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

问题描述

具有一个GDI泄漏的应用程序，该应用程序最终将击中10,000个分配的GDI对象并崩溃.我尝试增加 GDIProcessHandleQuota 到20,000，但是程序达到10,000个对象时仍然崩溃.我们目前正在修补此泄漏，但出于好奇-是否有办法提高单个过程的GDI限制?还是10k是单个应用程序的硬性限制?

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

有一种可能有效的解决方案.我在这里处理了一个行为不当的供应商应用程序，该应用程序分配了大量的GDI对象，并且该解决方案使它在大多数时间都可以工作...

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_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems" /v windows

寻找SharedSection=，它应该是3个数字，以逗号分隔.一次将中间数字增加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，该变量过去使我无法正常运行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.
