我正在用WPF WebBrowser控件编写应用程序.它的来源是来自数据库的xml/xslt sourse的结果.
在包含的窗口中,WebBrowser有用于使用处理程序打印的按钮:
mshtml.IHTMLDocument2 doc = WBrowser.Document as mshtml.IHTMLDocument2;
doc.execCommand("Print", true, 0);

但在这种情况下,打印文档中没有背景.我已经研究过这个问题,在Internet Explorer页面设置对话框中遇到属性问题 - 允许打印背景颜色和图像.
我试图通过这段代码改变这个:
RegistryKey regKey = Registry.CurrentUser
.OpenSubKey("Software", true)
.OpenSubKey("Microsoft", true)
.OpenSubKey("Internet Explorer", true)
.OpenSubKey("PageSetup", true);
var defaultValue = regKey.GetValue("Print_Background");
regKey.SetValue("Print_Background", "yes");

但这是糟糕的代码.我不想为一个简单的bool参数更改注册表值.
所以,我的问题是:如何在没有注册表修改的情况下通过代码隐藏以编程方式更改此参数?
谢谢!
我正在尝试使用 C# 将 WrapText 属性设置为 true。
Range rng = sheet.get_Range("A:A", System.Type.Missing);
rng.EntireColumn.ColumnWidth = 50;
rng.EntireColumn.AutoFit();
rng.EntireRow.AutoFit();
rng.WrapText = true;

但它没有任何例外都不起作用。怎么了?谢谢!
我正在开发Windows Phone 7,我需要将图像添加到ListBox.
我想用C#代码,而不是XAML.
我读到了它,但每个人都使用BitmapImage,我无法在Windows Phone 7上工作.
我有XAML代码:
<StackPanel Margin="0,0,0,17">
<local:MatchDates Adress="http://soccernet.espn.go.com/results/_/league/esp.1/spanish-la-liga?cc=57393" />
</StackPanel>

和我的班级MatchDates中的C#函数:
void add_items(List<List<string>> code)
{
if (code.Count == 0)
this.Items.Add("no mathes");
else
{
foreach (List<string> temp1 in code)
{
foreach (string temp2 in temp1)
{
this.Items.Add(temp2);
}
this.Items.Add("---------------------------------");
}
}

如何在add_items函数中添加图像?
这段代码:
Uri uri = new Uri("/eng.png", UriKind.Relative);
BitmapImage bitmap = new BitmapImage(uri);
Image img = new Image();
img.Height = 30;
img.Width = 30;
img.Source = bitmap;
this.Items.Add(img);
this.Items.Add(temp2);

仅显示空白空间,如何将图像添加到ListBox?
我正在为Orchard CMS编写模块,只有在用户获得授权的情况下,才需要显示我的内容类型的所有部分.我可以在我的模块(.cshtml)中查看吗?
关于这个:
if(<statement_about_authorization>)
@T("part_1"): @Model.part_1<br />
else
@T("part_2"): @Model.part_2<br />

我正在为Orchard CMS编写模块.
