1. Identities

Library name: Script Utilities library
Library code: ScriptUtilities
Library CLSID: 41ABB943-5D82-11D3-9DD5-204C4F4F5020
ProgID: ScriptUtils.ZLib
Library file name: ScptUtl.DLL

2. Scripting engines without types (VB Script, JavaScript, JScript, WSH, ASP)

You can create the object using CreateObject function:

Dim ZLib
Set ZLib = CreateObject("ScriptUtils.ZLib")
ZLib.SomeMethod SomeParameters
ZLib.SomeProperty = SomeValue

You can also use CreateObject method method of Server object (ASP) to put the ZLib object to page scope or CreateObject method of WScript object in WSH.

You can also put the object to Application or Session scope using <object ...> tag in global.asa

<object runat="server" scope="application" id="ZLib"
 progid="ScriptUtils.ZLib">
</object>

Please use ActivexObject object in JScript/JavaScript to create ZLib object:

var ZLib;
ZLib = new ActiveXObject("ScriptUtils.ZLib");
ZLib.SomeMethod(SomeParameters)
ZLib.SomeProperty = SomeValue
...

3. VBA (VBA 5, VBA 6, Visual Studio, Word, Excel, MS Access, ...)

VBA 5/6: You can reference the library using menu Project -> References -> select 'Script Utilities library' in the listbox (or Project -> References -> Browse -> select ScptUtl.DLL file).
MSAccess, Word, Excel: Tools -> Macro -> Visual Basic Editor, then Tools -> References
Then you can write:

Dim ZLib As New ScriptUtilities.ZLib
ZLib.SomeMethod SomeParameters
ZLib.SomeProperty = SomeValue
    ...

Dim ZLib As ScriptUtilities.ZLib
...
Set ZLib = New ScriptUtilities.ZLib
ZLib.SomeMethod SomeParameters
ZLib.SomeProperty = SomeValue
...

You can use CreateObject function also, of course:

Dim ZLib As ScriptUtilities.ZLib
...
Set ZLib = CreateObject("ScriptUtils.ZLib")
ZLib.SomeMethod SomeParameters
ZLib.SomeProperty = SomeValue
...

4. Visual Studio .NET (ASP.Net, VB.Net, C#, J#)

You can reference the library using menu Project -> Add reference -> COM tab -> select 'Script Utilities library' in the listbox -> click Select. Then you can write (C#, J#):

 //create  a new ZLib object
 ScriptUtilities.ZLib ZLib = new ScriptUtilities.ZLibClass(); 
 ZLib.set_String("Some text value"); 
 





 String SQL; 
 SQL = "Insert Into Table (BinaryColumn) values (0x" + ZLib.get_HexString() + ")"; ...

or (VBA)

Dim ZLib As New ScriptUtilities.ZLib 
ZLib.SomeMethod(SomeParameters)
ZLib.SomeProperty = SomeValue

5. T-SQL, MS SQL stored procedures and functions

DECLARE @ZLib INT, @OLEResult INT 
EXECUTE @OLEResult = sp_OACreate 'ScriptUtils.ZLib', @ZLib OUT
IF @OLEResult <> 0 PRINT 'Error create component ZLib'

--Set a property of ZLib.
EXECUTE @OLEResult = sp_OASetProperty @ZLib, 'PropertyName', @SomeSQLValue
IF @OLEResult <> 0 PRINT 'PropertyName set problem'

--Get a value of a property of ZLib.
EXECUTE @OLEResult = sp_OAGetProperty @ZLib, 'PropertyName', @SomeSQLValue OUTPUT
IF @OLEResult <> 0 PRINT 'PropertyName get problem'

--Call some method of ZLib.
EXEC @OLEResult = sp_OAMethod @ZLib, 'MethodName', 
 @ReturnValue OUTPUT, @parameter1, @parameter2

5. Other programming environments

Please see documentation of your programing environment, work with COM objects (OLE objects, ActiveX objects). ZLib is a standard COM object, it can work with other environments, such are Delphi or PowerBuilder.
