File restrictions

html or javascript question

7-Apr-02 7:22

When I ftp files to a server anybody could download them right...?

I would have to chmod the file thingies in order to prevent unwanted downloads...?

I couldn't do this with a JScript file though because then the browser wouldn't be able to render the document properly correct...?

When would I use file restrictions...? On a database which I wanted no one to have access to...?

You would write a intermeditae script to access the info in the database instead...?

Thanx!

A JScript file is downloaded by the browser, so you need to set permissions on that, the same as the permissions on your HTML pages.

Since a database is only accessed from the server (from the PHP pages or something) then you only need to allow access to it from the server, not from the outside world.

Generally speaking, any file you dont want to allow someone to download, dont put it in an accessable directory. Since for a database that is accessed from PHP, it really doesnt matter where the files are (it has access to the file system of the machine)

My problem is this:

I have a webform with a lot web controls(inputs,ckeckboxes etc).

When I submit the form to I want to be made some client operations before sending to server: i want to modify a hidden input or the value of a input control in some way.

How do I make this? It is posible to add an onsubmit() event handler to webform although it is a form which have runat="server" and make all what i need in hat handler?

thanks.

I'll look when I'll come home (if someone won't do it before). But what for you need it? It won't hide the source from someone who want to steal your picture.

Here are several scripts that do the work:

http://javascript.internet.com/page-details/no-right-click.html
http://javascript.internet.com/page-details/right-click-menu.html

(all links will be opened in a new window)

Remember though, there is NO 100% solution for this problem. If someone want to see a source code, steal an image, he always can do it, you cannot protect it on client side Smile | :)

A rant about ASP.NET controls

Chris Maunder6-Apr-02 23:17

One thing that often frustrates me about Word is the brain-dead way it creates HTML from a word doc. Instead of a simple set of <p>'s, it creates <p align="left">, or <p class="MSOMonstrosity"> or, more often <span areallyhugelonglistofclassattributes>. Clean out all this crap and it displays exactly the same.

So - I'm now moving pages that have been handcoded with complicated stuff like:

<table cellSpacing=0 cellPadding=1 border=0 width="100%">

to be more ASP.NET friendly, so it becomes:

<asp:Table BorderWidth=0 CellPadding=1 CellSpacing=0 Width="100%">

Personally I love the new format. What really drives me nuts is when the output is straight out of the Word Bible of rendering HTML:

<TABLE id=SearchNavBar_tblSiteToolbar
style="BORDER-TOP-WIDTH: 0px; BORDER-LEFT-WIDTH: 0px; BORDER-BOTTOM-WIDTH: 0px; WIDTH: 100%; BORDER-COLLAPSE: collapse; BORDER-RIGHT-WIDTH: 0px"
cellSpacing=0 cellPadding=1 border=0>

I've been looking through some of the pages I use - many of which are table intensive, and pages (which are already fairly large) are now threatening to become 50% bigger simply because the HTML renderer for the WebControls isn't smart enough to leave out superfluous styles.

Please someone tell me I'm missing something obvious here and that there is a way to keep WebControls lean and mean.

cheers,

This would mean that Code Project .NET would be faster than the current site at the server side, but at the client side it will be slower cause the HTML is now bulkier Frown | :(

That's what I have to ensure doesn't happen (the slowness, not the speed).

Initial runs show the ASP.NET pages run about 5X faster than my old ASP pages. w00t!

When I use the CssClass attribute, the style tag goes away (when using grid positioning it appears again, for obvious reasons). But this can lead to problems with older browsers (if you care).
Other solutions could be:
1. Using the LiteralControl (I know, I know, this defeats some of ASP.NET's strenghts; but for sheer performance, this can be useful in some VERY large pages).
2. Deriving your own Table .NET server control, that renders minimal attributes (only those you need). It's pretty easy.

Possibly the LiteralControl will be the way I'll go, though deriving a new Table control and ensuring it behaves may be a wiser solution.

And while I'm at it I guess I can make it actually cross browser compatible (for things like thin borders and such), as opposed to the current implementation that just throws it's hands up in puzzlement.

Hmm - I see a new article in the making Wink | ;)

Thanks Daniel!

Need help using Visual Studio.Net!

Chris,
There really is no way to keep WebControls lean and mean, but IE does an outstanding job of rendering the gargantuan amount of HTML that ASP.Net spits out. Especially IE6! Gee, I wonder why that is? Could Microsoft have optimized IE6 to play well with .net? Poke tongue | ;-P

Anyway, if you just insist that everyone use IE, then we won't really have a problem loading the aspx pages!(Sorry Nish, I know you have to use UNIX.)

In fact, I ran tests with the ACT(Application Center Test). When I handcode database access to SQL Server(Dimming a SQLDataAdapter, etc...) my page runs slower than when I drag a SQLDataAdapter onto the page and go through the wizards, even though the latter generates so much more code in the codebehind file than the other.

