Update Data without refreshing whole browser

sebastian

Hey :)

I'm pretty new to C#, but I decided to start a little project to understand the way of C#!

So, I want to get some data from the html file of a webpage. I'm currently doing that with the following method:

 private string[] GetRessources()
        {
            string[] ressources = new string[3];
            
                ressources[0] = browser.Document.GetElementById("res1").InnerHtml.;
                ressources[1] = browser.Document.GetElementById("res2").InnerHtml;
                ressources[2] = browser.Document.GetElementById("res3").InnerHtml;
            
            return ressources;
        }

after running the method, I'm actually getting those ressources!
But on the real webpage, the ressources are refreshing every second. In my program they aren't!
Can I somehow repeat the method every second? I've tried to put the code lines 5-7 in an endless while-loop, but that causes my program to "not response", logically ^^.

If you told me any method to check for a change and update those ressources if there were, without letting the program cash, i'd be very thankfull! I'm having this problem with some other methods, too.

thanks! Basti

Crish,

Why you posting such replies. Its in php, this is an C# Corner forum.

Just check the syntaxes and its same, just take a timer control and write in the timer tick event, make sure you set enabled property to true...

A big thanks to both of you!

@ santhosh: Can i use the timer just like you did? without implementing or "using" anything? I'll also check this out when i'm at home!

@ crish: Sorry, but I don't understand your code :|
In general: what does it do? I only understood that it does only work if the send-method is "post" - if the server uses this method ...

Hi

You can refer below code to solve the issue of update data without refreshing whole browser.

php

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // insert the data here
    header('Location: /createdClass.php');
    exit();
}

?>

php echo $_SERVER['PHP_SELF']; ?>" method="post">
...


I think it will help you.

If this is windows app, you could put them in a seperate thread or timer and do those for every interval of seconds

timer1_tick
{
string[] ressources = new string[3];

ressources[0] = browser.Document.GetElementById("res1").InnerHtml.;
ressources[1] = browser.Document.GetElementById("res2").InnerHtml;
ressources[2] = browser.Document.GetElementById("res3").InnerHtml;

return ressources;

}
If its web app, you could use setTimeOut function to call the function recursively after configured milliseconds
setTimeOut(functionName, 100);
