Hello everyone, I am new to the forum.

I currently have an attribute which is a list. From this drop down menu, I can only access around 100 options (ELog restriction I think). How can I extend my drop down list to say 200?

Example:

Attributes = RB

Options RB = a, b, c, ...,etc.

The number of 100 options is defined in elogd.c with

#define MAX_N_LIST  100

You could try to increase this to 200, but I have no idea if you will hit some other memory limit then. So what about conditional attributes? You subdivide your list into several smaller lists, like

Attributes = Category, RB
Options Category = Cat1{1}, Cat2{2}
{1}Options RB = a,b,c,d...
{2}Options RB = e,f,g,h,...
this is then also easier to handle, as compared to select a value from a very long list.

 

Stefan,

Thanks for that advice. I have made that change to the elogd.c file, but the only problem I don't know how to compile Elog to make that change take effect. I did the stop and restart of the elog  service in windows, but that made no difference. How do I compile ELog? Sorry for my ignorance, but I am fairly new to Elog.

You need a C compiler to compile Elog under Windows. If you don't have one, I would suggest to follow the advice to use conditional attributes. This does not require a recompilation of Elog.

Stefan,

I can get my hand on a C compiler. What the process involved?

Thanks,

Paul

 Sorry, but teaching you how to compile C programs is beyond the scope of this forum. Please buy a book for that. Most C compilers also comes with some decent documentation. You might try gcc under cygwin or Visual C++.

Stefan,

Thanks for your help. Will get back to you on how compiling the program went.

That was never ment to work. But I found some time to implement it. If you
download elog255-4.exe from today it whould work. Let me know if you have
problems.

Thanks a lot for fixing this issue, especially as it was never planed. I will
test it on Monday afternoon and will give you a reply.

Hello Stefan,

the changes I asked for, are working as requested. The extandable options are 
inserted into the correct line of the conditional attributes. 

  Thanks.

PS: While testing on a new demo logbook, I first made the mistake to declare 
both options, the first one and the related one as extendable. But I can imagine 
that this was really never ment to be implemented.

Actually it was never foreseen to have extendable options in the [global]
section. I added now this functionality. The new windows version can be obtained
under
