IE8 causing FILE input entry to be blank via SendKeys

Question

Application: HTA (therefore IE) This is an application that uses SendKeys to populate a FILE input field.

Issue: File is never uploaded.

Description: An offscreen form (invisible to user) uploads a file to the server. The file input is entered via SendKeys (javascript). Appears to be isolated to when IE8 is installed.

---

Does anyone know of what may be causing this and any workarounds?

Sorry for lack of information. I will edit the question with additional information if no answers are submitted.

Answer 1

Is it possible to use compatibility mode in IE8 as a work-around?

Answer 2

IE8 has set the <input type="file"> element to read-only in order to prevent security attacks. (see article).

Therefore a programmatic way isn't possible.

Answer 3

the same problem with me i need something to set the value of input type="file"
