Hi,
Here are some suggestions...
Logistics System sujected to Shipping Line.
You can implement the activities involved in a Shipping Line covering the basic work flow, might be able to get some idea by studding the logistics domain..
Online Shopping Site.
You can create a shopping store for selling goods. So here you will have the e-commerce features you would see in any online shoppping site.
Web Portal.
A web portal for a company. This could automate the HR managemnt plus, automating some divisional activities based on the company you select.
A Content Managment System.
Thx,
Gayani

Advance project not only mean the advance topic , it can be simple also, but the main thing is that how did you implement it.
Menas
1. Layer Architecture , that how did you layred your application with Bussiess Layer, Presentation Layer , Database layer
2. Different Advance Components like Ajax, Silverlights etc.

Hi,
There are many more advance topic available on the internet you can get from like Credit Scoring Engine,Cargo management system etc...
But the main thing is ,How you represent them.Even yopu vcan make a very normal topic like ONLINE HOSPITAL MANAGEMENT and represent it in some unique way that will surely catch one's eye easily.
Some point you can take care
* Try to use some advance technology to provide better and advance GUI.
* It should be more user friendly
* Better color combination
etc...
Hope you got my point..
Best of luck for your endeavors.
Cheers!!

Look at http://www.pageflakes.com/[^]. It's an innovative concept. You can choose something similar to that.

Hi navanneeth , great link !!!!!

I wish to enable/disable the button that moves to the next page in a wizard. I want it initially disabled, then enable it based on a user choice (checkbox acknowledging terms) in the wizard step.
Also, I have other controls I wish to change when the checkbox is changed. Lastly, I only wish to update those few controls and not the entire page.
I started by wrapping the checkbox and other controls to change in an UpdatePanel. This solved my "only update necessary controls" issue. But, I couldn't update the wizard button. So, I wrapped that button in a separate UpdatePanel and updated it from by Checkbox_CheckedChanged function.
This all works fine (only updating necessary controls, enabling/disabling Next button correctly) except that the button to move to the next wizard step no longer works. I presume this is becuase it is wrapped in an UpdatePanel. It appears to actually generate the data for the next steps/pages (hits the database, etc.), but it just doesn't update the page.
Let me see if I can include some meaniningful code:
<StartNavigationTemplate>
<asp:UpdatePanel ID="upnlStartButton" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<asp:Button ID="StartNextButton" CommandName="MoveNext" runat="server" AlternateText="Start Writing Letter" Enabled="false" Text="Start Your Letter" />
</ContentTemplate>
</asp:UpdatePanel>
</StartNavigationTemplate>
<WizardSteps>
<asp:WizardStep runat="server" Title="Terms and Conditions" StepType="Start">
<div style="margin-left: 10px; overflow: auto; width: 559px; height: 350px">
<asp:Label ID="TermsAndConditionsLBL" runat="server"></asp:Label>
<br />
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:CheckBox ID="agreeTermsCHBX" runat="server" Text="I Agree" AutoPostBack="True" OnCheckedChanged="agreeTermsCBX_CheckedChanged" />
<br />
<asp:CheckBox ID="disagreeTermsCHBX" runat="server" Text="I Disagree" AutoPostBack="True" OnCheckedChanged="disagreeTermsCBX_CheckedChanged" />
</ContentTemplate>
</asp:UpdatePanel>
</div>
</asp:WizardStep>
protected void agreeTermsCBX_CheckedChanged(object sender, EventArgs e)
{
if (agreeTermsCHBX.Checked)
{
disagreeTermsCHBX.Checked = false;
((Button)findControl(wizard, "StartNextButton")).Enabled = true;
((UpdatePanel)findControl(wizard, "upnlStartButton")).Update();
}
}
Is there a way to make the wizard page update? Is there another way to accomplish my task (only update certain controls, enable/disable wizard Next button)? This didn't seem like a diffcult task, I feel like I am missing something obvious
Any suggestions are welcome.

why dont you use client end javascript to do this job...
just use
var ctrl = document.getElementById('controlid');
ctrl.disabled='disabled';
simple...

Sir,
I am a new one to ASP.NET. I have to do a project as part of my studies. I preferred ASP.NET and I like to make a web site like Orkut (A social networking site). I consulted a web developer and he says that I should host the proposed project for it to be working.
I want to complete it in ASP.NET without hosting and I just want to show the demo to the examiner. Please reply whether I can demonstrate the project to a person without hosting it.
I REPEAT THE QUESTION:
"IS IT POSSIBLE TO DEMONSTRATE THE WORKING OF A SOCIAL NETWORKING SITE LIKE ORKUT AFTER COMPLETING THE CODING AND WITHOUT HOSTING IT?"
Hope u reply soon

You can create virtual directory on your local IIS[^]

Hi
You have various ways to do you project for your studies
1.Yes you need to have a atleast internet connection to your computer in which you are developing you website just host the website in localhost.
secondly you can use a teamviewer software which help you to connect to your computer which is there in your house and you can see desktop of your computer in your examiner system or laptop but you need to install the software in both systems (in your house and as well as in your examiner systems) when you connect this software it creates a unique session where you can show your home desktop in your examiner laptop and show the project that you have created
Best of luck

Don't use words like urgent, it is just flat out rude

Don't shout, that is just as rude. Now, to your question. You don't need to have a webhost for a demo, just use IIS locally.

