"vba while loop" Code Answer's

excel vba while...

By Excel Hero on Mar 31, 2020

'In VBA, there is no 'While... End While' loop.

'Attempting to use the above construct will result in a compile-time
'error.

'But VBA does have two loops that use the keyword, 'While'...

While c < 100
	c = c + 1
	'But VBA does not have an 'Exit While' statement.
Wend

Do While c < 100
	c = c + 1
	If c = 75 Then Exit Do
Loop


'The 'Do Loop' can also be written as:      
Do 
	c = c + 1
	If c = 75 Then Exit Do
Loop While c < 100
            
'--------------------------------------------------------------------
            
'The loops can also run backward...
            
c = 99
While c
    'Do something with c here
	c = c - 1
Wend           

c = 99
Do 
    'Do something with c here
	c = c - 1
Loop While c

vba while loop

By Excel Hero on Oct 18, 2020

i = 0
While i < 100
    'Code here is executed 100 times.
    i = i + 1 
Wend

'Notes: The While loop is terminated with the 'Wend' keyword.
'
'       The While loop must include a Boolean expression directly after
'       the 'While' keyword and the loop will execute for as long as the 
'       Boolean expression evaluates to True. This expression should be
'       based on something that has the POTENTIAL TO CHANGE on each cycle
'       through the loop. For example, 'i' in the above code.
'  
'	    The While expression is evaluated at the beginning EACH cycle through 
'       the loop. The expression DOES NOT NEED to be NUMERIC; but it must 
'       evaluate to True or False. The While loop will be skipped entirely if 
'       the expression evaluates to False before the loop begins.
  
'       The following code demonstrates how the above While loop
'       functions (without actually using the 'While' and 'When' keywords):

i = 0
LoopStart:
    If (i < 100) = False Then GoTo LoopEnd
        'Code here is executed 100 times.
        i = i + 1
    GoTo LoopStart
LoopEnd:  

'      This is for demonstration purposes only. Although these two loops are
'      equivalent, using the 'GoTo' statement should be avoided. The While loop
'      accomplishes the exact same task, but cleanly, without the 
'      line labels and without the 'GoTo' statements.
'
'Note: VBA does not include an 'Exit While' statement to terminate the loop
'      early. VBA does include the 'Exit Do' statement for the Do loop and 
'      also the 'Exit For' statement for the For loop. But it is possible
'      to exit the While loop early with a 'GoTo' statement, but again, the 
'      'GoTo' statement should be avoided. It's also possible to exit
'      the While loop with the 'Exit Sub' and 'Exit Function' statements.
'      But of course, these last two statements will not only exit the
'      While loop, they will also immediately exit the current procedure.
'    
'Note: From an efficiency standpoint, the For loop may be a better choice
'      than the While loop because the For loop's range is calculated only
'      once, before the For loop starts. By contrast, the While loop's
'      expression is evaluated before each and every cycle of the loop.

  iTotalPrints = 5

  For iCount = 1 To iTotalPrints
      MsgBox Prompt:=iCount, Title:="Method: Fundamental"
  Next

'SYNTAX
'	For <your-variable-to-be-used> = <first-number> To <last-number>
'		'Code that uses <your-variable-to-be-used>
'	Next

' ================================================================
' METHOD: WITHIN AN ARRAY

 'EXAMPLE
  Dim sTextList(4) As String 'Note: doesn't have to be of "String" data-type
  sTextList(0) = "aaa"
  sTextList(1) = "bbb"
  sTextList(2) = "ccc"
  sTextList(3) = "ddd"
  sTextList(4) = "eee"

  For Each sSeparateText In sTextList
