I need to perform a calculation on one of the fields. It&#39;s too complicated to perform this calculation within InfoPath, I need to write some code in C# of VB (using Visual Studio). That shouldn&#39;t be any problem since InfoPath has a Developer tab with Visual Studio integration. The thing is, it just doesn&#39;t work. Even when I just click on &quot;On After Change event&quot; button and Visual Studio generates an empty function for me, it already produces an error when using the form. Because I didn&#39;t add any code yet, it&#39;s 100% sure the error is not as result of my custom code.<br /> <br /> It&#39;s even weirder. When I create a new empty form, just add a button, and add a skeleton code (an empty function), it won&#39;t work. It just gives a generic code. Is there anything else then just saving what I have to change to be able to use an InfoPath form with code? Or is there some security setting I should change on my computer, or within InfoPath? <br /> <br /> The error message is: &quot;Document Information Panel cannot open a new form.<br /> The form cannot be opened. To fix this problem, contact the form designer.<br /> Form template: https://mysite.sharepoint.com/_cts/documents/e7d9d2651713b7f2customXsn.xsn<br /> Document Information Panel cannot open the selected form because of an error in the form&#39;s code.<br /> Error in the application.&quot;<br /> <br /> I hope I gave enough information. If anything is missing, please ask. Thank you very much,<br /> <br /> Meneer Aart.
