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

//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...

Cheers! Smile | :)

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?

It doesn't seem right.

Visual Studio .NET and ASP.NET question

5-Apr-02 15:48

I figured it out thanx!

My array is actually structured like this:

DivID
Caption
ID

DivID is null if no ID is available, I was forgetting to test the ID for null before trying to display the division...and ironically the first element of the array was null, so the script was failing before I had any chance of seeing output so I figured it was getElementById..

Thanx for you time! Smile | :)

I’ve build a simple test C# Web Application using beta version of Visual Studio .NET. It’s a one Web Form with text label on it using all project defaults. It works fine on my PC. But when I copied it to my web server, I’ve got following error within Web.config file:

------------------------------------------------------------------------------Parser Error Message: File or assembly name System.Web, or one of its dependencies, was not found.
Line 44: <httpHandlers>
Line 45: <add verb="*" path="*.vb" type="System.Web.HttpNotFoundHandler,System.Web" />
------------------------------------------------------------------------------

Couldn’t find System.Web.dll on a web server?
When I deleted <httpHandlers> section from Web.config file, I’ve got another error:

------------------------------------------------------------------------------Exception Details: System.MissingMethodException: Method not found: Void System.EventHandler..ctor(System.Object, UIntPtr).
Source Error:
Line 41: private static System.Collections.ArrayList __fileDependencies;
Line 42:
Line 43: public Test_aspx()
------------------------------------------------------------------------------

Looks like System.EventHandler constructor could not be found.

Any idea what is happening? Is it my fault or it’s a problem with ASP.NET setup on a web server?
I also tried to run an aspx file that doesn’t use Web forms and it works.

Any help would be greatly appreciated.

You could do this, however it would require that you load Javascript arrays into the page initially with the data you want, then loading other combo boxes with data from the arrays based on an initial selection. HTH

A number of ways this can be done. One is the store a DataSet in the application or session. You could also store the data in an XML island and mainipulate on the client side based on selections in the combobox(es). You could also create and load several comboboxes and show or hide them as required.
