I apologise for posting so many questions here but the first one has stumped me and I thought I might as well add the second.

The first - I have been unable to successfully install the plugin D3Dfunc (found here http://www.dbdepot.co.uk/d3dfunc.html). I extracted the contents of the .zip file into the Dark Basic Professional directory to no avail. Am I missing something or does this no longer work?

Secondly, can anyone pinpoint the issue here:

Somewhere early in the program (ignore main.dat by the way)...



Later, in an attempt to verify the username is correct(password checking not yet implemented)...

ca = checked accounts
ep$ = entered password
eu$ = entered username



I would appreciate any advice.

As for the 3d3 stuff, I don't know.
About your second issue however I think you should access the arrays using simply 'ca' as the index. ca + 1 will start at 1 (ca being initialized to 0) and as demonstrated in your first snippet you stored your user name at the array index 0, leaving index 1 blank.

Ah, yes. Typical careless error of mine. Thanks.

It should - about the only requirement is that you extract with a full directory structure. If you look in your DBPro installation directory and see the DLL there, then that's what you've done wrong.

I think everything has gone in the right place but it simply informs me that the command wasn't recognised.

The file D3DFunc.dll should be in the Compilers\plugins-user directory. If it isn't then it hasn't gone into the right place.

The help file looks like this:

Quote: "D3D INIT : D3D_INIT"


I thought that the one on the left was the command. It was actually the one of the right. Sorry about that; thanks anyway.

The second issue is still not resolved, I'm afraid. I expanded both pieces of code a little:



Therefore, it is only triggered when there are no data files at all to prevent the program overwriting the user's data.

The second part now works, but only if you delete the data files then run the program. If you try and run it again, somehow the array is not being recognised as it doesn't print anything:



Thanks, sorry for the volume of questions and persistent issues.

Not sure if it matters but I always save/load arrays using a 0 in the () I think I remember reading that it needs a number there to Id it

Move the 2 DIM statements to before the IF like this



they will not get executed when the files exist where they are.

Thank you, I will try that.

Is there a need to declare the arrays after loading them? I will try it anyhow.

I think they must be declared before loading.

The definition of an array is usually global - it doesn't matter where in the code the array is declared, it will be picked up and be available.

However unless the flow of execution runs directly through the DIM statement, the array will have no memory allocated to it.
