In a Try Catch block you can re- throw an exception so that it gets caught again later in the code. You can also use throw inside the try so that you go to the catch logic. The syntax is:
throw new Exception...
Hope that helps.

You need to pass a return URL on the query string when you go to the login page, then use that to redirect back

Hi
I have a normal string-variable in asp.net/c#, that contains cr/nl characters that I want to replace with <br> tags. When viewing the string in debugmode in VS2005, I can see them in there as "\r\n".
I have tried replacing with:
str.Replace("\r\n","<br>");
str.Replace(Environment.Newline,"<br>");
but it does not work. How can I do that?
Wonder if its something about UniCode-characters.
Thanks.

This should work fine. You should put a closing tag in your breaks, so they are XHTML.
What happens when you try this ?

Are you just calling them like this?
str.Replace("\r\n","<br>");
str.Replace(Environment.Newline,"<br>");
Or are you actually assigning the value back to str?
str = str.Replace("\r\n","<br>");
str = str.Replace(Environment.Newline,"<br>");

Use the AddDays function on the datetime to get the next day, and a while loop to loop until the value is a particular date.

Hi All,
i am having some problems with reading data from an excel file (.xls) using my web application built using ASP .Net 1.0 (C#) . it works fine in windows XP (IIS 5.1). but when hosted in windows 2003 server (IIS 6.0) i am getting errors like "Could not find installable ISAM" , "Unspecified Error" etc. i am using C# OLEDB connection to establish a link with the excel file. i have tried almost all formats of connection strings. but the error occurs when Open() method of oledb connection is called.
some of the connection strings i used are :
"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data Source=" + excelFileName +"; Jet OLEDB:Engine Type=5;"+
"Extended Properties=\"Excel 5.0;HDR=Yes;ReadOnly=true \"";
-------------------------------------------------------------------------------------
"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data Source=" + excelFileName +";"+
"Extended Properties=" + (char)34 + "Excel 1.0;HDR=Yes;ReadOnly=true " + (char)34;
--------------------------------------------------------------------------------------
"Provider=Microsoft.Jet.OLEDB.4.0;" + @"Data Source=" + excelFileName + ";" + " Extended Properties=Excel 12.0;HDR=Yes; ReadOnly=true ";
------------------------------------------------------------------------------------------
"Provider=Microsoft.Jet.OLEDB.4.0;data source=" + excelFileName + ";" + " Extended Properties=\"Excel 2.0;HDR=Yes;ReadOnly=true \"";
----------------------------------------------------------------------------------------------
"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data Source=" + excelFileName +"; Jet OLEDB:Engine Type=5;"+
"Extended Properties=\"Excel 10.0;HDR=Yes;IMEX=1;ReadOnly= true \"";
----------------------------------------------------------------------------------------------
please help me to identify the cause of this error and a solution..
Thanks in advance

Why did you create a new account and ask this twice ?
Your code doesn't work. You create an integer and assign a string to it. VB.NET, being crap, will probably turn your int into a string, but you'd do well not to rely on your language of choice being rubbish.
Your code doesn't do anything sensible, but you can assign a variable value to the src property in your code behind, I don't see the issue. Of course, it needs to be a server control.

Passing string value to integer value ? How this is possible ?
I am not sure that I understood your problem, are you trying to assign variable value to src of image tag ? That could be something like
<image src=<%=i%>

|

:-DUse string type variable and assign it to image control property (it means take i as a string type varible)

I've run into a bug that I thought I bring it up here.
I created a simple website and I tried to build it and got the following error:
"Unrecognized attribute 'xmlns'. Note that attribute names are case-sensitive. C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config\web.config 68"
I looked at the web.config file in the project and such line didn't exist.
Next I went to VS2005 and build a simple website, tried to build got the same error.
Then I realize, they are both looking at the same web.config, which is located in
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG
Even though in VS2008 I had selected .Net 3.5, it went and changed the web.config in the 2.0 section.
Any ideas?
Thanks!
