Ah! Thanks for that. so it is probably to do with cookies eh!
I'm studying ASP.NET 3.5 and I guess this sort of thing is more web design stuff than development?
Do you reckon studying ASP.NET technology is the way to go if you want to learn about how this sort of thing works? or is it more the preserve of web designers?
The trouble with learning Microsoft stuff and passing the MCP's is it doesn't teach you the creative flair! and seems mostly concerned with business apps!

I need help with this javascript - ajax code and I'm new to both js and ajax. I have this code that the onClick function is not working. I'm not receiving any errors. I'm expecting the code to return the value for var str within the function getForm(fobj) to to equate to " name = value" when the onclick function executes. Instead I'm getting empty string. Thanks for your help.
<script>
var req = createXMLHttpRequest();
function createXMLHttpRequest() {
var ua;
if(window.XMLHttpRequest) {
try {
ua = new XMLHttpRequest();
} catch(e) {
ua = false;
}
} else if(window.ActiveXObject) {
try {
ua = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
ua = false;
}
}
return ua;
}
function sendRequest(frm, file) {
var rnd982g = Math.random();
var str = "";
if(str = getForm(frm)) {
req.open(
req.onreadystatechange = handleResponse;
req.send(null);
}
return false;
}
function handleResponse() {
if(req.readyState == 4){
var response = req.responseText;
document.getElementById("results").innerHTML = response;
}
}
function getForm(fobj) {
var str = "";
var ft = "";
var fv = "";
var fn = "";
var els = "";
for(var i = 0;i < fobj.elements.length;i++) {
els = fobj.elements[i];
ft = els.title;
fv = els.value;
fn = els.name;
switch(els.type) {
case "image":
str += fn + "=" + encodeURI(fv) + "&";
alert ("string is" + str);
break;
} // switch
} // for
str = str.substr(0,(str.length - 1));
alert ("string -1 is: " + str );
return str;
}

Dear all,

Somebody deletes all source code from server. I cound not find any information of them either in IIS log or FTP log.
Any body can help me please how I can detect who is doing this hell.

Do not cross-post. You've already got this posted in the ASP.Net forum.

I apologize if this is a repost but I searched for something similar and came up with nothing. I have a couple of questions I'd like to ask some of the more informed web gurus out there. I have Adobe Dreamweaver, Microsoft Expressions Web, Microsoft Expressions Blend, Visual Studio 2008, 2010. I'm not savvy when it comes to web development but I am looking to better myself in this field over the summer. Out of the above mentioned web dev IDE's what (or what combination) would be the best to learn?
|
|
|
|
|
If you are looking to develop web applications that need to interface with a database, I would start with VS 2008.
|
|
|
|
|
I all depends on what you want to do. If you have VS2010 then VS2008 isn't necessary at all. IMO Dreamweaver is more for designers, if you really want to dig in to web development then use VS. Of course Dreamweaver also doesn't do ASP.NET, so if you want to learn that, then there is no choice, only VS. Expression will help with good graphics and layout support and integrates with VS. So my recommendation would be VS2010 and Expression.

Hi,
I want to take MCTS certification on .Net Framework 3.5. for this which exams i need to take?
i think first i should take 70-528 after that 70-562. am i right? i didn't done any certification previously and this is first one. Again 70-536(.Net framework 2.0) is mandatory to take before this?
please suggest me how to take this exam?

70-536 (Application Development Foundation) is first.
After that just do 70-562 (for ASP.Net 3.5) you don't need the 2.0 one first.
Microsoft Learning[^] lists the various tracks.
Good luck with the exams.

I recently looked at websites selling clothing.
Today when I logged on to my Orange webmail, the ads on the page miraculously displayed links to the sites I'd visited.
As a web developer, I'm intriqued to know how this is done.
|
|
|
|

Lots of large sites (including code project) use Ad networks like doubleclick.net to handle ads. That banner at the top is actually delivered from a doubleclick.net server. Because it is delivered from their server, they can set a cookie for their domain on your machine. They also know which site you were on when the ad was delivered based on the URL. http://ad.doubleclick.net/adi/N5072.CodeProject/B4526008;sz=728x90;ord=634098885627770045?
The next time you go to a site with a doubleclick ad they can look you up based on your cookie, see what other doubleclick sites you have visited and deliver appropriate ads. If you use an Anti-Virus scanner one category of "threat" is a "tracking cookie". If you delete all of those you won't get targeted ads (until you visit enough sites again).

I have a client-based application in which I am trying to display and use data that is stored on the client's computer in an INI file.
I have been reading on this and still have not the javascript snytax to do this.
The INI will exist on the client's system. In order to find it requires reading the client system variables to get the path for the file.
Having diffculty with the best syntax to accomplish this.
Thank you.

I have this code snippet from Weather.com that displays local weather.
In the script portion of code is the var wx_locID which is the zip code of the hosted site.
I am trying to enhance this functionality by allowing the client to enter their own zip code, have it saved, then retreived using a cookie, then pass the value to the var in the script when the client clicks on the weather icon.
I am having difficulty passing the value to the var.
Any perspective would be appreciated.
Here is the script:
<div id="wx_module_7847" style="padding-left: 225px;" >
<a href="http://www.weather.com/weather/local/34979">Your City's Weather Forecast, AA (11111)</a>
</div>
<script type="text/javascript">
/* Locations can be edited manually by updating 'wx_locID' below. Please also update */
/* the location name and link in the above div (wx_module) to reflect any changes made. */
var wx_locID = '08043';
/* If you are editing locations manually and are adding multiple modules to one page, each */
/* module must have a unique div id. Please append a unique # to the div above, as well */
/* as the one referenced just below. If you use the builder to create individual modules */
/* you will not need to edit these parameters. */
var wx_targetDiv = 'wx_module_7847';
/* Please do not change the configuration value [wx_config] manually - your module */
/* will no longer function if you do. If at any time you wish to modify this */
/* configuration please use the graphical configuration tool found at */
/* https://registration.weather.com/ursa/wow/step2 */
var wx_config = 'SZ=300x250*WX=FHW*LNK=SSNL*UNT=F*BGI=spring*MAP=null|null*DN=askbillbradley.com*TIER=0*PID=1177763389*MD5=be2899d91f6feddef8216cd03ec459a7';
document.write('<scr' + 'ipt src="' + document.location.protocol + '//wow.weather.com/weather/wow/module/' + wx_locID + '?config=' + wx_config + '&proto=' + document.location.protocol + '&target=' + wx_targetDiv + '"></scr' + 'ipt>');
</script>

