VARIANT 小错误引起大问题.

一日,发现程序从 1->2->3 中 , 1的传值是正确的, 2把传值包装到VARIANT中去, 可是到了3有一个值就出现预料外的值.总是设置为true;

varProxy.vt = VT_BOOL ;
varProxy.bVal = Global::stGlobalInfo.bProxy?VARIANT_TRUE:VARIANT_FALSE ;

问题就在第二句, bVal 是一个 BYTE , 而不是BOOL , 一粗心就写成了bVal , 而不是boolVal .

VARIANT_TRUE 是 0xFFFF

VARIANT_FALSE 是 0x0000

但是使用bVal 则分别变成了 0xFF/0x00 高位内容无法预测(极有可能非0), 使得一直返回非0,即TRUE
