-- 作者:有点蓝 -- 发布时间:2020/12/24 9:28:00 -- 按钮代码可以运行,肯定就不是按钮代码的问题。检查保存的时候会触发什么事件 |
-- 作者:hbfnmxb -- 发布时间:2020/12/24 9:54:00 -- 提示:定义了过多字段,估计是哪里?已经查了好几遍了。没找到问题出在哪里 |
-- 作者:有点蓝 -- 发布时间:2020/12/24 10:00:00 -- 压缩一下项目,如果使用的是access数据库,使用access打开数据库压缩一下数据库 |
-- 作者:hbfnmxb -- 发布时间:2020/12/24 10:22:00 -- 没使用access数据库,压缩项目,问题依旧! |
-- 作者:有点蓝 -- 发布时间:2020/12/24 10:28:00 -- 请上传实例测试 |
-- 作者:hbfnmxb -- 发布时间:2020/12/24 10:33:00 -- 数据量太大,240M,传不来。刚才我是这样操作了一下。窗口按钮另存文件后。关闭项目,不保存!然后打开项目,再导入窗口按钮,直接读取先前保存的。然后再保存项目。结果错误提示没有了。不提示了,运行按钮公式,一切正常。有点奇怪!!不过问题解决了。谢谢老师。 |
-- 作者:有点蓝 -- 发布时间:2020/12/24 10:48:00 -- 项目文件不要用来存储太多数据,建议使用外部数据库 |
-- 作者:hbfnmxb -- 发布时间:2020/12/24 11:07:00 -- 嗯嗯,谢谢老师!在逐渐地学习!! |
