New Post: CUDAfy and OpenCL parameter error.

Hello, Some time ago i use CUDAfy for CUDA. I was very usefull. So now i try to write some code for OpenCL. And have a trouble with parameters to kernel function.
I try to reduce array size, try many other things...so after all i wrote test code, but it also have this trouble:

            CudafyModule km = CudafyModule.TryDeserialize();
            if (km == null || !km.TryVerifyChecksums())
            {
                km = CudafyTranslator.Cudafy();
                km.Serialize();
            }
            CudafyModes.DeviceId = comboBox1.SelectedIndex; // selecting device (Videocard by default)
            GPGPU gpu = CudafyHost.GetDevice(CudafyModes.Target, CudafyModes.DeviceId );
            textBox1.AppendText(String.Format(Environment.NewLine + "Starting on Device {0} ( {1} )", CudafyModes.DeviceId, gpu.GetDeviceProperties(false).Name) );
            gpu.LoadModule(km);
            gpu.StartTimer();
            UInt32[] partBuf = new UInt32[26];
            UInt32[] dev_items = gpu.Allocate<UInt32>(partBuf); // at this pont we got dev_items size 0!!! is that right?!!
            
            dim3 threads = new dim3(5, 6);
            dim3 grids = new dim3(7, 8);
            gpu.Launch(threads, grids).calc_db_units( 0, 0, 0, dev_items ); // at this point we've got an "OpenCL error code detected: InvalidArgumentSize." error message.

            gpu.CopyFromDevice(dev_items, partBuf);
            gpu.FreeAll();
            gpu.StopTimer();

// Just test function...only for "doing something"...
        [Cudafy]
        public static void calc_db_units(GThread thread, UInt32 definer, UInt16 dp, UInt32 part, UInt32[] generated)
        {
            UInt64 currResult = (UInt64)thread.blockDim.x + ((UInt64)thread.blockDim.y << 8) + ((UInt64)thread.gridDim.x << 16) + ((UInt64)thread.gridDim.y);
            generated[0] = (UInt32)(currResult);
            generated[1] = (UInt32)(currResult >> 32);
        }

So, what i've doing wrong?
Thank you.
