Hi,
I dont know if this subject subject has been treated before. But if it serves for somebody:


Structure mystruc
mylong.l
mystring.s
...
Endstructure


*struc.mystruc = Allocatememory(sizeof(mystruc))
*struc\mylong = sizeof(mystruc)
*struc\mystring = "Loaded dato on the string ...

the number of threads is dynamic.


in this case you can use a macro for create the structure, like this:


macro create_struc(trheadid)
Global my#threadid#data.mystruc
callfuctionfast(dlladdr, @my#threadid#data)
endmacro
(I'm not tested it with structures, but I'm use it with strings and ...

Hi, my approach:

1.In every thread:

structure mystruc
mystring.s
endstructure

Global my{threadname}data.mystruc
....
callfuctionfast(dlladdr, @my{threadname}data)


2. In your DLL

structure mystruc
mystring.s
endstructure

ProcedureDLL Uppercase(*pointer)
*pointer\mystring=Ucase(*pointer ...

I think I've solved.
Use this code after your "mysql_fetch_row()" statement:

nf = 0
ini = peekl(*row)
debug str(ini)
lon=0
Repeat
new.l=peekl(*row+(nf*4))
if new = ini+lon
debug str(nf)+" : "+ *row\field[nf]
lon + len(*row\field[nf]) + 1
nf + 1
else
break
endif
forever

It checks if ...

it can parse for rows and fields without any count-like function.

You're using "field_count.l", a subfield from MYSQL_RES structure. My problem with it is similar to use "mysql_num_fields()" when I query to DB in a previous program: I need to send it to DLL.

In the DLL I've only the *row pointer ...

I've tried it.
It produces a windows system error when it reach the end (out of memory, I suppose). I dont have a chance for testing the end+1 element.

I know mysql_num_fields(), and I use it.

But I need to use the fields array in a DLL who can't connect to DB.
Of course, I can send num_fields as a parameter to DLL, but I would to avoid it because the DLL is used in a lot of processes.

If there is no another solution….

Thanks, Flype.
Unfortunately, my program source is mySQL.
It returns a *row pointer to an C-array (1 based).

I've tried your trick, but it seems that it dont work.

Hi,
I've received in my program an array dimensioned in another program or process. (its memory address, of course)

It's possible to know how many elements are dimensioned in the array?.

many thanks.

I dont have any doubt...
But it's a part of a spanish joke. (impossible to say it here).

And StringField(String$, Index, Delimiter$) ?
And ReplaceString(String$, StringToFind$, StringToReplace$ [, Mode [, StartPosition]]) ?

Both commands are also used alot.

Well, you can type
"Select * from myTablename where concat(myField, myField1, myField2, ...) like '%WhatToLookFor%' "
(or "... contains 'WhatToLookFor' ", if permited in database syntax)

Hi,
I need to use an example from Freak , about "Gadgets in DLL"
http://www.purebasic.fr/english/viewtopic.php?t=6339

but at compilation, POLINK says "Unresolved external symbol _PB_Gadget_ObjectsArea".

I suppose it has changed in PB4. What is the new symbol for gadget list?

JOAQUIN

Hi srod, a little suggestion:
All function names on egrid starts by "egrid_...".
It's inconsistent whith PB commands terminology, who never uses underscore, my proposal is to delete it.

Good job.
