在一函数内，自动以隐藏方式打开文档，处理完数据后，自动关闭。在本人机器上没什么问题，但在同事的机器上，会出现异常，经调试，发现是调用onclosedocument（)的时候发生异常，在之前如果加一个messagebox就没有问题，俺完全不知道是怎么回事拉，那位大虾帮俺看看？
问题代码段：
g_bshowwindow = false;
cdocument* pdoc = afxgetapp（)-> opendocumentfile（strflowpath);
...
pdoc-> onclosedocument（);
cchildframe的activateframe：
void cchildframe::activateframe（int ncmdshow)
{
if（ getmdiframe（)-> mdigetactive（) != null )
{
if（ g_bshowwindow )
{
cmdichildwnd::activateframe（ncmdshow);
}
else
{
cinitialmodule::setshowwindow（ true );
cmdichildwnd::activateframe（ sw_hide );
}
}
else
{
cmdichildwnd::activateframe（sw_showmaximized);
}
}
