not really, i'm just trying to estalibsh a connection to db and call a function from a reference. function name is "GetControlInformation", its in a .DLL, the purpose of this function is to return me whether connection is successful or not, that's all it does
So is mmControl the class used to work with the DLL?
Where is GetControlInformation()?

function GetControlInformation(pControlPath : PChar;
var pIsAccessDB : Boolean;
pControlServer : PChar;
pSQLName : PChar;
pSQLPassword : PChar;
pError : PChar): Boolean;yes mmControl is the control working with the DLL
"PCHAR" is a buffer here
If you are going to use static arrays then you can just go ahead and set the array bounds.
Dim pControlPath (0 To MAX_PATH) as String
Dim pIsAccessDB as Boolean
Dim pControlServer (0 TO 256) as String
Dim pSQLName (0 To 31) as String
Dim pSQLPassword (0 To 31) as String
Dim pError (0 To 2049) as String
If you want Dynamic Arrays, then just leave out what is between the parenthesis and use ReDim Preserve as needed.
Dim pControlPath () as String
Dim pIsAccessDB as Boolean
Dim pControlServer () as String
Dim pSQLName () as String
Dim pSQLPassword () as String
Dim pError () as String
Also, you stated VBA in your question, but have VB.Net as a selected zone. I have requested that Visual Basic be added as well since you might get better support there.