Hi guys,

I need help using Visual Studio :P I have 2 questions i guess most newbies have on their minds Smile | :)

Q1)
This error is kinda annoying. I need to change Codebehind to src and change the contents of inherits in the solution explorer to make the code behind work. For example:

Page Language="vb" AutoEventWireup="false" Codebehind="databaseconnect.aspx.vb" Inherits="localhost.databaseconnect"

to

Page Language="vb" AutoEventWireup="false" src="databaseconnect.aspx.vb" Inherits="databaseconnect"

But when i do these changes in visual studio.net i can't go to design mode anymore--i need to change it back and forth to go to design mode. Any explaination?

Q2)
In "class view" mode, Len Mid and Random functions dont work. Visual Studio.net does recognize those functions but when u compile it, it errors.

It gives me this error:
Compiler Error Message: BC30451: Name 'Mid' is not declared.

Thanks,
Bobby

Timer question

alex.barylski5-Apr-02 18:39

5-Apr-02 18:39

//Screen mouse coordinates 
var x = window.event.x; 
var y = window.event.y;

//Get the element at the current position
var obj = document.elementFromPoint(x, y)
/* Determine if menu popups should be shown or hidden */

//Mouse has left the popup menu, lets hide menu
if(obj.id == "Popup"){
  status = "Keep showing POPUP";
}
else{
  status = "Timer for hding POPUP";
  setTimeout("menuControl.HideAll();", 2000);
}

the following is mapped to the onmousemove event

HideAll() hideas all the divisions

This doesn't make sense...when the mouse is over the specially labeled popups with div id's 'Popup' the timer is supposed to stop, but when the mouse is over something that isn't like the document.body or another element that isn't id'ed Popup...the timer should kick in and call HideAll() to remove the specially labeled Popup's from display

What actually happens is the popup will show...but only for a split second(shorter and shorter it seems) and then disappear???

The code is a for a drop down menu, if that helps...

Any ideas...?

Thanx again! Smile | :)

I figured out another solution...thanx anyways!

I finally completed my cool drop down menu...I can finally proceed with my friggen site. Smile | :)

I'll actually maybe score clients...up til now i've onoly had a few...and only because they knew I was competant...with my own site up...

Sweet!!!

Anyways...my menu has some short falls, here they are:

IE 4+ ONLY, but soon will support NS if client base requests it.

No sub-items on the popup menus.

I did however implement it in such a way that it'll make it way easier for newbies(friends I often get to help out) to deign an a website with drop down menus...

What are your opinions about the short falls...?

Are the sub-items really nessecary...?

They way I designed it would make it quite hard to add that feature.

Otherwise it's totally customizable...I love it...i'm so proud of myself...2 days...and i developed a drop menu...all JSCript...I don't even enjoy programming in JScript...C++ is so much better and more flexible and compilers make all the difference in the world.

I got stuck for 3 hours on my menu because I was missing a single quote...it kept crashing...try catching that in notepad...

I later used VC++ editor, but syntax hilites only make a small difference.

Speaking of which...does any one know of any good editors out there for JScript only...that interpret code and catch errors like missing single quotes...?

I've tried the MS Script debugger, but didn't like it at all.

I'm going to download something a friend suggested called FSA Script debugger...? I think anways...

Any ideas...?

Cheers! Smile | :)

getElementById trick question.

6-Apr-02 2:38

Perhaps...but you must remember, this is competition territory...any good ideas I have...I don't much feel like having robbed from me by some BBD(Bigger better deal) company.

I don't mind sharing, but unless I feel I have something to offer the programmer community it's senseless to link back to my site...where ideas could potentially get stolen and made bigger and better by a larger biz.

i'm thinking of selling software online through my site...if I did that I would no dought post a link to my website, but until then...I really can't get over the fact that some promotional idea's I use to get clients would be stolen and used...

Re: getElementById trick question.

5-Apr-02 14:40

I'm sure it's not really a trick question, but i've only prorgammed in Jscript for a couple months, so i'm still a little shaky.

In trying to keep with xhtml standards...attributes and such are all enclosed in quotes

Hello

Now it's usually easy to move the divsion about the screen

document.getElementById("ThisIsMyID").style.pixelLeft = 100;

(I think i've done that right, thats not the problem i'm having)

What i'd like to know...assuming I have 20 element ID's stored in array and I wanted to make all but the 5th element invisible I might do something like:

for(i=0; i < 20; i++){
  if(i != 5){
    document.getElementById(myArray[i].DivID).style.visibility = "hidden";
  }
}

I'm thinking because the id was encapsulated in quotes and the ID's in the array are not...getElementById is failing for this reason...?

When I directly call getElementById("ThisIsMyID") everything works fine and when I try and use the ID stores in the array it fails...what gives...?

I've tried wrapping the ID in quotes like this:

var temp = "\""+myArray[i].DivID+"\"";

and passing this to the getElemenById function but still no luck.

I have also generated HTML on the fly and used the following

menuCode += "<td class='MenuItem' ShowPopup('"+barRef[i].DivID+"', this); \" >"+barRef[i].Caption+"</td>";

the above worked fine, why won't iterating the array work..?

Any ideas...?

Thanx! Smile | :)

do an alert( myArray[i].DivID );
are you getting a read ID from that?
