GDI句柄在DotNET应用程序中 [英] GDI handles in a DotNET application

问题描述

我的纯DotNET库在非托管桌面应用程序中作为插件运行。我已经得到一个稳定（虽然低）的崩溃报告流，似乎表明GDI句柄（错误消息中的字体等）恢复到系统字体的问题，显示所有种类的控件分解，大规模崩溃后不久）。

My pure DotNET library runs as a plugin inside an unmanaged desktop application. I've been getting a steady (though low) stream of crash reports that seem to indicate a problem with GDI handles (fonts in error messages etc. revert to the system font, display of all sorts of controls break down, massive crash shortly after).

我的表单有几个控件，但我在用户控件中做了很多GDI +绘图。

My Forms have few controls, but I do a lot of GDI+ drawing in User controls. What's a good way to tell how many handles I'm using, or even leaking?

感谢，

Thanks, David

推荐答案

我不得不处理过去的同类问题。为了检查您的应用程序分配了多少GDI对象，您可以使用一个免费工具 GDIUsage 。

I've had to deal with the same kind of problem in the past. In order to inspect how many GDI objects your application is allocating you can use a free tool called GDIUsage.

在我的情况下，应用程序崩溃，因为它分配的 10.000 GDI对象限制在Windows XP。

In my case the application was crashing because it was allocating more than 10.000 GDI objects, which is a hard limit in Windows XP. It might be worth looking into it.
