I'm having trouble with errors - every time I try to use HTTPSocket methods, I get errors telling me that the method or property does not exist. I'm trying to write a program that, once you hit "start", continuously downloads a url containing an xml file every 10 seconds or so.

I copied this straight from a readme, put it under the "start" push button's action, and I get the same error. In fact, it seems like I somehow am missing methods, because for both the HTTPSocket and the HTMLViewer the language reference lists methods that do not appear when I start typing mySocket.methodname, and attempting to use them throws the same DNE exception.

So, here's two lines of code that are supposed to work and do not - can anyone tell me why I'm getting this DNE error? Thanks (again!):

Dim socket1 as New HTTPSocket
socket1.Download "www.realbasic.com/release.html", GetFolderItem("RB release")

socket1.DOWNLOAD???

There is no such method. I think you want socket1.Get.

Note also that autocomplete is context sensitive. For example, PageHeaders returns a value, so if you just type

socket1.PageHeaders

it will not autocomplete, but it will if you type

dim phdr as InternetHeaders = socket1.PageHeaders

Thanks for the tip about autocomplete. I copied the download method straight from dan vanderkam's readme on httpsocket 2.0, but maybe it is outdated.

Had to google that. Yes, that is very old. It looks like it predates the built-in HTTPSocket class. No wonder that documentation doesn't match the existing control. RS has since made their own class. Use the official documentation.

Figured I'd reply here with another question...

I've got a push button whose action is DIM f as FolderItem f = getFolderItem("tempData.txt") Object1.get("myURL", f)

and an HTTPSocket whose DownloadComplete event is

dim i as integer i = ticks while ticks - i < 5 * 60 wend

DIM f as FolderItem f = getFolderItem("tempData.txt") Object1.get("MYURL", f)

I added that 5 second pause because the data was flickering in and out out. So, now what happens is that there is data for 5 seconds, then an empty text file for the next 5 seconds, then updated data for another 5 seconds. Rinse and repeat.

I can't figure out how to stop the file from flickering empty and then full of data. I've tried looping under the push button's action, but that just doesn't update the data.

Any ideas?

Here's a Gist with the code for better formatting.

The [ code ] tags are your friend:


Seems like a roundabout way of doing things. Why not just put a timer on your project with the period set to 5000 (5 seconds). Then put this is the timer's action event:


The above worked for me when I tested.

Oh, thanks. I will try that!