The odds of you writing a site like Orkut appear to me to be hovering around zero.
You can host it locally, but, of course, no-one can see it, so it will be hard to prove it works when the point of it will be having a number of users interacting with each other. You sure can't prove your site will work in the sense of being written to handle concurrent users, etc, that way, unless people on a LAN all connect to your machine as a web server for the test.

Are the receipients of this demonstration fluent in ASP.NET? If so, Visual Studio has a lovely look and feel

Hi,
i'm using drawing.printing in winforms and recently i've implemented it to one of my ASP.NET projects.
on the first look when i ran it on the Webdev.Webserver (created instance by the VS2008) the printing worked great.
when i used it on the IIS, 6 or 7, it stopped with error on user permissions.
after restarting the IIS with the same User as the Webdev.Webserver using, the IE just get stuck with no error exception - just looping until i stop it.
does anyone know how can i work it out ?!?
Thanks in advance,
Amit

Have you found any good article? If I recall, there are some around here.

One of the Best Link

Abhijit Jana wrote: One of the Best Link

No that's not the best link. It's not AJAX, it is talking about AJAX toolkit developed by Microsoft for ASP.NET applications. AJAX is just javascript and this[^] is a good beginer level tutorial which talks about AJAX.
Don't know why people are thinking AJAX is developed by Microsoft

Hi Rameez
You can do it by installing a Asp.net Ajax toolkit which is available from microsoft website which is free to download and install if you are using asp.net 2.0 or visual studio 2005 after installing this small utility you will see a new option comes when you select a new web site from a file menu and there you can select AJAX ENABLED WEBSITE.
you will also see some new tools in your toolbox like update panel and script manager just using this two things you can build your website ajax enabled
Happy Coding

you can also use Javascript XMLHttpRequest Object to access AJAX directly...
use W3School's AJAX Tutorial for your start...
http://www.w3schools.com/Ajax/Default.Asp[^]
Its good way to understand what AJAX exactly is... .and how can one use AJAX to avoid unnecessary postbacks...

Here is the demo for live control tool kit.In this they have list all the controls demostrating how it appears and the code you need to use..

hi guys! briefly, i have an application which use an api for its interaction with another plattform.at this point a need to update my database with data from a call from that api which uses querystring to pass data.Simple and fairky straight foward but couldn't suceeded.and the funniest is it doesn't throw any error. tried for 3 days now to find out where the problem is without any changes.i'm sure it just a little thing but can't see it.i would like to ask for help on this. here is my codes
the page call.aspx that the api use as callback to pass the data is.
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
gid = Request["Id"];<br />
numbstatus = Request["status"];<br />
if(apimsgid != null && numbstatus != null)<br />
{<br />
gid = gid.Trim();<br />
numbstatus= numbstatus.Trim();<br />
if (gid != "" && numbstatus != "")<br />
{<br />
DatabaseLayer dlayerobj = new DatabaseLayer();<br />
<br />
Response.Write(dlayerobj.UpdateStatusByApiId(gid, numbstatus));<br />
}<br />
}<br />
<br />
}<br />
}<br />
<br />
now the function in the database layer is :
public string UpdateStatusByApiId(string theapiid, string thestatusnum)<br />
{<br />
string status = convertStatus(thestatusnum);<br />
try<br />
{<br />
SqlCommand updatecmd = new SqlCommand();<br />
updatecmd.CommandType = CommandType.Text; <br />
updatecmd.Connection = con;<br />
updatecmd.CommandText = "update TState set DStatus =@stat where Gid=@apid"; <br />
updatecmd.Parameters.Add("@stat", SqlDbType.VarChar, 20).Value = status;<br />
updatecmd.Parameters.Add("@apid", SqlDbType.VarChar, 128).Value = theapiid;<br />
updatecmd.ExecuteNonQuery();<br />
return theapiid + " : " + status;<br />
this also to see if the fucntion receives its param well and it receives it<br />
}<br />
catch (Exception ex)<br />
{<br />
misc.logerr(ex.ToString());<br />
return ex.ToString();<br />
}<br />
<br />
<br />
}<br />
please let me know cause i'm stacked here and can't move forward without this..
ps:can anyone tell me the best practice testing in debugging.i mean by that either using an hyperlink or from address bar
eager to learn
