isCOBOL Evolve : User Interface : Controls Reference : WEB-BROWSER : Styles : No-Msg-Before-Navigate
No-Msg-Before-Navigate
This style prevents the generation of the MSG-BEFORE-NAVIGATE event. This is useful when
• the web site that you’re navigating must send data thru POST (e.g. a login form) and the MSG-BEFORE-NAVIGATE event handling performed by isCOBOL causes parameters to get lost.
• the Web-Browser is used to browse disk folders, by setting the Value property to a URL that begins with “file://”.
• the Web-Browser is used to show a file with an embedded component, for example if you load a PDF file that is rendered through the Acrobat ActiveX embedded in the browser.
This style is automatically applied if iscobol.gui.webbrowser.no_msg_before_navigate (boolean) is set to true in the configuration.
