C# System.Windows.Forms.WebBrowser控件是否支持DPI?
如何使System.Windows.Forms.WebBrowser控件使用de DPI_AWARE标志来显示支持DPI的文档?如果有人能发布代码示例,将不胜感激 编辑1:添加更多详细信息 问题在于,px单元被视为普通像素单元(而不是像web一样),因此在150%dpi配置下的大小差别很大,在更高的dpi设置下甚至更大。WebBrowser。版本是11.xC# System.Windows.Forms.WebBrowser控件是否支持DPI?,c#,winforms,webbrowser-control,C#,Winforms,Webbrowser Control,如何使System.Windows.Forms.WebBrowser控件使用de DPI_AWARE标志来显示支持DPI的文档?如果有人能发布代码示例,将不胜感激 编辑1:添加更多详细信息 问题在于,px单元被视为普通像素单元(而不是像web一样),因此在150%dpi配置下的大小差别很大,在更高的dpi设置下甚至更大。WebBrowser。版本是11.x class myWebBrowser: System.Windows.Forms.WebBrowser, IDocHostUIHandler

ICustomDoc doc = this.Document.DomDocument as ICustomDoc;
if (doc != null)
{
\\code reaches this point
doc.SetUIHandler(this);
}
}
uint GetHostInfo(ref DOCHOSTUIINFO info)
{
info.dwFlags = (int)flags;
info.dwDoubleClick = 0;
return S_OK;
}
\\other IDocHostUIHandler methods...
}
此处定义了接口:
[ComImport, Guid("3050F3F0-98B5-11CF-BB82-00AA00BDCE0B"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
internal interface ICustomDoc
{
[PreserveSig]
int SetUIHandler(IDocHostUIHandler pUIHandler);
}
[ComImport, Guid("BD3F23C0-D43E-11CF-893B-00AA00BDCE1A"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
internal interface IDocHostUIHandler
{
[PreserveSig]
uint ShowContextMenu(int dwID, POINT pt, [MarshalAs(UnmanagedType.Interface)] object pcmdtReserved, [MarshalAs(UnmanagedType.Interface)] object pdispReserved);
[PreserveSig]
uint GetHostInfo(ref DOCHOSTUIINFO info);
[PreserveSig]
uint ShowUI(int dwID, [MarshalAs(UnmanagedType.Interface)] object activeObject, [MarshalAs(UnmanagedType.Interface)] object commandTarget, [MarshalAs(UnmanagedType.Interface)] object frame, [MarshalAs(UnmanagedType.Interface)] object doc);
\\etc.
}
[StructLayout(LayoutKind.Sequential)]
internal struct DOCHOSTUIINFO
{
public int cbSize;
public int dwFlags;
public int dwDoubleClick;
public IntPtr dwReserved1;
public IntPtr dwReserved2;
}
你试过什么?如果您能发布一个代码示例,我们将不胜感激。对于缺少信息,我们深表歉意。我添加了一个例子,你还需要这个吗?我切换到了CefSharp(铬的C#包装)
