Just try to debugg your application by putting break point to your line of codes and check what value are you getting here
a-+s-+p-+ wrote: string help = Request.QueryString["help"].ToString();
There is no need of calling ToString() method
Request.QueryString["help"].ToString();
as Request.QueryString["help"]; returns string
and try to use String class method and properties like
String.IsNullOrEmpty / String.Equals instead of Checking for null and comparing two strings
I think this is the best way which can help you now and in future also 
Thanks and Regards

If you want to check if the string is null or empty, the String.IsNullOrEmpty method is ideal, but if you only want to check if the string is null, that can not be done any other way than just comparing with null.
The == operator is overloaded in the string class so that you can use it to compare strings. This is the intuitive way of comparing strings, and it works just fine. The String.Equals method can be used if you want some functionality that the == operator doesn't cover, like case insensetive comparison.
Experience is the sum of all the mistakes you have done.

I am working on ASP.NET application which uses basic authentication.
What I want to achieve is, if a user types a wrong credentials, he should be redirected to a custom error page.
I know that this cannot be achieved using Custom Errors section of ASP.Net as it happens much before that. Something has to be done at IIS level.
But what is to be done, I am not sure…
|
|
|
|
|
Well, now I can redirect the user on providing the wrong credentials…
But the wired thing happening is, the redirected page only renders the static text and not my ASP.Net controls…Grrr

You use the System.IO.Directory.CreateDirectory method or the System.IO.DirectoryInfo.Create method.

Hi
I have a probably quite easy question but which drives me crazy!
I am using a Gridview in my web page. I bind with a sqldatasource and gridview displays all data correctly.
But i want gridview to display an another string instead of the data in database.
For example :
There is a field named "isexists" in my table having 1 or 0 data.
But on the web page , i want to show that column data as "YES" (instead of 1) and "NO" (instead of 0) in gridview.
Could you please help me about this?
Thanks and Regards

Either you can do this in the query or in row_databound event of GridView. In this event check the value, if value is 0 set the cells text as "NO" else "YES".

thankx for your reply.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
but how i check the current value at that record?
i need to know some codes like :
// rowdatabound event
if gridview1.rows(?).cells(??).text = "1" then
gridview1.rows(?).cells(??).text = "YES"
else
gridview1.rows(?).cells(??).text = "NO"
|
|
|
|
|
RowDatabound has two arguments
object and events e
you can go by
e.cells("").value
|

I have been doing similar checks using functions and the Eval keyword... i.e.
...Text='<%# ACunningFunction(Eval("db_field_name")) %>'
Which would require something like:
protected string ACunningFunction(object db_field)
{
}
Are there any performance implications in doing it this way?

|
|
|
|
This is a fair approach and I don't think about any performance issues.

I have a textbox, I want that customer can only read its text but problem arises when text exceeds from the width of the textbox. In normal case we can read all the text by using arrow keys. How can I read text when textbox is read only?
Regards, Qaiser Nadeem

If you are not allowing customer to edit the field, why textbox is used ? Try to use Label/Literal instead.

Text area may be another option

A web application is developed using .Net framework 1.1 , Visual studio 2003, on windows 2003 server. Now application is exported to new machine with both the versions of .Net framework installed on it , i.e 1.1 and 2 ... The machine carries both the development environments, VS 2003 and VS 2005. The error resulting in opening the application is stated as " Web server is not running Asp.net version 1.1. you will be unable to run asp.net web applications or services" .
With the help of MSDN I have gone through almost all the solutions , includiong reinstalling the correct version of asp.net 1.1.4322, setting right version of asp.net in default web site settings, allowing asp.net 1.1 and asp.net 2 versions in web server extension settings .. resulting not a solution .. can anyone help in that .
