Dot Net Nuke (DNN) Host and Admin Menu Features #Root #By Sayed Ahmed

These are the options that you see on Host Menu, when you just install. Your production might have more depending on if any additional stuff are installed or not

Common Settings:
Dashboard
Extensions
File Management
Host Settings
Site Management

Advanced Settings:
Configuration Manager
Device Detection Management
HTML Editor Manager
Lists
Schedule
SQL
SuperUser Accounts
Vendors

 

So, you can configure for automatic update and check for the availability of updates

You can see what Critical, Moderate and Low security mean
As it came along the Update
The steps:
Usually you copy/replace the new files. usually the dll files will have most of the changes.
More details:
You need to take a backup of your existing site and database.
Modify your web.config file set autoupdate to false
copy all the files to your current site
the go to
www.example.com/install/install.aspx?mode=upgrade and follow the process.
another strategy might be
create a site only for update like
update.example.com based on your existing site and database (still keep some backup)
then copy all the new files to this update version
then go the install page
after install check if everything works
then you can modify IIS to make this update site to be the live/production site.
let’s show you an internet resource on this…
This is a good resource on upgrading DNN
http://www.dnnsoftware.com/wiki/upgrading-dotnetnuke
we are upgrading
anyway…
Just some URL rewrites, in PHP/Apache you do this using url-rewrite in .htaccess file
So, you can see from, Host->advanced settings you can change the following
If you did not use this feature of DNN before, probably you do not know that DNN has these features; however, you might already used similar features in other CMSes or in other software. you know some without knowing; just needed to know DNN uses those…
sometimes, the difference between theory and practice:
theory teaches you all the different possible stuff, where practical you just need to know what are the stuff from theory/general stuff are used in the particular technology: some truth, some false in the above statement..never mind…theory is evil…

Proxy Settings

SMTP Server Settings

Performance Settings

jQuery Settings

CDN Settings

Client Resource Management

Membership Management

Login IP Filters

Search Settings

Ip filtering can be a god idea, if your site is internal only…
also, you can block IPs where attacks originated from…a range or specific
apparently lucene is used as search.
Lucene is available as search engine for Drupal and other CMSes as well
including Kentico..
Using site management, you can create and configure multiple sites….
these new sites can use the same database
you can utilize users : specific to this site also users can be shared among multiple sites..
check yourself…how and is it possible really…
So you can see the extensions used
and you can configure/change settings for these…
So you can see available extensions such as login/authentication through twitter/facebook or similar
you can also search and install third party extensions….
Dashboard -> showing some info
making the info public is not a great idea
huge security risk…
for me this is a demo, dummy, I will remove the site anyway…still…not good..
I should not tell all the whys here…
nothing, some user and role management on dnn
http://www.dnnsoftware.com/Content/Dnn.Platform/Documentation/Using%20the%20Control%20Panel/Admin%20Console/Security%20Roles/Understanding%20Role%20Based%20Access.html
for admins and host account, this feature is ok. write SQL and run
but do not provide end users similar feature…can be dreadful
Schedule: different backend task scheduling for DNN
you see the DNN provided classes or classes used by DNN
you can use these classes in your code to implement some DNN like functionality
you can also check if a module use make more sense or not
or you might be able to reuse existing dnn code
You could use other editors Telerik/RAd/CKeditor…
anyway, I can stop here..
I can create another video and short-note on Admin menu
and also another on user management in general…
you are also welcome to create and send to us to post on this site or on our youtube channel

Visual Studio, C# : Why should or should not you use Code Contracts #Root #By Sayed Ahmed

http://programmers.stackexchange.com/questions/211337/why-would-i-use-code-contracts

Why Use?

To avoid null reference exceptions

To avoid critical and costly failure of code/software

However, code may look over crowded, and can be difficult to maintain and extend if you use Contracts.

 

If yours is not a critical application, and in general, failures can never be that costly for you: then you might not need to use it everywhere ().

 

However, be careful in writing your code, deal (address) with the cases where the objects might be null, additionally, properly initialize your variables.

 

Read the page as provided in the url above.

 

Related Tools: If you want to use Contracts, you need to install both of the tools below:

 

https://visualstudiogallery.msdn.microsoft.com/1ec7db13-3363-46c9-851f-1ce455f66970

https://visualstudiogallery.msdn.microsoft.com/02de7066-b6ca-42b3-8b3c-2562c7fa024f

 

That’s right I had to install to work with.

After you install, you will see a tab Code Contracts in the project properties.

 

The useful part:

”

Contracts vs. Null Object pattern

Now this is at least in the same ball park. Languages like Scala and Haskell has had great success with this approach to eliminating null references entirely from programs. (Even if Scala formally allows nulls the convention is to never use them)

If you already employ this pattern to eliminate NREs you’ve basically removed the largest source of runtime failures there is in basically the manner contracts allow you to do it.

