How to make left side menus

Hello friends,

I'm entering the ASP.Net technology World and I have some beginer questions, so please, don't be too hard Wink | ;)

Ok, I need to do a "left side" menu. I have a table with main categories and other table with subcategories related to its main categories.
In the old ASP I just iterate with two "for", one for the main categories containing the other for the sub-categories belonging to the current category.
Quite easy, just put the ASP code in the right part of my page and I have my menu.

But in ASP.Net and the code-behing pages I don't know how to o this, because I can't put the ASP.Net code embebed into the HTML code.

I know this should be a very thumb questoin but....everybody has a begining Smile | :)

Thanks a lot

I am trying to debug an asp.net vb.net project on an XP machine.

When I start to debug I get this error:

Error while trying to run project: Unable to start debugging on the server. You do not have permissions to debug the server.

Verify that you are a member of the 'Debugger Users" group on the server.

I am certain that I am a member of the Debugger Users group. I am also a member of the Administrators group (as Help suggests).

I tried everything in the help file and nothing worked. Does anyone have any suggestions ?

Value in auth cookie

Hi,

I have built my own authentication system which uses a cookie to save the info about the user. All works fine until I want to retrive the info from the cookie. If the name of the cookie is the same as FormsAuthentication.FormsCookieName, the cookie cannot contain any value I want, because if the cookie contains any nonvalid values then the cookie will not show up in the Request.Cookies collection. I first put the value “a” in the cookie, and all works fine, then “b”, works fine, but if I combines them , “ab”, then the cookie wont show up in the Request.Cookies collection. What values can the auth cookie contain?

(ASP.NET 2.0)

Below is the code to test this.

Default.aspx:

<br />
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" Title="Untitled Page" %><br />
<html><br />
<head><br />
    <title>test cookie</title><br />
</head><br />
<body><br />
<form id="form" runat="server" action="test.aspx"><br />
<asp:label id="cookievalue" runat="server"></asp:label><br />
<asp:button text="set cookie" id="setcookie" runat="server" OnClick="setcookie_Click" /><br />
</form><br />
</body><br />
</html><br />

Default.aspx.cs

<br />
using System;<br />
using System.Web;<br />
using System.Web.Security;<br />
<br />
public partial class _Default : System.Web.UI.Page <br />
{<br />
    private string _cookieName;<br />

    {<br />
        _cookieName = FormsAuthentication.FormsCookieName;<br />
    }<br />
<br />
    protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        if (Request.Cookies[_cookieName] == null)<br />
        {<br />
            Label1.Text = "no cookie";<br />
        }<br />
        else<br />
        {<br />
            Label1.Text = Request.Cookies[_cookieName].Value;<br />
        }<br />
    }<br />
<br />
    protected void Button1_Click(object sender, EventArgs e)<br />
    {<br />

        Response.Redirect(Request.Url.PathAndQuery);<br />
    }<br />
<br />

    {<br />
        HttpCookie cookie = new HttpCookie(_cookieName, "ab");<br />

Any thing equivalent to "eval" in ASP.NET?

eval is the system defined method in Javascript.It will return the object if a string is passed as argument.
Eg eval("Textbox1")returns me the control object.Is there any equvalent method in ASP.Net?

No.

There are other ways of doing similar things, depending on what you want to do really. You have access to the compiler dll, so you can actually compile code in the runtime. You can use reflection to create objects if you know the class name, and to access members of objects. If you want to find a control in the current page, there is a FindControl method.

I am converting a DELPHI application to VB 6.0. Language in the DELPHI Project is PASCAL. In the application coder has created a TMemoryStream type. I just want to know what is its equivalent in VB 6.0

