I am new to xojo and have already familiarized myself with a small project. Currently I have encountered a problem where I unfortunately don’t know what to do next.
The problem: In my desktop app I download an image from an URL and then want to load it into a specific canvas. There are about 20 different canvas in my project. This is because i want to load different images into different canvas.
When I now assign the image using MainCanvas.backdrop, unfortunately no image appears.
The following Code works, when i open the FileDialog an select the image.
// THIS WORKS // Get filename from URL Var con as New URLConnection Var url As String = "https://MyUrlToMyPicture.jpg" Var filenameLength As Integer For i As Integer = url.Length - 1 DownTo 0 If url.Middle(i, 1) = "/" Then filenameLength = url.Length - i Exit For End If Next Var filename As String filename = url.Right(filenameLength) Var downloadFile As FolderItem = SpecialFolder.Desktop.Child(filename) con.Send("GET", url, downloadFile) Var picFile As FolderItem picFile = FolderItem.ShowOpenFileDialog("") If picFile <> Nil And picFile.Exists Then Var pic As Picture pic = Picture.Open(picFile) MainWindow.MainCanvas.Backdrop = pic End If // This works NOT .... same code as above ...... Var picFile As FolderItem picFile = downloadFile .... same code as above ......
I don’t get it. Why does the picture not loading into my canvas?
Can please point me someone into the right direction please?
Thank you in advanced.
