append to text file

Anonymous User — Fri, 14 Aug 2015 02:22:42 GMT

Might be a simple question.... in the QML extras there is the FileFolder object, which has methods to write to file or text files. But they seem to just overwrite any existing file - is there a way to append instead?

FileFolder{

id: myfileFolder

path: "c:/myfolder"

}

myfileFolder.writeTextFile("myFile.txt", "my message to add")

myfileFolder.writeFile("myFile.txt", "my message to add")

Paul,

I am not familiar with QML, but saw you hadn't received a response, yet. I perused the API reference - ArcGIS Runtime QML Extras: FileFolder Class Reference - but couldn't see anything that natively supported appending to the file. This is a really basic feature - I'm surprised it's not something made available to you.

As an alternative, how about reading the existing text file using the readTextFile method, appending it yourself, then calling the writeTextFile method with the full string object?

Hi Chris - yes, reading, adding to and then re-writing the whole file seems to be the solution in the absence of an append method.

Cheers,
