I personally haven't used the method your using. But since you have asked if there is another way to do this...

Suppose you have a texture atlas (texture made up of sub-textures) where each sub-texture has the same dimensions:

Then if you create a RECT R = {j*64, i*64, (j+1)*64, (i+1)*64};
   ->Where j = currentFrame / 6     //row 
   ->Where i = currentFrame % 6     //col
        ->(6 because of 6 sub-textures in a row)
   ->Where 64 is the width and height of the sub-tecture

You would simply use this line to draw:

mSprite->Draw(yourTexture, &R, &mSpriteCenter, 0, D3DCOLOR_XRGB(255, 255, 255));

So as you update your currentFrame in an update method, this will effectively update your rect to be draw from the texture.
