[SOLVED] - grub2 hide/unhide

A mate has two win98 and one win95 on his first hard disk and a second hd for - ubuntu. To get M$ to see the correct C disk, grub legacy stanzas for any one of the win9x have always had to include two hide and one unhide command.
Ubuntu comes with grub2 and I thought I'd try super grub disk first and see whether I can boot all win9x - but no. SGD sees them but does not hide/unhide the relevant partitions so that it always boots the first win9x.
A bit of googling found parttool as part of grub2 command line possibilities which has a hidden+/- feature.
I won't be able to try this on his computer until this pm:
1) boot from SGD
2) go into CLI
3) use parttool to hide/unhide the relevant partitions (say hd0,2)
4) set root (hd0,2)
5) chainload +1
6) boot
And I should be good to go. Am I on the right track? Any advice of course welcome
PS.:
This is more of an exploratory/note taking thread with a view to a proper wiki entry if I succeed as there is nothing on google or the web out there that applies to grub2 CLI stuff.

Okay, this is solved, parttool did the trick on the grub CLI.
The following sequence hides the first two C disks and boots off the third - something super grub disk was not able to do automagically
parttool hd0,1 hidden+ boot-
parttool hd0,2 hidden+ boot-
parttool hd0,3 hidden- boot+
set root=hd0,3
chainloader +1
boot

How to Dynamically Hide-Unhide Report Details

Is there a technique to hide/unhide data?
I am creating a report that summarizes transaction data. The users want the opportunity to review the details behind the summary as the report is being reviewed.
Is there a way to hide the detail data while providing a mechanism for the reviewer to view the detail as desired?
TIA

I have implemented this in BI Publisher enterprise and using the desktop version and I don't get this error..
I did come across another thread that discusses this error. R12: Namespace prefix 'dhtml' used but not declared.
Not sure if that addresses your setup and issue.. You can send me your template to [email protected] if you would like me to take a look.
Thanks!

How to Hide / Unhide iGrid Applet

I'm attempting to develop an irpt page which will feature two grids / applets. The topmost grid will be visible upon initial load of the page. Upon selecting a record from the top grid, I'd like to then unhide the bottom grid so that a user may select a row from it before then calling another page.
I've tried all of the following methods to hide / unhide the grid but none appear to be working:
1) Set the style.display of the applet to 'none' and then set it to 'inline' after row selection of the top grid.
2) Set the column widths of the bottom iGrid to 0 and then use the document.iGrid-applet.ColumnWidths=x,y JS command after row selection of the top grid.
3) Set the initial width of the iGrid applet to 1 X 1 and then use the document.getElementById("applet-iGrid").style.width / height = 'xxxpx' after row selection of the top grid.
None of these solutions work. It appears that once the iGrid applet is loaded, none of these properties may then be utilized to change it's appearance.
How can hide upon load and then subsequently unhide an iGrid applet??
Thanks in advance,
Randy

Thanks Udayan - this worked.
Only other tidbit was that it appears you first have to set the style display to inline in the div tag (to ensure all subsequent object references to the grid are valid).
Then in the function called by the update event of your top iGrid applet, you have to hide the bottom iGrid/applet with the style="display:none" command.
Then in the function called by the selection event of your top iGrid applet, you have to unhide the bottom iGrid/applet with the style="display:inline" command.
This ensures the applet is first displayed (so that all references to the grid object are valid), hide it when the first (top) grid is displayed, and then unhide it when a row is selected from the first (top) grid.
Thanks again,
Randy

Hide/Unhide Button on a Custom Form?

Hello! I am looking for some ideas regarding the ability to hide/unhide a button on a custom form. Ideally, I would like to create an authorization group, if a user is a member of the authorization group, they can see the button, if not, the button is hidden. Is this something that can be done? If not, does anyone have another way of doing this? Thank you.

