I have a PictureBox control opened.

Then, here's what I need to do (Instructions in Human Language) :

1. Click on 6 different locations on the PictureBox using my mouse
button

2. Return the X,Y coordinates of each of the 6 locations and store them
in 2 one-dimension arrays namely,    Dim x(1 to 6), y(1 to 6) as Integer
 

Really glad if you could help.

This should be very easy. Here's what you do (i'm assuming you want pixel locations, not twips):
Create a form (frmMain) with two command buttons (cmdStart, cmdShow), a listbox (lstPoints), and a picturebox (picPoints) with scalemode set to pixels (3).
Here's the basic code:
(this is general declarations)
Dim ptsX(1 To 6) As Integer
Dim ptsY(1 To 6) As Integer
Dim clicking As Boolean
Dim clicks As Integer

Private Sub cmdShow_Click()
lstPoints.Clear
For i = 1 To 6
    lstPoints.AddItem CStr(ptsX(i)) + "," + CStr(ptsY(i))
Next i
End Sub

Private Sub cmdStart_Click()
clicking = True

End Sub

Private Sub Form_Load()
clicks = 0
End Sub

Private Sub picPoints_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If clicking Then
    Beep
    clicks = clicks + 1
    ptsX(clicks) = X
    ptsY(clicks) = Y
End If
If clicks = 6 Then
    clicks = 0
    clicking = False
    cmdShow_Click
End If
End Sub

xoooox,
Try the following. If you have questions, let me know.
Regards
Dalin

'1. declaration:

          Private Type POINTAPI
              x As Long
              y As Long
          End Type

          Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long

 

 2. In your picture's Click event, add:

          Dim p As POINTAPI
          Static clickCount as Integer
          If ClickCount = 0 then clickcount = 1
          If clickCount >6 then
              'Do what you like, reset or just exit
              ' I am reset it
              Clickcount = 1
             End if
          Call GetCursorPos( p )
          x(clickcount) = p.x
          y(clickCount)= p.y

Question for Dalin - why the whole big POINTAPI stuff - you don't need any API calls for this program. Just wondering...
