typedef struct Applet
{
STRING * Name;
STRING * Author;
STRING * Version;
STRING * Description;
PANEL * Container;
void * Initilize;
void * Deinitlize;
int init;
}Applet;
if(is(applet->Container,SHOW) { reset(applet->Container,SHOW); return 0; }
Here I get a syntax error when I try to access a PANEL from the structure. Whats the bug there?? Thank && Regards

I'm not sure if this is the problem but try the struct-name APPLET in stead of Applet. Kartoffel

did you try what I suggested? I meant you use:
typedef struct
{
[...]
} APPLET;
and
APPLET* applet = sys_malloc(...);
Also make sure the pointers inside your struct are set to an object (PANEL* container to an existing PANEL*) or to an allocated memory block.

Try defining it without the *. I've got a pretty similar problem a couple of minutes ago. I wanted to add extra functionality to the panel's and made an "advanced panels" struct. looks like this:
typedef struct
{
PANEL* panel; // pointer to a standard panel
int anim; // Animation-Attribute for the panel
} advPANEL;
I defined it simply as:
advPANEL myAdvPanel;
myAdvPanel.panel = pan_create(NULL, 25);
if(myAdvPanel.panel != NULL)
{
myAdvPanel.panel.bmap = bmap_create("...");
myAdvPanel.panel.pos_x = ...
...
}
works like a charm. Cheers Roxas

Ugh, seriously, guys if you have no idea what you are saying then don't say anything at all. Lite-C is confusing enough for beginners especially when it comes to pointers. We don't need anymore false information the like of "void is faster than function because herp derp".
@Kartoffel: The case doesn't matter. If you are not sure about an answer, test it yourself first.
@Roxas: What you are describing is static vs dynamic memory allocation, however, even if Yashas hadn't allocated backing memory for his instance (which he has, as his second post shows), it wouldn't result in a compile time error.