The difference might be that contracts has an option to automatically require all your code to avoid null, and thus force you to use this pattern in more places to pass compilation.

On top of that contracts also give you the flexibility to target things beyond null. So if you no longer see any NRE in your bugs you might want to use contracts to strangle the next most common issue you might have. Off by one? Index out of range?

But…

All that being said. I do agree that the syntactic noise (and even structural noise) contracts add to the code is quite substantial and the impact the analysis has on your buildtime should not be underestimated. So if you decide to add contracts to your system it would probably be wise to do so very carefully with a narrow focus on which class of bugs one tries to address.

C# Image Dimension . Keep the dimension as it is when Exporting to Excel #Root #By Sayed Ahmed 

System.Drawing.Image img = System.Drawing.Image.FromFile(@"c:ggsggs Accessimagesmembers1.jpg");

int width = img.Width;
int height = img.Height;

---
Excel and Exporting

When you export to Excel using OpenXML standard
You usually mention where to start and where to end. I.e. cell to insert from and the width/height in number of cells.

Hence, you need to know how many pixels are in one cell for excel (if you want to keep the same height and width)

In general: 
64 pixels on the width
15 pixels on height
(may have an assumption here, Excel with Arial and 10 size font)
--

There are C# Classes and Methods to know/calculate how many pixels per cell.
It actually also depends on some configurations of the Excel file
---
When you use Calibri and 11 size font,
56 pixels on the width
and 17 pixels on height
may work

ideally, you should use code/C# classes to find out (pixels per cell) for the current document.

Still, if you want to use configurations and hard-coded numbers, you can provide the configurations in the web.config file under app.settings using key/value pair.
To retrieve:

WebConfigurationManager.AppSettings["WidthInPixelsForACell"];

Using Kendo Chart; Kendo Chart Events #Root #By Sayed Ahmed

Using Kendo Chart; Kendo Chart Events

Sayed Ahmed

 

One example that helped in real projects

http://demos.telerik.com/kendo-ui/tabstrip/events

 

The example shows how you can execute functionality on different Kendo Chart events. You can see the methods and events mapping as below

$("#tabstrip").kendoTabStrip({
                    select: onSelect,
                    activate: onActivate,
                    show: onShow,
                    contentLoad: onContentLoad,
                    error: onError,
                    contentUrls: [ , "../content/web/tabstrip/ajax/ajaxContent1.html", "error.html" ]
                });

Problem to Solve:
In my case, under a Kendo Chart (actually in an embedded iframe), there were some buttons. The kendo chart had multiple tabs. The height of the tabs were not the same as the contents were different. Hence, because of the iframe height (as was set to the height of the most height tab content - before this solution was applied), the buttons were far off (down) sometimes (if a tab content was not much). I was required to bring the buttons just under the content.

Solution:
Used Kendochart events to resolve the issue, and depending on the tab content height, re-sized the iframe height.

if you use select event, you may see that the buttons are still far off esp. when you move from a more height tab to a less height tab for the first time.  

Activate event helped to resolve the issue.

Another Problem to Solve:
the iframe was showing remote content i.e. cross domain content where I had access to both domains. Used post message communications to send the page height information to the client/parent and from parent/client the iframe size was adjusted. 

Please also check if you need to configure the remote Webserver for allow-access-origin or similar. I did though there were multiple stuff to do on cross-domains; hence, if for this particular case, allow-access-origin is mandatory or not, I need to double check. However, apparently, you need it or you need something similar as even for post message communications, you need to work with both domains.

Anyway, the complete code from the URL is as below as I just mentioned (just in case, the page is not available in future.).


 $(document).ready(function() {
                function onSelect(e) {
                    kendoConsole.log("Selected: " + $(e.item).find("> .k-link").text());
                }

                function onShow(e) {
                    kendoConsole.log("Shown: " + $(e.item).find("> .k-link").text());
                }

                function onActivate(e) {
                    kendoConsole.log("Activated: " + $(e.item).find("> .k-link").text());
                }

                function onContentLoad(e) {
                    kendoConsole.log("Content loaded in <b>"+ $(e.item).find("> .k-link").text() + "</b> and starts with <b>" + $(e.contentElement).text().substr(0, 20) + "...</b>");
                }

                function onError(e) {
                    kendoConsole.error("Loading failed with " + e.xhr.statusText + " " + e.xhr.status);
                }

                $("#tabstrip").kendoTabStrip({
                    select: onSelect,
                    activate: onActivate,
                    show: onShow,
                    contentLoad: onContentLoad,
                    error: onError,
                    contentUrls: [ , "../content/web/tabstrip/ajax/ajaxContent1.html", "error.html" ]
                });
            });
        </script>
