurrentUser.CreateSubKey(
        @"Software\TestApp");
    box.CheckBoxRegistryValue = "DontShowActionFailedMessage";
    box.CheckBoxRegistryMeansDoNotShowDialog = true;
    box.DefaultDialogResult = DialogResult.Yes;

    // The message box won't be displayed if the
    // "DontShowActionFailedMessage" value of the registry key 
    // contains a non-zero value.
    if (box.Show(this) == DialogResult.No)
    {
        // Do something if the user clicks the No button.
        this.Close();
    }
}

Try
    ' Do something that could generate an exception.
    Throw New ApplicationException("An error has occured.")
Catch ex As ApplicationException
    Dim str As String = "The action failed. Do you want to continue?"
    Dim exTop As ApplicationException = New ApplicationException(str, ex)
    exTop.Source = Me.Text

    ' Show a message box with Yes and No buttons
    Dim box As ExceptionMessageBox = New ExceptionMessageBox(exTop, _
     ExceptionMessageBoxButtons.YesNo, _
     ExceptionMessageBoxSymbol.Question, _
     ExceptionMessageBoxDefaultButton.Button2)

    ' Enable the check box.
    box.ShowCheckBox = True

    ' Define the registry key to use.
    box.CheckBoxRegistryKey = _
    Microsoft.Win32.Registry.CurrentUser.CreateSubKey( _
     "Software\TestApp")
    box.CheckBoxRegistryValue = "DontShowActionFailedMessage"
    box.CheckBoxRegistryMeansDoNotShowDialog = True
    box.DefaultDialogResult = Windows.Forms.DialogResult.Yes

    ' The message box won't be displayed if the
    ' "DontShowActionFailedMessage" value of the registry key 
    ' contains a non-zero value.
    If box.Show(Me) = Windows.Forms.DialogResult.No Then
        ' Do something if the user clicks the No button.
        Me.Close()
    End If
End Try

注解

该属性用于 CheckBoxRegistryValue 初始化复选框的状态。如果指定的注册表值存在且包含非零值，则该复选框显示为已选中;否则，复选框显示为“清除”。如果CheckBoxRegistryMeansDoNotShowDialog是true，且注册表值存在且包含非零值，消息框不会显示，调用ExceptionMessageBox DefaultDialogResult时Show返回。

申请必须在拨打电话Show前打开。RegistryKey
