I made an ActiveX DLL and I registered. I want to call the functions into it in the same way that I call the API functions, for example functions into a USER32.DLL. But if I declare and call the function that is into my DLL I receive this error message:
Can't find DLL entry point Test in Proyect1
'Test' is the function tha I made into 'Proyect1.DLL'
The code of my ActiveX DLL is:
Code:
Public Function Test(x As Integer, y As Single) As Integer
MsgBox x & " - " & y
Test = 7365
End Function
And the code of the EXE proyect from I want to call the Test function is:
Code:
Option Explicit
Private Declare Function Test Lib "proyect1" (ByRef x As Integer, ByRef y As Single) As Integer
Private Sub Form_Load()
Dim s As Integer
s = Test(3, 13.5)
MsgBox "The returned value is: " & s
End Sub
Any idea will be deeply appreciated!
Thanks

You are making COM dlls, not traditional C++ dlls.
To use, you need to add a reference to your ActiveX dll via the PROJECT --> REFERENCES and instantiate the object in code:
Code:
'declare variables, etc.
Dim objMyClass as MyDLL.MyClass
dim varReturnValue as variant
'instantiate instance of class
set objMyClass = new MyDLL.MyClass
'invoke function in class
varReturnValue = objMyClass.DoSomething(<Param1>, <param2> )
'all done for now, destroy object
set objMyClass = Nothing

Yes Tom but, Is there any way to make a DLL and call its functions in the same way as an API function using VB?

A clue I have not!
Speculation:
'Cant find DLL entry point' means that the library is not loaded into memory. Maybe you can call another API to load the library into memory, then call one of its functions.
Anyone else?
