InfoPath Dev

I am creating a custom class which handles commonly used functions throughout multiple, seperate, forms. I hope to simply be able to create this class once, drop it into a project, and be able to use the functionality of it. Unfortunatly I don't seem to have access to the same objects that I do in my FormCode code-behind.

To eliminate some of the issues, I added references to all the data my main form is using, but I simply don't know how to access my main forms xml. I'm not even sure what object, if any, I need to call to be able to use my main forms data sources. I don't even have a DataConnections object availible.

For instance, when the form initally gets loaded, I call a class which maps my data connections to certain fields. Unfortuatly, there is functionality missing that would allow me to use a generic class.

Does anyone have any experience with using custom classes/dll's within Infopath?

Hi Biovox and welcome,
Can you pass a pointer to your thisApplication or thisXDocument?

I'm not completly sure. Do classes have access to the datasources that the manifest document uses?

Hi Biovox,

We also have a Common class, which we are working up to release to the public before too long. Here's the steps we use:

1. Add Common.cs to current InfoPath FormCode project.
2. Change namespace in Common.cs to match that of the FormCode class
3. Create a private global 'c' variable of Common type
4. In OnLoad, call c.Init(x,y) where x is thisXDocument, and y is the string of all XML namespaces found in the form.
5. When using common functions, call c.CommonFunction().

Hope this helps!

Where are you getting the thisXDocument from. It's not in my availble list of objects with my current name spaces. Also - I am using web only enabled features.

Are you using the InfoPath 2007 or InfoPath 2003 object model? If you are using managed code in IP03, you should be very familiar with thisXDocument... therefore I'm assuming you are using IP07.

2007

IP2007 uses "MainDataSource" instead of "thisXDocument"... You will need to pass in that.
