today I upgraded to 2019R2 and my previous applications HTMLViewer have all stopped working. With just simple code:
dim theHTML as string = theOrder.ReturnOrderItems_HTMLView(currentOrderIDinBatch,ShowOnlyFilter) detailsView.LoadPage(theHTML,SpecialFolder.Temporary)
where detailsView is an HTMLViewer and theHTML string is just some html to display.
The HTMLViewer now has an error (“Navigation to the webpage was canceled”) and no temp file is generated in my Temp directory. If you right click on the HTMLViewer and go to Properties, it has a file url to my Temp directory to a temp file that does not exist. It’s almost like Xojo cannot write to SpecialFolder.Temporary anymore.
I have included a screenshot of the application in operation, along with the htmlviewer showing the error, and the right click-properties showing the Address to a file that doesn’t exist in the Temp directory.
Please note that this worked perfectly in 2019R1.1 and for many years before. I read the 2019R2 release notes and I don’t see anything about HTMLViewer’s functionality changing.
