Restricting The Viewing of Forms Per User

Please could someone assist with the following:
I'm trying to restrict the viewing of forms using bootstrap and Meteor. In other words, user A logs in and creates a simple (or 2, or 3...) form using a modal which then displays in the html on a panel. How do I ensure that when user B logs in, he only sees his particular forms and not "user A's" forms?
I haven't included any code as I haven't started working on this problem as yet.
Thank you.

That's something you need to deal with using your publications/subscriptions. See here and here for learning ressources.
Basically, what should happen is that when user A creates a form (or any object), you store it into a collection along with the user id (Meteor.userId()). You subscribe to a publication in your page where you send only the items belonging to the current user Id.
That should solve your problem, and make you ready for all the similar (and common) cases where you need to disclose selected information only, depending on the context or the user. Moreover, it means that your users will be able to find back the items they left in their previous sessions.

Hide WSS 3.0 Webpart Using JavaScript

I am using WSS 3.0 in my application. I am displaying a List as a DataView Webpart. My objective here is to make this webpart visible to a selected group of individuals. As there is no option for Target Audience in WSS 3.0, I went to edit Permissions for List and gave Read permissions only to selected users. This doesn't hide the web part from the page, rather shows an Access Denied message to other users.
Access denied. You do not have permission to perform this action or access this resource.
As I said, I want to hide this webpart, as in make it invisible on the web page from other users who do not have permissions to view it. As this message will be displayed only to those users who do not have permissions!, my approach is to search for the above message in the html and identify and hide the parentnode, thereby hiding the webpart.
I am not quite sure how to do this. Any ideas? Thanks in advance!

I'm going to assume you're in a situation where you can add additional web parts to the page and not trying to add JavaScript to the DataView Web Part directly. My suggestion won't work on a separate page if a Designer adds another view of this list.
Upload a blank .js file to your Site Assets. Add a Content Editor Web Part to your page, point it at that file. Add JQuery from a provider or host it yourself, adding the reference in your file. From there, you have 3 directions in which to work: first, explore the web part with Internet Explorer's F12 Developer Tools, keeping a particular eye on divs and tables with good unique ids, names, or classes that would solve your problem if hidden. Also keep an eye on the id of the div or table or cell or whatever that contains your access denied text. Second, (assuming you're new to JQuery) do some JQuery tutorials and then start playing with selecting the above items and, say, changing their background color. Once you have both of those, you're 90% there: (try to) select the object that would contain the access denied text, and if the innerHTML is present and equals that string, then set display:none for the div or tables to hide your web part. The third tool you have is editing the page directly with SharePoint Designer: you can toss a div with an id of your choosing around any xsl:template, which might help in your JQuery selecting.
I'm sorry I can't give you the specific code, since I'm not in a position to test it. If that changes, I'll try and give a more detailed response.
Old, misdirected answer: Do either of the answers here work for you? Alternatively, this answer has some great resources to solve your problem. Just change the message to an empty string.

Thanks Aron :D
I found the id for the webpart and hard coded it. It provided the solution, but I was hoping to programmatically fetch the id instead by searching the innerhtml, as I have more than one web parts that have to be hidden.
I found a partial solution here:
Hide SharePoint web part using javascript onclick method
I put a CEWP on the page and added the following script in it:
<script>
function hide()
{
var content = document.getElementById("webpartID").innerHTML;
var n = content.search("Access denied. You do not have permission to perform this action or access this resource");
if(n!=-1)
{ document.getElementById("webpartID").style.display="none";
}
}
_spbodyonloadfunctionnames.push("hide");
</script>
In my case, I picked up the webpart id from the aspx page or view source for the page.

split aspx page into sections rendered in tabs that load on demand

what is the easiest most efficient - from a performance standpoint - way to program an aspx that will have sections in it rendered as tabs and preferably to be loaded on demand?
I have a certain entity that can be edited by different groups of users, each user group being able to edit certain parts of it. I am thinking of rendering the parts accessible to a group in a tab on the page and then controlling access/load of the tabs based on user rights.
i know a couple of javascript frameworks that address this specific type of requirements do exist, however i am a novice js programmer, i never used it for anything more than handling control events and doing very basic stuff so i do not know how fast i can pick up and use one of them.

You don't really need tabs for that, have it a single page and just load/display data relevant to current user group.
One way to do this (since you're using ASP.NET) is to use MultiView control and display relevant View control for the current user group.

