Hello! I'm new to the Forums, but not to VDS. I love VDS! Over the years, I've silently watched it grow. Anyways, I have a question,

I am trying to append something to a variable. Ex.

%%ThisVar = John

%%ThatVar = Doe

%%Another = 203994

What If I want %%ThisVar to = JohnDoe203994

%%ThisVar = JohnDoe203994

I would like to know how to keep appending something to the end of a var. I tried

%%ThisVar = %%ThisVar%%ThatVar but didnt work. Any ideas?

Thanks Alot

Could it be @STRINS ?

[Skit3000]

You mean something like this?

[citosoft]

Basically Yes, I just want a loop that will continue appending chars to a var. For example, i am using a BINFILE operation to read each char at a time of a file, i want what it reads, to be stored into a VAR using a loop. Something like this


%i = 0
%%POS = 0

Repeat

%%POS = @SUCC(%%POS)

BINFILE SEEK,1,%%POS

%%READ = @BINFILE(READ,1,TEXT,1)

%%COMP = %%COMP + %%READ <--- ? Course this isn't Visual Studio lol

UNTIL @EQUAL(%%READ,&)

Eventually, the & char is the delimiter for telling me when the end of a LINE of information is. So What I want, since BIN FILE is reading character for character, I want to keep appending the characters it reads to a var. Hope this makes sense.

Thanks

%%ThisVar = %%ThisVar%%Name1%%Name2%%Number


This cause one huge variable name to exist

%%ThisVar%%Name1%%Name2%%Number <-- This would be one long variable name rather than appending each variable.

citosoft,
Here ya go... You don't need the + sign just stick the 2 variables together.

[citosoft]

When I do that, it detects %%COMP%%READ as one big variable tho? Should %%COMP = something first, cause initially %%COMP is empty.

At least the debugger shows %%COMP%%READ as one variable name

Anyone interested in making a custom DLL for me with a simple database like function ?


Nutshell: (What I need)


DB WRITE,92039
DB WRITE,93003
DB WRITE,02939

%CHECK = @DB(EXIST,92039) ; Does this record exist?

Thats it.. simple and sweat. Willing to pay, but needs this within 2 days.

citosoft,
The code I posted to you before works. I just tested it. Here it is again as an attachment. The reason I did the %%COMP variable like I did is so it can have a memory address before I try to assign it to itself. VDS will treat it as a empty string.

Yes I am aware of the LIST functionality however, I need to use a static DB on file somewhere to check against. Reason is because there are records for example that are being PRINTED in my software, and we want a DB on file to check against to determine if the record was printed already or if it is an updated one. I could always use INI which is fast, but not great in larger DB sizes like 20MB - 100MB etc. I was looking a the SQ3 LIte but it looks a bit much for what i need. Not sure yet. But a custom DLL would be GREAT !

Hey we're willing to pay simply because we are limited for time. Let me know though if anyones interested. Thanks for all the help also. I hope we'll get well acquainted here.

citosoft,
There are 2 commands in my GadgetX.dll that may be what you need. The commands are the Dictionary and the BinList commands. Basicly they are similar to the VDS list commands but they are on steroids. The Dictionary command is a highspeed lookup table similar to a INI file. The BinList commands are almost exactly like the VDS list but able to load really large amounts of data. Both commands are more than capable of handling small files like 50 - 100 MBytes. The dictionary commands will give you the fastest lookups but it does not have all the fancy commands and functions as the BinList command does.


shameless plug

Yes, I've taken a gander at your site. It looks interesting, but will it make for easy syntax and is it stable ? Will the program run on Server 2003 also? And lastly, will it make for easy syntax?

Assuming it also writes to a file rather than memory?

Thanks.

[vdsalchemist]

To Answer your questions...

The syntax is IMHO as simple as VDS. However I have been using VDS since version 2.03 so my knowledge of VDS and the GadgetX.dll is a bit more than others.

Yes I use it every single day on Windows Server 2003. The DLL has been throughly tested with the following versions of Windows... Win9x, WinME, NT, Win2k Pro, Win2k Server, Win2003 Server, WinXP Home Edition, and WinXP Pro both SP1 & SP2.
I have not tested the DLL on the following versions of Windows... Vista or WinXP 64 Pro. There is no technical reason why it should not work on these OS'es but I don't own them so I have not been able to test the DLL on them.

Yes I would consider the DLL to be stable. I use it everyday in my daily job as a Application Performance Analyst where I require the abilities to test Enterprise level software. The DLL is used to build supporting utilities and to manage large quanties of data.

Also I have provided 4 to 5 different ways to contact me. Registered users have access to a support system where you can submit trouble tickets and monitor the work on those tickets. Registered users also have access to the Message board where they can submit a wish list or discuss how to get things to work.

Below is a code snippet from one of the included examples using the Dictionary commands and functions.

I like all the extended functions, but tell me directly though, does it write and store the information to a file? Sorry If I've mis-understood you. If the application closes and re-opens another day, will the data still be accessible?
