Save few Images, upload them file by file and then delete them

[wikki74]

@TIMAI2

Then just rename using blocks

I already tried it but got a lot of errors like "image does not exist" eg

[wikki74]

@TIMAI2

Your original blocks would overwrite images if you did a second run of the app, because you would start at 1 again.

That doesnt matter, as soon as they are on the server (with special name containing date and time of upload) i do not neef them any more on the device

[TIMAI2]

Looking at your upload url, it appears you can set the filename on the server, regardless of the name of the file you actually upload ? In which case, changing the filename to your "special name" should be trivial ?

[wikki74]

You are wright, I can set names at Server, Thank you !!!!

[wikki74]

It is working, thank you very much Tim.

[wikki74]

I have to come back again to this....

Is there any possibility to view the taken images alltogether before uploading?

They are not showing in the phones Gallery....

[TIMAI2]

You could try this:

Image Grid with HTML

Dear Tim,

Thank you very much again for your help (will make a contribution to Liveboats )

I solved it using this one:

ListView CreateElement method use

Worked perfectly as advertised. I think since I was pulling the image from storage that I needed a full path definition (including the file: protocol). [Capture] The image files are taken from the /Pictures/ directory in the Apps file scope. The file name must be fully expanded for the image reference to work. Note that if you want to delete the file, then you want to reference /Pictures/[filename]. So for example, image picture file name for the ListView CreateElement is file:///storage/…

Thanks also to @Mark_blouzoopa for the blocks!!

Last thing I have to do now is to delete all images stored in /Pictures/ (so all images taken by the camera as I do upload them to my server, so i do not need them any more on the device)

Is there any way to delete ALL files in this directory?

The File component uses / needs a → relative path:

but you use a → full path:

What is the DefaultFileScope in the Designer?
(apparently not "App")

[Anke]

Try this:

[wikki74]

Hi Anke,

It is already set to App (see screenshot)

[Anke]

@wikki74

It is already set to App

Yes, looks fine, but I'm talking about DefaultFileScope!
Anyway, try what I suggested.

Same, it is showing "Sorry, file to delete does not exist"

I have attached the aia file
ListViewWithDelete.aia (35.5 KB)

Yes, all the "fiddling" with relative, absolute, full paths and paths redirected to the ASD (depending on the FileScope) is really confusing.

Even for me from time to time, until it has been sorted again.

[wikki74]

I totally agree

However, thank you very much for your help and solution !!!!!!!
