C# - Generate And Handle User Messages Inside Methods?
Aug 5, 2011What is the best way to handle a function that might occasional fail to evaluate, but even when it does fail does not require a halt of the parent routine, though sometimes might require an explanation to the user?I have such a function, deep in my code, that returns a number. Codingwise, the simplest approach would be to make the function nullable, and return null when it can't evaluate. That way the calling routine can continue while also knowing the function failed to return a number.
However, depending upon the circumstances, sometimes I want to display the reason for the fail to the user so they know what to fix. Obviously just returning null isn't enough information. Should I be raising messages inside the function itself as it evaluates for anonymous listeners to catch, to be displayed if desired?(For those rightfully pointing out that logic functions shouldn't be responsible for creating user messages, I didn't mean to imply the function generates the full text message, just somehow transmits the reason for the problem so that the UI could later parse that into a message)
The other option I suppose would be throw exceptions inside the function if it can't evaluate, then catch and interpret to user messages if desired. However, as stated the inability to evaluate typically does not signify a halt to the routine, and now I'd have to put a Try...Catch block around the function call everytime I use it.

Donwloading From A Controller Using FTP
Jul 9, 2010I have a blackbox (with a crude ftp server on it) which has an IP address, a file on it, a username and a password. I have a PC logged on to the local network and I want to write a VB.net program that sits on the PC and when the file is created it downloads that file. from the laptop I can type ftp:192.168.43.34 in to windows explorer and see the file without having to type in a username or password (username is set to Anonymous)I require a simple program that just points to the file (ftp:192.168.23.12/banjo.txt) and grabs it to a local path (C:\banjo.txt)I have looked everywhere and not found anything that works and not interested in paying $500 for a library.

View 1 RepliesUsing A Ribbon Control As Tab Controller
Oct 12, 2010I have an application that has multiple UI layouts, sometimes on tabs, sometimes the occasional separate form.I recently bought a pack of UI elements, and I'd like to use a ribbon control as the main navigation. For the most part I want the tabs on the ribbon to function like your everyday tabcontrol. The problem is that the ribbon tabs don't each have their own page for you to lay out your controls like the normal tabcontrol does.So right now I have the ribbon control at the top of an MDI form, and instead of using multiple tab pages I have many borderless forms, and when I click on a tab of the ribbon, I maximize the appropriate form and bring it to the front. This creates the illusion of tab pages by eliminating the control boxes of the child forms.

C# - MVC: Returning Multiple Rows Of Data To Controller?
Apr 23, 2012I have a table with several rows of data that I need to return to the controller. In my view, I initially load the table by selection of a time period and clicking a button.

So everything works until I try and save. The model that is sent to the controller is completely null. The list property I have tied to the table cells returns to the controller null.
