defragdialog.cpp

ReactOS是一些高手根据Windows XP的内核编写出的类XP。内核实现机理和API函数调用几乎相同。甚至可以兼容XP的程序。喜欢研究系统内核的人可以看一看。

#include "DefragDialog.h"
#include "Defragment.h"
#include "resource.h"


void UpdateDefragInfo (HWND Dlg)

    Defragment *Defrag;
    HWND PercentItem;

    Defrag = (Defragment *) GetWindowLongPtr (Dlg, GWLP_USERDATA);
    
    sprintf (PercentText, "%6.2f%%", Defrag->GetStatusPercent());
    PercentItem = GetDlgItem (Dlg, IDC_PERCENT);
    SendMessage (GetDlgItem (Dlg, IDC_PERCENT), WM_SETTEXT, 0, (LPARAM) PercentText);
    SendMessage (GetDlgItem (Dlg, IDC_STATUS_TEXT), WM_SETTEXT, 0, (LPARAM) Defrag->GetStatusString().c_str());

    return;
}
