Pressing Cancel During License Entry Displays Exception Dialog

Is there a place to catch exceptions so this won't happen?

Thanks!

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:

<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.

RE:Pressing Cancel During License Entry Displays Exception Dialog

Hi Molenator,

The exception that's being thrown is just a standard .NET exception, so you can just handle it like you would any other. Depending on the type of app you have, different approaches will make sense. Some approaches are outlined in http://www.inishtech.com/Support/FAQs/FAQs/Developer/Handling-License-Exceptions-.aspx

Some approaches that may make sense might be to wrap the code that's calling your protected code in try/catches which divert to a "sign up now", screen etc.

Or you could have a single general wrapper method such as:

class MyWrappers
{
    static void ExplainLicensingIssues(Action action)
    {
        try 
        {
            action();
        }
        catch(NotLicensedException)
        {
            // ... Global handling

        }
    }
}

Which one could then use e.g., like this:

void OnSpecialFeatureTriggering(object source, EventArgs args)

{

MyWrappers.ExplainLicensingIssues( () => System.LicensedAction());

}
