Take items from a Collection and write them to a XML Document [modified] Psycho-*Coder*-Extreme29-Apr-07 5:03 Psycho-*Coder*-Extreme 29-Apr-07 5:03  Heres what I'm trying to do. In my "Extranet" Application I'm working on when a user logs in it hits the database and populates a Collection with the information I want to use about the user throughout their visit (and beyond). Instead of hitting the database each time I want a piece of the information I would like to take that Collection and write it to an XML document for retrieval later, is there a way to do this? I'm not finding many examples of this.

Ben Re: How do you set a time delay for Response.Redirect() Guffa29-Apr-07 6:54 Guffa 29-Apr-07 6:54  You should try to do the delay in the browser instead of on the server. As long as the request is blocked on the server, it will not answer to any other request from the browser. The Javascript window.setTimeout method can be used to run code after a delay. --- single minded; short sighted; long gone; Re: How do you set a time delay for Response.Redirect() kubben29-Apr-07 11:13 kubben 29-Apr-07 11:13  That is a great point. I am not sure why you would want to delay a redirect anyway.

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. Thank You very much in advance. V.Rajagopalan: Re: Navigating one page to another page Arun.Immanuel28-Apr-07 23:36 Arun.Immanuel 28-Apr-07 23:36  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.

Re: Redirect vs Transfer Guffa29-Apr-07 0:45 Guffa 29-Apr-07 0:45  atarikg wrote: umm what is the difference between server.transfer and response.redirect 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. --- single minded; short sighted; long gone; VS2003 VS2005 debugging errors TheEagle28-Apr-07 22:54 TheEagle 28-Apr-07 22:54  I have installed on my laptop both:VS2003,VS2005.

Re: Adding target to a button yet_alive28-Apr-07 22:09 yet_alive 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? HTH full many flowers blush unseen! Re: Adding target to a button Guffa29-Apr-07 0:52 Guffa 29-Apr-07 0:52  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');" /> --- single minded; short sighted; long gone; how2 add confirmation pop up upon loging out (LoginStatus control) yet_alive28-Apr-07 19:18 yet_alive 28-Apr-07 19:18  Hello every one 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.. 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 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 + "') "); } full many flowers blush unseen! Re: how2 add confirmation pop up upon loging out (LoginStatus control) kubben29-Apr-07 2:07 kubben 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.

Re: how2 add confirmation pop up upon loging out (LoginStatus control) kubben29-Apr-07 3:36 kubben 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 Arun.Immanuel 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 Re: Error in Process.Start kubben29-Apr-07 2:11 kubben 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. Ben Re: Error in Process.Start Arun.Immanuel29-Apr-07 2:30 Arun.Immanuel 29-Apr-07 2:30  Thank U very much. I will try and let U know.
