 |
|
I want to put the contents of a CIM: CIM_UINT64 type variable into a Memo
as in:
long type ;
unsigned long HwCode, uReturned;
WideString key;
Variant value;
while((HwCode = pEnumerator->Next(WBEM_INFINITE, 1, &pclsObj, &uReturned))
== S_OK)
{
pclsObj->BeginEnumeration(0);
while ((HwCode = pclsObj->Next(0, &key, (VARIANT *)&value, &type,
NULL)) == WBEM_S_NO_ERROR)
{
if (type == 21 /*(21 is CIM_UINT64)*/ && value.Type() !=
varNull){
int test = value.AsType(varInteger);
Form1->Memo1->Lines->Add(String(test));
}
}
}
But I get a "Invalid Varient Conversion" error. The field in question from
the Wmi code snippet is a type CIM: CIM_UINT64 which translates into a C++:
unsigned __int64. Any insight is appreciated.

varInteger is not an '__int64', it is an 'int'. You cannot cast an
'__int64' Variant to an 'int'. Use varInt64 instead. Also, Variant does
not support 'unsigned __int64' to begin with, only 'signed __int64'.
__int64 test = value.AsType(varInt64);
Besides, you don't need to cast anyway. The Variant already contains a
value, and Variant already supports converting itself to an AnsiString, so
just assign the Variant to the Memo directly:
Form1->Memo1->Lines->Add(value);
