Working with dialogs in NRapid

In this post I’ll cover the basic usage of dialogs in NRapid, how do they work and what kinds of controls do we have available.

As we already saw, to create a dialog we have to add a nested class named "Dialog" inside a report. In order to add controls, we need to define properties in that class, and based on the properties type, the report engine will create and add the controls to the dialog.

This mechanism is pretty much based on conventions, but we have some attributes to annotate the properties and modify the default behavior.

This post is on basic usage of dialogs, so combos and autocompletes are off the table, because they requires a bit more of configuration.

And then when we run the report we get this

As you can see in the output dialog, one of the engine conventions is “first defined, first served”, but sometimes this is not the desired behavior or you maybe want to add columns or change the text on the labels or stuff like that. To do that you can use annotations:

And when you run the report, you will see that the output has been modified:

This is just a sneak peek of how to work with dialogs, will be upcoming post covering combos, autocompletes, validations, calculated props., and many more. Stay tuned!

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...

Printing html using the embedded web browser control

In this post I’ll try to answer some questions about the web browser control and provide some workarounds for known issues involved in the printing process. I'm assuming that you have some experience with the web browser control and basic knowledge of COM and hosting APIs. So I’m not going to cover those topics. At the bottom of this page I’ve added the links to download a small library I wrote that takes care of printing HTML and a demo app so you can try it out without having to write any code by yourself. Using the code The HtmlPrinter class will allow you to print html from an URL or just passing the html as string, you can also specify the title and the number of copies you want to print. The code may look something like this: Now that we know how to use the API let get answer some questions. Why my app crashes when I try to print multiple copies of a page? Well, apparently when you send a lot of print commands to the web browser control, ther...

Migrating an ASP.NET MVC 4 app from Azure websites to WinHost

About a week ago I've to migrate an ASP.NET MVC 4/EF5 application from Azure websites to WinHost. While the process was really smooth, there were some caveats related to database connections that I want to share with you. Create and setup the ftp profile on VS and configure the connection string was really easy, WinHost provide you those values and there is nothing special here. But once you deploy your website and try to see it online, you may get the “yellow screen of dead” with the message: "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)" Assuming you wrote the connection string properly, this happens because you cannot use the default connection name in your web.c...
