I have a VB6 application that has an embedded browser control. In that control, we open an ASPX page that has the RapidSpellWeb assembly loaded. When I open the ASPX page within the browser control, we get this error:

Unable to get property 'rsTCIntrapidSpellWebLauncher1' of undefined or null reference

And the control does not find any of the misspelled words.

When I run the ASPX page in IE, the error does not occur and misspelled words are found.

Any ideas on what is wrong?

Sorry we don't have any experience with an issue like that. My first guess would be browser emulation, because (assuming this is not running on XP) you probably have an IE version on that machine >IE7. So let's assume you have IE11, that means by default the web browser control is going to emulate IE7.

Emulation is not exactly the same as the original browser, so my guess is that's what is causing the error.

You can control the emulation version from the registry, see https://stackoverflow.co...-control-visual-basic-6

I would try higher versions and see what happens.

-your feedback is helpful to other users, thank you!
