>>Correct - by using a General field , you've given up direct access to the field content, relying instead on the services provided by the application handling the general field for VFP. If you want to access the content without relying on the server, you'd need to store the binary bitmap data in a memo field and extract it to a file for the API call to reference.

>100% accurate. But what if I want to ask the server to print the content of the general field instead of displaying it on the screen? The server application (paintbrush) certainly can do it, but how can I use this service? I thought that I can relly on the Object property of OleBound control, but the Object property is actually NULL...

You'd have to tell the General field's server to use an available Print function through its implied call to ShellExecute(). Since there's no way I'm aware of to link to the General field through the API, you're stuck with using internal tools in VFP that know how to do this. If the data could be extracted from the General field, then the server's verb could be invoked through ShellExecute()/ShellExecuteEx(), but you've precluded this as a solution by using a General field.

IOW, you can't get there from here.
