i.e., could it be that a DDRAWERRxxx is defined as the same value as a D3DERRxxx? i am asking because i want to write a generic function that converts all directx errors into strings. btw: are there any complete lists of all directx error values, so i don''t have to type them in manually? preferrably in form: case errorvalue: return "errorstring"; (for example) case DDRAWERR_UNINTIALIZED: return "DDRAWERR_UNINTIALIZED"; thanks rid

Yes, some error values of DD and 3D have the same value.

But before you bother to write your own function take a look at the D3DXGetErrorString() function that comes with the DirectX7 SDK. It saves a lot of work even if you don''t want to use any other of the D3DX helper functions.
