c++builder编写托盘程序时Access violation at address 00401DA0 in module 'Project1'.
提示Project Project1.exe raised exception class EAccessViolation with message 'Access violation at address 00401DA0 in module 'Project1'. Read of address 00000168'. Process stopped. Use Step or Run to continue.
void __fastcall TForm1::WndProc(Messages::TMessage& Message)
{
if(Message.Msg==iconmessage)

switch (Message.LParam)

case WM_LBUTTONUP:
//单击图标，启动/停止服务

{
this->Visible = false;

Application->ShowMainForm = false;
return;
}
TForm::WndProc(Message); //对于其他的消息，调用基础类的WndProc函数让Windows进行缺省处理

void __fastcall TForm1::AddTrayIcon() //添加托盘

NOTIFYICONDATA icondata;
memset(&icondata,0,sizeof(icondata));
//将结构icondata的各域初始化为0
icondata.cbSize=sizeof(icondata);

NOTIFYICONDATA icondata;
memset (&icondata, 0, sizeof (icondata));
icondata.cbSize = sizeof (icondata);
icondata.hWnd = Handle;
icondata.hIcon=Image->Picture->Icon->Handle; //为什么此处会报错??????????????????????????????
strncpy (icondata.szTip, tip.c_str(), sizeof (icondata.szTip));
icondata.uFlags = NIF_ICON|NIF_TIP;
Shell_NotifyIcon (NIM_MODIFY,&icondata);
}
icondata.hIcon=Image->Picture->Icon->Handle;这句话为什么会报错
