My whole project framework is 4.0.May be the System.Net.Http.dll is 4.5.

I use this httpclient,and it actually has HttpClient.PostAsync() function.
#region System.Net.Http.dll, v2.0.0.0
// C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Assemblies\System.Net.Http.dll
#endregion

using System;
using System.Net.Http.Headers;
using System.Threading;
using System.Threading.Tasks;

namespace System.Net.Http
{
// Provides a base class for sending HTTP requests and receiving HTTP responses
// from a resource identified by a URI.
public class HttpClient : HttpMessageInvoker

It seems nothing has changed

Hi,I use the center tag,but the result is like removing removing the "Float: Left;" .But I want that firstly the toydiv is in the left,and the button is in the right,and secondly the button is in the center of vertical in the right.Could you give me a sample?

If I remove,the btton is in the bottom of the toydiv.I want that firstly the toydiv is in the left,and the button is in the right,and secondly the button is in the center of vertical in the right.

If my project have more than 10 models,means that I have to prepaire more than 10 views.It seems unrealistic,especially when I want to add a new model type to database but the site been published without this new model view.

It is shown in the same view but the view's content is different according to the return model's attribute of the controller.The requirement just like this, int the view left page,I show student,Fruit,and other model's name,when I click the student model name,in the view right page,it show the student model's attribute detail and I can also update the student student model's attribute value .when I click the Fruit model name,in the view right page,it show the Fruit model's attribute detail and I can also update the Fruit model's attribute value .

Thank you,but I'm afraid that this way may not be suitable for me.Because I have more than ten objectmodels in my project!My boss say that I can use key and value like dictionary<string,string> this way,and cycle of the output of the model attribute but I do not know how to start it.

Thank you, when user use IE10 to view my web,you say these statements will not work ,but in fact in IE10 my scripts also work,I think because of '<!-->'.

Can you show me how to convert the Date in to UTC date before return to JSON? Now I read the birhday from database directly and return to JSON.I check my database,the birthday value like '2013-05-28 00:31:00.000',it seems not like the utc format.If my server time is not utc format, I want to change to time rely on clinet web brower,is it OK?For example,the server is in Beijing(utc+8),If I in utc+8 timezone,I get the data and add 8 hours,If I in utc+7 timezone,I get the data and add 7 hours.And another question,If the web server is in Utc+9 timezone like Tokyo,and I am in utc+7 timezone,am I also add 7 hours or 9 hours?As far as I know ,my database's birthday is not utc format and my web server is in Beijing(utc+8),and I am also in Beijing, ervery time I add the birthday from the server Json,I add the timezone(means 8 hours) manually,it runs well!

like this: http://jsfiddle.net/maertz/qf5m3/,the img's url is so long

I change to return JSon(File(str, "attachment;filename=" + "TempFile.xls"},JsonRequestBehavior.AllowGet );
but still fail: it did not Pop-up a window.

data["Jhon"].Grade is wrong,I have try again,may be I should use other library.

data["Jhon"].Grade is wrong,I have try again,may be I should use other library.

Thank you very much,it works well.Can I ask the last question?You say LineAnnotation which does not display the text,then where is
LineAnnotation used in mainly?

Do you have run the code?I run,but it still do not work.This is the result:https://www.yousendit.com/download/UW13blR1Z2pWRC80WjlVag

Thank you! I have change the type,but it still does not work.Can you give me a example??

I have do this in the code up at line four,but it do not work
chart1.Series.ElementAt(0).ChartType = System.Windows.Forms.DataVisualization.Charting.SeriesChartType.Point;

Usually in windows 2008 r2 box,does the port 25 is default to opened automatically?
Did I need to add port 25 in firewall to open manually or it is default to opend by the system?I using c# code,it seems I do not need to install smtp server in my system!!!

StatusCode: GeneralFailure
Message: 在 System.Net.Mail.SmtpClient.Send(MailMessage message)
StackTrace: 在 AutoMail()(My method code is up,and the name is AutoMail)
Do win2008 R2 need to configurate something when send mail???

Can you tell me why is 512? Thank you!