Writing a controlled program which, in turn, calls a client located HTML page which feeds additional content to the program.
I modified a function that checks internet status when the client-side html page (main.html) is accessed:
/* window.onload = checkOnline();*/
var netStatus=""
function checkOnline() {
if (navigator.onLine) {
netStatus = document.createTextNode("Internet is UP");
}
else {
netStatus = document.createTextNode("Internet is DOWN");
}
netstatusSpan = document.getElementById("mynetstatus");
netstatusSpan.replaceChild(netStatus, netstatusSpan.firstChild);
setTimeout("checkOnline()", 3000);
}
The script is intended to check there is an active internet connection.
If there is, it calls the hosted web page.
If there is not, it calls html content (either within the same Main.html or a second client-side html) that displays reduced content and the message that the internet is off-line. In addition, this client-side html continues to periodically test for internet connectivity every xxx seconds. When internets test positive, it launches the hosted html page.
What I am having difficulty with is the syntax to do this. (My example above simply displays a message)
I think I am trying to do a windows.open(http...) command in an If ELSE structure.
How to I issue the command to open the client-side html page when the internet is off-line. Complicating matters is I need to read a Windows system var which will have the path where the html file is located.
Thank you in advance for your assistance.

This is a strange problem that just started happening on one (and only one) of my computers, and I'm wondering if anyone has any insights.
I have a Website with hundreds of small jpeg files that I download into a Web page and display in a mosaic, a new image every second or so. This suddenly stopped working on one of my machines a few hours ago. I have no idea what I might have done or how to fix the problem. I rebooted my machine and I still get the error. The text that the exception handler returns is the following: "The Website may not be granting access to its files from your computer."
Not that it matters, but this is a Silverlight application that is reporting the error. I do have another application on the same machine (a WPF application) that accesses files from another folder on the same Website with no problem. And the Silverlight application displays my images just fine from another computer I have available.
I'm using the System.Net.WebClient class to download the images. In case you want to test whether this happens on your own machine, I'd be grateful if you tried it. As mentioned above, the downloads work fine on my other machine. The Website is here:
http://parisphototools.com
This is a Website that is under construction and is not yet fully functional, in case you try to Register on the Website for example.

In caption of the message it is displayed
"Photo Not Found",
So I think the photo named "splash800.jpg" is not
loading in the application from it's path.
(May be the path of the image of name of the image is wrong...)
Hope this will help!

Thanks for testing this. Obviously the problem is worse than I thought, and not just something that suddenly turned wrong on one of my machines (my development machine).
The "Photo Not Found" is my caption on my MessageBox, from my Silverlight application. All of the words after the word, "Reason" are from the exception handler in the event, System.Net.WebClient.OpenReadCompleted, which I call e. The expression, e.Error.Message supplies the words, "The Website may not be granting access to its files from your computer."
The URL I'm passing to WebClient.OpenReadAsync() is the following:
http:
If you type that URL into your Web browser, you will see the image pop up. So the paths I'm sending to WebClient.OpenReadAsync() are valid and the Website itself is not restricting access. The question then becomes, why all of a sudden is the call to WebClient.OpenReadAsync() failing on some machines? And why doesn't it fail on my other machine? The machine it's failing on is running Vista and the machine it doesn't fail on is running XP.
I must have done something in the Silverlight application that somehow is changing permissions that only affects some machines, and maybe it is operating system dependent.
Anyone have any ideas? What should I be looking for?

I figured out your problem, dude. You needed a clientaccesspolicy.xml file in the root of your Website. That fixed the problem.

This requires a bit of explanation.
My company's main website sits on a 64-bit server and runs under IIS6. The code libraries in the BIN folder were compiled using Visual Studio 2005 Professional, so they use the 2.0 framework. As far as I can tell, the code is 32-bit (I'm not sure how I would tell.) It is a complicated mess, with custom membership user and provider classes, new base classes for master and child pages, web parts, web controls, etc. However, it all works just fine.
We have some web pages that run on a 32-bit server because they use third-party components that, for whatever reason, are not cross compatable. They worked fine a few years ago when the main website was on a 32-bit machine, but caused lots of problems when we migrated. These components work when run standalone on the 64-bit machine, and the vendors insist they will work as web components in a fully 64-bit environment.
We are looking to overhaul our website. One of the projects will be to consolidate code libraries that have accumilated over the last six years, eliminate redundancies, etc. Since these would be rewritten anyway, discussion has turned to creating a fully 64-bit web environment, consolidating the two servers and ditch the 32-bit environment.
So, my questions:
Would we need a special version of VS to compile 64-bit code?
Would we need to upgrade IIS so that it will run as a 64-bit service?
Are there any caveats I should know about?
Is this an exercise in futility that will result only in me losing even more hair?
