Re: How do you set a time delay for Response.Redirect()

That is a great point. I am not sure why you would want to delay a redirect anyway.

ASP.NET is a framework which generates HTML on the server. Javascript is the language that runs in your browser, and the language in which ASP.NET generates code to do anything that runs on the client ( such as validation ). Buy a javascript book and work through it, or look up some tutorials on the web.

What should i do to prevent it.But there is some session concept. I don't to how to incorporate in my application. I am expecting somebody help in this issue.

There R many ways of doing it.

Method 1: (Using Sessions)
in the page load event of login page

create a session variable like Session["isValid"]="Valid";

In the load event of the other pages,
check if the session variable isValid exists.

i.e.

if( Session["isValid"]==null)

Response.Redirect("Home.aspx");

Method 2: (Using forms authentication)

This is the most reliable one and widely used by the developers.

The Server.Transfer will just continue with execution of the new file, sending output to the same Response object. This means that the url of the page will not change.

A Response.Redirect will create a redirection page that is sent to the browser. The browser will then request the new page from the server.

I have installed on my laptop both:VS2003,VS2005.

When I run any VS 2003 application I got the error:

Error while trying to run project:unable to start debugging on the server.You dont have permission to debug the server.Verify that you are a member of the 'Debugger Users' group on the server.

But I have checked the Computer Management and I found the my account(an administrator account) is on of the mentioned group.

I tried many solutions for many days but it is no use.

I hope that someone could help.

I am too late but i will never give up

Re: Adding target to a button

28-Apr-07 22:09

hello, i used a System.Web.UI.WebControls.HyperLink
(the hyperlink) server control instead of button. It has a target property that u can set to _blank.
how ever i am not sure how to make the hyperlink look like a button.. perhaps by setting its ImageURL property?

As a redirect is done in server code, it's impossible to select a target for it. The target is decided before the request is sent to the server. If you want a different target, you have to set that in the browser before the request is sent to the server.

You can use Javascript in an html button:

<input type="button" onclick="window.open('TheNewPage.aspx', '_blank');" />

how2 add confirmation pop up upon loging out (LoginStatus control)

yet_alive28-Apr-07 19:18

Re: how2 add confirmation pop up upon loging out (LoginStatus control)

28-Apr-07 19:18

Hello every one Smile | :)

i am trying to find a way to add a pop-up confirmation to LoginStatus control when you click Logout.

here is the code i tried.. with no luck of pop up showing up.. Confused | :confused:

i'd appreciate any thoughts/suggestions/corrections!

i have set the "LoggingOut" event of the LoginStatus control to: (userLoggingOut). My loginStatus control is: logStatus

and then tried both of these codes in the code behind.. still i cant see the confirm message pop up! any idea what i might have been doing wrong?

thank u so much in advance Big Grin | :-D

protected void userLoggingOut(object sender, LoginCancelEventArgs e)
{
LoginStatus lgst1 = (LoginStatus)FindControl("logStatus");
lgst1.Attributes.Add("OnLoggingOut", "return confirm('Are you sure')");

}

======>>>> and i tried this too:

protected void userLoggingOut(object sender, LoginCancelEventArgs e)
{

string Msg = "are u sure";

LoginStatus lgst2 = (LoginStatus)FindControl("logStatus");

lgst2.Attributes.Add("onclick", "javascript:return " + " confirm('" + Msg + "') ");

}

Re: how2 add confirmation pop up upon loging out (LoginStatus control)

29-Apr-07 2:07

You have the right concept, but you are trying to add the javascript too late. YOu need to add the javascript to the logout button on the page load and it should be on the onClick event. That way the java script will be in the page when the user clicks the button to log out.

Hope that helps.

OMG i thank u soOoOoO Big Grin | :-D

much!! it worked at last!! this indeed was the problem!! i was searching for God knows for how many days!
may i ask you kindly to shed some light on the Add Attribute. i was trying (failed) to find.. how come we could Add an Attribute "onClick" to the loginStatus control.. although it doesnt have this as an Event in its list of events?

thank u so much for any info u might share Smile | :)

kubben29-Apr-07 3:36

Re: how2 add confirmation pop up upon loging out (LoginStatus control)

29-Apr-07 3:36

What you are seeing for the events are the asp.net events. When the web server sends html to the web browser all of the asp.net controls get translated to html controls. The html control has the onClick event. Javascript is always dealing with the html controls and their events, not the asp.net controls and their events.

Hope that helps.

Error in Process.Start

Arun.Immanuel28-Apr-07 17:10

Re: Error in Process.Start

28-Apr-07 17:10

Hi,

In my web application, I am executing an exe file using process.Start

I have 2 exe files in a directory.
1.First exe file is a stand alone one.
2.Second exe file will refer to another file(file2.ctf) in the same directory.

If I try to execute the first file, it is working fine.
But, for the second file , it says error message like:

Make sure the directory containing file2.ctf is on your dynamic load library
path(PATH on Windows,or LD_LIBRARY_PATH on Linux).

I think the exe file is not able to find the file2.ctr file.
Even after changing the environment variable PATH , it is throwing the same message.

But it is working fine in WindowsApplication.

Any help would be appreciated.

Regards,
Arun Kumar.A

kubben29-Apr-07 2:11

Re: Error in Process.Start

29-Apr-07 2:11

You might need to change some info in your StartInfo object that is associated with the Process object. There is a property called WorkingDirectory off the StartInfo object. Set that to the correct directory and it should work.

Hope that helps.