Are you asking specifically for Smartforms, SAPforms, Interactive Adobe forms? Or generally about UI programming?
Generally yes, this is possible and is also often done to give the user a more friendly interface to work with (without having to click on buttons, only to discover that they cannot use it anyway).
Many standard transactions are developed in this way.
Cheers,
Julius

Hide/Unhide Email Account

I think there are many times in one's life where it would be great to be able to hide/unhide an email account (without actually deleting it). For instance, when one is on vacation and doesn't want to be "in touch" with what is going on at work via your mobile device which we often use for both work and personal purposes. It would be great if this feature were available with the next iPhone OS update. I think many people would find it of benefit. Hopefully this will get done!

?? You can already do this. In settings, just go into the settings for a particular email account, and turn it off. When you launch the mail app and it updates, any account turned "off" will not show up. To get it back, just go back into it's settings and turn the account back "on" (it's just a slider switch).
Unless I am completely misunderstanding what you want.

Hide/Unhide photo shortcut?

Is there a Hide/Unhide photo keyboard shorcut? There is none listed on the shortcut list.
Having a shortcut would seem critical for a good workflow: View your Album/Event full screen and just press next and (if necessary) hide the photo...
I guess the other alternative would be to add it myself using Keyboard Shortcuts under Keyboard and Mouse in the System preferences.
[Edit] Nevermind - just found it - Command L [/Edit]

Hi Hannes,
Use the menu Edit >> Keyboard Shortcuts to modify/create new shortcut keys for the menu commands in AI.
Just select the option "Menu Commands" in the drop-down list and modify/create them accordingly.

Page hide Unhide in acrobat

Is it possible to hide/unhide page in acrobat? How can I do?
Can it work in reader?
Please help me....

As it has been said, Acrobat can do it rather easily.
For Reader, there are some possibilities.
• You have access to the Reader Extensions Server (or whatever they call it today), and then you can spawn Template pages, and delete them again in Reader.
• You work with "virtual pages", by making the pages the icons of page-sized Button fields, and provide according navigation tools. Showing/hiding fields works in Reader without the need of any additionsl rights. It may, however, be a little bit unusual for the users.
HTH.

Hide/Unhide Columns in WEBI Report output

We have a WEBI report which has 2 columns/measures to display the cost in EUR and USD. User would like to have the flexibility to filter the column so as to display USD or EUR cost column. Is it possible to hide/unhide column in WEBI. Can we have a input control on multiple measures so that user can dynamically select which measures they want to see on report.
Its possible in BEx Analyser using filter option on key figure. Is simillar functionality available in WEBI? We're on BO 3.1 XI. Is thre any other way to achieve this?
Thanks,
Milind

hi,
i think it is not possible to hide a column based on condition. but in webi 4.0 u have an option using which, u can hide/ show a table based on the user selection. in ur scenario, create two tables, one with value in USD and other in EU, super impose the table. then right onthe table and select "Format cell". in that u ll have a option to hide the table based on condition. select that and apply the condition.
see the follwoing url for more info : http://bihappyblog.com/2011/11/05/dynamic-visibility-in-webi/
thank u,

JavaScript - How to collapse/uncollapse (hide/unhide) the top menus in SharePoint 2010?

Hi there,
I will appreciate if someone can provide JavaScript that can hie/unhide the top ribbon and navigation menu? (SharePoint 2010)
Thanks.

Hi,
By investigating the page source, we can see that the Ribbon is corresponding to the <div> whose id is “s4-ribbonrow”, the Top Navigation is “zz17_TopNavigationMenuV4”,
then we can change the style these two elements to hide/unhide them.

Could you please help me how to do above one.
Badri

Hi,
According to your post, my understanding is that you want to hide/show the TreeView when the Checkbox checked/unchecked.
We can use jQuery to achieve it, the following script for your reference:
<script src="http://code.jquery.com/jquery-1.10.2.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("input[type=checkbox]").click(function () {
if (this.checked) {
$("#TreeViewID").hide();
} else {
$("#TreeViewID").show();
</script>
