If you want to create a new texture from a part of an old, look into the copy rects function. I''m not an expert but I think that might be what your lookig for

very funny. thx for help. hahhaha. i don''t speak spanish so a spanish side doesn''t help me much. and "TEXTURE COORDINATES" is a nice word, but not very helpfull
You don't have to map the entire texture onto your quad. Use coordinates less than 1 to map a smaller area of your texure onto the quad.
So that instead of using (for your texure coordinates):
0,0 - 1,0
0,1 - 1,1
You'd use:
0,0 - 0.5,0
0,0.5 - 0.5,0.5
Of course you don't have to use 0.5, the value depends on how many sprites you've got on a texture, and how you've arranged them, but hopefully you get the idea.

yes this is true. but i don''t want to put this texture on a quad. i want to put it in the sprite. perhaps for d3d it''s the same but i need something where i can use pixel-coordinates of the bmp which i loaded in the texture. perhaps you know something like this ??

Well I''m not sure exactly what you mean by sprite. If you''re using the ID3DXSprite interface then it lets you specify a source rectangle when you draw it I think.
But it doesn''t sound like you''re using that. You really need to define sprite.
Although actually, I only know about DX8.1, so if you''re using DX7, then I can''t help anyway.
Sorry,
