You'll have to implement your own file browsing feature then because INPUT
TYPE="File" can't be modified in the way you are asking about.

Add a onkeydown attribute and blur()

<input onkeydown="javascript:this.form.file1.blur();" type="file"
name="file1">

i'm afraid that won't work correctly because the selected file will still
post once it is selected.

That's true, but what the original post wanted was, he didn't want the user
to be able to type in a filename in the text box.

This essentially keeps the user from using the control at all (even the
button, which we want to be able to use).

Not true, we're using it right now with no problems. Can you send me your
HTML code on how you implemented this.
This is working for IE and FireFox on Windows and IE, FireFox and Safari on
the Mac.

onkeydown is for pressing any key and has nothing to do with the mouse.
When you click on the button you're using the mouse, not a key. Unless you
tab over and press the space bar which will click the button.

I jump the gun here, Safari on the MAC doesn't display a text box to type a
file name, it only has a button to select the file.

I havn't tried it, but I think you could create a control that inherits
from the File upload class and override the HTML render method. In your
override you just leave out the textbox.

Anyone tried that?

All the server code does is send over HTML tags, <br>, <hr>, <input>, etc...
to the client browser.
It's the browser that decides what to do with those tags.
In the case of Safari on the Mac, when it sees a <input> tag with a type of
"file", it doesn't display a text box at all only a select button.
IE and FireFox does display the text box along with a button to select a
file.
