我们的Windows窗体应用程序遇到问题,因为堆栈跟踪指示的类型为AccessViolationException的未处理异常在ToolTip控件中发生,所以它正在终止。
错误发生在应用程序的不同时间,我们目前无法可靠地重现它。 在这个阶段,它仅在Windows 7的生产中发生,并且仅针对某些用户,而不是其他用户 - 即使在以类似方式使用该应用程序的用户中也是如此。 它看起来与机器有关,所以我们做了一些事情,比如确保图形驱动程序是最新的。
在事件日志中,始终记录了2个不同的错误,其中一个与我们的应用程序有关:
Application: <Application>.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

第一个堆栈跟踪根据工作流中错误发生的位置而变化,但是,堆栈中的前9项始终相同,差异通常是出现在Main()方法和RunMessageLoop方法。 E.g:
Application: <Application>.exe

----更新----
我有一个请求要包含Main的一些代码,我不想包含所有代码,但摘录是:
<System.STAThread()> _
Public Shared Function Main(ByVal args() As String) As Integer
-- Perform startup validation, setup logging framework, etc
...
Dim appLife as new ApplicationContext(myStartupForm)
Application.Run(appLife)
Return 0
End Function
一些补充说明:
有谁知道造成这种情况的原因是什么?
谢谢,
答案 0 :(得分:22)
根据MS,在某些情况下DataGrid控件存在已知问题,避免此问题的方法是禁用DataGrid控件的工具提示。
我们将在接下来的几天内实施变更并将其推广到试点小组,我将在大约一周后回复成功/失败(除非当然在此之前发生失败)。
根据MS设置的属性为DataGridView.ShowCellToolTips = false;
这解决了我们申请的问题。
要重现此问题,我们需要执行以下操作:
答案 1 :(得分:10)
似乎在DataGridView.ShowCellToolTips = false
上设置Form.Deactivate
可以防止崩溃。它可以在Form.Activate
上重置为true。
工具提示仍会显示在新聚焦的窗口上方 - 但我想这会比崩溃更好。
甚至更好:
仅在未启用视觉样式时才会出现此问题。
在实例化任何表单之前在Application.EnableVisualStyles()
中添加main()
可以解决问题。

6年后,遗憾的是仍然使用comctl v6&#34;
