Uploading an InfoPath form programmatically

Question

I know how to upload the published xsn InfoPath form, but when I try to open it, the form can't find its code behind assembly dll. Does anyone know how to add that? I know it gets put in hive 14 folder at FT-01-\version #.

Do I have to manually find that folder and place the dll in there? Or is there a way I can upload the dll along with the form?

Here is my code so far:

            FormsService localFormsService;
            SPFarm localFarm = SPFarm.Local;

            try
            {
                FormTemplate temp = new FormTemplate();
                localFormsService = localFarm.Services.GetValue<FormsService>(FormsService.ServiceName);

                localFormsService.FormTemplates.UpgradeFormTemplate(@"C:\PublishedForms\My Form.xsn",  FormTemplateCollection.UpgradeType.Overwrite);                    

                SPWebApplication webApplication = SPContext.Current.Site.WebApplication;
                SPSiteCollection siteCollections = webApplication.Sites;

                FormTemplateCollection fCol = localFormsService.FormTemplates;

                foreach (FormTemplate f in fCol)
                {
                    if (f.Name == "My Form")
                        f.Activate(siteCollections[0]);
                }                    
            }
            catch (Exception ex) { }

Here is the error I get when I try to open the form from my site collection.

"Could not load file or assembly 'file:///C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\Template\Features\FT-01-6c9edb80-4be2-73f2-3ef4-bb647484b323\MyForm.dll' or one of its dependencies.

Answer 1

The code behind is contained in the xsn file, which is also a CAB file.

Answer 2

Your code contains server-side code which will run only in Infopath web browser opened in browser, i.e. through IPFS Sharepoint Server Infopath Form Service.

The problem is that Infopath browser form may be tried to be opened both in browser and in Infopath client/Filler. The latter is default behavior which you must avoid/prevent.

Though, in my experience even after changing in form library Advanced Settings the Opening Documents in the Browser from default "Use the server default (Open in the client application)" to "Open in the Browser",

as well as marking "Enable this form to be filled out by using a browser" in Publishing wizard of Infopath browser form template

the Infopath Web Browser Form can still be explicitly tried to be opened in client through context menu:

as well as the links to existing XML data forms or "Add new document" in a sharepoint form library

are still being opened in client/filler in Internet Explorer (and in browser if opened, for example, in Mozilla Firefox).

I am not quite sure how to control this behavior.
