How do you come to the conclusion that the values returned by GetScrollBarInfo are not correct? If your scroll bar window has (0, 0) it might well by that xyThumbTop is 0.

First of all... be patient. Being annoying is not going to help you at all.

Second, Please don't post solutions to chat with people asking or answering. The messages are not always sorted by date, so it can be a bit difficult to follow them correctly.

third, people here are from the whole world, so the one knowing the answer to your problem might be now sleeping.
