I can't follow this waffle, but URL rewriting is easy, just write your own class to do it. Sounds like you're using other classes - why ?

It plainly makes no difference to performance, but it could make a difference if filenames clash.

How can I change password by email and new password?

How do you think ? How do other sites do it ?
You store a key which is passed in on the URL sent to the email address given, which then validates that they got the email.

Hi all
Creating menu controls dynamically using javascript in asp.net using c#
mokana

|

Is this the header of an article you're starting, or is it meant to be a question ? As soon as you create stuff in javascript, ASP.NET is irrelevant. You'd be insane to write your own menus, when you can find so many reusable ones with a simple google search.

Hi,
i need to know about 2 things.
1. Is there any way or article which shows u how to create a floating panel... that is consider a textbox to enter model name, somebody enters acer 1600 (acer brand, 1600 portion of model) and a panel appears (populated from tables 1. brand table 2. models)... Did you mean
Acer Aspire 1600
Acer Aspire 1600Z
Acer somemodelname 1600
and then a person choses one , this panel disappears, giving details of the model.. such panels are used in monster.com for login...
2. I am using linq and the sql table has 30000 rows, i know that i should do paging for the gridview but my client needs the application... he is not willing to give me time for that, project has been developed by somebody else and when u press search btn , it takes time to load the data, i want to insert a progress bar (it should not be a 0-100% progress bar... it can be something in javascript)...coming to the question... i simply added a label, just above the retrieval code, did the following
gridvu.datasource=null;
gridvu.visible=false;
lbl.text="Loading please wait";
but the previous gridview did not disappear, lbl was never displayed... Why?
thanx for helping...

Hello,
I am making first ever asp.net application and added lblusername,txtusername,lblpassword,txtpassword and btn signin in the master page for login purposes. i then provided functionality for the login (i have worked with desktop apps), when user found, copied his name to session and well, this worked...
but as i am still developing the application , i want my application to be signed in when i run it so i decided to provide the code in pageload of master page, which was there ( i don't know how this event was added) and it didn't work... searching through the methods and internet allowed me to know that there was a function onloadcomplete of page... i tried alot but i can't override this event... i don't get it in intellisense when i write override, also how do u add the init functions and events for a page...
Thanx for helping... i think, this question is probably very stupid but being a desktop application developer, i think asp.net can be very confusing...
please provid help

Hi, can u post your code?
If a user login in your page successfully log. then ur masterpage displayed
On your masterpage load event you can write this
txtUsername = sessiont("userName")

|

|

oh, Code!, i am working with a company and developing the application there for that i will have to wait till monday but there is nothing special in the code, ( (this portion was developed by previous programmer) masterpage.master has the login controls and a btn in a panel, this panel disappears when a successful login hapens and all the links appear , each link when clicked looks whether a session is created or not... simple as that... but as i have to continue developing it, i am thinking to add some code so that i am logged in when i run the application.. i can disable the panel and show the links panel directly but i don't want to do that, i want session to be created as soon as default.aspx loads but how ... that is where i need help...
thanx for replying

