Commenting Code

 Putting `comments` in your code isn't just for code that you're going to share with other developers; it's a way for you to be able to understand what you wrote yesterday next week.

There is no use coming up with a kick-ass algorithm if you don't remember how to use it. Make yourself a friendly note explaining why and how. It is a kindness to your future self.

Don't be so clever that you write code that is useless to you later.

The SQL Distinct Key Word

This solution is for returning one record per user with either a min or max value in one of the record's fields.

stackoverflow has discussions/solutions for this topic listed under:   

---------------------------------------------------------------
SELECT DISTINCT ON (P.ID) PR.PRACTICENAME AS "Practice", P.FIRSTNAME AS "First Name", P.MIDDLENAME AS "Middle Name", P.LASTNAME AS "Last Name", A.DATE::date AS "Last Appointment Date"

FROM PEOPLE AS P
JOIN CLIENT C ON C.ID = P.CLIENT_ID
JOIN PRACTICE PR ON PR.ID = P.PRACTICE_ID
JOIN APPOINTMENT A ON A.CLIENT_ID = C.ID

WHERE A.DATE IS NOT NULL

ORDER BY P.ID, A.DATE DESC
--------------------------------------------------------------- 

The beauty of this query is that is returns only the record for each client's latest appointment without  the use of complex sub-queries. Granted, the results may have to be further sorted, either using SQL or another tool, but it does return only one row per CLIENT and that row is for their LATEST appointment date.

Excel Parsing Formulae

Parse rightmost word in a cell:
=RIGHT(A1, LEN(A1)-FIND("*",SUBSTITUTE(A1," ", "*",LEN(A1)-LEN(SUBSTITUTE(A1," ",""))))

Parse location:
=MID(A2,FIND("Location: ",A2,1)+14,FIND("(",A2,FIND("Location: ",A2,1))-FIND("Location: ",A2,1)-14)
=MID(A2,FIND("Location: ",A2,1)+14,FIND("(",A2,FIND("Location: ",A2,1))-FIND("Location: ",A2,1)-14)
[ Number of characters: FIND("(",A2,FIND("Location: ",A2,1))-FIND("Location: ",A2,1)-15 ]

ParseName(fwd):
=PROPER(MID(A2,SEARCH("Name: ",A2,1)+6,SEARCH("Email:",A2,1)-(SEARCH("Name:",A2,1)+9)))
=PROPER(MID(A2,SEARCH("Name: ",A2,1)+6,SEARCH("Phone:",A2,1)-(SEARCH("Name:",A2,1)+8)))

ParseEmail:
=TRIM(LOWER(MID(A2,FIND("mailto:",A2,1)+7,(FIND("Home Location: ",A2,1))-(FIND("mailto:",A2,1)+9))))
=TRIM(LOWER(MID(A2,FIND("Email: ",A2,1)+8,(FIND("Phone: ",A2,1))-(FIND("Email: ",A2,1)+12))))

Concatenate middle and last names (& appellations):
=PROPER(TRIM(CONCATENATE(IF(LEN(C2)=1,C2&".",C2),IF(ISBLANK(D2),""," "&D2),IF(ISBLANK(E2),""," "&E2),)))
=PROPER(TRIM(CONCATENATE(IF(LEN(C2)=1,C2&".",C2),IF(ISBLANK(D2),""," "&D2),IF(ISBLANK(E2),""," "&E2),IF(ISBLANK(F2),""," "&F2))))

Parse location (in Body):
=MID(A2,FIND("Location: ",A2,1)+13,FIND("(",A2,FIND("Location: ",A2,1))-FIND("Location: ",A2,1)-14)

Parse location (in Subject):
=IF(SEARCH(" in ",A2,1),RIGHT(A2,LEN(A2)-SEARCH(" in ",A2,1)-3),)
=IF(SEARCH(" in ",C2,1),RIGHT(C2,LEN(C2)-SEARCH(" in ",C2,1)-3),)
=IF(SEARCH(" in ",D2,1),RIGHT(D2,LEN(D2)-SEARCH(" in ",D2,1)-3),)
=IF(SEARCH(" in ",C2,1),RIGHT(C2,LEN(C2)-SEARCH(" in ",C2,1)-3),IF(SEARCH(" for ",C2,1),RIGHT(C2,LEN(C2)-SEARCH(" for ",C2,1)-4),))
=IF(SEARCH(" in ",D2,1),RIGHT(D2,LEN(D2)-SEARCH(" in ",D2,1)-3),IF(SEARCH(" for ",D2,1),RIGHT(D2,LEN(D2)-SEARCH(" for ",D2,1)-4),))

Buttons from images

You totally CAN make an image into a button that loads a new page without JavaScript.


The usual reason for wanting to make an image into a button without using the usual link tags, i.e.,


Here's an alternative to having to define a JavaScript function for the onclick event:

    


- or -


    
onClick="location.href='index.html'">





Apply attributes using CSS:


#clickhere {
    background-image: url('pathtoimage/image.png');
    height: 20px;
    width: 75px;
}

HTML and JavaScript for parsing E-mails and URLs

HTML part:
<textarea name="Block2" rows="20" cols="50"></textarea><br />
Enter a regular expression type:
<select name="re" onchange="parseWith()">
  <option value="^\W" selected="selected">Choose an expression</option>
  <option value="[\w\.\-]+@[\w\.\-]+\b">E-mails</option>
  <option value="\w{3,6}:/+[\w.]*">URLs</option>
</select><br />
<form name="outform"><textarea name='result' rows='20' cols='50'></textarea></form>
 
JavaScript part:
function parseWith(){
 var txtI = document.text2.Block2.value;
 var re = document.text2.re.value;
 var use = new RegExp(re,"g"); // RegExp constructor compiles entered value to a JavaScript valid regex
 var txtO = txtI.match(use);
  document.outform.result.value = txtO;
 replaceCommas();
}

function replaceCommas(){
 var txt = document.outform.result.value;
 var re = /,/g;
 var rTxt = txt.replace(re,"\n");
  document.outform.result.value = rTxt;
 var para = document.getElementById("label");
 para.lastChild.nodeValue = "";
 para.lastChild.nodeValue = "paragraph separated values";
}
