我知道如何阅读我的xlsx电子表格并循环浏览第一张表格.
它有5张,我遇到的不是第一张.
这是我正在使用的代码,它直接来自文档.你可以看到我试图利用setActiveSheet,但这引发了错误Call to undefined method PHPExcel::setActiveSheet().
代码:
$objReader = PHPExcel_IOFactory::createReader('Excel2007');
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load("cmt_school_data.xlsx");
//$objPHPExcel->setActiveSheet(1);
$objWorksheet = $objPHPExcel->getActiveSheet();
echo '<table border=1>' . "\n";
foreach ($objWorksheet->getRowIterator() as $row) {
echo '<tr>' . "\n";
$cellIterator = $row->getCellIterator();
// This loops all cells, even if it is not set.
// By default, only cells that are set will be iterated.
$cellIterator->setIterateOnlyExistingCells(false);
foreach ($cellIterator as $cell) {
echo '<td>' . $cell->getValue() . '</td>' . "\n";
}
echo '</tr>' . "\n"; …所以我一直在寻找,我还没有找到我想要的东西.
我有一个视图,然后是该视图的子视图.在第二个视图中,我根据我给它的坐标创建CALayers.我想能够触摸任何这些CALayers并触发一些东西.
我发现了不同的代码片段,看起来可以提供帮助,但我无法实现它们.
例如:
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { if ([touches count] == 1) { for (UITouch *touch in touches) {
CGPoint point = [touch locationInView:[touch view]]; point = [[touch view] convertPoint:point toView:nil];
CALayer *layer = [(CALayer *)self.view.layer.presentationLayer hitTest:point];
layer = layer.modelLayer; layer.opacity = 0.5;
} } }
还有......
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
// If the touch was in the placardView, bounce it back to the center
if ([touch view] == placardView) { …有人能否阐明在ASP.NET MVC应用程序的上下文中这些是如何相互比较/互补的？
它一直出现错误"在非连接套接字上不允许操作"
var ServerStream = Connect2Server.GetStream();
而且我不确定为什么
下面是该函数的其余代码
var buffersize = 0;
var Convert2Tet = new ASCIIEncoding();
var Connect2Server = new TcpClient();
var ServerEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 8801);
var ServerStream = Connect2Server.GetStream();
Console.WriteLine("Connecting to Server");
Connect2Server.Connect(ServerEndPoint);
var WelcomeMessage = new byte[4096];
ServerStream.Read(WelcomeMessage, 0, 4096);
Console.Write(Convert2Tet.GetChars(WelcomeMessage));
var UserCredentials = Console.ReadLine();
buffersize = Convert2Tet.GetByteCount(UserCredentials);
var Credentials = new byte[buffersize];
Credentials = Convert2Tet.GetBytes(UserCredentials);
ServerStream.Write(Credentials, 0, buffersize);
我正在尝试在离开页面时进行动画,但是我收到此错误:
无法解析指定对象上的TargetProperty(UIElement.RenderTransform).(CompositeTransform.TranslateX).
我从一本书中复制了代码,然后我测试了这本书的示例代码并且它可以工作,但是我无法让它在我的应用程序上工作.有任何想法吗？这是我的代码:
XAML:
<phone:PhoneApplicationPage.Resources>
<Storyboard x:Name="HidePage" Completed="HidePage_Completed">
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="phoneApplicationPage">
<EasingDoubleKeyFrame KeyTime="0" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:1" Value="-480"/>
</DoubleAnimationUsingKeyFrames>
<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateY)" Storyboard.TargetName="phoneApplicationPage">
<EasingDoubleKeyFrame KeyTime="0" Value="0"/>
<EasingDoubleKeyFrame KeyTime="0:0:1" Value="-800"/>
</DoubleAnimationUsingKeyFrames>
</Storyboard>
<phone:PhoneApplicationPage.Resources>
C#
protected override void OnNavigatingFrom(NavigatingCancelEventArgs e)
{
base.OnNavigatingFrom(e);
if (this.UriToNavigateTo == null)
{
e.Cancel = true;
UriToNavigateTo = e.Uri;
this.HidePage.Begin();
}
else
{
UriToNavigateTo = null;
}
}
谢谢!

任何想法为什么失败？
当我跑步时,git --bare fsck-objects --full我只看到悬挂的链接,但没有断开的链接.也git gc没有任何帮助.当我从另一个克隆中重新克隆或拉动时,我没有看到这个错误.
我试图弄清楚如何在执行以下要求时设置正则表达式.
基本上一个很好的例子

如果有任何帮助可以欣赏,这就是我所拥有的,但它并不像我想要的那样为我工作.

我有一个网页,其中包含一些自动生成的javascript内容,当用户点击某些链接时,它会操纵DOM.当我在Firefox中保存页面时,它只保存原始页面而不修改DOM.如何保存或转储由javascript操纵的HTML DOM 的当前状态？
我有一个mvc 3网络应用程序,但我的共享网络托管公司仅支持MVC 2.所以我也部署了mvc 3相关的dll,它在服务器上运行良好,直到它是mvc 3 beta.
昨天,我将我的电脑环境升级到mvc 3 RC并重建我的网络应用程序.该应用程序在我的本地电脑上运行良好,但当我在托管服务器上部署和运行时,它会出错.
[MissingMethodException: Method not found: 'Void System.Web.Mvc.GlobalFilterCollection.Add(System.Object)'.]
Myweb.MvcApplication.RegisterGlobalFilters(GlobalFilterCollection filters) in c:\my\Global.asax.cs:18
Myweb.MvcApplication.Application_Start() in c:\my\Global.asax.cs:36
如您所见,当我尝试在global.asax中注册全局过滤器时,它说它无法找到Mvc.GlobalFilterCollection.Add(object)方法.
如果我没有注册任何全局过滤器,整个网络在托管服务器上运行良好.
我该如何解决这个错误？
编辑:似乎mvc3 beta已在托管服务器的GAC中注册.他们说不是,但我在我的应用程序中检查了引用的System.Web.Mvc.dll的位置.
