ok ive got a basic mesh loaded and now i want to move it around with mouse , ive followed the sdk sample and some tuts on the web but i cant get it to work ,

case WM_MOUSEMOVE:
			{
				//MessageBox(NULL,L"mouse moved" , L"",0);
				POINT lp;
				char Text[64];
				DWORD written;
				GetCursorPos(&lp);
				//X
				sprintf(Text , "%s %i\n" ,"lp.y" , lp.y);
			    WriteConsole(ConsoleHandle , Text , strlen(Text) , &written , NULL);
				//Y
				sprintf(Text , "%s %i\n" ,"lp.x" , lp.x);
			    WriteConsole(ConsoleHandle , Text , strlen(Text) , &written , NULL);


				d3ddev->GetTransform(D3DTS_WORLD , &world);
				
				
				v.x = ( ( ( 2.0f * lp.x ) / SCREEN_WIDTH ) - 1 ) / world._11;
				//mouse pick X
				sprintf(Text , "%s %i\n" ,"v.x" , v.x);
			    WriteConsole(ConsoleHandle , Text , strlen(Text) , &written , NULL);


                v.y = -( ( ( 2.0f * lp.y ) / SCREEN_HEIGHT ) - 1 ) / world._22;
				//mouse pick Y
				sprintf(Text , "%s %i\n" ,"v.y" , v.y);
			    WriteConsole(ConsoleHandle , Text , strlen(Text) , &written , NULL);
                
				//mouse pick Z
				v.z = 1.0f;

			  //convert
			   D3DXMATRIX matView;
               D3DXMATRIX m;
               D3DXVECTOR3 rayOrigin,rayDir;
               D3DXMatrixInverse( &m, NULL, &matView );

              // Transform the screen space pick ray into 3D space
              rayDir.x = v.x*m._11 + v.y*m._21 + v.z*m._31;
              rayDir.y = v.x*m._12 + v.y*m._22 + v.z*m._32;
              rayDir.z = v.x*m._13 + v.y*m._23 + v.z*m._33;

			  rayOrigin.x = m._41;
              rayOrigin.y = m._42;
              rayOrigin.z = m._43;

			  // Use inverse of matrix
              D3DXMATRIX matInverse;
              D3DXMatrixInverse(&matInverse,NULL,&matView);

			  // Transform ray origin and direction by inv matrix
              D3DXVECTOR3 rayObjOrigin,rayObjDirection , rayDirection;

			  D3DXVec3TransformCoord(&rayObjOrigin,&rayOrigin,&matInverse);
              D3DXVec3TransformNormal(&rayObjDirection,&rayDirection,&matInverse);
              D3DXVec3Normalize(&rayObjDirection,&rayObjDirection);

			  BOOL ha........;
              float distanceToCollision;

			  D3DXIntersect(meshSpaceship, &rayObjOrigin, &rayObjDirection, &ha........, NULL, NULL, NULL, &distanceToCollision, NULL, NULL);
              if(ha........)
			  {
				sprintf(Text , "%s\n" ,"collision");
			    WriteConsole(ConsoleHandle , Text , strlen(Text) , &written , NULL);
			  }


				break;
			}

No one has replied which probably means we need more of an explanation of what you are trying to do.

...and of whats wrong exactly. Come on people, a little information goes a long way. It also shows at least an attempt at effort.
