Hi, I am new to app inventor. Is there a way to get a list of directories / files of my web server and show every image file I find into a different image component on my screen?
thank you
the ftp extension and its RemoteFileNames method is able to provide the filenames of a remote directory
there could theoretically be lots of images on your server... therefore let me suggest to create for example 10 image components together with a forward and previous button. Display only 10 images and after clicking the forward button display the next 10 images etc. same with the previous button...
A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
