I want to done through the code.

So give your suggestion about this.

case WM_INITDIALOG:<br />
   hIcon = LoadIcon(hInst,(LPCWSTR)IDI_ICON1);<br />
   hStart = GetDlgItem(hWndDlg,IDC_Start);<br />
   LRESULT lr = SendMessage(hStart,BM_SETIMAGE,(WPARAM)IMAGE_ICON,(LPARAM)hIcon);<br />
   if(lr != NULL)<br />
           {<br />
              OutputDebugString(L"Error");<br />
            }<br />
<br />
break;<br />

<br />
case WM_INITDIALOG:<br />
SetWindowLong( GetDlgItem(hWndDlg, IDC_BUTTON1 ), <br />
               GWL_EXSTYLE,<br />
              GetWindowLong( GetDlgItem(hWndDlg, IDC_BUTTON1 ), GWL_EXSTYLE ) |SS_ICON );<br />
	break;
