Hi all,
I have master page. In that i placed a LinkButton(Log Out).
If user clicks on this logout button, i am entering the login & logout information into database and i am deleting temporary folders.
Probem : When user closes Browser window by Closebutton(X), i need to enter the logout information into database & i need to delete temporary folders and files.
I tried the following logic which is suggested by Abhijit Jana.
But its not working.
if any where i went wrong, let me know.
Here is my code

did you call UpdateDataBase this method ever ??  
then how the things will go right ??? just call the function from body unload
<body onunload="UpdateDataBase ()"><br />
<form><br />
.............<br />
</form></body>

Thanks Abhijit, thanks for reply.
I called UpdateDataBse() in MasterPage on Unload event from code behind not from designing.
Default.master.cs:
==================
protected void Main_Unload(object sender, EventArgs e)
{
string str = "<script language='javascript'>";
str += "UpdateDataBase();";
str += "</script>";
Page.RegisterStartupScript("test", str);
}
Ok i will try as u told, Calling method from MasterPage design itself.
I will tell u the result.
|
|
|
|
|
I tried as u told.
<body önunload="UpdateDataBase ()">
<form>
.............
</form></body>
It is not working...
|
|
|
|
|
did you dubug the code?
does Function calling ? give one breakpoint on PageLoad of UpdateDatabase methods check what going wrong.
|
|
|
|
|
Yes i debug the application.
As u told, i called the javascript function in . But how can i place break point to javascript method. Its not allowing. I can put PageLoad but how can trace that javascript method.
I tried Master page Unload event. Calling that method from this event.
When i put break pont here. The statement were executing but nothing is happening. When user closes the browser i cant see this breakpoint.
|
|
|
|
|
I placed that method into script.js file.
I placed a break point on that method.
Its running when user closes the browser.
But the problem is when browser is closed, the value of 'Y' is -ve & 'X' is +ve.
So i modified the condition.
function UpdateDataBase()
{ // Check Browser Close [X] , Alt+F4 , File -> Close
if (window.event.clientX < 0 || window.event.clientY < 0)
{
window.open("DummyPage.aspx?test=test", "OpenWindow_Close_Session", 'left=12000,top=1200,width=10,height=1');
}
}
But even, the 'if' condition is true the control not going into the if block. Its coming out from function(like that condition fails).
I am bit surprized by looking this.
Why the control is not going inside 'if' block.
any help is appreciated,
thanks in advance.
cheers,
sekhar

i am talking about break point on your dummy page. check the value if clientX and ClientY by the alert message.
if you want to debug javascript
use debugger;

Thanks Abhijit, thanks for ur feedbacks.
I placed alert() instead of window.open().
I could see the alert message, when user closes the browser.
But when i replace alert() with window.open() nothing was done.
function UpdateDataBase()
{ // Check Browser Close [X] , Alt+F4 , File -> Close
if (window.event.clientX < 0 || window.event.clientY < 0)
{
alert("Are you sure want to close window?"); // Its working
//window.open("DummyPage.aspx?test=test", "OpenWindow_Close_Session", 'left=12000,top=1200,width=10,height=1'); //Its not working
}
}
In PageLoad event of DummyPage.aspx i just trying to create folder to test the window.open() function. But nothing is created even the condition is true.
Is there any mistake in that method ? It wont giving any errors at runtime.
any help is appreciated.
Thanks in advance.
Cheers,
sekhar

do you have this page in your application ? if yes where it is ?
try to open it form server side check its open or not. then go for window.open().
chenge left, top position to 100,100 , check you are seeing the window or not.
check browser settings for popup blocker !!!!
|
|
|
|
|
Thanks Abhijit, thanks for your kind of response.
Yes i have that page in my application it self.
It's opening through Response.Redirect method.
I will ckeck it out win.open by changing left,top positions as u told.
Cheers,
sekhar.

Thanks abhijit.
I have taken a new sample application to test the above functionality.
I used Ajax ScriptManager control to my page.In that i included Sript path.
I could see the PopUp window. One more issue is, previously the popups were blocked. I changed the internet options.
One more thing which i observed is
we can call server side Page methods from javascript using ajax ScriptManager that also works perfectly. In my openion its better than win.open() method, because we can't change internet options for client systems.
One thing is the PageMethod should be Static and should be WebMethod.
We can do any thing we want. like updating & saving database, deleting files & folders with out changing internet options.
any way abhijit. Thanks for ur suggestions. By ur suggestions i leant new things, thankq so much for that. I solved one of my problem.
Now i have to concentrate on how handle browser <- button after user logouts from site.
Cheers,
sekhar

Hi all,
I wants not allow user to revisit the previous pages once he logged out.
I am using master page, in that i placed a logout linkbutton.
When user clicks on logout button, i am redirecting user to loginpage.aspx.
In the Design of loginpage.aspx i wrote the following javascript to prevent user to navigate through browser -> & <- buttons.
LoginPage.aspx:
<%@ Page Language="C#" MasterPageFile="~/ProxyAds.master" AutoEventWireup="true"
CodeFile="LoginPage.aspx.cs" Inherits="LoginPage" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="server">
<script language="javascript" type= "text/javascript">
if (window.history) {
window.history.forward(1);
}
</script>
<div id="home">
//Login Controls here....
</div>
</asp:Content>
.........................
But its not working.
any thing i am doing wrong ?
please suggest me.
thanks in advance.

I am not calling this in any event.
I placed in LoginPage.aspx design it self, I not placed Javascript in any mehod. I am just checking the condition.
if(window.history) // This will be executed when ever user hits on <-(browser button).
{
window.history.forward(1);
}
I tried the same logic im masterpage, by placing this code in Default.master(in page designing).
Its worked fine. but the probem is it is totally disabling( i mean when user hits <- button he will be there in same page) throughout the application.
But i wants this should only apply after user logouts and tries to hit <- button.(He should see the same page.)

How can I publish to server? Which files are needed to transfer?
If I copy here also like that, Its giving error.
Configuration Error

From Visual Studio -> Right Click on your web folder - > Click on publish.
Then inside your application there would be a Precompiled Folder, inside that your published folder will be there.
Then just Copy that Folder to intetpub - > wwwroot
Go to IIS -> Convert it to Virtual Direcotry and set the settings and run.
if your deploying IIS7.0 then you can check on my article
Read My Latest Article : IIS 7.0 and Deploying Asp.Net WebSites on IIS 7.0

HI Thanks for reply,
