Question

我无法让我的Delphi（10.1 Berlin Update 2）应用程序在Windows 10（2018年4月更新）上以高DPI正确运行。整个应用程序默认情况下是模糊的（由操作系统缩放），但是如果我将DPI设置（exe的属性）更改为“应用程序”，则它的行为正确。我的可执行文件的清单文件如下：

sigcheck -m exectuable.exe

此清单用于{$R 'app.res' 'app.rc'}的DPR中，并且资源文件仅包含一行：

1 24 .\HighDPI.manifest

我不想在运行时做任何事情，但是让清单确定DPI缩放比例。谁能为我提供解决方案，以防止Windows以高DPI缩放我的应用程序？

dpiAware标记也需要xmlns属性。我使用以下清单作为模板：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
  <assemblyIdentity
    name="MyApp"
    processorArchitecture="*"
    version="1.0.0.0"
    type="win32"
  />
  <description>My Application description</description>
  <dependency>
    <dependentAssembly>
      <assemblyIdentity
        type="win32"
        name="Microsoft.Windows.Common-Controls"
        version="6.0.0.0"
        processorArchitecture="*"
        publicKeyToken="6595b64144ccf1df"
        language="*"
      />
    </dependentAssembly>
  </dependency>
  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">

      <requestedPrivileges>
        <requestedExecutionLevel
          level="asInvoker"

        />

P.S。确保升级到最新的Delphi，他们在Berlin Update 2上添加了许多HiDPI修复程序。

Answer 2

您在这里遇到的问题是Windows 10主要是读取嵌入在可执行文件而不是外部清单文件中的清单文件。

在Windows Vista及更高版本中，与Windows XP相比，嵌入的mainfest的优先级高于外部的

因此，如果您希望外部清单的属性生效，则必须从可执行文件中删除嵌入的清单文件。

Delphi应用程序的DPI不高（尽管清单看起来不错）
