SharePoint 2013 --- I'm Back

Wow, back at developing in SharePoint, who knew... Well my new co-working SharePoint Kerry, gave me some insight on SharePoint Application Permissions DUH! I an knocking the cobwebs out of my head using SharePoint Again. Central Admin > Application Management > Select the "App" > On the ribbon User Policy --- *DUH*! Adding or updating Web application policy with new users or groups will trigger a SharePoint Search crawl over all content covered by that policy. This can reduce search crawl freshness and increase crawl load. Consider using security groups at the policy level and add/remove users from security groups to avoid this.

Just switched over to Visual Studio Professional 2017 and it rocks!!!

JavaScript Refresh Time

There are 7 basic types in JavaScript. number for numbers of any kind: integer or floating-point. string for strings. A string may have one more more characters, there’s no separate single-character type. boolean for true/false. null for unknown values – a standalone type that has a single value null. undefined for unassigned values – a standalone type that has a single value undefined. object for more complex data structures. symbol for unique identifiers. The typeof operator allows to see which type is stored in the variable. Two forms: typeof x or typeof(x). Returns a string with the name of the type, like "string". For null returns "object" – that’s the error in the language, it’s not an object in fact. In the next chapters we’ll concentrate on primitive values and once we’re familiar with that, then we’ll move on to objects. New great online tool - http://plnkr.co/ Also Must READ!!!!

How to catch an error and send via email and log to the server (aka simple text file not event log). (VB.NET)

Catch ex As Exception
            'Log to exception table
            Dim strError As String
            strError = Now().ToString() & "Error: (Class=PromoCode;Method=IsEmailRequired)" &
                       ";" & vbCrLf & "PromoId = " & promoCodeId &
                       ";" & vbCrLf & vbCrLf & "Exception " & ex.ToString()

            MiscFunctions.SendExceptionEmail(strError)
            MiscFunctions.WriteLogRecord(strError)

            myPromoCode = Nothing
            Return myPromoCode
        End Try



 '---------------------------------------------------------------------------
    'Description: Email Exception Error
    '---------------------------------------------------------------------------
    Public Shared Sub SendExceptionEmail(ByVal errorException As String)

        Dim myMail As New MailMessage()

        myMail.From = New MailAddress("error@domain.com")
        myMail.Subject = ConfigurationManager.AppSettings("CoreHTTPPath") & " error exception"

        'Create an email from the email addresses in the app.config file
        Dim emailTo As String = System.Configuration.ConfigurationManager.AppSettings("AdminEmails").ToString()
        Dim strEmailArray() As String

        strEmailArray = Split(emailTo, ";")

        For Each email As String In strEmailArray
            myMail.[To].Add(email)
        Next


        Dim sb As New StringBuilder()
        sb.Append("www.domain.com error exception: " & vbCrLf & vbCrLf)

        sb.Append(errorException)


        Dim strBody As String = sb.ToString()
        myMail.Body = strBody

        myMail.IsBodyHtml = False

        Dim smtp As New SmtpClient()


        Try
            smtp.Send(myMail)
            myMail = Nothing
        Catch ex As System.Exception
            WriteLogRecord(Now().ToString() & " Error: (Function Sending errorException) " & ex.ToString)
        End Try

    End Sub

    Public Shared Sub WriteLogRecord(ByVal strErroMsg As String)

        Dim objWrite As IO.StreamWriter

Regular Expressions

To match a string that contains only those characters (or an empty string), try

"^[a-zA-Z0-9_]*$"

This works for .NET regular expressions, and probably a lot of other languages as well.

Breaking it down:

^ : start of string
[ : beginning of character group
a-z : any lowercase letter
A-Z : any uppercase letter
0-9 : any digit
_ : underscore
] : end of character group
* : zero or more of the given characters
$ : end of string

If you don't want to allow empty strings, use + instead of *.

EDIT As others have pointed out, some regex languages have a shorthand form for [a-zA-Z0-9_]. In the .NET regex language, you can turn on ECMAScript behavior and use \w as a shorthand (yielding ^\w*$ or ^\w+$). Note that in other languages, and by default in .NET, \w is somewhat broader, and will match other sorts of unicode characters as well (thanks to Jan for pointing this out). So if you're really intending to match only those characters, using the explicit (longer) form is probably best.

Page size calculation formula

Commit charge:

1. Run Performance Monitor (Perfmon)

2. Go to Data Collector Sets\User Defined

3. Right click on User Defined and select New

4. Select Create Manually and next

4. Check Performance counter

5. Add the following counters:

            Memory\Committed Bytes – Committed Bytes is the amount of committed virtual memory, in bytes.

            Memory\Committed Limit – Amount of virtual memory that can be committed without having to extend the paging file

            Memory\% Committed Bytes In Use – Ratio of Memory\Committed Bytes to the Memory\Commit Limit

Make sure you collect the information over a long period (one week at least), and the server is running at peak usage.

The page file size formula should be:

(Max value of Committed Bytes + additional 20% buffer to accommodate any workload bursts)-RAM size

For example: If the server has 24 GB RAM and the maximum of Committed Bytes is 26 GB, then the recommended page file will be: (26*1.2)-24)  = 7.2 GB

If the Hiberfil.sys file located on your local hard is growing quite large it might be time to reset the Hiberfile.sys file to default. This is also handy if you find your machine is not functioning correctly after a Hibernate then it indicates that there may be a corruption inside the Hiberfile.sys file. 

Step One::

Click on Start -> Inside the search field type on CMD -> Right click on cmd.exe and choose Run as Administrator. 

Step Two::

Enter in the following command powercfg -h off -> Press Enter

Restart the computer

Step Three::

Once the machine is turned back on open Command Prompt as admin again and enter in powercfg -h on
