Working with unattended reports

In this post I‘ll show you how to create reports that NRapid will execute into an unattended mode. I strongly recommend using this kind of reports in automation scenarios only, and let the user see the print preview dialog in the rest of cases.

The only difference between this reports and the standard ones, is that you will cannot make use of dialogs, the runtime will always pass in empty views to the ConfigureReport method. The ConfigureReport method will be executed, but you will have to grab the arguments from somewhere else. The execution pipeline is the same that NRapid uses for standard reports.

This is the code to print out the whole list of categories in a dialogless mode.

Notice that this report inherits from UnattendedReport class, this class tells to NRapid “run the report unattended”. Also notice that this class comes with a convenience method to configure the report with no arguments. You still can override the one that gets the view data but you will always get an empty view.

Execute this report and it will be printed out in your default printer.

As a side note, 
Yes, we are using the embedded WebBrowser control, and yes, it is possible to print html without showing the print preview dialog. ;)

How to create MS Word documents from Office templates using C#

The OpenXML SDK allows you to do pretty much anything you want with office files such as Excel, Word, etc… While many people like this library, I found it complex, unintuitive and poorly documented, not to mention the awful xml format that uses under the hood to represent the documents, styles, etc. So I decided not to use it and build my own solution. If you, like me, don’t like that library, you will find in this post an alternative approach to build word documents from templates using c#.
A neat trick to work with Office is to use the macro recorder to understand how things work. The macro recorder allows you to start a macro, do something by hand, stop it, and then take a look at the generated VBA code. Once you do this, you are pretty much set.
This is how it looks the template I’am going to use.


Note: save the file as a Word template (.dotx)
This is the code to create Word documents from C#:

By running the code, you should get a document that looks like this.

WinForms, paging the DataGridView the right way

I know this may sound like old history, but in the enterprise world there is still a lot of WinForms development. Just a couple of days ago, I had to implement a custom DataGridView capable to work over a butt load of data (100K+ records) and keep responses times acceptables.
I thought paging will be a good way to go, and as WinForms is pretty old nowadays, I supposed it will be easy to find a couple examples on the web.
While in fact I found examples, all of them were incompletes and/or they wouldn't perform well in real world apps... So I decided to roll my own component and post it online. Hopefully, someone else will find it useful ;).


The bread and butter of this solution relies on LINQ and deferred execution. As LINQ takes care of all complicated work, it was quite easy to implement.
This component also supports conditional format, sorting and some search capabilities, but in this post I will concentrate on paging only (I'll cover the rest of the features in future posts)…

How to replace text with images on Word documents using C#

This post it’s a reply to a question I got from a previous post that shows how to work with Word templates from C# code. If you haven’t read it, I recommend to do so because I’m not going into details here. But basically it was about how to create a Word document from a template and perform same text manipulation.
So, the question from Marcel Kieboom was
“Do you know if it would be also possible to replace one of the words with an image which is locally stored?”
The answer is yes, and this is how you can do that.

Based on the same convention I had used in the previous post, I should have a template like this:


What I’m trying to do here is replace the text [angus-young] for an actual pic of Angus. The technique I’m using it’s pretty common on web sites and basically consist in have an image with a matching name for each keyword I want to replace and then create the image path dynamically.
This is the C# code to do that.


* When I execute the find operation I’m using the flag WdReplace…
