(JVCL - JEDI) Is it possible to change the caption on JvLoginDialog1 that says "type your user name and password to enter the application" ?
I presume you're talking about the "hint label", instead of the Caption which you can change in OI. You can modify/localize RsHintLabel resource string in 'jvresources.pas' for that. Also see other entries under the heading 'JvLoginForm.pas' in the same unit.
