GDI处理在DOTNET应用 [英] GDI handles in a DotNET application

问题描述

我的纯DOTNET库运行作为一个插件非托管的桌面应用程序中。我已经得到的崩溃报​​告的稳定（虽然低）流似乎表明与GDI处理的问题（错误信息等字体恢复到系统字体，种种控制显示器后不久分解，大量的碰撞）。

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).

我的形式有一些控制，但我做了很多的GDI +的用户控件绘制。什么是一个很好的方式来告诉我有多少手柄使用，甚至泄露？

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?

谢谢， 大卫

推荐答案

我不得不处理在过去同样的问题。为了检查许多GDI对象如何您的应用程序分配您可以使用一个名为免费工具 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，因为它是分配超过 10.000 GDI对象，这是在Windows XP中的硬性限制。这可能是值得探讨的。

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.
