Specifics regarding these components and their functionalities should be asked in Turbopower's community forum or support. This is not a place where you can expect answers to such questions or expect support for 3rd party components.

sprintf does not change Caption's underlying string. It creates a temp string that contains the changed value. But, that temp (changed) value must be assigned to a property in order to change property's underlying value.

"Caption" is a component property and behind that property is a string variable that actually contains the string. Every time you read/write some property value you access it's underlying variable directly or indirectly by it's get/set (read/write) methods (depends of implementation). In this case it seams that the set (write) method of a "Caption" property is not called after sprintf is done, and that is why it's underlying string was not changed. That is why you need to address "Caption" property directly to change it's underlying string value:
Form1->Caption = Form1->Caption.sprintf(L"123");
Calling only
Form1->Caption.sprintf(L"123");
returns a temporary string that is not assigned to a component property and thus not calling it's set (write) method.

It is not an incorrect version. It is just a full version. But your Starter edition will not be able to use most of those things anyway since it's very limited so it would be best for you to simply connect your laptop online so that your setup can download only the files it needs for Starter edition to work.

Did you download online or offline installer? Offline installer should be a few gigs large, while online installer only ~130 MB.

sprintf only returns the value. You must set it yourself.
Form1->Caption = Form1->Caption.sprintf(L"123");

That is very strange. I would try installing again. Upon installation you will be required to enter serial key (or reg/slip file) which would identify your copy as Delphi Starter edition. Also make sure at least one platform is selected (Win32).

Go to 'Help' menu and choose 'License Manager...'. Then you should be able to see if your copy is registered or not.

Register your copy of starter edition. Then you should have an option to create new projects.

'Unresolved external' pretty much means that function/method implementation cannot be found. Looking the documentation it says to use 'exception' header.

Try it.

Hi,
When using search feature for object inspector it only finds properties that are not nested. For example, if a component has a 'Visible' property under few nodes it will not find that property at all. Bug?

Hi,
I have some custom code in the beginning of
int WINAPI _tWinMain(HINSTANCE, HINSTANCE, LPTSTR, int)
function in the main project cpp file.
When adding a new form to a project all my custom code in that function is deleted and rewritten with additional Application->CreateForm.. Is this a bug?

As I remember there were plans to stop using 'classic Borland compiler' as a default one in C++ Builder, but even now I see it is still the default compiler in 10.2?
