Hi,
First of all I recommend to download Ndde C# library not to stick to
mad WinAPI DDE calls.
http://workspaces.gotdotnet.com/ndde
OK, now you can develop a test WinForms application easily using Ndde
example, to check your RSL DDE-server.
Hope it works.
You're reusing the same solution in ASP.NET app. It works? No, of
course. It's time for some magic actions...
1. Open Services, find IIS Admin, open its Properties, go on Log on
tabpage and check "Allow service to interact with desktop" ON.
2. Open Users Accounts, include ASPNET user in Administrators group.
3. Restart the PC.
Also don't forget to run Windows Firewall and check if IIS TCP port
(80) is not blocked (add it with Add Port... button on Exceptions
tabpage if it's needed).
Try your ASP.NET again. Hope it works now.
.
