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...

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 t...
