Hi Rico,

maybe it's just me misunderstanding this, but:

+    FLOAT fvalue[EFFECT_PARAMETER_VALUE_ARRAY_SIZE];
+    D3DXMATRIX *matrix_pointer_array[sizeof(fvalue)/sizeof(D3DXMATRIX)];
+    UINT l, k, m, element;
+
+    for (element = 0; element <= res_desc->Elements + 1; ++element)
+    {
+        memset(fvalue, 0xab, sizeof(fvalue));
+        for (l = 0; l < element; ++l)
+        {
+            matrix_pointer_array[l] = (D3DXMATRIX *)&fvalue[l *
sizeof(**matrix_pointer_array) / sizeof(*matrix_pointer_array)];
+        }

I don't quite understand what you're trying to achieve with
"sizeof(**matrix_pointer_array) / sizeof(*matrix_pointer_array)". As
far as I can see, that depends on the size of the pointer (32/64 bits)
and I'm not sure that the offset should change in that case. Maybe you
meant to use sizeof(float) as divisor?
