Hi!

Now i`ve some nice questions to you :

1) Can i connect directly to the Internet from VDS without opening the Browser?
(for example: When you have a list and like to merge items from a txt File at the Web ; http://www.myserver.com/data.txt -> local list)
2)Can i download a file from VDS without opening a download-dialog or browser?
(for example: When you have a file,that you would download with VDS Application from the Web,like a download-manager)

So,this questions aren`t really easy to answer,but i really need this features for my projects!

Good Night!!

Hi Thomas !

Well, there are many options on this one.
Either use the VDSIPP DLL which has support for up to 99 threads and supports both HTTP and FTP and more and Tommy's VDSDLL also has this functionality, but I would suggest using the VDSIPP since you can download to an internal buffer (ie. not a file) in then process this buffer as a list

Hope this helps !

Another important question:
When you`ve loaded a list from a text file and want that an event occurs when you`ve selected an item.How can a do that best??
I think i can load a string from the header of the textfile that should not be showed in the list,can i do that(This is also the best way for my Programm)?

PS:It`s a dynamic list!

Hi Thomas !

Use the CLICK or DBLCLICK style on the list dialog element

and then add this event handler:

:LIST1CLICK
info @item(list1)
goto evloop

Is this what you want ?

If you add a CLICK style to your list like:

Yes,that`s possible SnarlingSheep , but i need to read text from a textfile for this!
Is there any way?

Henrik · Posted: Tue Mar 26, 2002 2:56 pm Post subject:

Hi Thomas !

You could just parse the list item first:

Assuming your list item is ;goto item1
option fieldsep,"o "
parse ";%%ITEM",@item(list)
option fieldsep,
goto %%ITEM

Hope this helps

Thomas233 · Posted: Tue Mar 26, 2002 3:36 pm Post subject:

Yes Henrik,this is also a way but i really need to read text from a textfile(or Datafile) also for this,because it`s a dynamic list!

I thought you already knew how to read from a text file. You can use:

Hi Thomas233,

I noticed you mention "Dynamic List" several times. I wanted to ask you, is the content of the list dynamic while the number of items is static, or are both content and number of items dynamic?

You also mentioned that when you "select" an item from the list that you want something like a "goto item#". Looking at this I am assuming you mean you want this to go to a label called :item#. Is this assumption correct?

If the number of items in the list is dynamic then having labels of the ":item#" format could be a problem.. not really a problem, just more work. Here is one way I can think of to do this. You would probably need to find the max number of items you will ever get in that list and make a set of labels going from :item1 all the way to :item(max number). This would make your code(in VDS3.5) look something like this:

Hi Thomas233,

I could be wrong, but this almost sound like as if you want to create an app in VDS that will act like an interpreter or executer or something with the external file acting as a script. If I am right in this assumption then I am not sure how you can do it. I have never done it. I guess it's possible to build all your routines in the app and have them called from the external file using a system of tags or flags or something.

I am left with asking what is it are you trying to do that you need individual labels per list item? Will they be doing different things or can they be consolidated to one or a group of routines?

The only other thing I can think of is to go back to the original example I had in the earlier post where you try to anticipate what your max list item number will EVER be and build labels accordingly using @index() to move around.

I'm sorry I don't have anything else at the moment. If I come up with an idea, I'll let you know.

Hi Thomas !

A long time ago I wrote a small interpreter in VDS to parse lists and offer mainly list manipulation but also with support for contrrol structures and more. I can email it to you if you like
