Convert uint16 to WMI Variant for CreateSnapshot Method

Question

I want to call CreateSnapshot Method which is a call to provider but I am stuck as I cannot set the input parameter for Snapshot Type which is expected as uint16. This is passed using a Variant. The code snippet is below.

VARIANT var;
VariantInit(&var);
V_VT(&var) = VT_BSTR;
V_BSTR(&var) = SysAllocString(L"32768");

hr = pInParams->Put(L"SnapshotType", 0, &var, CIM_UINT16);

cout << "\nValue Set Is: "<<var.uintVal<<endl;

I am not able to pass the required value. Any points on what I am doing wrong ?

Note: Put method is working fine with HRESULT as 0 but CreateSnapshot is unsuccessful.

EDIT

Msvm_VirtualSystemSnapshotService Class -> CreateSnapshot has the following prototype

uint32 CreateSnapshot(
[in]      CIM_ComputerSystem           REF AffectedSystem,
[in]      string                           SnapshotSettings,
[in]      uint16                           SnapshotType,
[in, out] CIM_VirtualSystemSettingData REF ResultingSnapshot,
[out]     CIM_ConcreteJob              REF Job
);

Answer 1

BSTR paramName3 = L"SnapshotType";
VARIANT var;
var.vt = VT_UI2;
var.iVal = (uint16_t)32768;

hresult = pInClass->Put(paramName3,
    0,
    &var,
    CIM_UINT16);
if (FAILED(hresult))
{
    string msg = "Failed to set property.";
    throw std::exception(msg.c_str());
}
VariantClear(&var);

as question，convert unit16 to varint and it's work
