Subject: Re: MFColor.Add Method
Sender: mutafchiev@gmx.de 31.08.07 05:52
Hi, I have oneqestion, maybe someone can help me.
Is there any difference of using between MFVec3f.Add and
MFColor.Add Method. Of course the values for RGB
colors must be in the range [0, 1]. For MFColor.Add I do
almost the same as for MFVec3f.Add but the blue color is
always 0.

Thanks a lot!

And this is my code here.
Any suggestions why it does not work are appreciate!!!

// Create the safe array
    const int iCount = 3;
    SAFEARRAYBOUND sSABound[1];
    SAFEARRAY *pSA;

    sSABound[0].cElements = iCount;
    sSABound[0].lLbound = 0;
    pSA = SafeArrayCreate(VT_VARIANT, 1,
        sSABound);

    // Gain access to the values
    VARIANT *pVal = NULL;
    HRESULT hResult = SafeArrayAccessData
        (pSA, (void**)&pVal);
    if (SUCCEEDED(hResult)) {
        // Populate the array
        VariantInit(pVal);
        pVal[0].vt = VT_R4;
        pVal[0].fltVal = 1.;
        VariantInit(pVal + 1);
        pVal[1].vt = VT_R4;
        pVal[1].fltVal = 1.;
        VariantInit(pVal + 2);
        pVal[2].vt = VT_R4;
        pVal[2].fltVal = 1;
        SafeArrayUnaccessData(pSA);
    }
    else {
        SafeArrayDestroy(pSA);
        //return false;
    }
// Initialise the variant
    VARIANT sVarArray;
    VariantInit(&sVarArray);

    // Set the type and value
    sVarArray.vt = VT_ARRAY | VT_VARIANT;
    sVarArray.parray = pSA;

    // Set the optional before param
    VARIANT sVarBefore;
    VariantInit(&sVarBefore);
    sVarBefore.vt = VT_ERROR;
    sVarBefore.scode =
        DISP_E_PARAMNOTFOUND;

if(FAILED(colors->Add(&sVarArray, &sVarColorBefore)))
        ;

As result I have yellow color because the blue value
of the RGB is always zero!!!
