First the disclaimer

I decided to run up the kbmMWSpider extensions for dotnet in Highlander and check that it all worked nicely. It did and it was great to see Spider and Delphi code back together for DotNet2.
Here is a sequence of screenshots to show you what I did but basically I ran up an ASP.net application, added a page and put a grid and a button on it. In the OnClick event of the button I make a call out to a kbmMW server and bind the returned data to the grid.
Here we go
1) Startup the Highlander IDE
2) Add the kbmMWSpider20.dll assembly to the references section of the project
3) Drop a GridView and Button control onto the Default.aspx page
4) Add the appropriate units to the implementation section of the page.
5) Implement the code for the button.
6) Run the application!
When I first ran the project up I hit a problem because I'd previously changed the application server return values. However in debugging my ASP.net client the seemless debugging in Highlander was nicely highlighted. Here is a screen shot of some C# code of kbmMWSpider that I traced into seemlessly.
There we have it. kbmMWSpider working nicely in Highlander.
I'm planning another Blog showing the full client framework running but for now it's off to get some breakfast
