CoolTrayIcon我试过了,是能解决这个问题得,不过关键CoolTrayIcon是Delphi的控件,好像没有BCB的版本吧?

const DWORD WM_RESTORE = WM_USER+1;
void __fastcall TForm1::WndProc(Messages::TMessage & Message)
{

TForm::WndProc(Message);
if(Message.Msg==WM_RESTORE)
{

if(IsIconic(Application->Handle))
{

Application->Restore();

}
else{
Application->BringToFront();
}
}

看看你执行这句的前后有没有其他代码影响它。我也用了这个代码，没有你这样的问题
Shell_NotifyIcon(NIM_ADD,&nid);
