在Windows 7上使用Windows窗体在Visual Studio 2017中获取以下错误。这种情况发生在多台计算机上。我在标签中有一组编辑框,当在组合框中选择一个“表单”时,它们都被设置为隐藏或可见。我会将文本导入到这些编辑框中,滚动滚动或通过组合框的上/下箭头选择要显示或隐藏的不同标签,最终这些窗体中的编辑框会变为空白。当你去输入编辑框时,你会得到内存错误。我搜索并搜索了一个没有运气的解决方案。任何帮助将非常感激。C#保护内存错误,缓慢地杀死我的大脑

我们可以看到一些代码吗?你能提供一个再现问题的最简单的例子吗?我们也从查看鼠标滚轮和查看事件处理程序开始。 – khargoosh
就处理程序而言,我没有使用鼠标滚轮进行任何设置。我甚至不知道代码的哪一部分导致了这一点。这似乎是一个普遍的错误,我不知道在哪里查明确切原因。 – DasGoat
你在做任何p/invoke调用吗?开始从应用程序中删除东西,直到问题消失。那么你至少缩小了它的范围。然后...向我们展示代码。 – khargoosh
