the problem is i can only use one storage-class specifier, but static is required so i can't use extern. this current method works fine if i only need to access it through one source file, but my project has many source files and requires the members of this union to be accessed through many of those files. here is my current code, please post yours that works:
extern union {int y; int z;};<br />
<br />
#include "main.h"<br />
<br />
void do_something() {<br />
y = z;<br />
}<br />
<br />
static union {int y; int z;};<br />
<br />
void main() {<br />
do_something();<br />
}
i appreciate it,
John

why using an anonymous union ?
just give it a name !!
extern union myUnion {
int x;
int y;
};

Giving a name is good.

issue , i tired and checked it out in my
project.
It works fine .

that was not so bad,, except the little "je fais bien" instead of "je vais bien", but nevermind.
VivekuniQ wrote: how's chirstmas preparations going on ?
full of work !!!  actually, i'm still working until late friday evening, but i took time to buy some presents to my mum (who comes to see me and celebrate Xmas with us this year - she have to come accross 800kms to get here !), my sweet girlfriend and all her family in which i will pass the date (sisters, parents, boyfriends of her sisters too - which have the same first name as mine !!  what a coincidence !)
VivekuniQ wrote: is it full of snow?
not where i am actually... i love snow, i love skiing, but i am near the atlantic (Nantes i you know), and snow if quite rare out there...
VivekuniQ wrote: spend lot of time with your coupine??
hum, not that much, but i'd like to !!! it's hard to find the time to spend with her when i work hard all the day, when she also have to study hard for her exam on january, and when we don't even live together during the week !!  but hey, it's hard now to be better latter, isn't it ?
VivekuniQ wrote: what's going to be your gift for her this xmas???
i doubt that she looks at CodeProject (actually, she hate it ) but i cannot take the risk to write it there before Christmas... sorry 
now, i hope you having a good time too...
Merry Christmas dear Vivek.
see you - On CP naturally...

HI,
i have a problem with this function...

Sleep(200);
}while(mouse[1]<=300);
LUI_CloseDevice(0);
Sleep(200);
FreeLibrary(hLUIseDLL);
}
the debugger says that t and time1 is being used without being defined, but...??????
when i set the configurationmode to "release", it runs, if the do while loop exits
another error appears.
please help me...
thanks

Your variable time1 is a pointer only. There are no bytes that it points to that you can then fill up with the sprintf call. Off the top of my head that is probably the same thing with variable t.

for time1 :
iiscodered wrote: char *time1;
sprintf(time1,"%d:%d:%d",t->wHour,t->wMinute,t->wSecond);
this is not correct.
you have to allocate the memory space to then be able to write there (with the sprintf() call...).
for example, add this :
<font color=blue>char</font>* time1 = <font color=blue>new char</font>[10];
<font color=green>
<font color=blue>delete</font>[] time1;
for t :
first of all, choose variable names that denote clearly what it is supposed to do !!! t is not an explicit name.
iiscodered wrote: LPSYSTEMTIME t;
GetLocalTime(t);
same this again here.
t is not allocated...
it seems to me that you are new to C++, aren't you ?
moreover, the compiler might have told you a clear enough message of what was going wrong in you code... read them with interrest, ,compiler is your friend !

you should use 'new' .
i.e: char *time = new char(10);

Just declare the 't' string to have soem data space available.
Do
char time1[32];
instead of
char *time1;
and it will be fine.

Hi,
Since I can't put the initialization of a static data member in the class definition, how can I assign the value of lets's say a document data member to an object's static data member ?
Thx.

You have to do it in the cpp file
class foo
{
static int x;
int doFoo();
};
int foo::x = 12;
int foo::doFoo()
{
...
}

Is static data member accesible
only accessible by scope resolution operator .
say
by "this" pointer .(or pointer to class)

that doesn't mean its accesible only by a "::", but since its accessed directly through a class we need to use ::. its not accessed thru an object.(.) if u do so by an object, it creates new values everytime new objects get instantiated but here ::, its static (same)for all.
