File Upload - determine size

[Former Member]

Hi Gurus,

i use in this time the fileupload UI element - after choosing a file I developed a upload action with following code:

byte[] file = element.getStorage_place();

double kb = file.length * 0.0009765625;

if(kb > 5000){

...Message...

}else{

}

The problem, i cann't calculate the size after uploading the file, which takes many minutes if you choose a file with a size over 10 MB.

To avoid the timeout, i like to determine the size before uploading - is there any possibility?

Thanks in advance Stefan

Hi Vito,

the problem, the ui elements returns only the filename - how can i get the directory?

Stefan,

please check the API regarding IWDResource:

Note that you can use getUrl to get the URL, so also the directory.

Hi Stefan

follow the blog Kanwalpreet indicated to you, that's cool. But if you want to ckeck the file size beforeupload use this code:

.....

f = new File(directory, filename); // Create a file object

in = new FileReader(f); // Create a char stream to read it

int size = (int) f.length(); // Check file size

if (......) //Here go ahead with your considerations regarding file size

.....

Thanks,

Vito
