Hi Everyone,

I was trying to get the transformation matrix for mating two bodies, but I have a problem in calling GetCoincidenceTransform() correctly. I always got "Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call." How can I call the function properly? Because I thought all parameter already set as requested.

Moreover, why hr is still having S_OK although having that failure?

Please help me point out the problem. Many thanks, isnaini

Here is my implementation code:

--------------------------

void mateComponent(IBody2 * mainBody, IBody2 * otherBody)

{

IMathTransform * mTransform1 = NULL;

//CComPtr  mTransform1, mTransform2;

//double x, y, z, xform1[16], xform2[16];

HRESULT hr = NOERROR;

VARIANT_BOOL boolVal = VARIANT_FALSE;

IDispatch *pBody = otherBody;

try

          {

                    //Get Matrix

  hr = mainBody->GetCoincidenceTransform(pBody, &mTransform1, &boolVal);

                    //mTransform1->get_IArrayData(xform1);

                    //otherBody->Copy(&pBody);

                    //hres = otherBody->GetCoincidenceTransform(otherBody, &mTransform2, NULL);

                    //mTransform2->get_IArrayData(xform2);

          }

          catch (_com_error e)

          {

                    CoUninitialize();

                    MessageBox(NULL, e.ErrorMessage(), NULL, MB_OK | MB_SETFOREGROUND);

                    exit(EXIT_FAILURE);

          }

}
