Is there a way in Javascript to bring up dialog boxes for both opening and
then also saving a file?

Is there a way in Javascript to bring up dialog boxes for both opening and
then also saving a file?

Please clarify the question.
What file is being opened?
What do you mean by 'dialog box'? A prompt? A window? A "browse" button? A
modal dialog window?

What do you mean by "and then also"? Same button/prompt/whatever does both
tasks? A dialog box for both tasks, but the dialog box is not the same
object?

This is going to be a file compare program. I just need to have the
standard windows open file dialog box open so the user can select the
file, i will use this twice so they can choose the two file's to be
compared. After the compare i want the standard windows save as box to
appear so they can save the results file.

In general, Javascript cannot read or write files from the local
filesystem.

You can create an "open" dialog by creating an <input type="file"> form
element and could probably open it by invoking its onclick method
(though I haven't tried it). But I don't think that the content of the
selected file is available to Javascript (again, I haven't tried).
Similarly a server-side implementation can trigger a "save as" and/or
"open with" dialog by returning content of a type that the browser
cannot handle natively, but I don't believe there is a way for
Javascript to generate such content.

I would be curious to know if anyone can suggest a way of doing this.

I dont plan on having the browser open and doing this in an html page, i
guess i was assuming you could run javascript by itself like vbscript

The file input type prompts for a file on button click.
<input type="file">

For saving the results, I believe this would work. (Windows / MSIE only?)
document.execCo mmand('SaveAs') ;

If this is running on a PC, you may want to look into using an HTA with
Windows Script Host. You don't tend to run into as many security problems
that way. You get more stuff to play with, too. Check out FileSystemObjec t.

You can.. as an HTA application.
HTA gets a lot of bad press because it's an obvious tool for virus
writers, but it effectively allows you to write an HTML application
that lives outside the Browser sandbox. If you're not looking to put
it online, and need a rapid dev environment, it's ideal. I've used it
to produce simple applications before that leverage the easy displaying
power of HTML, to be run from a local pc or over a network. Obviously
all your code is visible, so not recommended for anything that requires
security.

Also, because it's out of the sandbox, you can do all manner of loading
and saving files using the standard FileSystemObjec t (or any other Com
type stuff).

Where can i get information on HTA.

[runonthespot]

Kind of hard to find definitive guides to all it's uses, but
http://msdn.microsoft.com/workshop/a...taoverview.asp
gives you an overview. Basically it's an HTML file, saved as .HTA, run
using MSHTA.exe (in windows path).
Think it only really needs some sort of rudimentary tag in the head
like
<HTA:APPLICATIO N ID="oHTA"
APPLICATIONNAME ="MyApp"

From there just build HTML as usual. I keep my scripts in a seperate

..js file, linked in.

It's sometimes hard to find Javascript syntax for things like
FileSystemObjec t, but the info is out there on the web. Takes some time
to find, and if you are familiar with the VB versions, it doesn't
require much altering.

You could of course write the HTA using VBScript...

I have coded the open dialog in vbscript but couldn't find the save as, as
vbscript is the preferred method for the client.
