Registring the bean

- Open the form
- Add a javabean component to any block
- Register the bean (be sure that it is not in a When-New-Form-Instance trigger, or use a timer)

 



FBean.Register_Bean('BLOCK.BEAN_ITEM',1,'oracle.forms.fd.GetImageFileName');

 

 


Invoke the bean's GetFile() function


image_file_name := FBean.Invoke_char('BLOCK.BEAN_ITEM',1,'GetFile','"Dialog box title","start directory"');

 e.g.


 

 

 :BL1.File := FBean.Invoke_char('BL1.IMAGEPICKER',1,'GetFile','"Select an image file name","M:\"');
