I could be wrong, but you might have your near a bit off on the orthographicOffCenter, try:

CreateOrthographicOffCenter(0.0f, 1.0f, 1.0f, 0.0f, -1.0f, 2.0f);

It ended up being the z distance thanks.
I dont really understand tho, say I put  0 and -2 as the near and far distance. Am I correct to assume that anything with a Z value between these will be displayed?

Let me rephrase the question, is the zFar value a point in 3d space (making my logic valid) or is it a length in the negative direction from the zNear value(which is what it seems to be)?
by the second explanation I mean for example using -1 and 3 would make anything visible between -1 and -4
