Re: To not save the doc...

Well, in a way I did...


What I do is this:
1. User creates a new doc and can upload up to 5 files.


2. In the WQS event, check if the total file size being submitted is over 10MB.


3. If the total file size is <10MB, then continue to save the doc (set
SaveOptions="1")


4. If the total file size is >=10MB, then do NOT save the doc (set
SaveOptions="0")


5. In my $$Return computed field, I have the following formula:


@If(SaveOptions="0"; "[/" + DbPath+"/FileSizeError?openform"+ "]";
"[/" + DbPath+"/0/"+@Text(@DocumentUniqueID)+"?EditDocument"+ "]")


6. In another computed field (I called it "SetHTTPHeader"), I have the
following formula:


@SetHTTPHeader("Expires"; 0)


Thus if the check returns false (exceeds 10MB total file size), then the doc
will not get saved and the FileSizeError page is returned.
On the FileSizeError page, I have a button "Go Back", with the code:


<a href="javascript: onClick=history.back(-1)">Go Back</a>


Voila! =)


Now, in testing this, it does work.... the only issue I am encountering is the
fact that on the server doc, the setting is set to 10MB, and my check in the
WQS agent checks for 10MB as well. But when I submit a file size greater than
10MB, it returns that ugly "Error 500 " page... which only means that the
server checks the file size of the request being submitted first before the WQS
is done?? Any idea why I'm getting this?
