Declare DLL does not work in a different module

[Guillaume Audirac]

Hello,

Here is my piece of program :

Option Explicit
Declare Function VeeInitDll Lib "VeeGenApi.dll" () As Integer
Sub Main
Call VeeInitDll()
End Sub

It works well in this case.
Then, because I have to declare several long functions of my DLL, I separate the Declare and the Main program in 2 different modules :

Module1:
Option Explicit
Declare Function VeeInitDll Lib "VeeGenApi.dll" () As Integer

Module2:
Option Explicit
Sub Main
Call VeeInitDll()
End Sub

Then I run Main in Module2, with the error message "Undefined variable" at the "Call VeeInitDll()" line.
What does this mean ? Is there really an error or is it a bug ?

Thanks a lot for your help !

In principle, your approach should work. I have the DECLARE statement in the OO standard Library, and can call it from any Module I want (OO1.1.3)

Maybe the syntax checking is more strict with DECLARE functions ? Did you try

Oops, I have to correct myself. Just looked again into the code - I have written wrapper functions around the DECLARED functions to be able to call them from other modules. So it seems to be a bug (or a safety feature ? )

The reason for this error has already been described here:

The link you propose is not related to the same problem.
And I agree with the post before : to make it working properly, I need to wrap my Declare function with another function in the same Module. Then the new name can be called in any module. Strange, isn't it ?

New version which works :

Module1:
Option Explicit
Declare Function VeeInitDll Lib "VeeGenApi.dll" () As Integer
Function oo_VeeInitDll() As Integer
oo_VeeInitDll = VeeInitDll()
End Function

Module2:
Option Explicit
Sub Main
Call oo_VeeInitDll()
End Sub


So, is it a bug or intentional ?

I would rather say it is a bug, and it seems to be still present in openoffice 3.1 ...