The complete code is -

<br />
function TForm1.BackupFinger():integer;<br />
var<br />
bRet:boolean;<br />
iRet:integer;<br />
jh:integer;<br />
dwMachineNumber,dwEnrollNumber,dwEMachineNumber,dwBackupNumber:integer;<br />

buf: array[0..800] of longint;<br />
m:TMemoryStream;<br />
begin<br />
jh := StrToInt(cbJh.Text);<br />
d1 := 0;<br />
d3 := 0;<br />
dwMachineNumber := jh;<br />
dwEnrollNumber := qfp.FieldByName('dwEnrollNumber').Value;<br />
dwEMachineNumber := qfp.FieldByName('dwEMachineNumber').Value;<br />
dwBackupNumber := qfp.FieldByName('dwBackupNumber').Value;<br />
bRet := FPKeeper1.GetEnrollDataB(dwMachineNumber,dwEnrollNumber,dwEMachineNumber,dwBackupNumber,d1,buf[0],d3);<br />
if bRet = true then<br />
begin<br />
m := TMemoryStream.Create;<br />
m.Position := 0;<br />
iRet := m.Write(buf,800);<br />
qfp.Edit();<br />
qfpdwEnrollData.LoadFromStream(m);<br />
qfp.FieldByName('dwPassWord').Value := d3;<br />

m.Free;<br />
BackupFinger := 1;<br />
end<br />
else<br />
begin<br />
BackupFinger := 0;<br />
end<br />
end;<br />

Please help if someone has any idea about this.

Solution1 :- Enable view state of the control,so that the value is retained.The popup containing textbox should in the same page where the label is present.This will help u in retaining the contents.

Solution2 :- Store the data in a hidden box and reload the control again with the contents.

try this

for (var i = 0; i < states.Tables[0].Rows.length; ++i)
{

document.getElementById("ddlState").options[document.getElementById("ddlState").options.length] = new Option(states.Tables[0].Rows[i].StateName, states.Tables[0].Rows[i].StateId);
}

or
document.getElementById("ddlState").options[0] =value;

Hi Ashutosh,

Thank you for your reply.

Can I please know what "ddlState" is? Is it the name of the Listbox I want to display the words, or the control that has the sentance?

If it is the Listbox, where can I pass the sentance? And should I use something to split the sentance first?

Thanks,

Re: Insert values into Listbox with Javascript

yes ddlState is a id of dropdownlist.

value is a variable through which we can insert data into list.

Hi Ashutosh,

Sorry, I'm still not very clear about these codes
Does it work the same for ListBox as well?

So what is "states"? Is it a name of a talbe or a DataSet or something?

Aashutoshkumar wrote:
for (var i = 0; i < states.Tables[0].Rows.length; ++i)

What about "StateName" and "StateId"? Are these some kind of a property or it will be the Name and ID of the DataSet?

Aashutoshkumar wrote:
document.getElementById("ddlState").options[document.getElementById("ddlState").options.length] = new Option(states.Tables[0].Rows[i].StateName, states.Tables[0].Rows[i].StateId);

How about the "or" is it a part of the code or it's the next line of the code will do the same thing as the codes above, so it is another option for me?

Aashutoshkumar wrote:

or
document.getElementById("ddlState").options[0] =value;

Thank you for answering me. And sorry about the trouble, without understanding them I can not modify them and customise into my codes.

Thanks again,

How to scchedule sending feedback mails

Hi,

I run a web portal where people buy tickets online. I am interested in taking their feedback 2 days after their journey. This requires me to send mails everyday to get their feedback.

I created a HTML format mail which can be sent. As of now, Everyday I use a small web page and a submit button to send mails to those who have travelled. But How can I automate or schedule so that these mails are sent regularly.

Is there any scheduler or can we do any automation in ASP.NET?

Thanks

Hi Sudhakar,
I have a suggestion. Create console application and write a code for Send Mail In C#
Like

using System.Web.Mail;
using System.Windows.Forms;

// Create a function

public SendMail()
{
MailMessage objMail = new MailMessage ();

objMail.From = "ABC@gamil.com"
objMail.To = "PQR@gmail.com;

objMail.Subject = "This is Test Mail;
objMail.BodyFormat = MailFormat.Html ;
objMail.Body = "Hi ,This is a test mail for you;
try
{
SmtpMail.Send (objMail);
}

catch (System.Web.HttpException exHttp )
{
MessageBox.Show("Exception occurred:- " + exHttp.ToString() ) ;

}
finally
{
objMail = null;
}
}

Write Body in HTML Format.A good idea is store all email who have travelled in XML and read from XML and send Mail to Client.
To schedule sending email every day .Windows schedule help you.I Mean to say you can shedule exe in windows schedular.If u need code then let me know i will send.
I hope this will you.
