Requirements

Excel version

This model uses Excel's RTD mechanism, which is only available in Excel XP upwards. It cannot be used with Excel 97 or Excel 2000.

Operating system

The model requires Windows 2000 or above, since Windows 98 does not support multi-threading.

Deliverables

The deliverables required for the projects discussed here include the following files and folders:

File	Description
Samples/AvgOptAsync	Source code for the asynchronous Excel add-in discussed below.
Samples/XllRtdLink	Source code for the RTD server discussed below.
Samples/Bin/XllRtdLink.dll	Compiled RTD server module.

Installation

The model uses a COM module (XllRtdLink.dll) to support Excel's RTD mechanism. You should register the RTD server module XllRtdLink.dll, in one of the following ways:

1. Use REGSVR32 at the command line, e.g.

   REGSVR32 "C:\Program Files\Planatech\XllPlus\Samples\bin\XllRtdLink.dll"

2. Build the project Samples\XllRtdLink\XllRtdLink.sln. Choose either the Debug or the Release MinDependency build.

Note: The XllRtdLink DLL is automatically registered when you install the XLL+ toolkit on a development machine. You only need to register it yourself when you deploy XLLs with asynchronous functions to another machine.
