【已解决】笔记本DPI缩放问题，谢谢发哥……

问题出现：_GDIPlus_GraphicsDrawRect 这个函数 在我的笔记本：只能画出屏幕前面1/2的矩形图像，超过的屏幕另外1/2范围的显示不出来…………，找不到问题所在…………
折腾了2天，自己实在搞不定，后面在发哥的帖子找到了答案，加入：SetProcessDPIAware() 函数顺利解决问题，发哥真神人也，想了想，发上来，给有需要的战友，希望大家少走点弯路………………

#include <GdiPlus.au3>

ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') :  @DesktopWidth = ' & @DesktopWidth &@TAB &  '@DesktopHeight= ' & @DesktopHeight  & @CRLF) ;### Debug Console

$iDPI = 2
Local $aPos_Lefttop[2] = ['100', '136']
$iLeft = $aPos_Lefttop[0] * $iDPI 
$iTop = $aPos_Lefttop[1] * $iDPI 

_GDIPlus_Startup() ;initialize GDI+
$hDC = _WinAPI_GetWindowDC(0) ; DC of entire screen (desktop)         ok!
$hGraphics = _GDIPlus_GraphicsCreateFromHDC($hDC)
_GDIPlus_GraphicsSetSmoothingMode($hGraphics, $GDIP_SMOOTHINGMODE_HIGHQUALITY) ;sets the graphics object rendering quality (antialiasing)
$hPen = _GDIPlus_PenCreate(0xFF00FF00, 4) 

For $i = 1 To 40
        _GDIPlus_GraphicsDrawRect($hGraphics, $iLeft, $iTop, $i * 30 * $iDPI, $i * 30 * $iDPI, $hPen)
        
        _GDIPlus_GraphicsDrawString($hGraphics, $i, $iLeft + $i * 30 * $iDPI, $iTop , 'Arial', 15)
        _GDIPlus_GraphicsDrawString($hGraphics, $i, $iLeft + $i * 30 * $iDPI, $iTop + $i * 30 * $iDPI, 'Arial', 15)
Next
_GDIPlus_PenDispose($hPen)
_GDIPlus_GraphicsDispose($hGraphics)
_GDIPlus_Shutdown()
Exit

代码加入进去后：效果：

#include <GdiPlus.au3>
SetProcessDPIAware()
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') :  @DesktopWidth = ' & @DesktopWidth &@TAB &  '@DesktopHeight= ' & @DesktopHeight  & @CRLF) ;### Debug Console
Func SetProcessDPIAware()
        Local $Result = DllCall('User32.dll', 'BOOL', 'SetProcessDPIAware')
        If @error Then Return SetError(@error, 0, False)
        Return $Result[0]
EndFunc   ;==>SetProcessDPIAware

$iDPI = 2
Local $aPos_Lefttop[2] = ['100', '126']
$iLeft = $aPos_Lefttop[0] * $iDPI 
$iTop = $aPos_Lefttop[1] * $iDPI 

_GDIPlus_Startup() ;initialize GDI+
$hDC = _WinAPI_GetWindowDC(0) ; DC of entire screen (desktop)         ok!
