void
TreeView1AfterSelect(object sender
, System
.Windows
.Forms
.TreeViewEventArgs e
)
{
string x
= e
.Node
.Text
;
switch(x
)
{
case"Node1":
webBrowser1.Navigate (@"\s.html"); ////this works fine
webBrowser2.Navigate (@"\x.html"); ///this works fine too
break;
case"Node2":
webBrowser1.Navigate (@"\s.html"); ////this works fine
webBrowser2.Navigate (@"\x.htmlx"); ///i dont have this file becouse i want to create an error !!
i want to catch this error and it must load an empy file of or navigate to ("")
if the file does not exist then dont wat a messagebox with error etc etc...only load an empty file if the file does not exist.visa versa for webbrowser1.navigate(@"\s.html");
break;
}
i can't vigerout how to solf this problem.
