A89: installing C Event Hooks + misc other...


Hi guys!

I've got a small program here that i have been running as a resident prog on
my calc that hooks into the events.... I've been banging my head against the
wall trying to find a way to make an installer/deinstaller for it! The hook
function itself calls several other functions making it a little tougher. I
can't do it like a regular tsr because of course the event hook function
takes parameters! HELP!

Now on to the misc other...
How does one include special characters in an array?
say i have an array like this

char * El[]={
"Element0",
"Element1",
"Elementx"
};

1. if I wanted to include say a left arrow character (conversion arrow) in
an element how would i do that?
Example: "Elem->ent1"  where -> stands for the conversion arrow of course...


2. My event hook needs only to watch for keypresses when the calc is on the
home screen... I can prevent it from processing the key presses on nearly
every thing except for when the Catalog is displayed, how would i fix this?
Right now my code looks like this:

   if((FirstWindow->TaskId==EV_getAppID("TIHOME")) &&
((FirstWindow->Flags&WF_ACTIVE)==WF_ACTIVE))
{then do stuff here because the home screen is active}

That code checks to see if the FirstWindow's TaskId is that of the Home
Screen app and it checks to see if the WF_ACTIVE flag is set...

although I've tried many many other forms, this seems to work the best...
when it comes right down to it, I only need to process CM_KEYPRESS events
when the user is in the *home screen* text editor... I do have code that
finds the TEXT_EDIT structure for the home screen which contains a pointer
to the "parent" window...
Just so I don't confuse anyone, the Home Screen Text Editor is that little
bar on the bottom where you type calculations; not the normal text editor...

oh yea, one more thing
would someone explain why this function gives a warning when compiled

//isLike(StrToTestForMatch,StrToMatch)
//all characters in s1 must = len(s1) chars in string s2
//returns strlen(s2) or 0 (NULL) if no match

unsigned long isLike(const char* s1, const char* s2)
{
 unsigned long x=0;

 while(s1[x]==s2[x])
  x++;

 return x==strlen(s2)?x:0;        //the warning comes from the strlen
function:
                                                    //discards qualifiers
from pointer target type
                                                    // which would be s2...
}

any optimizations for speed would be welcome as well This function needs to
be fast...

and that's my monthly brain scandisk/defrag...
Thanks,

Greg
