怎样捕获rtl60.bpl异常?

[dcb0917]

异常如下:Access violation at address 40037E17 in module 'rtl60.bpl'. read of address 00000011

[___NULL]

恐怕是你某个控件异常才导致的，一般是内存溢出或者访问了一个无效指针

[ccrun.com]

貌似访问了某个对象的属性，而这个对象是NULL(可能尚未分配资源)。

会不会是三方控件引起的？

[dcb0917]

主要是Win32 API 和 serversocket、clientsocket控件

主要用rtl60.bpl接口如下:

本人做数据采集,这现象随机出现,频率不是太高,可能只有仔细查代码.

用BCB自带的CodeGuard，检查内存问题还不错！
