小编Sag*_*tri的帖子

我正在尝试将icalendar发送给用户,以便他们可以在Outlook中打开这些ics文件并保存约会.我正在使用的邮件是'phpmailer.php'.

问题是它在邮件正文中将hical格式发送为html.这是我的代码

$text="
BEGIN:VCALENDAR
VERSION:1.0
BEGIN:VEVENT
CATEGORIES:MEETING
STATUS:TENTATIVE
DTSTART:".$startDateTime."
DTEND:".$endDateTime."
SUMMARY:Interview for the candidate".$cname."
DESCRIPTION:".$message."
CLASS:PRIVATE
END:VEVENT
END:VCALENDAR";

$mail->SetFrom('xxxxxx@yahoo.com', 'xxxx');
$mail->IsSMTP();
$mail->Host = "smtp.mail.yahoo.com";

$mail->SMTPAuth = true;
$mail->Username = 'xxxxxxxx@yahoo.com';
$mail->Password = 'xxxxx';


$mail->AddAddress($addresses[$i]);
$mail->Subject    = "Interview schedule of Candidate";

    $headers = "From: Sender\n";
        $headers .= "Reply-To: xxxxxx@yahoo.com\n";
        $headers .= "MIME-Version: 1.0\n";
        $headers .= "Content-Type: text/calendar; method=REQUEST; charset=utf-8\n";
        $headers .= "Content-Transfer-Encoding: 8bit\n";
        $headers .= "Content-class: urn:content-classes:calendarmessage\n";
$mail->Body=$body;

if(!$mail->Send($headers,$body)) 
{
        echo …

我正在尝试处理价值变化,所以我可以进行计算

    private void supplierDiscountPercetangeSpinEdit_EditValueChanging(object sender, DevExpress.XtraEditors.Controls.ChangingEventArgs e)
    {
        decimal price, percentage, calculatedPrice;

        price = (decimal)supplierPriceSpinEdit.EditValue;
        percentage = Convert.ToDecimal(e.NewValue);  // breakpoint 1
        calculatedPrice = Popust.Izracunaj(price, percentage); // breakpoint 2

        supplierPriceWithDiscountSpinEdit.EditValue = calculatedPrice;
    }

在Breakpoint 1 e.NewValue是object {string} "1.00"

在Breakpoint 2 percentage是object {decimal} 100

它必须是 1.00M

我怎样才能转换e.NewValue为十进制？

我只是将C#函数转换为VB.NET函数,但不知怎的,我得到了一些错误.下面是我的C#函数.

public abstract class BaseFilterControl: UserControl,IFilterControl
{
    public string PropertyName { get; set; }

    public FilterDescriptorBase AssociatedDescriptor { get; set; }

    public bool IsFirst { get; set; }

    public abstract FilterDescriptorBase BuildDescriptor();

    protected abstract void Initialize();
}

下面是我目前的VB功能

Public MustInherit Class BaseFilterControl
    Inherits UserControl
    Implements IFilterControl

    Public Property PropertyName As String

    Public Property AssociatedDescriptor As FilterDescriptorBase

    Public Property IsFirst As Boolean

    Public MustOverride Function BuildDescriptor() As FilterDescriptorBase

    Protected MustOverride Sub Initialize()
End Class

我收到了这个错误:

BaseFilterControl must implement Function BuildDescriptor() As …

vector<Point> points;
findNonZero(bin, points);
RotatedRect r = minAreaRect(points);

我转换成:

MatOfPoint2f points=new MatOfPoint2f();
Core.findNonZero(bin, points);     //// findNonZero returns Mat but i have provided MatOfPoint2f
RotatedRect r = Imgproc.minAreaRect( points);

我收到以下错误:

我试图更新数据库中的记录使用Object.update_attributes(:field => "parameter") 以显示我试图做的一个简单示例.请参阅下面的代码

a = params["ORDERNO"].to_s
b =  params["TRACKNO"].to_s    
@bd=Staging.where(:trackno => b , :orderno=> a)
    if @bd.nil? 
       puts "not found"
    else
       @bd.update_attributes(:field_name => "PARAMETER")
    end

我也试过了 @bd.first.update_attributes(::field_name => "PARAMETER")

我将XML输出存储到String和再次将此字符串转换为XML.我成功将XML输出转换为String,但我再次遇到问题将字符串转换为XML.

