[解决办法]
rs1 有 Open 就要有配对的 Close。
如果 Open 后没有 Close，再次 Open 就会出错。
[解决办法]
在第二次open之前一定要close
直接调试，出错的前一行加来rs1.close就OK
[解决办法]
rs1.Open 下移一行——如果不需要操作（Exit Sub）就不必打开。
rs1.Close 放在 Gotfocus() 的最末。
又：如果 rs1 仅在 Gotfocus() 中调用，就声明在 Gotfocus() 中。
一次性声明所有变量是汇编时代的风格。太 OUT 了！
[解决办法]
if rs.eof and rs.eof
msgbox ....
else
d.open ...
endif
还有，不会是做石材方面的应用吧！？？
[解决办法]
if rs1.state<>adstateclosed then rs1.close
rs1.Open "select * from scandata", cnn, adOpenStatic
