ovide CodeHi All,
I am developing a C# windows application where I am using windows web browser control to automated a web application. I am using webBrowser1_DocumentCompleted event to download file it is working but at the end it popup windows message box for that I am using timer event with sendKey so download is happening but after that it goes to other pages not in home page.

What should I do Please advice.

Below I provide Code

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
if ((bFirstTime == true) && (e.Url.ToString().Contains(sPageLogin))) //only first time
{
toolStripTextBox1.Text = webBrowser1.Url.ToString();
bFirstTime = false;
HtmlElement heElement;
HtmlDocument doc = webBrowser1.Document;
HtmlElement userName = doc.GetElementById("userName");
HtmlElement password = doc.GetElementById("password");
if (userName != null)
userName.SetAttribute("value", "hello");
if (password != null)
password.SetAttribute("value", "thnaks");
System.Threading.Thread.Sleep(2000);

foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("input"))
{
if (el.Name == "login" && el.OuterHtml.Contains("javascript:doSubmit()"))
{
el.InvokeMember("Click");
System.Threading.Thread.Sleep(2000);
}
}

}
else
{
if ((e.Url.ToString().Contains("/1/roleDefine.do")) || (e.Url.ToString().Contains("/abc/xyz/mno/1/retrieveHomePage.do")))
{ //https://applications.abc.com/xyz/mno/mtnl/1/roleDefine.do
foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("a"))
{
if (el.OuterHtml.Contains("/tdct/prod/wlbx/1/D624D669/en/images/buttons/home_images.jpg"))
{
el.InvokeMember("Click");
}
}

}
}
else if ((e.Url.ToString().Contains("/tdct/prod/wlbx/1/transaction/searchCheck.do")))
{
//httpshttps://applications.abc.com/xyz/mno/mtnl/1/searchCheck.do
foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("a"))
{
if (el.OuterHtml.Contains("/tdct/prod/wlbx/common/images/icons/save.gif"))
{
el.InvokeMember("Click");
}
}
isHasAttachment = true;
if (isHasAttachment)
{
SendKeys.Send("{Enter}");


//System.Threading.Thread.Sleep(5000);

System.Windows.Forms.Timer t = new System.Windows.Forms.Timer();
t.Interval = 15000;
t.Tick += new EventHandler(timer_Tick);
t.Start();
}
}

void timer_Tick(object sender, EventArgs e)
{
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
SendKeys.Send("{TAB}");
SendKeys.Send("{ENTER}");

}
}
Thanks to All
