How to do two processes at the same time????

shyam kumar

hello folks,

i have a small issue while developing a windows application using VB.Net . i will explain the scenario here.

My application contains one form which has two tab buttons. say tab1 and tab2. In tab1, i have an option to download data from various sites. this takes few minutes. lets say 15 minutes. and in tab2 i have an option to view the logs.

my problem is i am unable to click the tab2 unless and untill the downloading finish. my doubt is how to do more than processes at the same time. if i am right we need to use threading concept here. but i have no clue how to implement it.

so guys i am expecting wise advice from ur side.

i will give you more idea if u r not clear with my problem

thanks in advance

shyam

be sure to Import

using System.Threading;

        Thread t1;
        
        public Form1()
        {
            InitializeComponent();
        }

        private void DownloadButton1_Click(object sender, EventArgs e)
        {
            if (t1.ThreadState == ThreadState.Aborted)
            {
                t1 = new Thread(DownloadMethod);
                t1.Start();
            }

        }

        public void DownloadMethod()
        {
            // Method For Downloading Content


            //AfterCompleting Download Call

            t1.Abort();
        }

Now your Download Method Will run in Separate Process and Normal Processing will run in Another Process .

Thats it :)

Happy Coding :)

make a separate method for downloading data and Run that method using new Thread

Create new Thread for Executing that method this will not Freeze other tab

or

One another solution to your problem

Download your file With DownloadFileAsync()
Method of WebClient Object This Will not Freez up your tab

private void Form1_Load(object sender, EventArgs e) { WebClient wc = new WebClient(); wc.DownloadFileAsync("url","filename"); }

Happy Coding :)
