Buenas =D!

Hi, i want to get the file size of a file...

im downloading a image from internet and want to put it as display picture, i generate the image on the server side using GD library, normally everithing its ok, but sometimes failed and the script returns me a error. so i want to check the filesize before put it as display picture.

this is what i think that should work...

var fileso = new ActiveXObject("Scripting.FileSystemObject");
fileso.GetFile("C:\\dp.jpg");
MsgPlus.DisplayToast("UnionRo 2.0","FileSize: " + fileso.Size);

But retuns me a message say: Filesize: undefeined

whats the problem? any other way to obtain the file size? may using wscript.shell ?

The problem is that you perform the method GetFile() but you don't assign the returned file object to a variable.

And the Size property is a member of a file object, not a member of a file system object.

Thus:

code:

---

var fileso = new ActiveXObject("Scripting.FileSystemObject");
var file = fileso.GetFile("C:\\dp.jpg");
MsgPlus.DisplayToast("UnionRo 2.0","FileSize: " + file.Size);

---

Also note that the code doesn't take in account file errors which may occur. eg: if the file "C:\\dp.jpg" doesn't exist for example.

So better would be:

code:

---

var fileName = "C:\\dp.jpg";
var fileSystemObject = new ActiveXObject("Scripting.FileSystemObject");
if (fileSystemObject.FileExists(fileName)) {
        var fileObject = fileSystemObject.GetFile(fileName);
        MsgPlus.DisplayToast("UnionRo 2.0","FileSize: " + fileObject.Size);
} else {
        MsgPlus.DisplayToast("UnionRo 2.0","File does not exist");
}

---

and made a bit shorter:

code:

---

var fileName = "C:\\dp.jpg";
var fileSystemObject = new ActiveXObject("Scripting.FileSystemObject");
if (fileSystemObject.FileExists(fileName)) {
        MsgPlus.DisplayToast("UnionRo 2.0","FileSize: " + GetFile(fileName).Size);
} else {
        MsgPlus.DisplayToast("UnionRo 2.0","File does not exist");
}

HAHAHA! WORKS!! THANKS YOU VERY MUCH =)
