How to read Child tags under parent tag with name space in C#?
<ns:tag1></ns tag1>
<ns:tag2>
<child1></child1>
<child2></child2>
</ns:tag2>

How to read child 1 tag?
I am able to till ns:tag2 but unable to read any further tag.
var child = parentElement.Descendants(ns + "tags").First();
This provides list of child tags, but unable to further read it.
Tried a few things like:
child.Descendants("child1").First().Value
and child.Element("child1") (with all possible sub functions)
etc
Even tried to reload the xml from tag2 in XElement again but that threw invalid xml exception.
but all are throwing null pointer exceptions.

hi there,

Currently I'm trying to create, sign & broadcast bitcoin transaction using btcsuite. For start, I've already had testnet3 address & its associated privatekey for testing. However, hunting through the post and articles like below:-

https://www.thepolyglotdeveloper.com/2018/03/create-sign-bitcoin-transactions-golang/
https://github.com/prettymuchbryce/hellobitcoin/blob/master/transaction.go
https://github.com/btcsuite/btcd/issues/1164

The solution proposed above its not complete, for first one, it only covers until signing (i knew the author claimed its not broadcastable unless you provide the utxo which i did if i'm right) but when tried to braodcast it failed with message

"Error validating transaction: Transaction be9b294695bfb201a5cff32af074a4bf72b073e3c9dad1969111165bf118a622 orphaned, missing reference f0c0d3b3eecf911ede996a74ceadc9366068791450c9e6bacee9ae202f3690d1."

I have no idea what's going on and I suspect its script is incompatible.

So, the bottom line is I just want a workable example in bitcoin testnet3 that shows "from 1 address transfer some bitcoin to other address" by showing the process of creating raw transaction, sign it with private key, turn it to raw transaction in hex format & broadcast it using something like https://live.blockcypher.com/btc/pushtx/ (BTC testnet)

currently my code is as follow:-

package main
import (
    "fmt"
    "encoding/hex"
    "bytes"
    "github.com/btcsuite/btcutil"
    btcchain

I am exploring xml and am trying to write nested XML elements like this in Windows Powershell:

<r>

   <c1>

      <c2></c2>

   </c1>

</r>

I am completely new to writing XML as well as using powershell, so if you can keep the training wheels on with your explanation/example, I would greatly appreciate it.

Thanks.

Hi,

I need to write this code in global.asa. GetLastDateandTime is working fine. I need to put that in the session. If user is present then we get the data from the database. This function is working fine. If user is not present then we are using update function. My update function is not working. Page is down. I am not sure how to fix the update function.

Sub S[b]ession_OnStart[/b]

Dim objConn, objRs, strConn

Set objRs = Server.CreateObject("ADODB.Recordset")

Set objConn = Server.CreateObject("ADODB.Connection")                                                                                     

             

strConn = "test;"

 

objConn.Open strConn

dim strUser

strUser = request.servervariables("logon_user")

dim strDateAndTime = Now()       

If (strUser <> "" ) then

    Session("LastDateTime") = GetLastDateandTime(strUser, objRs,objConn)

else
[b]
   UpdateLastDateAndTime(strUser, strDateAndTime, objRs,objConn);[/b]

End If

 

Set objRs = Nothing

Set objConn = Nothing

End If

 

End Sub

 

 

Function GetLastDateandTime( ByVal strUser, ByRef objRs, ByRef objConn)

    Dim cmd

             

       Set cmd = Server.CreateObject("ADODB.Command")                            

       Set cmd.ActiveConnection = objConn

Hi Experts,

Could any one tell me what does testing a website to be compliant with WCAG 2.0 Level A and AA involve?

Are there any curses for this?

What is the going rate for this?

I'm also wondering, what are the types of assistive devices covered, so that I can recruit the right persons with disabilities (myself included ), and what to test for. The client is asking for testers with disabilities.

Thank you.

Dear Experts,

I have an asp.net website that uses identity 2.1 (I'm pretty sure > 2.0 anyways as near as I can tell). It is written in visual basic. I ran into a weird issue the other day where people were logging in and getting this viewstate error:

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

So I followed the advice I found in the microsoft article and added a machine key to the web.config file so that no matter what it (hopefully) shouldn't get that error again.

Once the machine key was changed to one that I set now we had issues with anyone with an already existant authorization cookie on their computer, they were unable to login. I believe it's because the machine key that I set no longer matched the one that was used in their cookie. I'm not entirely clear how, but apparently it's part of how it's encrypted. If they clear their cookies, all is well - then they could login.

