Hello. I am using directx 7 to do a drafting program. the program works fine on the higher end computers but I get an DDERR_NODIRECTDRAWHW error when I run it on an more feeble computer. ok I have it running but there is no texture support. Is there a way to force it to use texture support?

It's not the computer that's feeble, it's the video card. It's telling you that no DD hardware can be found. Can you force it to do textures. In a word, no. But, if you're up to it you can make your own texture manipulation routines and apply them to a surface. But that's really more trouble then it's worth. I would suggest you just use it on a better PC or recomend a video card upgrade.

Do you know any good resources that explain how to do the texture manupulation. I know what needs to be done, but it is pointless to reinvent the wheel. I need this program to run on a wide variety of computers, so I may decide to do the impossible and put in the routines. Do you know if openGL has software emulation?

nVidia's OpenGL does have it but it's very rudamentry and is only to supplament functions on older nVidia chipsets. BUT... DirectX has software emulation. Try using it. Maybe it'll work to solve your problem.
