Hi,
How can i randomly generate a number every (for example) 20 minutes with php?
I know how to generate a number, but i have no idea how to make it generate one every X minutes.
Thanks in advance!

This may sound like an obvious answer but you just put your random number generator in a loop, and include whatever PHP command is required to sleep for 20 minutes each time around the loop.

I dont want the app to sleep. It has several other things to do.
Got another suggestion?
|
|
|
|
|
Sorry no, I guess you have to find some way of checking the time every so often and after twenty minutes call your generator function.
|
|
|
|

I suggest you take the initial idea and find a way to create another process to do the other tasks that need to be done...I other words, you'll perform the update the time and sleep for 20 mins on one process thread and on the other thread you'd perform the remaining tasks.
Hope this helps.

May I suggest you spend time in "read only" mode until you are more familiar with how the forums operate, before starting to answer queries. That is, unless you absolutely have the solution to a poster's question.

I may be a tad late to the game here but if you are using Linux or Mac this should work fine for your needs.

<code>
$random_number = rand(); // I will let you worry about seeds and stuff, perhaps call your own make_random() function?
print('Random number is '.$random_number."\n");
declare(ticks = 1); // Set ticks to one second
pcntl_signal(SIGALRM, "signal_handler"); // Installs a signal handler for SIGALARM (works in linux/mac only I think)
pcntl_alarm(1200); //trigger alarm in 20 min (60 seconds * 20 min = 1200 seconds)
// This is just to keep the script running forever, I would HOPE you would have real code in here rather then just looping endlessly.
for(;;)
{
sleep(1);
}
function signal_handler($signal)
{
global $random_number;
switch($signal)
{
case SIGALRM:
$random_number = rand(); // New random number, I will let you worry about seeds and stuff, perhaps call your own make_random() function?
print('New random number is '.$random_number."\n");
pcntl_alarm(1200); //trigger alarm again in 20 min
break; // Exit function and continue normal code execution.
}
}

Good Morning,
I am trying to write a simple time out javascript to accompany an ASP.net application. The default time out for the application is 20 minutes. Currently, when it does time out, it reverts to an ugly error page. I would rather that it either logs the user off or simply sends him to the login or index page. Although I have found some very seemingly simple samples, I cannot get anything to work. I do not know if it makes a difference, but I am using an internal (<Iframe>) to rotate pages within a main page. I do not why that should make a difference since the session value is based on the session and not the page. Either way, I have tried posting the script on both the Main page that displays the frame and on the inserted frame page as well. It makes no difference. These are the two scripts that I have tried:
Style 1 is supposed to give the option to take the user to a new page if it is not responded to:
function warnuser()
{
if (confirm("There has been no activity for some time.\nClick 'OK' if you " +
"wish to continue your session,\nor click 'Cancel' to log out.\nFor your " +
"security if you are unable to respond to this message\nwithin 2 minutes you " +
"will be logged out automatically."))
{
//post the page to itself
document.location.href = "Main.aspx"
}
else
{
document.location.href = "Index.aspx"
}
}
Style 2 is simpler and simply posts a warning:
function SessionAlert()
{
alert("Your Session will time out in 19 minutes");
}
setTimeOut("SessionAlert", 1 * 60 * 1000);
I tried setting the second one for just a minute just to see if it would work. It doesn't. Following is the setting that is deployed on the web.config page in the ASP.net applcation (and it does time out in 20 minutes):
<sessionState mode="InProc" cookieless="false" timeout="20" />
Any assistance is greatly appreciated....Pat

The following javascript will simply run in background and redirect the user whereever you want - (The '3000' value is in milliseconds.)
var t=setTimeout("document.location.href ='somewhereelse.aspx'",3000);
Note this method is client side and works on the users browser. Clients can sometimes turn off javascript.. server side maybe needed.
I won't go into the server side options here - too many! This codeproject article however is excellent for giving you a through introduction:
Beginners Introduction to State Management Techniques in ASP.NET[^]
I think where you're having problems is the iframe though. Your time condition needs to sit on either one or the other. In your case I would suggest the main page - the parent page to the iframe. Set a timer - client or server side here and the child iframe will have to inherit the command.

Hi,
In ASP.NET code, in Global.asax.vb file, Sub Session_start add the following lines:
If User.Identity.IsAuthenticated Then
Session("username") = User.Identity.Name
End If
Session("username") will keep the windows username in the session.
Rgds,
Saša

you can always get the current user details from the context object. No point storing them in a session variable.
As for passing the user name to the web app, how do you thing windows authentication works? It does it for you.

Have you tried asking Yahoo? I would seem logical.

Have you tried google for "web site hosting" - there are millions of hits.

Hi,
I cannot use any of the features (like intellinsense, auto tag creation, scripting, outline tags, switching between design and code) in my visual studio html pages (like .aspx, .ascx, .html ,etc.,.) in 2008. But in visual studio 2005 its perfect. I use svn (subversion) as my source control and am not sure that causes any issue. In short, i can open the page and work like notepad in visual studio)
P.N: when i select tools=>options=>html designer, it shows An error occured loading this property page.
For a better understanding, check out the url below a clear picture of my issue (since asp.net forum doesnot have the feature for picture uploading i am using another link for bringing out my issue.)