So one bit of advice I found searching on the web sounded super simple and super-easy. They recommended that you have some sort of set key in your web.config, like a guid or something and then you add it to your cookie also. Then, when you load the cookie, you can check the key and if it doesn't match your server key, somehow you invalidate the cookie.

I basically spent all day trying to figure out …

Hi,

I was looking for some guidance on the approach to a specific user experience and how people would approach it or if someone has done something like this already.

I have a simple PHP script that enters a value from a text box into the database when the 'add' button is clicked or the user hits enter after entering a value (script below).

What I would like to do is allow a user to hit the enter key when they add their record (as it works below), but if the user were to hit the enter key again, within 4 seconds, it would bring up the full record that they could edit. It is because sometimes the user will only add the one value, but sometimes they will add the one value and also want to view and edit some other fields for that record - how would others approach this from a scripting perspective and also side topic on the User Experience side; are there better ways to do this?




$form = "<form action='./dash_hit46.php' method='post'>" .PHP_EOL;
$form .="<input type='text' id='newadd' name='newadd' placeholder='e.g. x'>" .PHP_EOL;
$form .="<input type='submit' value='add' name='add'>" .PHP_EOL;
$form .="</form>";


if ($_POST['add']){
	
	$newadd = $_POST['newadd'];
		if ($newadd){

		
		// Check connection

    die("Connection failed: " . $conn_task2->connect_error);
}

I am migrating a Magento 1 module to be used on the Magento 2 platform.  All of the code has been migrated and produces the expected results but in Magento's technical review process it fails the varnish check.Capture.PNGMy initial research into the issue shows that you should specify cachable=false on your block elements or by setting the _isScopePrivate property in your defined Block PHP file.  The only problem is that I do not have any block elements.

I have created one to try and combat this issue but the module does not require any block elements.  The module works by appending the quote results to a rateResultFactory which is then displayed on the Checkout screen.

I have also tried to use the method described here to try and retrieve any dynamic data without requiring the cacheable flag.

Any help would be tremendously appreciated.

I had this question after viewing Auto refresh webpage but maintain scroll position.

I love the assisted solution, but when using a .mht file it does not work.
Internet Explorer asks if I want to open the file and the mht file opens in a new window.

How can I open, refresh (and stay on scroll) of an excel generated mht file?

Cannot request a new account in WkikMedia

Please look at chaliceuucongregation.org, then click "Chalice Wiki" (last item on the menu).

On the right sidebar, click "Request an Account", goes to "Get an Account" page. Click Request an Account, loops back to the prior page.

Used to work, we moved hosts, not sure if it has worked since then.

Any ideas on how to address this?

Thanks

After upgrading to Windows 10, my local Development Copy of the code using my local IIS Express Version 10 is unable to get the current HttpContext.  The same code

I need to integrate Apple Pays decrypted Payment Token Format into a Stripe Rest API call. This does not require any Stripe SDK's or JS files. The raw apple pay token information has already been decrypted ready for stripe to process via 'Source', 'Token', 'Charge' etc. Stripe support will not disclose the solution but acknowledge its possible, why, i am not sure? Spreedly does exactly as i am describing with Stripe, passing in the information below, but how is it correctly structured?

This is the what a decrypted Apple Pay payment token format looks like:

{"applicationPrimaryAccountNumber":"4xxxxxxxxxxxxxxx","applicationExpirationDate":"211130","currencyCode":"840","transactionAmount":1000,"deviceManufacturerIdentifier":"000000000000","paymentDataType":"3DSecure","paymentData":{"onlinePaymentCryptogram":"/random+stuff=","eciIndicator":"7"}}

Good afternoon everybody. I wonder if you can advise me on the following, or signpost me to any resources that might help ?

I'm trying to create a Norwegian website (don't ask). However, it doesn't seem to like 'special' characters in links.
For example, I have a page called "transportører.php".

On another page, I have a link to it.. hence
<a href="transportører.php">Link Text</a>

Open in new window

.

All well and good. But when I CLICK on that link, it attempts to go to a (non-existent) page called "transportører.php".
Clearly, the text "transportører" is being mangled during the lookup process. The ø character is being mutated into 'ø' (an A with a tilde, followed by a comma).

Any thoughts on what I am doing wrong ? Why can't I have a link called "transportører.php". (a similar phenomena occurs with all other "special" Norwegian characters with diacretics).

I know that the host component of the URL is shielded by Punycode, but this doesn't seem to work with the file-path part.

Yours in perplexity,
Nic
