I am more than just a survey tool : Menu system

by

So we have designed our login system, what’s next ? Well once we have logged in we need to have the ability to choose some menu options. In this article I will show you how we can take a single response question and convert it into a menu. We will also setup on one of the menu options a sub menu so that you will be able to make your menu system as deep as you require.

I am more that just a survey : The Login System ( 3 / 3 )

by

In this final article about the login system we will see how we can validate the user login credentials via a system we have created. We will create a user survey and get our menu system to validate against that. I will show you how you can use ODBC to connect the two surveys together and ensure that only the correct users are allowed to login

I am more that just a survey : The Login System ( 2 / 3 )

In the last article we saw how to create the questions that would hold our login info and the script to handle the actual logon process. In this article we will explore using the DPM object to authenticate our users to decide if they can login or not and take a look at the IsInRole feature.

Learn VBA : Sort an Array

by

I quite often, to get ideas for articles look at the things people search for on the site. And recently I did just that and noted that someone looked up how to do a VBA array sort. If that was you , then this quick article is for you.

First off lets define the array and populate it.

Dim oArray[10]
     
    oArray[0] = "J"
    oArray[1] = "I"
    oArray[2] = "H"
    oArray[3] = "D"
    oArray[4] = "F"
    oArray[5] = "G"
    oArray[6] = "E"
    oArray[7] = "B"
    oArray[8] = "C"
    oArray[9] = "A"

In this example we are going to do a bubble sort, but there are lots of different types. Bubble is by far the easiest at the cost of speed, it is by no means the fastest sort.

    
   
Dim iFirst,iLast,iCount,iNestCount
Dim sTemp,sList
     
    iFirst = LBound(oArray) 
    iLast = UBound(oArray) 
    For iCount = iFirst To iLast - 1 
        For iNestCount = iCount + 1 To iLast 
            If oArray[iCount] > oArray[iNestCount] Then 
                sTemp = oArray[iNestCount] 
                oArray[iNestCount] = oArray[iCount]
                oArray[iCount] = sTemp 
            End If 
        Next
    Next

So what does our code do, well we first of we find the first record in our array and then we find the last , and then we begin to loop our array. Next we start to loop the array again , starting with the element we are on and checking to see if any of the following elements are greater than the one we currently have selected in the first loop , if it is greater then we swap them around and then continue on , so to help you visualise this, this is what happens

iCount = 0,  Array[iCount] = J / iNestCount = 1,  Array[iNestCount] = I
SWAP,  Array[iCount] = I / Array[iNestCount] = J
iCount = 0,  Array[iCount] = I / iNestCount = 2,  Array[iNestCount] = H
SWAP,  Array[iCount] = H / Array[iNestCount] = I
iCount = 0,  Array[iCount] = H / iNestCount = 3,  Array[iNestCount] = D
SWAP,  Array[iCount] = D / Array[iNestCount] = H
iCount = 0,  Array[iCount] = D / iNestCount = 4,  Array[iNestCount] = F
iCount = 0,  Array[iCount] = D / iNestCount = 5,  Array[iNestCount] = G
iCount = 0,  Array[iCount] = D / iNestCount = 6,  Array[iNestCount] = E
iCount = 0,  Array[iCount] = D / iNestCount = 7,  Array[iNestCount] = B
SWAP,  Array[iCount] = B / Array[iNestCount] = D
iCount = 0,  Array[iCount] = B / iNestCount = 8,  Array[iNestCount] = C
iCount = 0,  Array[iCount] = B / iNestCount = 9,  Array[iNestCount] = A

and this keeps on going until we have looped round all the items in the array. Are final bit of code just lets us display the results.

     
    For iCount = 1 To UBound(oArray) 
        sList = sList + oArray[iCount] 
    Next 
    
    Debug.MsgBox(sList)

So there you have it some code to sort an array. I hope you find it useful. Please don’t forget if you cannot find what you want , leave a comment on the “ASK US post” and I will respond to you with an answer if I can.

In this next set of articles I am going to show you how we can take Data Collection Scripts and get them to make some cool things. To me a survey can be so much more than just a survey, it can, with the use of some simple concepts, be a dashboard , online comments cleaner, panel or report delivery system. So what skills do we have to have to make let’s say a very simple dashboard system. Well if you know how to write a data collection survey , you know how to edit JavaScript , you have read my posts on ODBC connections and have learnt HTML you have all the tools you need.
