Hello All,

We have a scenario for exporting some data to Excel when the user clicks on Export to Excel button. We have "Export to Excel" button on Master page. Anybody has idea to stop page postback on Export button click?

Can you please shed some light on this?

Thank you in advance,
Raheem MA

You can set the following property of your asp button:

OnClientClick="return false;"

Example:

<asp:Button ID="btnID" runat="server" Text="ButtonLabel" OnClientClick="return false;" />

Hi..
I have an issue with the User table..How can I prevent a user deleting himself?
I am giving the procedure below:

ALTER PROCEDURE [dbo].[Usp_User_Delete]
@LoginID AS int,
@DeletingPersonLoginId AS int,
@ErrorMessage as varchar(100) OUTPUT
AS
BEGIN
SET @ErrorMessage = 'SUCCESS'

	BEGIN TRY
		DELETE FROM [tbl_User]
		WHERE
			
		ID = @LoginID and ID<>@DeletingPersonLoginId
	END TRY
	BEGIN CATCH
		SELECT @ErrorMessage = ERROR_MESSAGE()
	END CATCH

What I have to check in C# code before delete command firing???

If you don't want the user to be able to delete themselves why offer the ability to do so?

As digi man said, don't allow the option. You should have some idea which user is executing the command, you can tell if they are admin or not, so just don't allow that user ID to be used, or don't show it in your list.

Hello All,

I am New in ASP.Net But currently I am working on Desktop Applications. Now i have decided to Design Web Application. I want to develop a Music Web site using ASP.Net and SQL Server as back End. In this Scenario I have a single problem that,

if I have uploaded some audio and video files on a server (not my domain that is rapid share or megaupload) then is it possible in ASP.Net to Play them or download them without leaving focus from my web page.

Because i have already uploaded files on sharing server and this time i have less space on my domain.

Thanks in Advance.

Yes. You can use AJAX for that. I'd prefer the raw AJAX. Use javascript to open your async connection with the server with XmlHttp or Activex object (for IE). Set your target as another aspx page or PHP page. Do all your processing in that page. Generate a response and then use responseText to retrieve it in ur page. No need to refresh at all..

IIS worker process NT user-id [modified]

I'm trying to get definitive information about the OS account ID used by the IIS process(es) on server OSs.

We have a product install that must allow modify access to a registry key we create.

Right now, we have found that the user-id IIS_USRS should be used for a Server 2008 R2 box with IIS 7.

But I have no idea if this is all we need to do for an Server OS and other versions of IIS, e.g. IIS6.

I also read about IIS 7 and its support for app pool identity accounts, for example w3wp.exe runs under 'DefaultAppPool' but this isn't a 'real' user id and cannot be specified for setting either file or registry access control.

The situation is that our product is a class library that may be used by web services or web apps, the library requires modify access to a special registry key (specific to our product) and hence this question.

Should I simply allow mod access to IIS_USRS or NETWORKSERVICE or what?

Does a web app/service always run within a process named w3wp.exe?

Any info much appreciated.

Harry.

Hi Guys and Gals,

I'm having an issue with creating and using an email form in ASP.Net. I cannot use SMTP and thus far have been unable to come up with something else useful. Any suggestions or resources I should check out? Thanks for all you help.

Parameters after '&' is considered as a Query String. Thus, in order to use it in a vald complete URL you need to encode your URL. As Mark suggested, URL.Encode would do this for you.

Encoding will convert this ampersand into it's html equivalent and thus will not make part of the text after it as query string.
