Hi,

You can use Like Operator or StrComp Function for Pattern Matching in Array Variable or any other Variable. You can compare the Values like below Given:

1) Bring the Array Values in loop and check the Value like this

IF a(I) LIKE "*a*" THEN
-----
-----
END IF
You can refer more about the Like Operator in

http://msdn.microsoft.com/en-us/libr...xw(VS.71).aspx


2) You can use StrComp Function like this

IF StrComp(a(I), "a") THEN
-----
-----
END IF

And there is no way to find "pattern" of one array in other? something like a(0) = b, a(1) = c and b(0) = a, b(1) = b, b(2) = c, b(3) = d.

bool = a like *b*

???

hi,

You can do like below when using the variable instead of values.


IF a(0) like "*" & b & "*" THEN
-----------
-----------
END IF

Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text) 
  1. Private Sub Command1_Click()
  2. Dim A(2) As String
  3. Dim B(4) As String
  4.  
  5.     A(0) = 3
  6.     A(1) = 2
  7.     A(2) = 67
  8.  
  9.     B(0) = 89
  10.     B(1) = 3
  11.     B(2) = 2
  12.     B(3) = 67
  13.     B(4) = 99
  14.  
  15.     If A(0) Like "*" & B & "*" Then
  16.         MsgBox "ahoy"
  17.     End If
  18.  
  19. End Sub

It looks like ill have to use loops, because these is not working. And i don't need one value i need to find is one entire dimension of array in other. I am afraid loops will last too long.

hi,

Array can be used only by loops and that could be very if u understand wel.
Try the below coding and if you have any doubts in below codings you can ask me i will explain u in detail.

In Below coding, i had used nested loop (i.e). Loop is nothing but Loop is to make a rotation until it gets the end value. If it is Nested Loop then 2 loops used (i.e)
For i = 0 to 10 'Outer Loop
For j = 0 to 5 'Inner Loop
---------
Next
Next

Outer Loop have the value and comes to the inner loop. Then the inner loop starts the rotation until it getting the end value after that move to the outer loop and goes on until the outer loop ends. Simply we can say one element of outer loop compare with all element in the inner loop.

If u understand the loop concept clearly then only u can do anything in any language.





[QUOTE=Teropod;650258] 
Private Sub Command1_Click()
Dim A(2) As String
Dim B(4) As String
Dim intI as Integer       'intI Variable for A()
Dim intj as Integer       'intJ Variable for B()

    A(0) = 3
    A(1) = 2
    A(2) = 67
    
    B(0) = 89
    B(1) = 3
    B(2) = 2
    B(3) = 67
    B(4) = 99
    
 'Nested Loop
     For intI = 0 to Ubound(A)
           For intJ = 0 to Ubound(B)  'Loop works until the size of the B() Array
                If A(intI) Like "*" & B(intJ) & "*" Then  'A() compared with the all element in the B() 
                      MsgBox A(intI)
                End If
          Next
     Next  

    
End Sub

Hi,

Try this one. I think this may be useful to u.

Visual Basic 4 / 5 / 6 Syntax (Toggle Plain Text) 
  1. Private Sub Command1_Click()
  2. Dim A(2) As String
  3. Dim B(4) As String
  4. Dim C as String
  5.     A(0) = 3
  6.     A(1) = 2
  7.     A(2) = 67
  8.  
  9.     B(0) = 89
  10.     B(1) = 3
  11.     B(2) = 2
  12.     B(3) = 67
  13.     B(4) = 99
  14.  
  15.     IF UBound(Filter(B, A(0), True, vbTextCompare)) >-1 THEN
  16.           C=Filter(B, A(0), True, vbTextCompare)    
  17.            MsgBox C(0)
  18.     End If
  19.  
  20. End Sub
