I'm getting the error APIERR_REFUSEDCMD (-2130312312) when I try to create a polyline. The code below is much simplified and with extra comments...Am I missing something?
void DrawPoly(void){
API_ElementMemo memo;
API_ElementMemo* pMemo = &memo;
API_Element newPoly;
API_Element* pNewPoly = &newPoly;
GSErrCode err;
BNZeroMemory(pNewPoly,sizeof(API_Element));
BNZeroMemory(pMemo,sizeof(API_ElementMemo));
pNewPoly->header.typeID = API_PolyLineID;
pNewPoly->header.layer = 1;
pNewPoly->header.floorInd = 1;
pNewPoly->polyLine.poly.nArcs = 0; //no arcs
pNewPoly->polyLine.poly.nSubPolys = 1; //no holes
pNewPoly->polyLine.poly.nCoords = 4; //a closed triangle
//allocate space for 3points + final point to close shape + space for storing max vertID = 5
pMemo->vertexIDs = (unsigned long **) BMAllocateHandle(sizeof(long) * (5), ALLOCATE_CLEAR, 0);
(*pMemo->vertexIDs)[0] = 3; //max vertexID
//allocate space for pends. no holes, so the 4th vert is the only endpoint.
pMemo->pends = (long **) BMAllocateHandle(sizeof(long) * 2, ALLOCATE_CLEAR, 0);
(*pMemo->pends)[0] = 0; //required
(*pMemo->pends)[1] = 4; //4th vert closes the shape
//allocate space for the coord array. 4 vertices + the dummy coord.
pMemo->coords = (API_Coord **) BMAllocateHandle(sizeof(API_Coord) * 5, ALLOCATE_CLEAR, 0);
(*pMemo->coords)[0].x = -1.0; //polylines start with a "dummy" coord of -1,0
(*pMemo->coords)[0].y = 0.0;
//setup complete....add vertices.
//1st point: 1,1
(*pMemo->coords)[1].x = 1;
(*pMemo->coords)[1].y = 1;
(*pMemo->vertexIDs)[1] = 1;
//2nd point: 2,1
(*pMemo->coords)[2].x = 2;
(*pMemo->coords)[2].y = 1;
(*pMemo->vertexIDs)[2] = 2;
//3rd point: 1,2
(*pMemo->coords)[3].x = 1;
(*pMemo->coords)[3].y = 2;
(*pMemo->vertexIDs)[3] = 3;
//4th point. Same as point 1.
(*pMemo->coords)[4].x = 1;
(*pMemo->coords)[4].y = 1;
(*pMemo->vertexIDs)[4] = 1;
err = ACAPI_Element_Create(pNewPoly,pMemo);
//handle return code...
ACAPI_DisposeElemMemoHdls(pMemo);
}
