Calling a function from within a function declaration

[d347hm4n]

Hello all,

Just started using AutoIt 3.

Nice little language, the editor is also quite nice.

I'm trying to download a file from behind a button.

I have the following function to create a button:

Func CreateIndividualButton($btnText,$pos1,$pos2,$pos3,$pos4, $toolTipText,$funcToCall)
    GUICtrlCreateButton($btnText, $pos1,$pos2,$pos3,$pos4)
    GUICtrlSetTip(-1, $toolTipText)
    GUICtrlSetOnEvent(-1, $funcToCall) 
EndFunc

As you can see, I'm passing a function to call to the button create function.

This is called like this:

CreateIndividualButton("DTaskManager",30,90,210,30,"Task Manager Alternative",'dtask')

And it works.

Now that I'm tidying up the script I have written a new function which is called like this:

DownloadCheck($appName)

As you can see it is taking a variable.

I thought it would be something like this:

CreateIndividualButton("DTaskManager",30,90,210,30,"Task Manager Alternative",'DownloadCheck("dtask.exe")')

But it doesn't work. Is there something that I'm doing wrong or is this just not possible.

Thanks for any help.

Peace,

What does "DownloadCheck($appName)" return ? Does it return anything?

[d347hm4n]

It has a void return. Just contacts the download server with the name of the application to download. And then downloads it.

It has a void return. Just contacts the download server with the name of the application to download. And then downloads it.

In that case there is no point in using it as a parameter. Instead just add the call to the start of your function.

I think you have misunderstood.

I have a function to create a button, I'm setting the event of the button to be a function.

If I have a function like this:

Func dtask()

local $app = "dtask.exe"
DownloadApp($app)

EndFunc

And I pass it in like this:

CreateIndividualButton("DTaskManager",30,90,210,30,"Task Manager Alternative",'dtask')

It works.

BUT

If I want to pass the name of the app to download directly in the button function.

CreateIndividualButton("DTaskManager",30,90,210,30,"Task Manager Alternative",'DownloadApp("dtask.exe"')

It fails with the folowing error.

script.au3 (148) : ==> Unknown function name.:
GUICtrlSetOnEvent(-1, $funcToCall)

Why do you need to call DownloadApp("dtask.exe") in the other function as param?

Why not call it just before it and then call it like:

DownloadApp("dtask.exe"')
CreateIndividualButton("DTaskManager",30,90,210,30,"Task Manager Alternative")

Thanks for all of the help. I spotted the solution in Martin's Sig.

That allows a function with parameters to be passed to a button during it's creation.
