working on a client's website that has a gallery and uses a thumbnail.aspx page to shrink images on their site for product galleries. However, they want to move the image files to another URL so I need to modify the thumbnail.aspx code to use a networkstream, but I'm not sure exactly how to do this. Could someone point me in the right direction?

View 8 RepliesI have an image control that puts user's photo in it. Once it's loaded, I resize it using the javascript.But the thing is, when the page is loading, the image gets really big, then shrinks down being called by the javascript. Is there a way for me to pre-load the image before displaying it? I do'nt want to set the image control's width and height to fixed pixels at this point.
View 8 RepliesSo I created a site optimized to be rendered in a mobile device. I set the Width Site is looking good on Blackberry of my <DIV> tags to be about 300px, for the most part, to account for the reduced screen size. However, the IPhone Safari browser renders this to the screen extremely small, and I can only assume that it's automatically reducing the size of the html accordingly to fit the device. Again, Blackberry does not do this.

Is it possible to create a popup window using an Aspx page and Java Script? I thought I saw this done once, but I don't recall how it was done. Here is really what I want to accomplish
So here is the pseudo code of what I would like to do.
1. Have an Aspx web page named default.aspx with a button on the web page named "Press Me"
2. Have an Aspx web page named popup.aspx that is 1/4 the size of the web page in step 1 and has a texbox control named txtPersonsName. And a submit button.
3. When the button on default.aspx is pressed, the web form in step 2 popup.aspx is displayed giving the impression of a popup window. A person enters their name on popup.aspx and then presses the submit button. The popup closes and the code behind of default.aspx captures the name entered in popup.aspx
Thougths: I think popup.aspx can be displayed using Java Script from the code behind of default.aspx. Or from within default.aspx.
I need to be able to write something like this into a textarea "Hello user, Welcome to a random place. but then when I grab the text for use, I want to grab the HTML so it would be
"Hello user,<br/>Welcome to a random place. We hope you enjoy your stay! </br></br>From the team."
I dont really want to go the trouble of getting a 3rd party component with all the bells and whistles because my requirment is simple, and the emails will have no formatting. (apart from the line breaks)
I also do not want to use an server control because this part of my site is strictly JQuery AJAX and only uses static code behind methods for the AJAX calls.

View 4 RepliesI need to include an offsite javascript file on my page, however I don't want it to be able to affect the performance of my site, in case the server where the javascript is on is down or not responding.
What I'd like to know, is if it's posible with javascript to make some sort of wrapper function to ensure that the page where the offsite javascript is hosted is responding within an acceptable timeframe.
I've considered adding the "defer" attribute to where I include the javascript, but that would as far as I know still leave the site hanging after the rest of the page is loaded.
If it's not possible to do in javascript are there any good alternatives?
My site is made C# asp.net.
