Hi,
I'm using a combination of SendKeys and SendMessage to send data to a third party form. (I hope to convert it to all API calls once I solve some other issues, such as finding the handle of an App's "Find" window.)
Both try to send the next data to the App before it has finished processing the previous data. I've added infernal "do nothing" loops between the sends. I have already had to adjust the delay from .5 to .75 seconds.
However, while the App is processing the data, the mouse cursor is an hourglass when placed over the form.

Question: Can I use this somehow to tell when the App/Form is ready for the next data stream?

Thanks,
Al.
