Why the collection element is available only the first?

Question

I have a program with which I work through the directive #import. In it I create the new document and for the first page I place TextFrame which is created with parameters by default.

C++

HRESULT hr = CoInitialize(NULL);
_ApplicationPtr myApp("InDesign.Application");
 
DocumentPtr myDoc = myApp->ActiveDocument;
PagePtr myPage = myDoc->Pages->Item[1L];
TextFramePtr myTextFrame = myPage->TextFrames->Add(); // create frame on Page

Now I want to paint frame with one of predefined swatches. I have to give instance of Swatch to frame by FillColor, i.e.

C++

myTextFrame->FillColor = SomeSwatch->Name;

Got the collection:

C++

SwatchesPtr mySwatches = myApp->Swatches;

Got Swatch instance and Swatch Name:

C++

double SwatchCount = mySwatches->Count; //get quantity of elements
std::cout << SwatchCount << std::endl; // SwatchCount = 10
SwatchPtr mySwatch_1 = mySwatches->Item[1L];
_variant_t mySwatchName_1 = mySwatch->Name;

but here the second element isn't available:

C++

SwatchPtr mySwatch_1 = mySwatches->Item[2L]; // m_pInterface = 0x00000000

How get all elements?

Don't "bump" your question.
Add information by all means, but just bumping it to get it back to the top of the list is rude and unnecessary.

what information? I don't know

Precisely.

Solution 1

the docs[^] are perplexing

count would appear to refer to elements in the swatch, length would appear to refer to number of swatches in the array

so, what to do?

barneyman 18-Aug-15 1:47am

have you tried 'length' ?

Nindzzya 18-Aug-15 3:11am

there is only "Count". "lenght" is only in JS (for Indesing model)

unlikely - if it's in the typelib, it's in the api - it's a property tho, so it would be get_length

anyway, there are a number of other ways of iterating thru the swatches, have you tried them?

Swatches->Count = 10 (in my question)

for the first COM is not c++! There are no overloaded operators for COM. The only function to that is the ptr->Item(index). Usually for template smart pointers the element calls return Interface pointers i.e. itemptr = ptr->Item and your ptr->Item[1] will deliver itemptr+1 pointer increment not itemptr->Item(1) explicit call on the returned object.
regards.
