Error: the type or namespace name does not exist in the namespace using visual studio 2017

When compiling an error will occur that a name space does not exist. An example error like the message below:
The type or namespace name 'Microsoft.Office.Interop.Outlook' does not exist in the namespace 'Microsoft'(are you missing an assembly reference?)
The system is trying to find a reference for a specific namespace or dll.
One solution for this is to add the reference to the missing namespace.
Find the “solution explorer” window like the image below:


After opening the “solution explorer” window, right click the name of the project just below the solution explorer. Beside the C# icon.
A new window will open like the image below. Click “Add”, then click “Reference”.



After clicking “Reference”, the “Reference Manager” window will open.
Click “COM” option, then use the filter option to go directly to the desired namespace or reference. Since the error is a Microsoft namespace, type “Microsoft” and “Microsoft” namespace will be filtered from the list. See image below…

PowerShell Insert Multiple Lines or text to another file dynamically

Copying and pasting text to another file is a common thing to do, copy and paste done. Boom!
In PowerShell scripting copying and pasting text from one file to another dynamically isn’t as easy as it is done in a spreadsheet or document. Dynamically while the code is running  and doing things in the background without human intervention.
As the odds say, if there’s a will there’s a way. And making things efficient and easy is a good way in life.
If ever a scenario occurs that you need to copy text or lines in a file from one file to another, without breaking the code execution. Script below works just fine. Just insert the code where it is needed.

PowerShell code snippet:
#================================
$reader=[System.IO.File]::OpenText("D:\test-read-paste\main1.txt") #get-content can also be used
$lineNumberx=3 #adjust this number where you need to start inserting the text
#Loop line by line and process while($null-ne ($line=$reader.ReadLine())) {
$textToAdd=$line
$newLineToAd…

PowerShell repeat spaces or characters

Example code of repeatingspaces within a string:
$xrepeat = ' ' * 11 $string_with_spaces = “ Hello World of Spaces!!!”
Write-output $xrepeat $string_with_spaces
Output image:

To indent or tab a string:
$Tab = [char]9 Write-Output "$Tab Hello Tab Indention!!!"
Output image:

To add other HTML character in PowerShell string:
$Euro_symbol = [char]8364 Write-Output "$Euro_symbol Hello Euro Symbol in PowerShell!!!"
Output image:

Loop thru custom Textboxes name in VBA or VB.Net

Having a custom name in Textboxes, Listbox, ComboBox in VBA or VB.Net is a good strategy. So, it will be easy to debug the code or analyze the data.

If just relying on the default names is also good but it will get messy and it will be hard to control when there’s quite a few of textboxes, and list boxes. And the next person who will maintain the code will find it easier to debug or check the program when proper custom name is assigned to the controls. And that next person might be yourself. So, be gentle and be explicit in giving comments and assigning names to controls.

It doesn’t hurt to put a clear comment or an overview of what the piece of code does or what’s the input that the control is accepting. Because greediness breeds greediness, and it will bite back.

Anyway, to loop to all the custom or default names is quite easy.


Example, if there are 30 or more textboxes in a form. It can be done by a simple for loop like:

For x = 1 to 30

GetTboxvalue =    Me.Controls(“Textbox” & …

PowerShell get folder capacity

Get the folder capacity using PowerShell via the old-school method.
Old-school since we will utilize the native “dir” command, just like the good old days of DOS.
PowerShell dir command output is not the same with the native windows system32 dir command line just like in DOS system.
The output will be in bytes since it is from the command line but of course, if you are command line junkie it will be easy to read even if the capacity is written in bytes.
First, fire up notepad write the dir command plus the full folder path of the specified folder in which you like to monitor or want to know the capacity.
 dir “c:\users\dmusic\music folder 001”
The path is enclosed in quotes since the folder has spaces and save the notepad as a batch file with “.bat” extension.
Open PowerShell command line window or PowerShell ISE and type the following command:
#change the path to where the batch file was saved
$folder_base_cap = d:\read_folder_cap.bat 
$ folder_base_cap | Select-String "bytes&qu…

Sort numbers, digits or figures in Excel 2016

To sort numbers, digits, or figures in Excel 2016 is quite straight forward.
There are two ways to do it via the Home tab or Data tab.
What is found on the Home tab is sorting of alphabets or A-Z option which can easily be seen beside the auto-sum function which is on the right most tab of the ribbon by default.
Screen shot below shows the sorting functionality found in Home tab.


The other way to sort by numbers, digits or figures in Excel 2016 is to click on “Data” click on “Sort” then an option will appear to sort by smallest to largest or largest to smallest.
A screen shot below shows where to find the function.


That’s it hopes it helps to make thing easier.

PowerShell disable USB ports

Disabling USB ports using PowerShell by modifying registry values.
How to user PowerShell to modify an existing value in Windows Registry?
PowerShell code below modifies the registry value and disable USB ports in Windows.
The code must be run in an elevated mode to modify the registry.
Here's the code:
Modify the registry key value using PowerShell:
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\USBSTOR\" -Name "start" -Value 4
To enable the USB ports, change the value to 3:
Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\USBSTOR\" -Name "start" -Value 3
Disabling USB ports is quite annoying of course, but if security is a concern then I guess it is justifiable especially computers that can easily be accessed by unwanted guests or individuals.

It will also protect the network or computers from getting malware's or viruses that is transferred or copied via USB storage.



Cheers! Till next time.

PowerShell validate list of email addresses

Validate list of email addresses in a text file and check which email is a valid email and which one has the incorrect format.
PowerShell code below can easily check or validate incorrect email, output will show true if valid email and false if the email is not valid.
To check list of valid emails PowerShell utilizes regex. This is useful to check typo errors when sending out mass email or a list of emails which has not yet been verified.

But of course, the code will not be able to check whether the emails are active or not.

#===============================
$reader = [System.IO.File]::OpenText("c:\all_emails.txt") #get-content can also be used
#read the file line by line and validate the data
while($null -ne ($line = $reader.ReadLine())) {
    #$line     $regx="[a-z0-9!#\$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#\$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"

How to escape in PowerShell

In bash script the backslash is use as escape sequence and even in Java programming.

But what's the equivalent of bash escape sequence in PowerShell?

Grave accent or back tick, which is found at the top left corner of the keybord below the "esc" key on some keyboard, This character "`" is the escape in PowerShell.

For example:

Write-host "This line is above `r`n and  `r`n this line is below"

Output is:
This line is above
 and
 this line is below

r is equal to carriage return character putting a backtick before r, `r tells PowerShell that r is not a character but a carriage return
n is a new line character putting a backtick before n, `n tells PowerShell that n is a new line character.

Another example:

$ sign in PowerShell is to indicate a variable

But what if you need to display a dollar sign as a character and not as a special character to declare a variable. Then we need to escape the dollar sign by prefixing a backtick before the character.