Applying Choices in Fields using View in Lotus Domino Web application

I can't quite figure out a work around for using "Use view dialog for choices" in a web based application.
My Question is how can i convert this settings in my field in the Control Tab then Choices, in choices "Use view dialog for choices" then Use current database and access view and a specific column.
Thanks in advance :)

"Use view dialog for choices" is almost always a way to get around the restrictions on the return value of a formula. For instance, you'd use it when #DbColumn in a choices formula for a listbox or dialog list choices formula would cause an error.
The upshot of that is that there's no "one-shot" workaround for the web. A direct functional replacement would be to open the view in a pop-up window or overlay div, and attach some JavaScript to the view in order to override the default web behaviour and force the return of values to a field on the main document. This approach will work well, but it may require server settings that allow the entire view to be served at once (the maximum lines to display per page will probably be less than you need), and it's subject to breakage if the HTML used to display the view ever changes.
You can use LotusScript or Java in a WebQueryOpen agent to populate a conventional widget (the list of a element) in a Rich Text field, either using PassThru HTML or a "Treat contents as HTML" form. That would involve getting the view, then doing a document-by-document (or category-by-category) run through the view index to get the column values you need. (If you take this approach, use the ColumnValues rather than the document field name to retrieve the values -- the cost of opening the document to read the values is high, and your code will take many times longer to run.)
You can also get the view as need using an AJAX request and a ?ReadViewEntries query, which will return an XML representation of the view. Again, you may have to have the maximum view lines per page limit upped in order to get the amount of data you need. You can get around that, though, by using a "suggest" method that doesn't begin retrieving data until the user enters at least one character into the field.
All of these approaches mean using a separate form for the web. That's easy enough -- you simply create a form with the same alias (or name, if you're not using aliases) as the one you're using for the Notes client. In the list of forms in Designer, you can use the hidewhen tab to hide one from the Notes client and the other from the web. (Note that you can create an additional form for mobile devices the same way if necessary.)
I can't get more specific than this with the information at hand. If this is insufficient to point you in the right direction, then edit your question to be more specific (and post a comment to this reply -- I don't spend a lot of time on SO, but I do spend time on other StackExchange sites, so I'll be notified).

Unfortunately, you have to develop it yourself.

AJAX-based name picker is a good start I guess.

What is the best approach for storing YouTube content appended to user contributed content?

So I'm trying to implement similar functionality to Facebook where I am including information from YouTube should a users post contain a link, and when clicked it embeds the video.
I've accomplished it thus far, I'm just wondering how Facebook stores this information.
To me there are two options:
1) Have the post saved as normal (it is just plain text), and if the post contains a youtube link, append it on the fly in JavaScript whenever that content is viewed. However I know that when you post a link, Facebook gives you the option to change the title, description etc. Which leads me to..
2) Generate the HTML that would be otherwise appended when viewed and store it alongside the post at the database-insert level.
If so, doesnt that add a significant amount of information per post? What happens if you want to change the formatting of all youtube content within posts on your site later on? Each will be stored individually and seems like it would be a pain.
What is the best way to manage & engineer this sort of functionality?
Cheers,

I'd store the information itself in the database, but not as HTML. Generate the HTML on the fly but store the data in a separate place. If you don't want to add too many extra database fields consider storing the information in some serialized form (like serialize() in PHP).
Anyway I would always keep information separated and never store auto-generated HTML unless it's some sort of cache that can be re-generated.

If you want the user to include his video within his text, store the link in HTML within that user's intervention, and output it as is from the database on the page. Then your users can edit their posts to decide whether to place the video before, after, in the middle or not at all, and can change the details in HTML.
If you are showing the video in some standard way, then store the video link along with the post in a separate database column, and generate the HTML on the fly. You can have data in columns for size, colour etc..., but the flexibility will always be limited to what you decide to store: if there is a database coloumn for colour then you are letting the user choose the colour, otherwise... not.
So, the most flexible is to let your users type HTML. If you think they aren't up to it, or you want to limit their choices of what they can format, you could use a java(script) rich text editor of the type that you have in stackoverflow, wikipedia etc., with possibilities to edit text in certain chosen ways via buttons. You could also store the post in XML, say in a chosen subset of HTML5 (anything that is valid in a certain container...), and transform it at presentation time.

to me this sounds like a problem that was taken too far.
if you implement ckeditor in your post form,
it should resolve the problem ( if i understood it right ),
since in ckeditor you can embed an swf/flv,
and the output will be html.
that gives the editor the power to decide exactly where he want the video ( since he can add the link wherever he wants in the form ).
since the flv/swf come with its meta data from youtube, you dont need to save that data,
just the link to the video.