Some one say that the limit is 256, because of 8 bit and 2^8=256

If I use tooltip,when I move to the chart and no drag the point ,It is OK!
But when I move to the chart and no drag the point ,It shows nothing!

Thank you for answert.I didn't solve the first question,and think the second question have some connection with it.

OK,I will try, the config file make it difficult.By the way,do you know how to send a mail attacted with a file like txt,word,png?

Export is now OK,but the import web I can not open it!!

Thank you.It is export,I am reading now.

Both, I think we can optimize this.

I have reference the dll,but I　did not find the control.Can you tell me where to find it?

enen,Thank you very much!

Ok,Thank you! May I ask whick Tag should I mark?

Thank you,I find a bug in the software,when export time ,it seems wrong

OK，I have edited again,Thank you!

I will try it,Thank you very much!

In silverlight，it have not Graphics and TextureBrush class.I dont know how to do that

user input a string, and then click the button,it shows the string that using the font which is choosen by user!(new Font(font, fontSize)) ,user can set the font and fontsize

in this web http://technoblizzard.blogspot.in/2007/09/tree-view-in-dropdownlist.html,can I directly set the datasource of dropdownlist to be treeview?

I have export other data column,but lack of the picture column

Thank you,I am looking at the codes which you provide.

if ((e.Item.ItemType == ListItemType.Item) | | (e.Item.ItemType == ListItemType.AlternatingItem))，here ListItemType.Item means all the item,and I think (e.Item.ItemType == ListItemType.AlternatingItem) is redundant,is that right?

I have show my code,but still have exception.
//debugs Exception,Array bounds because reclength=1024*1024*2;
Buffer.BlockCopy(arr, 0, receiveBytes,recLength,arr.Length );

Dear John Simmons,Is your code like this:
byte[] receiveBytes= new Byte[1024 * 1024 * 2]; byte[] arr=new byte[1024*5]; Buffer.BlockCopy(receiveUDPClient.Receive(ref remote), 0, receiveBytes, 0, receiveUDPClient.Receive(ref remote).Length); int recLength = receiveBytes.Length;//debug says recLength=1024*2*1024

1.if arr is initializied,it must have a certain size?(You say instead of it?)
2. arr.Length should have the size of the buffer being copied.
Is there a conflict between 1 and 2?

if it doesn't exist will be ignored. This is the answer.
At first,I think if it doesn't exist,it will create it automatically.
Thank you ,OriginalGriff!

when I use "sfd.AutoUpgradeEnabled = true;" ,it show in a defualt path(not d:\temp);when I use "sfd.AutoUpgradeEnabled = false;" it show in the current app directory;It seems that sfd.InitialDirectory = @"d:\temp"; doesn't do anyting!!!

Hello. Is there any number of businesses are using or have already released a Web site? I had sql server example,thank you anyway。Any shop or bank using reporting service?

Thank you.I was reading this carefully

Thank you!It is not a test,it is a practise from a book without answer,I do not know whether it is right or not.

I have try to fix it many times ,but I can not do it. <img src="http://hi.csdn.net/attachment/201111/3/3652857_1320325279YaZf.jpg" alt="picture"/>Can you tell me how to upload a picture to this websit?Thank you!

En，Thank you very much.You way is better than the direct calculation.

Thank you.May be we do not have to calculate the result.

BigInteger answer = BigInteger.Pow(449, 524);
Console.WriteLine(answer.ToString());
Console.WriteLine(answer.ToString().Substring(answer.ToString().Length-4, 4));
Thank you!

Thank you all. In the beginning I thought there may be a simple algorithm to solve,and we do not have to calculate the result.Bobjanova's solution is firstly calculate the result.

No,it just an interview question,it ask me to make codes to solve it

Oh my god,is it wrong?

Thank you!I'm curious about this stuff,May be it is used by API

using System.Numerics.BitInteger (only available in the .NET Framework v.4)？？Does it provide ready-made class?
Maybe we can write a class,but I think is not simple

Thank you.No,I just wonder how they do that

I find this way,but not RSA.
System.Security.Cryptography.RandomNumberGenerator gen = System.Security.Cryptography.RandomNumberGenerator.Create();
byte[] data = new byte[100];
gen.GetBytes(data);
