Dear Sir./Madam.,

I play with the HelpNotes sample. I replace the .rtf with some of my own. Sometimes I found out that the first line in the .rtf is divided into two lines when being displayed. But I don’t want this. Do you know why this would happen? How to correct it?

Thanks!

We have used a technique called bottomless rich edit control to implement measurement of RTF tooltip windows. Here are the resources relating to this technique:

We implemented our own RTF measurement based on the EN_REQUESTRESIZE notifications. You may want to implement your own instead.
