Stupid User Question

Hi all,

can anybody help me ?

I'd like to do some API stuff.
I got this code from VBAPI.com

1) Declare Function LineTo Lib "gdi32.dll" (ByVal hdc As Long, x As Long, ByVal y As Long) As Long

2)' Draw a red line from (0,40) to (100,50) on the window Form1.
Dim pt As POINT_TYPE ' needed for another API function
Dim retval As Long ' return value

3)Form1.ForeColor = RGB(255, 0, 0) ' set the foreground drawing color of Form1 to red
retval = MoveToEx(Form1.hdc, 0, 40, pt) ' set the current point to (0,40)
retval = LineTo(Form1.hdc, 100, 50) ' draw a line from current point to (100,50)

Questions :
Where to declare 1) ???
In General declarations ???

Where to declare 2) ???

Last question : I have to declare the POINT_TYPE structure with Type POINT_TYPE
x as long
y as long
End Type

Where to declare this ???

Any help would be very much appreciated !!!

All ion General decleration section

Thank you ver much amitabh !!

Anyway, I don't get it !?

General Declaration
Declare Function LineTo Lib "gdi32.dll" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long
Type POINT_Type
x As Long
y As Long
End Type
Dim pt As POINT_Type
Dim retval As Long

Private Sub Command1_Click()
Form1.ForeColor = RGB(255, 0, 0)
retval = MoveToEx(Form1.hdc, 0, 40, pt)
retval = LineTo(Form1.hdc, 100, 50)
End Sub

gives the following error message:
Compile error : Cannot define a public user-defined type within a private object module.

???

Can you help me again, please ?!
Thank you !!

If you wish to use the code in a form or a class module then the declarations must be private thus:

Code:

---

Private Declare Function LineTo Lib "gdi32.dll" (ByVal hdc As Long, ByVal x As Long, ByVal y As Long) As Long

Private Type POINT_Type
  x As Long
  y As Long
End Type

---

Otherwise they must be declared in a .bas standard code module.

Thanks MerrionComputin !

It works !
I was close sometimes but always forgot to declare the MoveToEx , and stupid enough NOT to understand the error message !

Thanks !
