Excel VBA UserForm按唯一ID更新本地及SharePoint工作表求助

问题1：本地Database工作表无法写入combobox、文本框值的根因 #

• 逻辑顺序错误：先执行本地数据写入，后执行表单必填校验，一旦校验触发Exit Sub，写入逻辑本身可能被提前中断，且错误写入的脏数据不会回滚
• 错误吞掉：开启On Error Resume Next后没有关闭，写入过程中如果出现单元格权限、控件取值错误都会被直接忽略，无法感知异常
• 控件取值问题：绑定数据源的combobox控件直接取.Value可能返回绑定列的隐式值而非下拉选择的显示值，需用.Text取界面可见的选中内容
• 工作表限定缺失：写入时未明确指定工作表对象，切换窗口激活其他工作表时会出现写入位置偏移

问题2：SharePoint共享表更新逻辑异常根因 #

• Find方法未绑定工作表对象：所有Cells.Find调用前未指定所属工作表，默认取当前激活的工作表，大概率找错范围
• 未判断查找结果是否为空：如果SharePoint表中不存在对应UID的行，直接调用ActiveCell.EntireRow操作会导致数据写到错误位置
• 依赖激活/选择操作：大量使用Select/Activate/ActiveCell这类不稳定的操作，窗口切换过程中很容易出现选中位置偏移
• 进程残留问题：中途报错时Application.Visible = False会导致Excel进程驻留后台，锁定文件无法编辑
