Hi
I'm writing a module that I want to work on all DNN 4 and 5 versions.
I'm stumbling on how best to write my code.  As an example I'm finding out if the current page is set to use SSL.  In DNN 5 and later versions of 4 there is a property IsSecure on the TabInfo class.   But in early versions of 4 the idea of making pages secure doesn't exist.
How should I write some code without having to provide a different version of an install file for different DNN versions?

Great. Thanks for that.

I like the look of the Reflection code in the iFinity blog. I have used that and got it working. What is your concern about it not working in partial trust environments?

I've used the below code to determine if the IsSecure property is available and then to call it (with Reflection) if so.
I changed the trust setting in my web config on my localhost to Medium and the code still runs fine so does that mean it wont be an issue for me?

if (HasProperty(page, "IsSecure"))
{
Type tabInfoType = Type.GetType("DotNetNuke.Entities.Tabs.TabInfo, DotNetNuke");
if (tabInfoType != null)
{
//run the DNN 5.0 specific jQuery registration code
//tabInfoType.InvokeMember("IsSecure", System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Static, null, tabInfoType, null);
PropertyInfo IsSecureProp = tabInfoType.GetProperty("IsSecure", typeof(bool));
SSLMessage.Visible = (bool)IsSecureProp.GetValue(page, null);
}
}
