ATI SDK problem

[saikamaldoss]

Hello, i am trying to create a fan control for my tool and i don't understand lot of things that the SKD talks about..

here is what i am doing click here

here is the full detail

the code is suppose to be

internal delegate int ADL_Overdrive5_FanSpeed_Get (int iAdapterIndex, int iThermalControllerIndex,ref ADLFanSpeedValue lpFanSpeedValue);



=========================================================


enum iSpeedType{ADL_DL_FANCTRL_SPEED_TYPE_PERCENT,ADL_DL_FANCTRL_SPEED_TYPE_RPM};
enum ipSpeedValue{ADL_DL_FANCTRL_FLAG_USER_DEFINED_SPEED}

now i am trying to get the fan speed which is giving me a hard time......... can some one help please


my code

int ADLRet = -1;
int NumberOfAdapters = 0;

if (null != ADL.ADL_Main_Control_Create)
ADLRet = ADL.ADL_Main_Control_Create(ADL.ADL_Main_Memory_Alloc, 0);
if (ADL.ADL_SUCCESS == ADLRet)
{
if (null != ADL.ADL_Adapter_NumberOfAdapters_Get)
{
ADL.ADL_Adapter_NumberOfAdapters_Get(ref NumberOfAdapters);
}
Console.WriteLine("Number Of Adapters: " + NumberOfAdapters.ToString() + "\n");

if (0 < NumberOfAdapters)
{
ADLAdapterInfoArray OSAdapterInfoData;
OSAdapterInfoData = new ADLAdapterInfoArray();

ADLFanSpeedInfoArray OSAFanSpeedInfoData;
OSAFanSpeedInfoData = new ADLFanSpeedInfoArray();

if (null != ADL.ADL_Adapter_AdapterInfo_Get)
{
IntPtr AdapterBuffer = IntPtr.Zero;
int size = Marshal.SizeOf(OSAdapterInfoData);
AdapterBuffer = Marshal.AllocCoTaskMem((int)size);
Marshal.StructureToPtr(OSAdapterInfoData, AdapterBuffer, false);

ADLRet = ADL.ADL_Adapter_AdapterInfo_Get(AdapterBuffer, size);
if (ADL.ADL_SUCCESS == ADLRet)
{
OSAdapterInfoData = (ADLAdapterInfoArray)Marshal.PtrToStructure(AdapterBuffer, OSAdapterInfoData.GetType());
int IsActive = 0;

for (int i = 0; i < NumberOfAdapters; i++)
{
if (null != ADL.ADL_Adapter_Active_Get)
ADLRet = ADL.ADL_Adapter_Active_Get(OSAdapterInfoData.ADLAdapterInfo.AdapterIndex, ref IsActive);


ADLRet = ADL.ADL_Overdrive5_FanSpeed_Get(OSAdapterInfoData.ADLAdapterInfo.AdapterIndex, 0, ref iSpeedType);


if (IsActive == 1)
{
string Actadapt = System.Convert.ToString(0 < IsActive);
Active_Adap_num_lbl.Text = Actadapt;

string Adapvalue = System.Convert.ToString(NumberOfAdapters);
Adap_num_lbl.Text = Adapvalue;

I hope some one has the knowledge to help on this...
