Abort a downloadfile()

[papiosaur]

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?

dont be so hurry when thiking

see, first there no adaptater (french?) , hurl has only closing ", 3rd argument in DownloadFile ...doe not exist

Code: Select all

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

@plouf: bad adaptation of french langage

Thanks! I correct that

[papiosaur]

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?

I have retested and bizarely i have a new message error now immadiatly when i click on "Abort" button.

Requested object not found!
File: script.hws (current line: 459 - In function: ContinueAsyncOperation)

For my "Abort" button the action is : CancelAsyncOperation(handle)

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

[papiosaur]

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.
