Font dialog unhandled exception with the .NET control if the Cancel button or window X button (Close) is selected

Recommended Posts

We get an unhandled exception with the .NET control if the Cancel button or window X button (Close) is selected on the Font dialog. Follow these steps to duplicate the problem.

1. Display the .NET Chart control.

2. Right click on the chart background.

3. Choose the Font selection from the menu.

4. Click the Cancel button or the window X button (Close) on the Font dialog.

The error dialog displays with the following

Microsoft .NET Framework

Unhandled exception has occurred in a component in your application. If you click Continue, the application will ignore this error and attempt to continue.

Parameter is not value.

The Details button shows this stack trace. 

 See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.

For example:

<configuration>

  <system.windows.forms jitDebugging="true" />

</configuration>

When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.

Thank you.

Also, it seems that this unhandled exception only happens when you follow the steps you mentioned without changing the font settings. Once the settings are changed, the exception is no longer thrown. In any case, I reported this to our development team and once a fix is available it will be on the next service pack or in the form of a hotfix.
