invalid key to 'next' ???

[phdminh]

Hi there, I want to create a small script to add any file in videos folder at "Autoplay\\Videos\\" to a tree when show with my code:

Debug.ShowWindow(true);
Debug.SetTraceMode(true);
result = File.Find("Autoplay\\Videos\\", "*.*", false, false, nil, nil);
Tree.InsertNode("Items",0,result);
context = Debug.GetEventContext();
Debug.Print(context);

When I run preview, it shows a dialog box show that:

Error: invalid key to 'next'

Stack Traceback:

1: [Page1 -> OnShow] Line 4: in main chunk

Debug show that:

---------------------------
Error
---------------------------
Error: invalid key to 'next'

Stack Traceback:

1: [Page1 -> On Show] Line: 4 in main chunk
---------------------------
OK
---------------------------

I don't know where the error is and how to fix it! Can anyone help me to fix this?

I want to edit but i don't see where can I edit my post.

Debug show like below:

*** LOCATION: Page1 -> On Show
[3]: result = File.Find("Autoplay\\Videos\\", "*.*", false, false, nil, nil);
TRACE: LastError = 0 ("Success.")
[4]: Tree.InsertNode("Items",0,result);

For starters, check the documentation... File.Find() returns a table, where each element contains the path of the file that was found.

The third argument to Tree.InsertNode() is also a table, but using a completely different data structure - its an associative array with 8 fields. So no, you cannot simply use the same variable.

Fix your code first, and if that does not solve the problem, attach the exported project file (*.apz) to your post.

try this code:

Debug.ShowWindow(true);
Debug.SetTraceMode(true);
result = File.Find(_SourceFolder.."\\Autoplay\\Videos\\", "*.*", false, false, nil, nil);
if result ~= nil then
	for i, found in pairs(result) do
		sPath = String.SplitPath(found);
		tblNodeData = {};
		tblNodeData.Text = sPath.Filename;
		tblNodeData.Data = found;
		tblNodeData.Expanded = true;
		tblNodeData.NodeIndex = i;
		Tree.InsertNode("Items", i, tblNodeData);
		context = Debug.GetEventContext();
		Debug.Print(context);
	end
end
