我不断遇到错误，说数据集、表适配器等..类型未定义

问题描述 投票：0回答：1

我正在使用 Visual Studio 2019 创建一个库存控制程序，并一直尝试将其链接到其中一个表单的 Access 数据库。

但是，当我编码时，我的笔记本电脑意外崩溃，之后设计器代码中出现了错误。我知道您不应该编辑此代码，因此我不确定导致这些问题的原因。

也由于这个原因，我的表单变成了空白，但所有按钮、文本框等的代码仍然存在。

我一直在研究解决方案，但我只是尝试任何修复，因为我不想让问题变得更糟。

我已经包含了设计者的代码和错误的屏幕截图。

任何帮助将不胜感激，因为我担心我因遗憾地单击“忽略并继续”而破坏了代码。

谢谢，

好吧，这有点像死线程，但我刚刚遇到了这个问题，它似乎完全是 Visual Studio 生成的代码的错误。

看看你的代码中如何指定它所抱怨的变量的 scope 未定义？ 删除 

Stock_Control.
前缀。

Friend WithEvents OrderTableAdapter As Stock_Control.StockControlDatabaseDataSetTableAdapters.OrderTableAdapter
变为 
Friend WithEvents OrderTableAdapter As StockControlDatabaseDataSetTableAdapters.OrderTableAdapter
。我不知道为什么 Visual Studio 决定它生成的变量在该范围内，但它却无法在该范围内找到它们。

（我在向我的应用程序添加 DataGridView 时遇到了这个问题，它非常高兴地加载了列标题并让我用实际数据预览表，但是当我进行编译时，由于这些变量范围问题而因构建错误而失败。）
