2. if necessary, remove scroll bars.

Thank you,

Hi guys

I have an excel sheet with a load of data in one particular column. It has lots of email addresses ending with various domain names. In the next column, I would like to create some sort of formula that outputs the domain names from the column with the data into the associating rows so that I can then organise it by domain name. So if cell A1 says 'lisa@abc.com i would like the next column in the associating row to output 'abc.com' and then do that for all the domain names in there.

Does this make sense? If so, can you help me write the correct formula to output the content correctly?

Thanks a lot

Merge 2 Excel 2016 Files to single file and group records

I have 2 files, each with 4 columns:

Email Address - First Name - Last Name - Type

My goal is to merge these files so that records with same Last Name values will be grouped in the new file, that is the records will be grouped - sorting of fields not necessary.

How do I do this?

In the given sample in sheet-1 there is a column called skill where filter is applied.
What I need to do is apply filter for each skillset and then count the frequency of numbers under the column baseline level and then place the frequency of each number into sheet-2 under L1,L2,L3 of the current level.
for eg-
in sheet 1 filter the skills column by lets say, the skill "Angular JS".
Therefore, now the baseline level column contains only entries i.e 0 and 1. So count the occurences of 0s and then in Sheet-2 look for the row with the entry Angular JS. After that fill L1 (current level) with 1 (as 0 only occurred once) and L2 with 1(as 1 has occurred only once).

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 

Open in new window

On the sample file attached I have data arranged in columns A thru E on Sheet1.  The column E with field name "Deletion Check" is used to check the status of each row for deletion, if it says "Delete" then that row should be deleted in its entirety. I tried three different VBA procedures and those can be seen in modules to achieve the deletion of all those rows that meet the criteria but all procedures raised error.

On Sheet2 I placed the original sample data so after testing the code data set can be reverted back to its original state again.  One quick note here is that initially I was using the procedure "deleteRowswithSelectedText() " without any issues, the way I was using this code from the button was that I was highlighting the column E then running it and it was working pretty good up until this morning but for reasons that are beyond me it stopped working and after that any other code trial generated error even after I tried on brand new files.  

So if any expert can offer a working code either by modifying one of the existing code blocks or adding entirely new code would be much appreciated.

The Firewall Audit Checklist
The Firewall Audit Checklist

Preparing for a firewall audit today is almost impossible.
AlgoSec, together with some of the largest global organizations and auditors, has created a checklist to follow when preparing for your firewall audit. Simplify risk mitigation while staying compliant all of the time!

web applications vs. custom desktop software.  These are the two scenarios that I am posed with in designing an attendance/registration system for our organization.  Are there disadvantages to web application vs. a desktop software.  I imagine there is more power in the coding aspect of most programs compared to web application development.  I know its an abstract question, but I wanted to see what the experts have to say on this subject.   Is there really no difference?  The application I will need to design will register individuals, take their daily attendance, and then output statistics.  Also any ideas on how to best develop such a program may be appreciate.

Hello Community,

I'm absolutely new on programming and I want to learn Delphi as my main and solid first choice.
Searching on Google I did not find any interesting resource about how can I start programming on Delphi (or not just with updated content). I want to know about learning sites, learning video courses, ebooks and all of them completely easy to follow and readable.

Please, I hope that someone can help me with my request.
Also, Are there any free version of Delphi to start programming with?. And the result of the created apps with this IDE can be used for business?.

Regards,

Dear @Shums,
This is additional requirement for my previous question (https://www.experts-exchange.com/questions/29107816/VBA-for-inserting-and-deletion-of-new-columns.html) which you helped me.

REquirement : For all the weeks which we insert, the total column should have the sum of the values below it.

For e.g. IF we insert 2 weeks , then if the value of Week1 is 2 and Week2 is 1 then the sum should be 3.

Similarly, if we insert 3 weeks, then if the value of Week1 is 2 , Week2 is 3 and Week3 is 1 then the sum should be 6.

The sum formula should not get changed once we change the number of weeks.

I have attached the scenarios in sheet 2.
