Question

I tried using SendKeys.Send("{TAB}");

to tab to the next control on my form.

I get error message,

"SendKeys cannot run inside this application because the application is not handling Windows messages. Either change the application to handle messages, or use the SendKeys.SendWait method."

How do I change the application to handle windows messages?

Regards Tony

Hi,

Thanks for your post.

Use Form.ShowDialog method instead of Form.Show method. This may solve it.

Sincerely,

Hello,

I know it's related to your first thread 'focus on a textbox' you may want to try my solution.

p.s. SendKeys is not reliable, it seems like a hack and I'd avoid it if possible.

Eyal, Regards.
