Just for future reference, regardless if you are posting in the Forms area of the forum or any other, terms like Forms 11g, Oracle 11g, etc are parts of product names. They are not version numbers although they do offer a slight hint. It is very important that when posting you include the complete version number of any products related to the problem or question you have. For example, you said you are using Oracle Forms 11g. Look at how many possible versions "Forms 11g" could possibly be:
11.1.1.1
11.1.1.2
11.1.1.3
11.1.1.4
11.1.1.6
11.1.2.0
11.1.2.1
With each new patch release and major release, a large number of bug fixes are included. In the case of new major releases, in addition to bug fixes, many new features are added. So knowing the version number is important.
Beyond that, it would appear that you have many questions:
1. How to copy and paste
2. How to execute a system shutdown
3. How to force the browser into full screen mode
4. Refresh - this one is unclear. What do you mean by "refresh"?
Let me answer those that I can:
<blockquote>o Functions like cut/copy/paste are available directly from your Forms code. For these I would recommend referring to the Builder's Online Help. Look for CUT_REGION, COPY_REGION, PASTE_REGION. It might also be helpful to understand SELECT_ALL. For example you may want to code a Copy button like this:
GO_ITEM('some_text_field);
SELECT_ALL;
COPY_REGION;o To execute a system shutdown on the client machine, you would first need to WebUtil enable your form. Refer to the Forms Builder Online Help for information about how to use WebUtil. You can also find lots of information in this forum about WebUtil. Once enabled, you can execute a Windows shutdown in various ways. Here one option:
Declare
     my_cmd varchar2(255);
Begin
     my_cmd := 'cmd /c start "" "' || '"shutdown -s -f -t 1"' || '"';
     WEBUTIL_HOST.HOST (my_cmd);
End;Refer to the Microsoft documentation for more information: http://technet.microsoft.com/en-us/library/bb491003.aspx
o I'm not sure what you are attempting to do with the F11. I understand that this function key sets the browser to full screen, but the form will not exactly adjust for this change in browser size. You can adjust the applet size dynamically, but not the form. For that you would need to code the behavior yourself. So, before I can offer something specific, it would be helpful to understand what you expectation is and if what you want is to set the browser to full screen, why not just allow the end user to do it? You could easily have a java script popup displayed before the form starts which might say something like "To maximize your browser, press F11"
o Finally, "refresh". I don't know what you mean here. Refresh what? The Windows desktop, browser, Oracle Forms.....
