I am using Filechooser, and checked whether the correct file is loaded using the print function until the data path.
text file name: A.txt
self.data_name = str(self.list_data_load.selection[0])
self.fdata=self.data_name
check_error= 'Path' + self.fdata
f=open(self.fdata,"r")
/emulated/0/data/A.txt
#F=f.readline()
but, when I try to use readlines, the app crashes and shuts down in Andorid.
I'm not sure if I need to grant additional permissions to read text files in external storage.
I need some help please.

I hope you are all doing well. I've been recently trying to modify the AutoDesk reference application to allow me to create a heat-map with my own sensors data and my own model. However, I have been having difficulties. Has anyone done something similar before? Do you have to create two separate .env files or do you just change both the credentials for the FORGE_ID portion and the CSV portion in the same one?
Thank You, (I attached an example of what it looks like with only the CSV portion change.)
Changed CSV portion
The .env file must be unique as it is loaded by the dotenv package to add all these values as environment variable (NodeJS access these variables with process.env.[VARIABLE_NAME]).
To ensure your .env file is used by dotenv, you must set your ENV to local, if you look at /server/router/index.js, you will find these lines :
if (process.env.ENV == "local") {
require("dotenv").config({
path: __dirname + "/../.env",
});
}
As you are on MacOS you could try this command : export ENV=local && npm run dev to start your server in dev mode.
The CSV portion you showed should work, just put all these lines into your current .env file and you should be able to use your own model AND add your own sensors data.
If file is dragged and dropped from file explorer it has FileAttributes.ReadOnly flag for StorageFile.Attributes parameter. In that case using StorageFile api to write to file will give error. How to write to file in this case??
In this case PathIO api can be used to write to file (unless file is a system file). Convert data to write into bytes array and then add following code to write to file:
await PathIO.WriteBytesAsync(file.Path, bytes);
This will write to these files without any error. You don't need any additional permission like broadFileSystemAccess for this.
I have a file in my D: drive of my computer and I want to copy this file to an SAP application server so that I am able to see my file with transaction AL11.
I know that I can create a file with AL11 but I want do this in ABAP.
Of course in my search I find this code but I cannot solve my problem with it.
data: unixcom like rlgrap-filename.
data: begin of tabl occurs 500,
line(400),
end of tabl.
dir =
unixcom = 'mkdir mydir'. "command to create dir
"to execute the unix command
call 'SYSTEM' id 'COMMAND' field unixcom
id 'TAB' field tabl[].
To upload the file to the application server, there are three steps to be followed. To open the file use the below statement:
Step1: OPEN DATASET file name FOR INPUT IN TEXT MODE ENCODING DEFAULT.
To write into the application server use.
Step2: TRANSFER name TO file name.
Dont forget to close the file once it is transferred.
Step3: CLOSE DATASET file name.
Plese mark with correct answer, if it helps! :)
If you want to do this using ABAP you could create a small report that uses the function module GUI_UPLOAD to get the file from your local disk into an internal table and then write it to the application server with something like this:
lv_filename = '\\path\to\al11\directory\file.txt'.
OPEN DATASET lv_filename FOR OUTPUT IN TEXT MODE ENCODING UTF-8.
LOOP AT lt_contents INTO lv_line.
TRANSFER lv_line TO lv_filename.
ENDLOOP.
CLOSE DATASET lv_filename.
I used CG3Z transaction and with this transaction I was able to copy a file in the application server directory.
Hi community!
I have an application in VB.Net, in the user's computer is located in program files.
The users run always the program as an Administrators.
But in some cases; when the program try to rename a file in the program files the program throws the following exception:
The given path's format is not supported.
SOURCE = System.Security.Util.StringExpressionSet.CanonicalizePath
Also, happens when I try to copy a file.
The application does the rename or copy automatically and it's the same name for all the users
Example:
Rename(vOld, vNew)
FileCopy(vOld, vNew)
This exception only happen in Win7.
Somebody have an idea what is the reason to some users appear this exception?
This will happen when the user provides an invalid file name, for example one that includes colons.
You should validate that the user-entered file name does not contain any of the values in System.IO.Path.GetInvalidPathChars.
All it's my fault!

I'm trying to rename this path:
C:\_MyFile.xlsx
To:
C:\MyFile.xlsx
In my computer all works fine because I have the both files (The users only has the file with the underscore).
When the program try to validate it try to rename the file "_C:\MyFile.xlsx" to "C:\MyFile.xlsx"
The exception don't give much information about my error...
I ran into this problem when uploading a file with a super long name - my database field was only set to 50 characters. Since then, I have increased my database field length, but I'd like to have a way to check the length of the filename before uploading. Below is my code. The validation returns '85' as the character length. And it returns the same count for every different file I upload (none of which have a file name length of 85).
<cfscript>
missing_info = "<p>There was a slight problem with your submission. The following are required or invalid:</p><ul>";
// Check the length of the file name for our database field
if ( len(Form["ResumeFile1"]) gt 100 )
{
missing_info = missing_info & "<li>'Resume File 1' is invalid. Character length must be less than 100. Current count is " & len(Form["ResumeFile1"]) & ".</li>";
validation_error = true;
ResumeFileInvalidMarker = true;
}
</cfscript>
Anyone see anything wrong with this?
Thanks!

After you upload the file, the variable "clientFileName" will give you the name of the uploaded file, without a file extension.
The only way to read the filename before you upload it would be to use JavaScript to read and parse the value (file path) in the file field.
A quick clarification in the wording of your question. By the time your code executes the file upload has already happened. The file resides in a temporary directory on the ColdFusion server and the form field related to the file upload contains the temporary filename for that file. Aside from checking to see if a file has been specified, do not do anything directly with that file or you'll be circumventing some built in security.
You want to use the cffile tag with the upload action (or equivalent udf) to move the temp file into a folder of your choosing. At that point you get access to a structure containing lots of information. Usually I "upload" into a temporary directory for the application, which should be outside of the webroot for security.
At this point you'll then want to do any validation against the file, such as filename length, file type, file size, etc and delete the file if it fails any checks. If it passes all checks then you move it into it's final destination which may be inside the webroot.
In your case you'll want to check the cffile structure element clientFile which is the original filename including extension (which you'll need to check, since an extension doesn't need to be present and can be any length).