示例代码:

 webservice.Service1 objService1 = new webservice.Service1();
    String s = objService1.HelloWorld();   //Convert XML output into String   
    XmlDocument xd = new XmlDocument();
    xd.LoadXML(s);

我使用LoadXML()方法,但我得到了错误

Data at the root level is invalid. Line 1 position 1.

感谢,如果有任何正文提供正确的代码,在c#中将String转换为XML.谢谢,

我的查询tinyint(1)从 mysql 中的表中获取字段，如下所示

mysqlcommand.selectquery="select vehicletype from vehicles where id=1"

可能的值为vehicletype1 到 7

但该datatable字段行中的输出显示为boolean

datatable dtresult;
mda.Fill(dtResult);
DataRow dr = dtResult.Rows[0];
//dr["vehicletype "]=false if 0
//dr["vehicletype "]=true if 1
//dr["vehicletype "]=true if 2
//dr["vehicletype "]=true if 3
//dr["vehicletype "]=true if 4 etc...

当我dr["vehicletype "]在 Visual Studio 中看到 的值时，它显示false为 0 和true任何其他值。如何防止它进行默认转换

在 C# 中reset点击WaitOne();of后是否需要调用清除多个集合AutoResetEvent？

我写了一个ac#program,并将它与文件扩展名相关联,就像DOC没有安装MS-Office的PC 一样.然后,我双击任何名称包含空白字符的文件,我的程序将启动以打开该文件.我用下面的声明:

string[] args = Environment.GetCommandLineArgs();

然后args[1]将包含该文件的完整路径文件名.然后,我可以打开它.但现在的问题是,如果文件名包含空白字符,则args[1]包含的文件名与实际文件名不同.作为标题,如果我的文件在e:\tmp3,文件名是test uesr=doc.doc,我期望args[1]包含

"e:\tmp3\test user-doc.doc",

但它实际上包含

"E:\tmp3\TESTUS~1.DOC"

谁能告诉我为什么以及如何解决它？谢谢.

我正在编写java桌面应用程序.我有一些textareas来从用户那里获取数据.A JButton,它接受输入和处理.并且a JTable填充处理的数据.

这是我从main调用的构造函数.

    public ChangeButtonLabel()
    {
        JFrame f=new JFrame();
            f.setLayout(null);

        JLabel lab1=new JLabel("Name");
            JLabel lab2=new JLabel("Age");

        //table=new JTable(model);

        text1=new JTextField(20);
            text2=new JTextField(20);


        button=new JButton("OK");

            lab1.setBounds(10,10,100,20);
            text1.setBounds(120,10,100,20);

            lab2.setBounds(10,40,100,20);
            text2.setBounds(120,40,100,20);

            Table=new ArrayList();
        Table.add(new ArrayList());
        ((ArrayList)Table.get(0)).add("\nProgram Name   ");
        ((ArrayList)Table.get(0)).add("Count   ");
        ((ArrayList)Table.get(0)).add("Elapsed Time   ");
        ((ArrayList)Table.get(0)).add("Average ET\n");

        button.setBounds(120, 100, 100, 20);        

        button.addActionListener(new MyAction());

            Object[][] data = {
                {"Program Name","count","ET","Avg ET"}
            };


        model = new DefaultTableModel(data,columnNames);

            dataTable = new JTable(model);

            dataTable.setPreferredScrollableViewportSize(new Dimension(500, 70));
            dataTable.setFillsViewportHeight(true);

        dataTable.setBounds(220,130,300,200);
            f.add(lab1);
            f.add(text1);
            f.add(lab2);
            f.add(text2);

        f.add(dataTable);

        f.add(button);

            f.setVisible(true);
            f.setSize(300,350); …
