Web Browser File Upload Problem

Hi all,

Situation: I have created a very simple .php page which contains:

PHP Code:

---

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="100000" />
Choose a file to upload:
<input type="file" name="uploadedfile" value="" /><br />
<input type="submit" value="Upload File" />
</form> 


---

Now in my program I want to be able to simply click a button and have it fill in the 'uploadedfile' value to a predetermined file path.
This I thought would be easily done using:

Code:

---

    Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
            WebBrowser1.Document.Forms.Item(0).GetElementsByTagName("INPUT").Item(1).InnerText=sFilePath

    End Sub

---

However while this code will work on any other type of html element it won't on this one, due to what I'm almost certain is the fact that the type="file" not type="text" or whatever else.

So, I need a way for my program to put a string of text into a 'filebox' (instead of a textbox).

Cheers
