Purpose

You can create objects and invoke methods from both managed and unmanaged dlls.

 

Usage

Rapise provides API calls to work with managed DLLs.  The Windows object WScript can be used with unmanaged DLLs.

 

Managed DLLs

·Util.InvokeMember: Invoke a class method in a managed DLL.
·Util.CreateClassInstance: Creates an instance of a class in a managed DLL.
·Util.SetFieldValue: Sets a field value in an object created with CreateClassInstance.

 

Unmanaged DLLs

·WScript.CreateObject("DynamicWrapper"): Create a DynamicWrapper object.  The Register and ShellExecute methods of the DynamicWrapper object can be used to invoke DLL methods as in the following example:

 

var UserWrap = WScript.CreateObject("DynamicWrapper");

UserWrap.Register("shell32.dll", "ShellExecute", "I=hssssl", "f=s", "r=l");

UserWrap.Register("USER32.DLL", "MessageBoxA", "I=HsSu", "f=s", "R=l");

UserWrap.MessageBoxA( null, "" + elapsed, "Time Elapsed:",  0x30 );

 

Test Samples

There is a Samples folder in your Rapise directory.  There are two test samples that illustrate working with DLLs:

·UsingDLLHandlerManaged
·UsingDLLHandlerUnManaged
