C# Sample Code:
UInt32 RequiredSize = 0;
Guid[] GuidArray = new Guid[1];
// read Guids
bool Status = SetupDiClassGuidsFromName("class name here", ref GuidArray[0], 1, out RequiredSize);
if (true == Status)
{
if (1 < RequiredSize)
{
GuidArray = new Guid[RequiredSize];
SetupDiClassGuidsFromName("class name here", ref GuidArray[0], RequiredSize, out RequiredSize);
}
}
else
{
UInt32 ErrorCode;
ErrorCode = GetLastError();
}
VB.Net Sample Code:
Dim ClassName As New StringBuilder("net")
Dim ClassGuid As Guid
Dim GuidSize As Integer = 0
Dim GuidReqtSize As Integer
Dim intRtrn As Integer
intRtrn = SetupDiClassGuidsFromName(ClassName, ClassGuid, GuidSize, GuidReqtSize)
GuidSize = GuidReqtSize
intRtrn = SetupDiClassGuidsFromName(ClassName, ClassGuid, GuidSize, GuidReqtSize)
MsgBox(ClassGuid.ToString)
