How do I assure/be certain/check in ASP that an html element was fully loaded in the client side?

Hi All,

Hi All,

(this is not the same topic as the my previous topic)


What objects/methods/properties does VBScript offer for:
Assuring/guarantee/make certain that ASP/VBSCript an ELEMENT - e.g.
<img ... /> - was FULLY Loaded into web Browser



My Question is:


describe,

i have a page that does this
a dll thatt does that

the problem temp file


How do I assure in ASP that an html element was fully loaded in the
client side?

myGetImage.asp uses a myGetImg.dll that does the following steps:

1. myGetImg.dll gets a data base record field
2. myGetImg.dll creates a temporary image - out of step 1 - on the
client side - eg. myTempImg.jpg
3. myGetImage.asp has the <img .../> tag, and displays myTempImg.jpg on
the client side.
4. myGetImage.asp uses a simple for...next loop for delaying - because
in step 6 myTempImg.jpg is deleted -
and Server.ScriptTimeout has a bigger value than the default.
5. myTempImg.jpg is supposed to be shown/displayed on the client side
6. myGetImg.dll deletes the myTempImg.jpg


i'm not complete with step 4: that uses for...next loop for delaying,
because it can very annoying
on the client side to wait so long, for a image to be displayed on the
client browser.

My problem is:
On some case - eg where myTempImg.jpg has big size - the
myTempImg.jpg is deleted by myGetImg.dll,
before myTempImg.jpg was displayed on the client/web browser.
the for..next/and Server.ScriptTimeout don't seem as a good idea,
because they sometimes they work and sometimes not.
i've test my page on intranet and it's ok, but i'm not sure this will
be valid for internet testing.



My Question is:

is there any object/way/method in asp, that can
assure/verify/check/make certain that
myTempImg.jpg was fully/100% loaded into the client web server, before
myGetImg.dll deletes it.

OR

How do I assure/be certain/check in ASP that an html element was fully
loaded in the client side?

if its a IMG, use image readystate

Hi Slim,
is there a vbscript version - the sample you gave is in javascript?

Do not for one second think you are creating files on the client. You are
not. You are creating files on your server to be sent to the client as part
of the http response.

3. myGetImage.asp has the <img .../> tag, and displays myTempImg.jpg on
the client side.
4. myGetImage.asp uses a simple for...next loop for delaying - because
in step 6 myTempImg.jpg is deleted -

5. myTempImg.jpg is supposed to be shown/displayed on the client side
6. myGetImg.dll deletes the myTempImg.jpg

All you need to do is ensure that the image file was sent completely. It is
irrelevant how long it takes the client to display it. Set
Response.Buffer=True, then Response.Flush after step 2. Your for... next
loop in step 4 is horribly CPU intensive and can be done away with.

the same.

sub dFish_onreadystatechange
rsc.innerText = dFish.readyState
end sub

ok, slim, thanks for the guidlines - it sure made some order, in the
mess my code was.
