System.FormatException: 'Input string was not in a correct format.'

Getting this error thrown when loading a form with ShowDialog().

Seems to be a WiseJ error from ActiveLinkColor.Get and ColorTranslator.FromHtml(string htmlColor)

Is there any way to tell what is throwing it?

I can confirm there is no custom setting of LinkLabel.ActiveLinkColor anyway, it is using defaults (“Red”)

If I go through every LinkLabel on the form, and change all the ActiveLinkColor properties to ‘Red’ using the designer, the property changes from ‘Red’ to 255,0,0.

Then, it throws the error on LinkColor.Get()

Did WiseJ at some point change the way the property was read? Because the LinkLabels are all encoded by color name (WiseJ default), but using the designer it sets them to RGB.

    It doesn’t throw the exception. It’s handled. You must have the exceptions turned on in Visual Studio.

The error is not a Wisej error. It’s all in the stack trace. It’s coming from:

System.Drawing.ColorTranslator.FromHtml

Turn off the exceptions in Visual Studio and it will be fine. There are thousands of exceptions that are handled in normal operations.
