Question

I am using Web Browser control in my project and i open a web that have file chooser object.
Now i want to inject programmatically a path to a file in this file chooser object .

I tried to get the HtmlElement ,but i not found in the source code the element Id.

Edit:

In the web there is “Browse…” button that open a file chooser,and then the file path is show in little text filed, and i want to inject the file path my self to the text field.

First.
establish a name, id or class for the element you want to change the value of. There are a number of ways of doing this. I would use firebug for firefox, or IE developer toolbar, or just view the source of the page and establish what the name/Id of the field is. Now if that field does not have a Name or an ID that you can use you might be able to get the containing element and iterate through the Child elements n times until you get the element you want.

For my embedded browser app I did the following in c#:-

// webBrowser is the name of the embedded IE browser in your app
var htmlDocument = webBrowser.Document;
if(htmlDocment!=null)
{
    var field = htmlDocument.GetElementById("...the id...");
    if(field!=null)
    {
        field.SetAttribute("value","...yourfilenamepathonyourmachine...");
    }

    // Now you would need to establish the ID of the submit element and click that
    var submitButton = htmlDocument.GetElementById("...submit button...");
    if(submitButton!=null)
    {
        submitButton.InvokeMember("Click");
    }
   // your code to loop?
}

So do you have the HTML of the page in question? that might help and a better answer can be given
