Installer - order of operations Started By johnhenley When you install a new version of DNN or a module, the installer performs a number of operations, including SQL updates, upgrade code, file cleanup, etc. When you are performing a 'skip upgrade', these operations are performed sequentially by type of operation rather than performing each type within each version being upgraded. Here's an example: I assume this order of operations is used to minimize the application restarts, but it can be problematic. As an example, suppose I have vers...	1	342	1	1/29/2025 11:26 AM by johnhenley
Render module / control to HTML Started By wizard Hi, I've developed a web-form module for DNN which is working nicely (thanx to everyone for the guidance, samples etc.) My customer has now ask for a new feature - to export a page (module only, with styling etc.) to PDF.

Session.timeout value does not match with web..config value Started By Fab.Lser Hello, I see that the session.timeout value does not match with timeout value configured in web_config.

TokenReplace Started By johnhenley Trying to clean up and centralize token replacement in the forums module and use the Tokens Service in DNN. No problem getting the service and property accessors wired up for tokens. That part works great. Problem is when calling the TokenReplace method or ReplaceEnvironmentTokens method. If the source includes something that looks like a token but isn’t in the PropertySources, it gets removed. Example would be a [RESX:xxx] token. If I pass in “Building DNN Modules, Providers etc. RESX:Upd...	6	488	2	8/14/2024 4:45 PM by johnhenley

Two modules added Started By Michael Tobisch No idea why - I wrote a custom module. It compiles without errors, it does not show any error or warning in the EVS, it installs without any error. But everytime I try to add it on a page, there are two instances of the module (different IDs!) added to the page. I can't find the reason. Any ideas Happy DNNing!

Preserving query string parameters during portal navigation Started By Seek78 Hello, I am porting several modules developed in DNN 7 to DNN 9.11. Former colleagues modified the (sealed) 'DotNetNuke.Common.Globals.NavigateURL' class to introduce a collection of parameters to be added and stored in query string. Is there a smart way to do the same thing with DNN 9, possibly without modifying the DNN code base Thanks Seek	10	1431	0	7/26/2024 11:31 AM by Seek78
