Use count(*) instead of count(1). The first one will not check if the argument is null, while the second one will evalue the argument once for each record in the table (unless the optimizer is smart enough to recognise that the expression is constant). If the table is using the MyISAM storage engine, you should get a response quite a lot faster than 40 ms, as that engine keeps track of the number of records in each table.

Hello Friends,
Is there any way to find the users action in print dialog box. That is , if we are using a window.print() command in _javascript then it opens print dialog box. It shows us printer setup in that and also it contain print and cancel button. Now i want to know whether user clicks print button or cancel button. If u have any idea about this pls tell me.

No.
Why is it so very common that people don't write what they really want to do. What is it that you really want to do? Find out if the page was printed or not? That is only possible by asking the user, and still the user can lie to you...

Howy folks,
Its been long since I've looked into HTML, and recently while developing a HTA application, I needed to come up with a UI that looks like a standard dialog with HTML elements (e.g. button, text field) that automatically resize themselves when you resize the main dialog window.
If you take a look at: http://www.codeproject.com/dialog/resizabledialog.asp, you'll know exactly what I mean.
For folks acquainted with the .NET framework, there's a property called ANCHOR, which achieves similar effect for UI elements.
Thanks in advance.

Greetings all.
For various reasons I'm having to use an IFrame to integrate content into somebody elses CMS system and thusly design/code.
This is causing me problems, because I can not get the IFrame to expand dynamically with the content it loads.
This either gives double scrollbars or much extra unneeded spaces.
My IFrame is located within a relative positioned DIV which has position relative on it.
The IFrame then loads my page(s) and displays them.
But I just can't get the IFrame to expand..... *grrr*
Please help me before I go postal on the client

Sorry if i sound like an idiot - it's been years since I worked with an iFrame.
As i recall the width and height were passed on the creation of the iFrame.
Do you want the iFrame to:
1) Determine the size of the container that is holding it.
2) Use the size discovered in step 1 to resize itself to expand to fill it's container.

I want the IFrame to expand with the content it shows, that is the page which I pass as the source. That size I can't know, which is why I wondered if there was any possiblity of making the IFrame "relative" in size.

I am working on a webshpere application coded in javascript, java and html.
My problem is that sometimes, when I am opening an error popup (it is just an alert)
I can't see the image. I have a cross instead like if it could not find it.
The thing is that it does not occur everytime, almost never.
I tried to reproduce this by emptying the IE cache and the jsp one... with no success.
Any hint would help

What im trying to do is write an Internet Explorer sidebar using BandObjects (as described by Pavel Zolnikov at http://www.codeproject.com/csharp/dotnetbandobjects.asp).
In my explorer window am simply displaying a webbrower object which is displaying some webpage.
What I would like to be able to do is be able to gain access to the page being being displayed in the actual browser window (ie not the sidebar browser) and be able to access it using Javascript in my browser being displayed in the sidebar.
Does anyone have any idea on how to do this?
Thanks
Imran

I want to run a click event on load, is there a way to force a click event. I believe this would be easier than double writing script. I can see the function if I use alert(document.getElementById('?').onclick) but I can't figure out how to have it run.
|
|
|
|
|
Call the click() method of the element.
---
b { font-weight: normal; }
|
|
|
|
|
How'd I not remember that...
Final code:
document.getElementById('?').onclick()
|
|
|
|
|
document.getElementById('?').click();
---
b { font-weight: normal; }
