Given an ITEMID_CHILD (ITEMIDLIST) obtained from an IEnumIDList::Next() which is an enumeration of IFolderView::Items(), how do you convert the ITEMIDLIST to the index which would be needed in something like IFolderView::SelectItem()?
P.S. I know IFolderView::SelectAndPositionItems() exists, but this question is specific to obtaining the index (I couldn't find where an ::IndexOf() exists)
TIA!!
There is no direct way exposed by IFolderView to get the index of a given child ITEMIDLIST. You have to remember the index manually while enumerating the folder's items with IEnumIDList. Or, you can loop through the items using IFolderView::Item() until you find an index that returns a matching ITEMIDLIST.
One workaround is to use IShellFolderView::UpdateObject, passing in the pidl as the first two arguments. IShellFolderView::RefreshObject also looked like an option, but for me it returns E_NOTIMPL.

In my problem I search for elements that have an example structure like:
<ngc-product-card ng-reflect-signup-type="comprehensive">
Since the elements may have the comprehensive value stored in another attribute, say:
<new-ngc-product-card data-label="comprehensive signup">
hence I would like to use a wildcard-attribute-name search and also apply the contains() function like:
//*[contains(#*,"comprehensive")]
which doesn't work
What does work is
//*[#*="comprehensive"]
Is there any way to use both '#*' and 'contains()' ?
This should do.
//*[#*[contains(., "comprehensive")]]
Currently, when I use app.Tap I have to give it the exact string.
I want to do something like app.Tap("sstring") and still match elements marked with e.g. "somessting", "someSStRing", etc.
is it possible to have that somehow? it sounds like a simply thing, but I couldn't find a way to do it and it's surprising that there is no option to make it behave that way.
Have you tried doing it via the function overload and specifying the id?
app.Tap(e => e.Id("sstring"));
Marked searches many properties on each element to return any matches.
I have a TinyDB and in each tag of the TinyDB I have a list.
Each list has 3 items, each indexed as 1, 2 and 3.
I want to change the 3rd item, index 3.
So I have done the following
So I want to now save the change in the TinyDB
and have added a storeValue command as follows.
I figured out how to get the valuetoStore variable. As follows.
I had done this before, and thought it wrong because it still doesn't change the 3rd item in the list. But I've added a notifier to look at it and it's correct. So the "replace list item" isn't working how I thought it should. It isn't replacing the 3rd item with an "n."
Any ideas?
Thanks.
Your second try is almost correct. The only thing is, you should use the replace list item block together with the local variable name instead of retrieving the value again from TinyDB.
So what is the difference to your "solution"? Currently you assign the list to a local variable name. Then you use the replace list item block together with a list, you can't store somewhere (you are loading the list again from TinyDB). And in the end you store variable name (which doesn't have been modified at all) in TinyDB. Therefore the solution is to use the replace list item block together with the local variable name instead of retrieving the value again from TinyDB. Btw. a better name for the local variable name would be list.
Further tips
Also in the definition of the local variable name you should add a block, e.g. an empty string or 0
And if you want simplify a little bit, you can move the definition of the local variable name inside the for each loop. And alternatively of using the for each number loop, for list it's easier to use the for each item in list loop, see also the documentation. The list in your case is TinyDB1.GetTags.
As already said in the forum, generally I would use a list of lists and store it in only one tag in TinyDB

This may be a silly question, but is it possible to make a query using XPath without specifying the element name?
Normally I would write something like
//ElementName[#id = "some_id"]
But the thing is I have many (about 40) different element types with an id attribute and I want to be able to return any of them if the id fits. But I don't want to make this call for each type individually. Is it possible to search all of them at once, regardless of the name?
I am using this in an XQuery script, if that offers any help.
use * instead of name //*[#id = "some_id"]
It might be more efficient to look directly at the #id elements - //* will work, but will initially return every node in the document and then filter!
That may not matter in a small document, of course. but here's an alternative:
//#id[.="some_id"]/..
When using the dollar-dollar-function in prototype I alway get an array of elements back, instead of just one element with the dollar-function. How can I combine the power of CSS-selectors of $$ but still get only one element back?
Changing the structure of the source is not possible, so I can't just select it with the id. It needs to get selected with CSS, but should just return one element.
You can also do
$$('.foo').first()
It looks cleaner than $$('.foo')[0] for my taste :)
It does not make sense to return a single element when selecting by class name because potentially there could be many elements in the DOM that have this class. So you could always use the first element of the returned array if you are sure that it will be unique.
$$('.foo')[0]
