Windows 7 中一个进程的 GDI 对象上限是多少? [英] What's the upper limit on GDI objects for one process in Windows 7?

问题描述

有一个 GDI 泄漏的应用程序最终会达到 10,000 个已分配的 GDI 对象并崩溃.我尝试增加 GDIProcessHandleQuota 到 20,000，但程序在达到 10,000 个对象时仍然崩溃.我们目前正在修复这个漏洞，但出于好奇——有没有办法增加单个进程的 GDI 限制?还是 10k 是单个应用程序的硬限制?

Have an application with a GDI leak that will eventually hit 10,000 allocated GDI objects and crash. I tried increasing the GDIProcessHandleQuota to 20,000, but the program still crashed when it reached 10,000 objects. We're currently working on patching this leak, but out of curiosity--is there a way to increase the GDI limit for a single process? Or is 10k an individual application's hard limit?

推荐答案

有一个可行的解决方案.我在这里处理一个行为不端的供应商应用程序，它分配了大量的 GDI 对象，这个解决方案允许它在大多数时间工作......

There is a solution that might work. I deal with a misbehaved vendor's app here that allocates tons of GDI objects and this solution allows it to work most of the time...

做

reg query "HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerSubSystems"/v windows

查找 SharedSection= 应该是 3 个用逗号分隔的数字.一次将中间数增加 1024，看看是否能解决您的问题.您正在使用此变量控制桌面堆"的数量，这在过去允许我运行行为不端的 GDI.

Look for SharedSection= which should be 3 numbers separated by commas. Increase the middle number by 1024 at a time and see if that solves your problem. You are controlling the amount of "desktop heap" with this variable which has in the past allowed me to get a misbehaving GDI running.
