Question

I need to edit the resources of a file in C++ using UpdateResource(), however I am unsure on how to go about getting the data for the 5th parameter (lpData).

I have no idea about how to create the data that needs to be provided for the function and the structure of the data, Can anybody provide guidance on how to go about getting/creating the data?

Simply you can use:

wchar_t wszMyText[] = L"Some text";
HANDLE hUpdate = BeginUpdateResourceW( L"/path/to/file", FALSE );
// test return value.
BOOL res = UpdateResourceW( hUpdate, RT_STRING, L"MyResource", wszMyText,
    sizeof(wszMyText) - sizeof(wchar_t);
// check return value
EndUpdateResource( hUpdate, FALSE );