I have a gridview loaded from an sql datasource then in an item template in the gridview I have a dropdownlist that is supposingly loading from another sql datasource having the property datakeys of the gridview as its control parameter name.
meaning: each row has a ddl that takes its datakey as parameter to display results form another sql datasource;
and I have set the datakeynames of the gridview to be "OrderId" the pk that I want to use as the parameter. The idea is that I want to use the datakeys property of the gridview instead of selecteddatakey coz I want the user to have all data loaded once without the need to postback everytime he selects a row ...
the first sql datasource is loading the data into the gridview without any problem but when I assign the sqldatasource to the ddl the following error appears:
Type 'System.Web.UI.WebControls.DataKeyArray' in Assembly 'System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' is not marked as serializable.
code for gridview:
<asp:GridView ID="GridView1" runat="server" AllowPaging="True"
AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="OrderId"
DataSourceID="SqlDataSource1" CellPadding="4" DataMember="DefaultView"
ForeColor="#333333" GridLines="None" PageSize="15">
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:BoundField DataField="OrderId" HeaderText="OrderId" ReadOnly="True"
SortExpression="OrderId" />
<asp:BoundField DataField="FullName" HeaderText="FullName" ReadOnly="True"
SortExpression="FullName" />
<asp:BoundField DataField="Time" HeaderText="Time" SortExpression="Time" />
<asp:BoundField DataField="Comments" HeaderText="Comments"
SortExpression="Comments" />
<asp:BoundField DataField="Region" HeaderText="Region"
SortExpression="Region" />
<asp:BoundField DataField="Street" HeaderText="Street"
SortExpression="Street" />
<asp:BoundField DataField="PhoneNumber" HeaderText="PhoneNumber"
SortExpression="PhoneNumber" />
<asp:BoundField DataField="Total" HeaderText="Total" ReadOnly="True"
SortExpression="Total" />
<asp:TemplateField HeaderText="Order">
<ItemTemplate>
<asp:DropDownList ID="DropDownList3" runat="server"
DataSourceID="SqlDataSource3" DataTextField="LIST" DataValueField="LIST">
</asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#2461BF" />
<AlternatingRowStyle BackColor="White" />
</asp:GridView>
code for the ddl datasource:
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:ASPNETDBConnectionString %>"
SelectCommand="SELECT CAST(OrderDetails.Quantity AS varchar(3)) + ' ' + Menu.Name+ ' ' + CAST(OrderDetails.UnitPrice AS varchar(7)) AS LIST FROM Menu INNER JOIN OrderDetails ON OrderDetails.ItemId = Menu.ID WHERE (OrderDetails.OrderId = @OrderId)">
<SelectParameters>
<asp:ControlParameter ControlID="GridView1" Name="OrderId"
PropertyName="DataKeys" />
</SelectParameters>
</asp:SqlDataSource>
I want to load the ddl3 without the use of selectteddatakey(and the event selectedindexchanged) just with the help of datakeys and some code if needed and I will apreciate any help coz I am working on this for days and I'm beginning to think it's a bug coz everything seams to be ok untill the lovely error appears. be precise!I need your help, thank you

Hey all,
The RegistryKey refers to Microsoft.Win32.RegistryKey and I am on Windows Server 2003 with 64 bit. Do you all know if there is a reference for Microsoft.Win64.RegistryKey?
The code looks like this now...debugging it shows that the value of serverName is NULL(no kidding Wink )
<br />
public string RetrieveDataSource<br />
{<br />
<br />
get<br />
{<br />
try<br />
{<br />
System.Data.Sql.SqlDataSourceEnumerator en = System.Data.Sql.SqlDataSourceEnumerator.Instance;<br />
DataTable dt = en.GetDataSources();<br />
RegistryKey rk = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server");<br />
String[] instances = (String[])rk.GetValue("InstalledInstances");(This is NULL)<br />
<br />
if (instances.Length > 0)<br />
{<br />
foreach (string element in instances)<br />
{<br />
if (element != "MSSQLSERVER")<br />
{ serverName = String.Format(System.Environment.MachineName, element); }<br />
else<br />
{ serverName = System.Environment.MachineName; }<br />
<br />
}<br />
<br />
}<br />
<br />
}<br />
<br />
catch (Exception ex)<br />
{<br />
ex2 = ex.Message;<br />
}<br />
return serverName;(This is NULL)<br />
}<br />
<br />
}
Is there any other way of getting the instance name without this roundabout? Seemed pretty straight forward to me before i coded...now not so much.
I can get the machine name directly by System.Environment.MachineName; if only there is a way to retrieve Instance name without RegistryKey hassle..i would avoid this method totally.
Thanks to Sandeep, Rolcr, Disgyza and Colin Angus Mackay for helping

I posted this on a different thread of yours but I figured I'd post it here as perhaps a different approach to your problem. I'm not entirely sure if this will work for you, but you can certainly give it a shot.
You could try using this:
using(Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer m = new Microsoft.SqlServer.Management.Smo.Wmi.ManagedComputer())
{
foreach (ServerInstance si in mc.ServerInstances)
{
Response.Write("ServerInstance:" + si.Name + "
");
}
}
You'll probably have to add a Reference to Microsoft.SqlServer.Smo
Best of luck
Cheers

Though it seemed like it would work, it showed error in ServerInstance keyword. Added a bunch of assembly reference
using Microsoft.SqlServer.Management.Smo.Wmi;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Smo.RegisteredServers;
Looks like i'm pretty close, if only i could figure out how to find the sql server instance running, i'll be all set to post an article about the exercise
