PowerBuilder - Error calling an external function

[Former Member]

Hi,

I am trying to call a function located in a DLL that was developed for us. When I try to run the script it is showing me the following error: "Error opening DLL library Encryption.dll for external function at line ....... ".

How I am defining the External functions on PowerBuilder?

Function string EncryptStringAES &
(string plainText, &
string sharedSecret &
) Library "Encryption.dll" Alias For "EncryptStringAES"

Function string DecryptStringAES &
(string cipherText, &
string sharedSecret &
) Library "Encryption.dll" Alias For "DecryptStringAES"

How they are in the DLL ?

The class name is Crypto, and it is in the Encryption namespace.

public static string EncryptStringAES(string plainText, string sharedSecret)

public static string DecryptStringAES(string cipherText, string sharedSecret)

I am using PB 10.2.1 , for now!

Thanks.

Another way to show my issue:

--------------------------------------------

The dll was built on the .NET 2.0 and 4.0 Framework trying to identify the issue.

---

using System;

using System.Collections.Generic;

using System.Text;

namespace Test

{

publicclassClass1

{

publicstring HelloWorld()

{

return"Hello";

}

publicstring HelloWorld2(string test)

{

return test;

}

publicvoid HelloWorld3(string test1, outstring test2 )

{

test2 = test1;

}

}

}

-----------------------------------------

Local external Function definition:

Function string HelloWorld2 &
(string test &
) Library "Test.dll" Alias For "HelloWorld2;ansi"

-----------------------------------------

Calling the external function:

String ls_value, ls_returned

ls_value = Trim(sle_source.text)

ls_returned = HelloWorld2(ls_value)

IF Not IsNull(ls_returned) THEN
sle_encrypted.text = ls_returned
END IF
