应该可以得到。

Answer 1

使用消息LVM_????，下面例子是一个Mouse Hook，用来得到用户在资源管理中实时选中的文件，不过是C++Builder代码的：----------------------------------------------LRESULT CALLBACK MouseHook(int nCode,WPARAM wParam,LPARAM lParam)
{
  if(nCode<0) return CallNextHookEx(MouseHookID,nCode,wParam,lParam);  if(HookWindowHandle==NULL)
  {
    HookWindowHandle=FindWindow(HookClassName.c_str(),NULL);
    AppWindow=GetWindow(HookWindowHandle,GW_OWNER);
  }  if((int)wParam != WM_LBUTTONUP) return 0;  MOUSEHOOKSTRUCT *mst=(MOUSEHOOKSTRUCT*)lParam;  //*/
  HWND hLV;
  TPoint P;
  char Buf[64];  P.x = mst->pt.x;
  P.y = mst->pt.y;  hLV = WindowFromPoint(P);  ZeroMemory(Buf,64);
  GetClassName(hLV,Buf,64);
  
  if(AnsiString(Buf) == "SysListView32")
  {
    LV_ITEM Item;
    int ItemCount;
//    char *SelFileNameBuf=new char[64];
    char SelFileNameBuf[64];    ItemCount = ListView_GetItemCount(hLV);    if(ItemCount > 0)
    {
      AnsiString S;      bool IsSuc = false;      for(int i=0; i < ItemCount; i++)
      {
        ZeroMemory(SelFileNameBuf,64);        Item.iItem=i;
        Item.iSubItem=0;
        Item.mask = LVIF_TEXT | LVIF_STATE;
        Item.stateMask = LVIS_FOCUSED;
        //Item.state = -1;
        Item.pszText = SelFileNameBuf;
        Item.cchTextMax = 64;        if(ListView_GetItemState(hLV,i,LVIS_FOCUSED) != LVIS_FOCUSED)
        {
          //SendMessage(HookWindowHandle,WM_SETTEXT,0,(LPARAM)AnsiString("Error Query State="+IntToStr(i)).c_str());
          continue;
        }        if(ListView_GetItem(hLV,&Item))
//        ListView_GetItemText(hLV,i,0,SelFileNameBuf,64);
