Using For Each...Next Statements

For Each...Next statements repeat a block ofstatements for eachobject in acollection or each element in anarray. Visual Basic automatically sets a variable each time the loop runs. For example, the followingprocedure closes all forms except the form containing the procedure that's running.

Sub CloseForms() 
 For Each frm In Application.Forms 
 If frm.Caption <> Screen. ActiveForm.Caption Then frm.Close 
 Next 
End Sub

The following code loops through each element in an array and sets the value of each to the value of the index variable I.

Dim TestArray(10) As Integer, I As Variant 
For Each I In TestArray 
 TestArray(I) = I 
Next I 

Looping Through a Range of Cells

Use a For Each...Next loop to loop through the cells in a range. The following procedure loops through the range A1:D10 on Sheet1 and sets any number whose absolute value is less than 0.01 to 0 (zero).

Sub RoundToZero() 
 For Each myObject in myCollection 
 If Abs(myObject.Value) < 0.01 Then myObject.Value = 0 
 Next 
End Sub

Exiting a For Each...Next Loop Before it is Finished

You can exit a For Each...Next loop using the Exit For statement. For example, when an error occurs, use the Exit For statement in the True statement block of either an If...Then...Else statement or a Select Case statement that specifically checks for the error. If the error does not occur, then the If…Then…Else statement is False and the loop continues to run as expected.

The following example tests for the first cell in the range A1:B5 that does not contain a number. If such a cell is found, a message is displayed and Exit For exits the loop.

Sub TestForNumbers() 
 For Each myObject In MyCollection 
 If IsNumeric(myObject.Value) = False Then 
 MsgBox "Object contains a non-numeric value." 
 Exit For 
 End If 
 Next c 
End Sub
