Hi,
i select every object which has the same materiall. So all objects with the same material will be selectet step by step. The right objects get selectet, this works but i need the count of the selectet elements and this doesnt work, as result i only get 0 selectet elements even if the objects are selectet at the object manager. So my code looks likte this.
AutoAlloc<Baseselect> bsobs;
long zaehler = bsobs->GetCount();
Can you help me? I think i need a reference for the baseselct to the objectmanager.... -

long zaehler = bsobs->GetCount();AutoAlloc<> only reserves memory for the array, but is not filled (how should it know what to fill it with). GetActiveMaterials fills the array with the currently selected materials.

Thx i know that something like that was missing but i didn't know what exactly it was ^^
But does this even select the selectet objects, because the count of these i need? -

arg sorry, for objects of course it must be GetActiveObjects(bobs) instead of GetActiveMaterials(). I just woke up
But no, it won´t select them. They must be selected already.
But you cna select objects easily with SetActiveObject(obj,SELECTION_ADD) or SetBit(BIT_ACTIVE);
Hope that helps

Forgot to mention that if you always want all document objects, a shortcut is this instead:
// Get the currently selected objects in the current document
AutoAlloc<AtomArray> bsobs;
AppendAllDocObjects(bsobs, GetActiveDocument()->GetFirstObject());
LONG count = bsobs->GetCount();
...
// Recursive method to append all objects in document into atomarray
void AppendAllDocObjects(AtomArray* array, BaseObject* obj)
{
while (obj)
{
if (obj->GetDown()) AppendAllDocObjects(array, obj->GetDown());
array->Append(obj);
obj = obj->GetNext();
}
}And, of course, you can add your filtering code to AppnedAllDocObjects() to append conditionally (based on material, for instance).

ok, then in the recursive method i chick if the object is selectet and if it so i append it at the array but how do check if the object is slectet or not?

GetActiveObjects() fills AtomArray with every selected object in the document. The TRUE argument says to consider selected children as well - otherwise only selected parent objects are appended to the AtomArray. With GetActiveObjects(), you don't have to check whether or not objects are selected.
I think that you are confusing 'selecting' and 'selected'. Selecting objects in the document requires SetBit(BIT_ACTIVE) or user-interactive selection (PERIOD - there is no other way to select objects). Getting the selected objects into an AtomArray is best done with GetActiveObjects().
So, you've selected all of the objects in the document with a particular material (either by selection in the Object Manager, Editor, or by obj->SetBit(BIT_ACTIVE)). They are 'selected'. No need for 'selecting' at this stage.
Now you want to know how many are selected. You do this:
// Get the currently selected objects in the current document
AutoAlloc<AtomArray> bsobs;
GetActiveDocument()->GetActiveObjects(bsobs, TRUE);
LONG count = bsobs->GetCount();GetCount() returns the number of objects added to the AtomArray. This happens to be the same as the number of currently selected objects in the document.
Now, if your problem is programmatically 'selecting' the objects that meet the same material criteria, then you need to do the recursive method and find the matching material and call SetBit() if it matches. If you want to be thorough, you can call DelBit() for any non-matches to mitigate existing user object selections.
