Question

在Visual Studio 2017中，已添加了“ DPI感知”功能。通过以下命令填充数据表时：

    Dim dt As DataTable = New DataTable
    da.Fill(dt) <---- This is the line where the rescaling occurs

在上面的行中，窗体将自身重新缩放为较小的尺寸，以匹配监视器在Windows中为其scale属性设置的内容。我该如何预防？我不希望表单重新缩放并更改大小，而只是保持原样。

注意：我知道您可以在“不知道DPI”状态下重新启动Visual Studio，但是即使在这种状态下，运行应用程序时也会发生上述问题。

这是解决此问题的方法：

在Visual Studio中，右键单击您的项目> Add> New Item..
从选项中选择Application.Manifest File。保留默认名称app.manifest。点击Add。这将为您的项目生成清单。（注意：默认情况下，您的应用程序不包括清单文件。
打开新创建的清单文件。一切都应该已经填充。取消注释此部分（通过删除之前的）

<application xmlns="urn:schemas-microsoft-com:asm.v3"> <windowsSettings> <dpiAware xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">false</dpiAware> </windowsSettings> </application>

保存清单文件并进行编译。您的表格将不再重新缩放。
