Unless you specify the size of the select box, you can't determine it's size before it's displayed. The size will depend on the data displayed in the list, the font and size used to display the text and the text smoothing method used on the computer.

So, either you have to specify an exact size for the select box, or resize the image after the select box is displayed.

Thanks for your kindly reply. How can I modify the size of the image after the select box has been displayed? What kind event should I use to trigger the image resizing method? I tried to use the mouse key down to display the select box, and use mouse key up to get the updated select box width and resize the image to fit it. But that won't solve the problem. I really don't know what other event that I can use to solve this problem.

Thanks again.

You only need to leave the control back to the system so that it can make the redraw. Then you can check the size of the element you added.

Use:

window.setTimeout('someFunction();', 0);

to add a call to a function that will be called as soon as the elemment has been drawn. The 0 means that it should delay 0 ms, e.g. call the function as soon as possible.

ASP.Net vs. Cold Fusion

Can someone who has worked with these two technologies tell me which is better. Pros and Cons... I know that ASP.Net is a newer technology, but that is all.

Thanks..

I work with both. I've used cold fusion for years, but am relying more and more on asp these days.

Cold fusion pros: The big one is consistancy. If you are given a server that runs cold fusion, you know exactly what is on it. While it is possible to develop custom cf tags, it is more common to just use the standard set of tags. The nice part about this is that if you develop something that you want to hand out to multiple people, you can be sure it will work across the board.

Cold fusion cons: $$$ Cold fusion server is expensive. If your site is hosted, the cost is passed along to the site owners. Therefore, a cold fusion enhanced site is more expensive to maintain.

ASP pros: A hell of a lot of support. If you shake a tree, an ASP developer will most likely fall out. This means if you have a problem, finding the answer is a whole lot easier. It also means there are many custom objects out there that you can add into your projects.
Furthermore, it is cheap. The asp engine is free if you are using IIS (or even personal web server for that matter).

Cons: Too many flavors. Let's say you are trying to produce something and you find documentation on how to do it on some random site. You copy the code and stick it on your site. You try running it and it doesn't work. Why? Because the other guy has been using some custom object that he hasn't documented. Assuming you are able to figure out what it is, you might still have to pay for this package, which increases your development cost or force you to start over and find a different way to do it.

There are other pros and cons of each, but that is what I focus on at least.

I have never ever seen cold fusion code... My company is considering purchasing an application that is in cold fusion. I have done a little ASP programming. My background is mainly C++. Is it worth my while to take a cold fusion class or is the syntax easy to grasp?

Is Cold Fusion a dying technology? Would you purchase cold fusion source code?

Re: ASP.Net vs. Cold Fusion

JKroschel10-Aug-05 5:58

Cold fusion works in tags like html. Here is an example:
<cfset name="Jim">
<cfoutput>
Hello, my name is #name#

I found it easier to learn than ASP or ASP.Net, but then again, I suck at C++ and my C background is nothing to write home about. For someone who understands the concept of server-side processing, learning cold fusion should only take a weekend (at least to a degree necessary of managing a pre-built solution). Go to the bookstore and pick up a Cold Fusion basics book. You should be set.

Is it dying? Who knows. It used to have a much stronger presence than it does now. If it dies off, it is because Macromedia is charging to much for it. It isn't that it is over-priced for what it does. I whole-heartedly admit that it is a great tool. In fact if price were not a factor, I would choose to use it over ASP/ASP.Net. I just think that the majority of the world will never be able to afford to use it.

I am trying to create "scriting.filesystemobject" using javascript

Thank u all.

There could be host of reasons for this error. For example no scripting engine is installed on your machine or you do not have permissions to access the filesystemobject, or you do not have permissions to open the necessary files.

Are you doing this as a part of your web page? also what os are you using. a lot depends on this too.

Hi Chetan,

Hello! there is a better way to do this. If you are using ASP.Net and want to create the files on the server then why are you using JavaScript? you could use C# code behind for a much richer functionality. However that is your choice.

The problem you are facing is due to permissions. Your JavaScript is not getting permission to write the file, which is what it is designed to do by default. You will have to change the web conf file for your project to grant permission to access the disk resource. Only then can you write to a file.

Thank u very much for ur reply,

The way u suggested that to use code behind to create file on server is very right but in my application it is mandatory to create it by javascript.

and u said that there could be a problem reagrding permissions, thats right.
I also tried for that but could not get proper solution. actually It was performing in fine way just berofre two days.
but now it not working.

Thank u again for ur suggestion and the way u suggested.

Cancelling the META REFRESH timer

<meta http-equiv="refresh" content="10; url="http://www.lama.com/">

That code will refresh the browser to the indicated URL 10 seconds after loading the page.

How can I cancel the refresh timer? I have tried removing the meta tag element but that does not work.

How did you remove the tag? Using javascript? Once the page is loaded it's probably to late to stop it.

Are you using any server code? Then remove the tag on the server side, e.g. don't write it to the page.

By other means (window.location= / window.location.href=), redirect to another page less than 10 sec after the page loads.

Pardon? I don't want the page to redirect at all, the meta refresh needs to be cancelled all together. I cannot strip out the meta refresh before it gets to the browser either.

I am experiencing problems with events.

I want to develop (eventually) a keyboard pop-up window as a user control that will pass data back to the page.

I have attached a cut-down version and now basically all I have is a web form with a textbox, and a user control with a button on, which when pressed will populate the textbox with some characters.

I’m trying to use events to do this but I get errors, can any one help?
