  • 工作学习 / IT技术讨论 / help!!! about VARIANT. Thanks in advance. -xiaoxiao(笑笑); 2001-9-18 {300} (#204264@0)
    I defined a VARIANT variable. I passed it as a parameter into a function and this function will modify this variable and store an array in this variable. But I got error messages said " unhandled exception in **.exe(KERNAL32.dll), 0x********* ". anybody who familiar with COM/OLE, please help me.
    • use wrapper class to deal with VARIANT. -mrviceroy(大力神 Daniel); 2001-9-18 (#204350@0)

        • use _variant_t or CComVariant. In fact, they are smart pointers. -mrviceroy(大力神 Daniel); 2001-9-26 (#210639@0)
          • I have create a class of my own to use VARIANT to store an array of data in it. It seems that CComVariant doesn't support array. -xiaoxiao(笑笑); 2001-9-26 (#210688@0)
          • By the way, how can COM servers send message to each other? I mean, If some events happens in COM server A, how could an another Component( Application) know that? -xiaoxiao(笑笑); 2001-9-26 (#210689@0)
            • the easiest way is to use Connection Points. Choose this check box in the Attributes pane when you insert an ATL object. -mrviceroy(大力神 Daniel); 2001-9-26 (#210720@0)
              • Can I know you phone number? I have a hard nut to crack here. -xiaoxiao(笑笑); 2001-9-26 (#210768@0)
