If you are new to programming then I would suggest the first thing you need to learn is the basics of Web based programs; http://www.asp.net/[^] would be a good place to start.

Good day all - hope it finds you well! We are exploring the possibility of developing a web (IIS world) front end for a legacy application and are looking to understand the best platform / tools / languages / etc. in which to build said front end that collects and presents data to the user as well as pass / receive responses to a back-end DB and detached processes. Additionally it seems we will likely need to be able to potentially receive async data updates (status change for example) and post to the page the user is viewing.
Thanks in advance!

I am trying to get my code to check the “username” field and print an error message letting the user know that they left a field blank. Now before all I had was the below code of which it worked in part, in the sense that the below code was executed when the submit button was clicked on and when the page was refreshed.
if (isset($_POST['username'])) {
emptyField();
}
function emptyField()
{
$var1 = "">*Field missing entry...";
echo $var1;
}
To fix this I the added the below code, which now meant that the code only worked if the user clicked on the submit button and didn’t work if the page is refreshed. However I’ve also noticed that even when there is text in the “username” field and say the user got there password wrong (not proceeding to the next page), it simply cleared all fields and printed “*Field missing entry...*” Why is this and how do I sort this out…?
<?php
if(isset($_POST['submit']))
{
fieldChecker();
}
function fieldChecker(){
if (isset($_POST['username'])) {
emptyField();
}
}
function emptyField()
{
$var1 = "">*Field missing entry...";
echo $var1;
}
?>

Try..
if (empty($_POST['username'])) {
emptyField();
}
|
|
|
|
|
Thanks...That worked... 
|
|
|
|
|
This code will help you please try:
if (empty($_POST['username'])) {
emptyField();
}

In the following code snippet if I change the port number from 587 to any other (even to 465 as mentioned over the net) the mail sending attempts fail.
string from1 = "from_e-mail";
string to1 = "to_e-mail";
string subject = "Test";
const string password = "xxxxxxxx";
string body = "Hello World";
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.EnableSsl = true;
smtp.UseDefaultCredentials = false;
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.Credentials = new NetworkCredential(from1, password);
smtp.Timeout = 20000000;
smtp.Send(from1, to1, subject, body);
Any Suggestion

The most important suggestion:
Tell us the error message!
|
|
|
|
|
The problem is that noting happens. I believe connection is not getting established.

Sounds like connection timeout issue. Make sure that the connection is active and above for a good period so that your bulk records are easily transferred.

Hi friends,
I want to build web based app to display data in chart.
that data it will be csv file and then import to sql database and then process by asp .net with output chart display.
Anyone can help?or give me reference..
Thankyu.

You have two processes, don't complicate things by joining them together. Attack each problem separately. First, figure out a way to get your CSV into the database - should be fairly simple. Do you need users to upload the CSV through the web site or can you use BCP on the SQL Server to load it yourself? Answer questions like that and then you can start to tackle the CSV import problem.
Once you have the data in the database, or at least you are sure of the database schema, you can start to design your charting tool. I suggest using an existing charting library like one of these...
Google Charts[^]
Flotr2 Charts[^]

Basically I need this DHTML popup to show once per 12 hours for the visiting user. I can't seem to figure it out...
This is in the code for the pop:
<script type="text/javascript">
var dragapproved=false

function drag_drop(e){
if (ie5&&dragapproved&&event.button==1){
document.getElementById("dwindow").style.left=tempx+event.clientX-offsetx+"px"
document.getElementById("dwindow").style.top=tempy+event.clientY-offsety+"px"
}
else if (ns6&&dragapproved){
document.getElementById("dwindow").style.left=tempx+e.clientX-offsetx+"px"

Any help would be appreciated. thanks

I have created a elevator functionality [there are 2 floors and corresponding to each one , there is a checkbox. Depending upon which checkbox is checked, the elevator should move to that floor.
Only thing which i am not able to implement here is:
Make the checkbox check automatically and slowly fadeout to unchecked state when the orange elevator has reached that checkbox.
Here is the link to the markup and script: http://jsfiddle.net/hurricaneankit/qR4uJ/

Hmmm... i would use a loop (for / next) to change the Color from yellow to the background in small steps and the opposite way to fade it in on the other box...

For your animate() function, you can pass in a function to execute when the animation is completed. You can't "fade" your checkbox, but you can un-check it.
$(function(){
$(document).ready(function () {
$("#check1").click(function () {
$("#check1").toggleClass('checked');
$("#check2").removeClass('checked');
$("#groundDiv").animate({
"top": "0px"
}, 1000, function () {
});
});
});

How can sites developed in php or any other language be integrated into a downloadable mobile web application
|
|
|
|
|
PHP is an ServerSide Language and can not run in the Browser like an HTML File that you open... To Use PHP you allways require an Webserver that supports PHP (i am not aware if there is an Xammp installation for Mobile devices...)
Also, Mobile devices are using different Brwosers and different OS's.
As long as you do not specify what kind of Mobile Devices you want to use, HTML5 or/and Java would be the most flexible way.

Hello! I have a problem for you guys
*Sorry for my English I'm French 
I would like to build a stage composed with three superimposed plans.
The background is a set which can contain arbitrary graphic elements, by an image or a series of images.
The median plan is a time line on which are aligned objects (symbolized by icons)
The foreground allows the display in close-up of an object, accompanied with a note.
The navigation in the page is made with the scroll (horizontally or vertically).
Both plans of the background move by respecting an effect of parallax, the closest plan moving faster than the plan in the back which give a deep impression..
When a icon situated on the time line passes in the center of the window, it is " intercepted " and placed from the point of view of focus.
When an object is on this plan, it is associated with a note wich give its definition.
Here's an image:
http://www.freeimagehosting.net/3u11g[^]
The problem has 4 parts:
1) Find a method to make a scroling of the graphic elements (Parallax?)
2) Determine if an icon of the line of time line is in the middle of the window
3) Resize the icon and show the associated text.
4) Move the HTML element associated with the icon of the branch
DOM " Time line " towards the branch "Focus ".
