Delphi.</font></b></p>

<p><font face="Arial">Create a new Project.</font></p>
<p><font face="Arial">Import the Type Library of the component you want to use
by selecting "Project - Import Type Library". From the list, select
"IBHNet Type Library (Version 1.0)", then click "OK".</font></p>
<p><font face="Arial">Delphi will add the file "IBHNETLib_TLB.pas"
file to your project, which contains all the functions and methods, that are
exported by the IBHNet component.</font></p>
<p><font face="Arial">Add the imported file to the "uses" section of
your project (in the sample: The "uses" section of the form).</font></p>
<p><font face="Courier New" size="2">uses<br>
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, IBHNETLib_TLB;<br>
</font></p>
<p><font face="Arial">Also add the units required to use ActiveX and COM to the
project.</font></p>
<p><font face="Courier New" size="2">uses<br>
Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, IBHNETLib_TLB,<br>
StdCtrls, ActiveX;<br>
</font></p>
<p><font face="Arial">Add the interface of the object you want to use as a
variable with the scope required. In the sample we have added the variable
global to the form in the "var" section of the form.</font></p>
<p><font face="Courier New" size="2">var<br>
Form1: TForm1;<br>
IBHNet_Obj: IIIBHnet;<br>
Value: OleVariant;<br>
</font></p>
<p><font face="Arial">Initialize the component you want to use, using the
functions generated during Import in the IBHNETLib_TLB.pas file, as shown in the
sample in the FormCreate event handler.</font></p>
<p><font face="Arial">Examine the event handlers to see how reading and writing
values from/to the PLC is managed.</font></p>
<p><font face="Arial">One of the important things when using Delphi is, that that
you make yourself familiar with safearrays and other automation compliant data
types like the Variant data type. This is especially important, if you want to
use the block-read (ReadVals) and block-write (WriteVals) functions of the
IBHNet component.</font></p>
