Vista - write into an <input type=file> field

03-04-2009

Hello,
There is a page on the web with an input type=file field named "sourcefile".
While I can fill in the other fields in the form, nothing is written using
..document.forms(0).Item("sourcefile").value = "C:\Users\standard\Desktop\fax.doc"
The only way is to use sendkeys.

The fact is that if I manually select a file and then READ the value, it is correctly
retrieved.
msgbox .document.forms(0).item("sourcefile").value
returns the name of the file selected.

I can set the content of the field with a script in a local html file, but it seems not to
work (nothing is written to the field) in a vbs which loads the page and fills the form.

Being able to read the content, I am sure the path to the field is correct.

Thank you for your help.
Giovanni.

Can you build a little HTA that contains the relevant code and demonstrates
how it does or doesn't work, and post it here?

This is the intended behavior of the FILE type of the INPUT element.
Otherwise, permitting a default value to be defined would open a
security hole. That is, a web page author could preload the INPUT
element value with file names and upload them to his/her server
without requiring the client's interaction. Not a good thing.

The use of Sendkeys is the only known way to populate a file type
input box (in a client initiated script application). That's why I
worked to find a way to use drag-and-drop onto IFRAMEs in HTAs. It
greatly simplifies the loading of files.

Thank you very much.
It is important to know there is a reason for this behaviour.

Sure,
it might be of help for those who want to automate interaction with a web site.

WScript.CreateObject("InternetExplorer.Application", "oIE_")
' Setta le proprietà della finestra del browser
oIE.left = 20 ' La finestra
oIE.top = 50 ' in alto a sinistra,
oIE.height = 380 ' piccola...
oIE.width = 580
oIE.menubar = 0 ' Senza menu
oIE.toolbar = 0 ' né barra degli strumenti
oIE.statusbar = 0 ' né barra di stato per essere più riconoscibile.
oIE.navigate("about:blank") ' Crea un documento HTML vuoto.
oIE.visible = 1

homepage="http://corrisp/dsp.asp?pagenumber=1"

oIE.navigate(homepage) 'Richiede la pagina
Do until oIE.readystate = 4 : wscript.sleep 10: Loop

oie.Document.Forms(0).item("nr").Value = "1368223"
oie.Document.Forms(0).item("dt").Value = "2008"
oIE.Document.forms(0).submit

but

oie.document.forms(0).item("file").value ="c:\data.txt"

doesn't fill the field.
