<p>Windows提供給我們兩個API函數，可以動態(tài)調整顯示器的分辨率，他們是EnumDisplaySettings()
和ChangeDisplaySettings()，下面這個例子就是了<p><span class="p2">function
DynamicResolution(X, Y: word): BOOL;<br>
var<br>
lpDevMode: TDeviceMode;<br>
begin<br>
Result := EnumDisplaySettings(nil, 0, lpDevMode);<br>
if Result then<br>
begin<br>
lpDevMode.dmFields := DM_PELSWIDTH Or DM_PELSHEIGHT;<br>
lpDevMode.dmPelsWidth := X;<br>
lpDevMode.dmPelsHeight := Y;<br>
Result := ChangeDisplaySettings(lpDevMode, 0) = DISP_CHANGE_SUCCESSFUL; <br>
end<br>
end;<br>
<br>
procedure TForm1.Button1Click(Sender: TObject);<br>
begin<br>
if DynamicResolution(640, 480) then<br>
ShowMessage('Now is 640*480');<br>
end;<br>
<br>
procedure TForm1.Button2Click(Sender: TObject);<br>
begin<br>
if DynamicResolution(800, 600) then<br>
ShowMessage('Now is 800*600');<br>
end;</span></p>
