Hi,

I have invoked a custom dll file into my visual studio (adding as reference). The dll contains a class that takes MWArray as input and the return type is also MWArray. I need to call that function in Visual studio. But, how do I declare MWArray type of variable?Provide me links if possible.

Thanks and Rgards,

Hi there, 

I need to insert to a DB about 6 million records.

Now; the question is which approach is best:

1. Declare and open a connection once (in the Button Click event) keep it open and keep inserting from calling a class in a mutithreaded manner ?

2. Call a class in a multihreaded manner (many threads, each thread doing Open - Insert - Close) ?

Which one will be faster and more efficient. 

Kind regards, 

Peter

We call the interface IHTMLElement, it contains the method: insertAdjacentHTML()

publicvoidTest(IHTMLElement element){IHTMLElement parent = element.parentElement;

parent.insertAdjacentHTML("beforeend",HtmlContent);}

The HtmlContent is like:

<option value="9">1                  m</option>

Then it will insert into as:
1 m
How can I resolve the problem so that to insert into as:
1               m?

PS: First, I want to use the .Replace(" ","&nbsp"), but it will replace all blank like:"<option**&nbsp**value"

How to access database on a network drive in IIS.

It works fine on my local machine.. But when I deploy code to IIS it says Cannot open database

I am experiencing a strange "memory leak" when I am using a pushbutton to start my program.  Here is a snippet:

using Kitware.VTK

               "Body of my code"

        }

     }

}

My problem is that the memory in "Body of my code" never clears until I get out of the scope of button_test_Click.  There is a loop in "Body of my code" that is supposed to re-process ~5MB of image data, but instead it seems as though the memory just adds-up each iteration. 

I know this is a problem of the pushbutton, because when I place "Body of my code" right after InitializeComponent(), within the same scope, memory does not grow.  It seems as though garbage collection does not work inside of the button_test_Click method.

Any suggestions?

I have issue setting the default printer , I need to set the default printer when I run my UWP app.

using System.Runtime.InteropServices;

[DllImport("Winspool.drv")]
private static extern bool SetDefaultPrinter(string printerName);

private static void Test()
{
    // Change the default printer to XPS Document Writer
    SetDefaultPrinter("Microsoft XPS Document Writer");
}

is not working after passing to that line , the default printer is set to my previous default printer , but in console application its working.

Thanks,

Good evening,

I know this subject has already been seen, but I didn't find any solutions to my issue. I'm trying to upload a JPG picture on my server (typical url : http://www.domain.com/upload/{idUser}) and to do that I have been using HttpClient as you can see below :

        public async Task<bool> ExecutePostPictureRequest(string endpoint, Stream stream, string name)
        {
            bool result;

            result = false;
            try
            {
                //Init client
                HttpClient client = new HttpClient();
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.ExpectContinue = true;

                //Add content
                MultipartFormDataContent content = new MultipartFormDataContent();
                content.Add(CreateFileContent(stream, name, "image/jpeg"));

                //Exec request + get response
                HttpResponseMessage message = await client.PostAsync(this.url + endpoint, content);
                this.json = await message.Content.ReadAsStringAsync();
                if (message.IsSuccessStatusCode)
                {
                    result = true;
                }
            }
            catch (Exception exception)
            {
                Debug.WriteLine("Debug - exception : " + exception.Message);
            }
            return result;
        }

Here is a private method that I use to avoid to have the fileName twice in the headers :

        private StreamContent CreateFileContent(Stream stream, string fileName, string contentType)
        {
            var fileContent = new StreamContent(stream);
            fileContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
            {
                Name = "uploadfile",
                FileName = fileName
            };
            fileContent.Headers.ContentType = new MediaTypeHeaderValue(contentType);
            return fileContent;
        }

And this is the server's logs : Bad request is me using the Httpclient and the Good request is me using a simple curl command

I tried my code, cannot get the table data, because it do not have table id and with some tricky code (I think), here is my code: 

 static void Main(string[] args)
        {
            HtmlWeb webClient = new HtmlWeb();

            HtmlAgilityPack.HtmlDocument doc = webClient.Load("http://racing.hkjc.com/racing/Info/Meeting/Results/English/Local/20161116/HV/3");
            HtmlNode table = doc.DocumentNode.SelectSingleNode("//table");


                var cells = (from cell in table.SelectNodes("./tr")
                             select cell.InnerText).ToList();

            foreach (var cell in cells)

            {
                Console.Write(cell);
                Console.ReadKey();
            }

Anyone know how to get the data from this page ? and any tricky code it using ?

Thanks a lot

Hello. I'm trying to use XmlWriter for saving my data into and it's successful but, really, I want to add(appending) more data over a time.

Example: I have created xml file, like this (thank the post: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/904a66a5-05d7-4ef1-8d07-d36d81f00f61/uwpc-read-and-write-xml-file?forum=wpdevelop)

<?xml version="1.0" encoding="utf-8"?>

<Orders>

<Order>First Order</Order>

</Orders>

----------

Then I want to load my xml for adding some similar data and see, example:

<?xml version="1.0" encoding="utf-8"?>

<Orders>

<Order>First Order</Order>

<Order>Second Order</Order>

</Orders>

----------------

 Just add, without rewrite full file

any one can discuss with a sample xml that what is the usage of namespace in xml and advantage too ?

thanks

Hello,

we have encountered a bug (most probably) in debugger of C#(.NET) VS 2015. The situation is following:

                 // continuation ....

The debugger (not runtime) bug has two demonstrations here:

1. 'month' variable is in debugger presented as value 361 thought in fact is  1 as should be.

2. progressionRow.ColB_Month property value is presented as 3770 though is 1 (program steps in into the if body)

The reason is probably related to the fact that before this code, but within in the same method there is another for loop using 'month' variable and another progressionRow declaration. The debugger shows the values from above definition.

Is there anybody who would care and fix a thing like that?

Thanks

suppose i am reading xml document using xml reader or xml textreader class but xml reader or xml textreader class has no mechanism to validate xml. so tell me how could i validate xml against a xsd using  xml reader or xml textreader class ?

is it possible at all ?

        }

        protected override void OnNavigatedFrom( NavigationEventArgs e )
        {
            navigationHelper.OnNavigatedFrom( e );
        }
    }
}

And I have child class:

using Microsoft.HockeyApp.Common;

namespace View.Chats
{
    /// <summary>
    /// An empty page that can be used on its own or navigated to within a Frame.
    /// </summary>
    public sealed partial class ChatPage : CommonPage
    {
        public ChatPage()
        {
            InitializeComponent();
        }

        protected override void NavigationHelper_LoadState( object sender, LoadStateEventArgs e )
        {
            base.NavigationHelper_LoadState( sender, e );
        }
    }
}

But I have next error in compile time:

Error CS0115 'ChatPage.NavigationHelper_LoadState(object, LoadStateEventArgs)': no suitable method found to override

Who knows how to fix it?

Please, help :)

when to use XMLReader and when to use XMLTextReader?

please tell me the difference. thanks

we have a application where we need to connect multiple database based on situation. i want to create a generic factory class where i will pass some info like <SQLLocalConnection> or <ConnectionString> and right connection string or right connection instance will be return.

string connectionString = DBConnectionFactory.GetConnectionString<ConnectionString>(Common.SQLCredentialLocal).ToString();

SqlConnection conn1 = (SqlConnection) ConnectionManager.Factory.DBConnectionFactory.GetGenericConnection<SQLLocalConnection>(ConnectionType.LocalSQLConnection);
