The error message is straight forward. Well, where is this find.aspx resides? Can you show the code you used for rewriting?

public class SimpleRewriter : System.Web.IHttpModule
{
..
void context_BeginRequest(object sender, EventArgs e)
    {
string newUrl = UrlEngine.Engine.ToRealUrl(_application.Context.Request);

       HttpContext.Current.RewritePath(newUrl, true);
}
}

If _application.Context.Request be

mySite/Sale

newUrl get

/Find.aspx?type=Sale

value.
Find.aspx is in Root Directory:mySite/Find.aspx

A guess. Try passing false to RewritePath method?

HttpContext.Current.RewritePath(newUrl, false);

It rises error yet:

Server Error in '/MySite' Application.
--------------------------------------------------------------------------------

The resource cannot be found. 
Description: HTTP 404. The resource you are looking for (or one of its dependencies)
could have been removed, had its name changed, or is temporarily unavailable.
Please review the following URL and make sure that it is spelled correctly. 

Requested URL: /MySite/Sale/find.aspx

I think i must change /MySite/Sale/find.aspx to /MySite/find.aspx.
It means i must rewrite Relative Path of httpCuntex.But I don't know how?

Hi!
I have this strange requirement.
I need to restrict users to a website from certain machines. MAC address is stored in the database and should be validated before authenticating the username/password.
Can you provide me any suggestions about how to do this?
I have been told to create a dll and call it from javascript. Is this possible or what?
Any help will be highly appreciated.
Thanks..

That's only possible if the dll is a registered COM server. For more info see this thread: http://p2p.wrox.com/topic.asp?TOPIC_ID=18052

I didn't get your question. When one add the dll as refernce in project then the dll's class is accesible from all the codebehind files in that project.Please check the namepace of the class that dll is giving.

Cheers!!

Strange problem in ASP.NET

We have a FormView control to show customer information with paging enabled in an .aspx page named Customer.aspx. We can navigate page by page to show customer information per page. FormView datasource has been a SqlDataSource control which is calling a stored Procedure. And FormView dataKey has been set to be customerID.

Now in this page FormView nevigation is working well showing customer page by page order by their names.

We have another page named Sales.aspx, from which we can get back to our previous page named Customer.aspx by clicking a button. At this time we are taking a particular customerID in Session and calculation the rowid/position of this customer [with an order by query which is the same with the stored procedure of FormView Datasource]. Now we are doing

FormView1.PageIndex = CustomerPosition;

So that we can directly go to the FormView page where this customer is and as FormView datakey is the customerID we can view this particular customer data in that FormView page.

Instead of this we are having a wrong customer data in that page of FormView. What is more interesting here that not every time this is happening……sometimes it is working fine showing correct customer information in FormView pages and ‘Next’,’Previous’ working fine with correct results. Here by correct customer I mean that particular customer which belongs to that FormView page. We have checked our log file. There we have found out that after FormView pageindex has been changed, sometimes (randomly) FormView.selectedvalue is wrongly referring to a different CustomerID which was not the correct one.

The whole behavior is completely random and does not have a recognizable pattern. Sometimes (randomly) FormView.selectedvalue is choosing a wrong value and it’s a read only field. While running it at our local boxes, the frequency of error is less whereas frequency of error is more when we are running it at our server. We are using windows server 2003, Sql server 2005 and IIS6 and ASP.NET 3.0

Any suggestions will be greatly appreciated. Thanks.

Double check your sort. Does the order by clause guarantee the same sort every time? If they column list does not include at least one unique value, the answer is no. I ALWAYS include a unique column such as the PK in the sort as the last column if nothing else, when creating stored procs that return records.

Add the PK in your sort.

You can handle the "TextChanged" event of the "Textbox". so whenever user changes the date. you can handle the event using TextBox.Text Property.

Select the Textbox which bound with the Calendar Extendar, then go to Property window, Select Events and find the "TextChanged", double click and code for .Text Property. Done.

Hi everyone,
I wish to know ..is it possible to create a mail application without opening a new port?I mean I wish to embed this functionality in a sharepoint site which is already using one port and the security restrictions dont allow us to open a new port.Can we use the same port simultaneously to use this mail application? Confused | :confused:

The only port necessary for SharePoint is 80, standard HTTP, what port are you talking about? Sending an email doesn't require a port to be opened, unless your SharePoint box is also the SMTP server, in which case it would be a bad idea.

Hindi text font must be installed on client computer. Otherwise it will display some non-readable text.

Try saving the image of HindiText and display that on webpage. It will never create problem.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
