I am just getting into a little php and programming and I would like to know what something like
If ($sMap != "") what does !="" mean and what does "" and " " on its own generally mean?

Thank you.
Before doing a linear regression on a data-set one needs to find out a few things about the data:

  • is there is a linear relation between the dependent and independent variables
  • are the variables normally distributed (if not, do a Data Transformation)


  1. Book1.xlsx
  2. In Excel, do I simply use the CORREL() function to determine a linear relation between the dependent and independent variables?
  3. How do I interpret these results (i.e. low value = low correlation, high value = high correlation)?
  4. To test normality, can I simply use the QQ Plot test or should I use other tests, like the K-S Test as well?
  5. How do I interpret the K-S Test results?
  6. How do I go about doing a "Data Transformation" and how do I know whether I should do it?
  7. Please do not confuse things with only Statistics talk when giving an answer because I might not understand what you're saying. I've uploaded a sample of a data-set.

Thank you!
i got this code from internet, i want to run a test on this.  where i can get a good software where i can run tests like this that can support more than just one language. i mean if it can have plug-ins for other languages?

what i need something that i can run as portable, i do not want MS visual studio .

I have a table


 PK                                      FK                            
 OrderDetailID                OrderID           LineNo          
 8238                                7780                  1
 8239                                7780                  2
 8240                                7781                  1

 How do I create the column LineNo based of OrderID to increment starting with one?  So once the FK OrderID changes it starts back to 1 for the next orderid.  The lineno field must autogenerate and needs to be stored.

What type of codes are the following and how do you enter them using a standard PC keyboard?

asc 225

I thought the technique was to hold down the ALT key while entering the characters in the number pad. However, for the first one, I've tried each of the following entries and only get clubs (♣♣♣).


I found them in an AutoHotkey script in which case they code for ß & Δ respectively.

b::Send {ASC 225}
+c::Send {U+03B4}

Good Afternoon.

our IT team has changed the Office programs from 32bit of Excel to 64bit, now our finance department has a lot of files with macros in them, like around 598 of those files have codes that use the window API by using the Declare statement.
i would need to convert a bunch of 32bit API calls in these files to 64bit compliant calls while preserving 32bit compatibility as well.

i created the attached template. where i can put the directory, then file names and then two box for searching code and replacing it with code.

so, ideally , the code to loop through all files in the referred directory and its subfolders and if the files listed in Column C found then initiate search on those files by finding the codes listed in column D and replace them with code in column E.

i search the whole day and i could not find anything or any help on google or in any other forum, which brings me here to EE VBA gurus and i am hoping someone would be able to help me here.

thank you in advance.

I trying to right a script that will import appointments in into Outlook 2016 from excel 2016. I have add some lines to the follow, but still no Joy.

What I would like to do is use the headings ,  to import, update the group calendar.

Subject      Categories            Location                        Start Date      Start Time      End Date      End Time      Description      Required Attendees      Show Time As      Reminder Set      Remind Beforehand      

Sub RegisterAppointmentList()
    ‘ adds a list of appontments to the Calendar in Outlook
    Dim olApp As Outlook.Application
    Dim olAppItem As Outlook.AppointmentItem
    Dim r As Long
    On Error Resume Next

    Set olApp = GetObject("", "Outlook.Application")
    On Error GoTo 0
    If olApp Is Nothing Then
        On Error Resume Next
        Set olApp = CreateObject("Outlook.Application")
        On Error GoTo 0
        If olApp Is Nothing Then
            MsgBox "Outlook is not available!"
            Exit Sub
        End If
    End If
    r = 6 ‘ first row with appointment data in the active worksheet
    Dim mysub, myStart, myEnd
    While Len(Cells(r, 2).Text) <> 0
        mysub = Cells(r, 2) & ", " & Cells(r, 3)
        myStart = DateValue(Cells(r, 5).Value) + Cells(r, 6).Value
        myEnd = DateValue(Cells(r, 5).Value) + Cells(r, 7).Value
        ‘DeleteTestAppointments mysub, myStart, myEnd
        Set olAppItem = …

I want to NOT pass objects or references in the constructor.  I think the instantiated object should know who instantiated it, and it should be able to scope the instantiator's  objects.  
Object A instantiates Object B.  Can Object B access Object A's  properties, members, etc?

Below is actual sample showing real example.  Advice please?

Kind Regards

Although I have many skills outlined on my resume, I want to add another practical skill, in case my current skills become obsolete.

So, I have been toying with the idea of teaching myself Swift or some other iOS programming language in order to be able to create apps for the iPhone.

Out of the many new business skills a professional could learn, would this be the best?  

If so, how long does it take to learn and is it extraordinarily difficult?  Are there are good and free tutorials online that will successfully teach the lay person such a programming language?


Hi there,

It's been a while since I've seen this type of equation, not sure what to do here:
I am not sure this even makes sense, because if i = 1 then why not just say X subscript 1, instead of X subscript i? Also, "n-1" implies that we're considering a sample set of "n" numbers, which implies that the value of "i" changes "n" amount of times.

I don't know for sure though.

Hope you will help.

I had this question after viewing Index Match Vlook up for a master file.

I have added some code to inform the user if the part does not exist on the master
For Each cell In rng
    If Application.CountIf(sws.Rows(4), cell.Value) > 0 Then
        col = Application.Match(cell.Value, sws.Rows(4), 0)
        r = Application.Match(cell.Offset(0, 2).Value, sws.Columns(col), 0)
        If col > 0 Then
            If Err.number = 13 Then
                cell.Offset(0, 3).Value = "Part not in master"
                 cell.Offset(0, 3).Value = sws.Cells(r, myCodeCol)
            End If

i have been thinking about the first column and the issue getting all the invoices eventually to one sheet. The problem is that none of them put a column showing it is from them. I don't want the user to type in the company name becuase that would just open the door to problems So how about this.  when the user open the invoice spreadsheet, they will run a vba script , and it will ask who the company is:
ZED .. Maple.  etc.  the available companies  would be based upon ROW 4 in the master sheet in (sheet2). They choose the company and it is copied down in col A to the end of the data . I have run a few manual samples and it works good.  So my question is , how do i get that list to show up in VBA ?
