Hi there,
I'm trying to create bar-graphs that track a students progress a series of tests. Nothing fancy, just bar graphs for 5 different subjects. Y-Axis to contain marks and X-axis date on which the tests were taken. The results will be stored on an SQL database.They may/may not post a link to the graphs on their blog so that when the page loads, the graph should show up.
Any idea which product can do this for me? I had a look at Dundas and .netcharting but both have far more features than i need. Not to mention they waaaay too expensive  I just want to display the graph subject wise or all subjects on the page a la Google analytics.
Any suggestions?

Hello Everyone,

"Some formatted text like bold italic and etc"
Actually i'm creating my own emailEditor through which i can bold,italic and etc. facilities being provided.
And it's working great but as i'm sending normal text it's but as i provide some formatted text it's not..................
The code i'm giving below for sending mail.........
//For Sending The Mail

mail1.From="manoj.manojbisht@gmail.com";
mail1.Subject="Mail From Manoj Bisht";
mail1.Priority=MailPriority.High;
mail1.BodyFormat=MailFormat.Html;
string body=HtmlTextArea.Value;
mail1.Body=body.ToString();
try
{
SmtpMail.SmtpServer="127.0.0.1";
SmtpMail.Send(mail1);
lblMsg.Text="Mail Sent Successfully";

I think you need to turn the event validation on the form off.
I didn't get any requirements for the signature

Hi Guru's
Im using ObjectDataSource for filling up the GridView, I'm just moving in on using objectDataSource, I find it handy since it trims up my code. After placing the requirement I'm encountering this issue No parameterless constructor defined for this object.
Please let me know what when wrong?
Regards
Dom

The class doesn't have a zero parameter constructor. Some object that you are using requires a zero parameter constructor (even if it doesn't use it).
Deja View - the feeling that you've seen this post before.

Here's the deal. Any serializable object must have a parameterless constuctor. For the Object Oriented beginner that means.
Class MyDataOject
{
public MyDataOject()
{
//parameterless consturctor
}
}
This is so that the object can be serialized to XML. Also you can not not have read only properties for the same reason. If a property is read only you can't recreate the object from xml. The objectDataSource probably serializes your class behind the scenes.

SP for the function above:

<br />
alter PROCEDURE nw_spSelectOrders <br />

<br />
)<br />
as<br />
begin<br />
<br />
Select o.orderID, <br />
od.quantity, <br />
od.unitprice, <br />
od.unitprice <br />
from orders as o<br />
left outer join [order details] as od<br />
on o.orderid = od.orderid<br />
where case when @orderID = 0 then 'selected'<br />
else<br />
case when o.orderID = @orderID then 'selected'<br />
else 'not selected'<br />
end <br />
end= 'selected'<br />
end
Whats wrong with passing 0? when I explicitly place orderID number I get result but passing 0 nada..
Please advice
Thanks Guys

Uhh please advise what? The error is REALLY descriptive, and two people here have given you the answer.
I advise you learn .NET or something, if you can't even figure out what a paremeterless constructor is.

|
|
|
|
I don't mean to be harsh all of us do start from baby step, those two people has given helpful suggestions and you.. you simply throw snow ball and say I advise you learn .NET or something ... or something?? WAD!
Big help anyways

I am using RegisterStartupScript to run a javascript and display a modal web form from my code behind page. In vb.net the code is:
strScript = "<script> OpenWebPrompt('The party size and quantitative/qualitative answers require that this request be cancelled. Please speak to a client id for further guidance.','www.cnn.com','Reset','Abort','','');</script>"
Page.RegisterStartupScript("OpenWebPrompt", strScript) where OpenWebPrompt is a javascript in this page.
When the form is displayed all looks OK, but a button is clicked, another instance of the form is displayed and only then is the vbscript of the web form called. I am a new web programmer so i apologize if this is a simple question.
The javascript is:
function OpenWebPrompt(msg, hlink, btn1, btn2, btn3, btn4)
{
var sOptions;
sOptions = "center: Yes; dialogHeight: 550px; dialogWidth: 720px;";
var oArgs = new Object();
oArgs.msg = msg;
oArgs.hlink = hlink;
oArgs.btn1 = btn1;
oArgs.btn2 = btn2;
oArgs.btn3 = btn3;
oArgs.btn4 = btn4;
var url = "../convertedcontrols/webprompt.aspx?msg=" + msg + "&btn1=" + btn1 + "&btn2=" + btn2 + "&btn3=" + btn3 + "&btn4=" + btn4 + "&hlink=" + hlink;
var w = window.showModalDialog(url,"",sOptions);
var objVal = document.getElementById("<%=Me.UniqueID%>_txtPromptReturn");
objVal.text = w
//document.forms(0).submit();
// return w;
}
The webform is:
<%@ AutoEventWireup="false" Codebehind="WebPrompt.aspx.vb" Inherits="CSFB.WebPrompt" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>

end sub

RegisterStartupScript will register your javascript and will call when form gets loaded. i think you are also calling same function on button click event . What you have to do ?
Thanks and Regards

Hi all,
i have a page with a button on it, onclick of button i need to get a string data from database and need to write that to a word file. my code is like this:-
1) function:- i am calling this function on button click event after getting my data from database, suppose data is a string "someString".
i am bound to use this approach only because of some specific requirements(can't use word file writing with word application and document object...)
private void html2word(string someString)
{
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.ContentType = "application/msword";
HttpContext.Current.Response.Write(@"");
HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;filename='InvDetails.doc'");
HttpContext.Current.Response.Charset = "utf-8"; //UTF8
HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.GetEncoding("windows-1250"); //windows-1250
HttpContext.Current.Response.Write("");
HttpContext.Current.Response.Write(someString); HttpContext.Current.Response.Write(" ");
return HttpContext.Current.Response;
// this flush() line of code will ask user to open or save a word file, here only i want to save this file without prompting the user, as this file is going to be deleted after some operation and hence user should not know that it is created... how can we do this 
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}

Hi All,
Is there any relationship between Cookies and Session.Abandon()???
Is am implementing Remember Me on this computer on login page and store the user name and password in Cookies. It works fine if I logout from my site but if I close my application and again run then it doesnot maintain the cookie values.
Please help me...

Hey sorry for late reply
Can you post the code where you are adding cookie from server side
see this it is working fine in my machine sequence should be like this only specially for expiry  i think it should work now
<br />
HttpCookie cookie = new HttpCookie(TxtBxUserName.Text);<br />
Response.Cookies.Add(cookie);<br />
cookie.Values.Add("",TxtBxUserName.Text + "|" + TxtBxPassword.Text + ";");<br />
Response.Cookies[TxtBxUserName.Text].Expires = DateTime.Now.AddDays(15); <br />
<br />
Thanks and Regards

i want to display videos in browser in a website.
any suggestions.........
Do good and have good.
|
|
|
|
|
The easiest way is to use youtube Saves bandwidth
|
|
|
|
|
This all depends on the format of the video as to the exact method.
However it basically intails embedding the appropriate vide player into the html code. This code is available readily on the web, and can be done automatically (i think) via tools such as dreamweaver.
This is assuming you have an pre-encoding video file? If not you will need to encode it to your chosen format using the appropriate encoding tool for the format you wish to use.
However this is essentially quite a basic process, so id be a little concerned that you are asking this in a .Net forum.
