You have a typo. You are querying for edges and node, not nodes. So your code should look like:

You can provide the full path from the root folder. Then you do not need to cd inside any dirs.

The problem that you might be misunderstanding is that calling free(temp) releases the object in memory pointed to by temp - it doesn't really have anything to do with the temp variable itself. temp will be deallocated once the function returns. In fact, declaring temp itself might even be unnecessary.

Java and Kotlin strings are immutable and not editable in place. replace() returns a new string that you're throwing away.

One way to fix that is change the val string to a var string and assign the returned string back to it.

DirectShow filter is a COM object without requirement or assumption to implement any self-descriptive interfaces. There is no DisplayName attached, promised or documented, so you don't have a method to retrieve it.

DisplayName is a string associated with registration information, and if a filter is not registered as in your example you mention, then there is no DisplayName in first place.

Moniker is a "shortcut" to instantiate a filter. Once you have an instance, there are no more monikers in the game.

The best you can do in the situation, is to attempt to recover CLSID for the instance you are holding (see, for example, Getting GUID of coclass object using pointer to interface it implements), and then look the registry up for COM class description (optional too, but exists in most cases).

You only need 1 Modal. So you can move Modal out of your map.

Then, you need to figure out how to indicate which artist to show in the Modal.

One way to do that is to pass the artist.id:

thread that does CoInitialize will fail if it hasn't message pump. So use CoInitializeEx(NULL,COINIT_MULTITHREADED); if thread doesn't have own one.
But latter case is only for mta com's.
And this doesn't mean you'll just change CoInitialize to CoInitializeEx..
mta com should have own base. And you should provide it. like i've done there https://github.com/alexeyneu/tool3/blob/00bfd2aaf2973626f166ea754b756fd0f2fa0d0b/tool3/MainFrm.cpp#L254

The C implementation of IUnknow is different than C++. The comon way to call QueryInterface is not by using IUnknown_QueryInterface_Proxy (from RpcRT4.lib) but to do this :

Class2.array_1_class2 is blank by default. If you create a Class2 object directly, your C# code does not assign any data to its array_1_class2 member.

Class4.LoadJson() returns a Class1 object, which you are ignoring. Class1 contains a Class2 object whose array_1_class2 member will be populated by LoadJson(). So, in your Delphi code, you should be accessing V_class1.Class2.array_1_class2 instead of V_class2.array_1_class2.

Also, you are using the 3rd parameter of SafeArrayGetElement() incorrectly. Every integer you extract gets saved in LData[0] only, you are never assigning any value to LData[1].

Try something more like this instead:
