Hello,
i would like to abort a
DownloadFile() command with a button with ID "abort" but don't find the solution with many tries.
My command line is :
Code: Select all
Downloadfile(entry$, {File = f$, Adapter = "hurl"}, p_SetProgress)
My function p_SetProgress is:
Code: Select all
Function p_SetProgress(msg)
maxi$ = msg.Total
moai.Set("prgbar", "max", maxi$)
moai.Set("prgbar", "level", msg.count)
EndFunction
I see in documentation to add a msg.action in the "func" tion but anything work...
Thanks for your help.

By default
DownloadFile() runs synchronously so you can't abort it because it won't return before it's finished. If you want to be able to abort it, you need to set the "Async" tag to TRUE and then repeatedly call
ContinueAsyncOperation() until it returns TRUE, e.g. something like this:
Code: Select all
handle = DownloadFile("http://example.com/example.zip", {Async = True, File = "example.zip"})
Repeat
done = ContinueAsyncOperation(handle)
...do something...
VWait
Until done = True
In such a setup, you can then call
CancelAsyncOperation() to abort the download.

@Andreas: i wrote this but download don't start...
Code: Select all
handle = DownloadFile(entry$, {Async = True, File = f$, Adaptater = hurl"}, p_SetProgress)
Repeat
done = ContinueAsyncOperation(handle)
VWait
Until done = True
I obtain a Hollywood request with:
File:script.hws (current line : 485 - In function: ContinueAsyncOperation)
An idea please?

Code: Select all
handle = DownloadFile(entry$, {Async = True, File = f$, Adapter = "hurl"})
Repeat
done = ContinueAsyncOperation(handle)
VWait()
Until done = True

Bizarre, my
ContinueAsyncOperation() don't change color in my IDE (FlowStudio)
CancelAsyncOperation() too...
And it's not in french
I have always the same problem with correction...
Maybe not implemented in MorphOS version?

You have to learn to create small snipets to actually track down problems
You are a smart guy, capable for a lot . But taking thinks too "fast and furius"
In order to understand your problem create a
MCVE. Thats the minimun possible code fully executable , that its fully self alone
Then think of the problem line by line, of what wrong happen
If not find paste the
MCVE here to check and get help from rest

Thanks plouf for the smart guy
I hope a little
My big problem, it's very difficult for me to do a minimal code with just only the necessary...
In my project, there is databases, internet access, a listview, many buttons, etc...
I have found the problem i think, it work now.
Sometimes i have errors message and now it's ok, bizarre...
Async mode is more sensible to bug no?
I will post my code for
DownloadFile() and Abort command via button soon after more test and i will add comments.
