Hi,

One great thing featured in 4DOS/4NT scripting is the ability to create
variables out of other variables...

Ex.: the next code (for 4DOS)

Hi Lucyfer,
I think you are refering to Variables that are actually Arrays. I have always used VDS List's in place of Arrays.

mindpower:

Arrays could well do it, but we are kind of limited in lists, you see...
I won't be using lists above 9 'till the debug window is fixed, 'cause right now we can't monitor lists 10 to 16 even is these are usable...

Of course, now that i've learned the existance of the second option of @item(), I will certainly give it a second thought and optimize some code... Wink

Thanks, this was helpful!

Hi Lucyfer,
You can go above List 9 just by making hidden listboxes. If you add a listbox and hide it then you can call the list by name. Also there is a DLL called vdsaray.dll here on this forum. I think that Tommy has released a DLL that will give you unlimited number of list's as well.

The point he mentions though is that with any of the alternatives, the
list contents cannot be shown in the debug window in the VDS IDE Sad

Have you tried adding lists like this instead of hiding them?

DIALOG ADD,LIST,L1,0,0,0,0

Hi!

Tommy got it right, those can't be viewed Sad

. I used hidden Editboxes as arrays before (needed 6 locations..) and lists. It's a way of getting some intelligent variables names.

As every programming text/book are trying to teach, we must always use intelligent variables/labels/... it's a bit different with VDS I guess.. Wink

Tommy: What about a dll-gateway dll? I'd like to compress files with, say, info-Zip (so I can distribute it..) but I don't think I can access those kind of dlls using EXTERNAL zip.dll... You see? This would be cool!...

Bye

I tried, and couldn't manage to make one. Sad

I think it involves coding
pieces in assembler, which I'm not familiar with. Also even if some calls
could be made to work, others may not, as VDS for example doesn't
have the ability to create structured objects.

Maybe Mindpower's API calling DLL is something to wait for for you...

Best regards,

Tommy

Hi All,
BTW Lucyfer yes you would be able to make a little debugger that could monitor VDS listboxes or editboxes everytime an item is added using my Gadget... I am going to release the freeware only version as soon as I get my webserver up and working so everyone will have a chance to play with my gadget dll. Since Mr. Garrett is going out of business and I was on his server Sad

Actually Tommy and everyone else. I have been looking at making a DLL for both Info_Zip and MS *.cab's....I figured out how to handle callback functions in VDS DLL's when I built the messaging API piece of my gadget dll so I think it would be possible to do it. I am not going to make Info_Zip's or MS's Gab's compression a part of my gadget dll because then I would either have to wrap both of Info_Zip's zip32.dll/unzip32.dll and MS's cabinet.dll into my gadget dll or make people carry those dll's with my gadget dll. So I am going to build a seperate DLL for doing just that. My gadget dll will have some low level compression routines built into it but as purely beta/research functions and commands. One of them will be the Huffman encoding algorythm and the other one will be the LZ compression algorythm. This may allow for some smart VDS programmer out there to build our own compression/archiving system Wink

So who knows....
