带有System.Drawing.dll/NumericUpDown的.NET访问冲突异常 [英] .NET Access Violation Exception with System.Drawing.dll / NumericUpDown

问题描述

我遇到了一个非常愚蠢的问题.我尝试完全重新安装.NET，但尚未解决问题.通过Google搜索，我什至找不到其他遇到相同问题的人.

I'm suffering a really stupid problem. I've tried completely reinstalling .NET and it hasn't fixed the problem. I can't even find anyone else with the same problem by Googling.

就在我的计算机上，如果我将NumericUpDown控件添加到.NET项目中的表单并运行该应用程序，则在运行该应用程序时会收到以下错误消息:

Just on my computer, if I add a NumericUpDown control to a form in a .NET project and run the application, I get the following error message upon running the application:

类型为'System.AccessViolationException'的未处理异常发生在System.Drawing.dll

An unhandled exception of type 'System.AccessViolationException' occurred in System.Drawing.dll

其他信息:尝试读取或写入受保护的信息记忆.这通常表明其他内存已损坏.

Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

该应用程序可以在其他计算机上正常运行.

The application runs fine on other machines.

有什么建议吗?

推荐答案

问题原来与显卡有关.我们发现一台同事的机器也有同样的问题，这是因为两台机器最近都装有相同的廉价图形卡(Radeon HD5450).两者都在运行最新的驱动程序.

Problem turned out to be graphics card related. We found a colleagues machine with the same issue, it just so happens both machines were recently fitted with the same cheap graphics card (Radeon HD5450). Both were running latest drivers.

没有解释为什么这些卡/驱动程序会导致此问题.但是卸下卡并还原为板载图形可以解决此问题.该计划是尝试使用几个便宜的GEForce 210.

No explanation as to why these cards/drivers caused this problem. but removing the cards and reverting to onboard graphics fixed the issue. The plan is to try a couple of cheap GEForce 210's instead.

我意识到这本身并不是编程问题，但这可能会节省其他人几个小时的屁屁！

I realise this wasn't a programming issue per se, but this might save someone else a few hours of fart arsing around!
