Help with loading meshes.

For some reason, my code from beginning game programming by jonathan Harboaur doesn't load the textures. here is the modified code from his book. I've mad a class to be able to load meshes and position them. here it is:
it doesn't seem to load the textures of the model, what should i do?
the problem may be that you have to have the mesh in the same folder as the .exe, as it loads the filepath as "mesh.x" , and not an absolute path.
I guess there are ways around it, like creating a string with the beginning of the absolute path in it, then combining the strings while running through the loop, but for just learning, try throwing a copy of the mesh in the folder with the project file, as well as in the debug folder.

Ok, that worked. but it doesn't seem like a good idea to have all the meshes in the same folder as the EXE as that would be too consufibg, any way that i can make it work by putting the models in a folder and loading them and have them show up with the texture on?
add the beginning of the absolute path to the beginning of the string when leading hte texture, or go into the .x file and change the filepath to what it needs to be, those are 2 quick solutions i can think of but i don't know how the "pros" do it, as i just started 3D stuff a month ago
