@Craig G I am aware you can now use this in 2019R2 but is there an earlier equivalent?
f = FolderItem.ShowOpenFileDialog( jpegType + pngType )
Yes, you can do the same with Filter; but I don't think it circumvents the file type listing on the open dialog. Does 2019r2 / your method do something different? Can you humor me and post a screenshot if so?
dim tod as new OpenDialog
tod.Filter = pngType + jpgType
(assuming you've made pngType and jpgType)
@Sam Rowlands Will allow your user to select any kind of image file that the macOS can open.
The "user must select the type first" is a user experience
failure of Windows. ;)
