Hello again. To further that question, I keep getting
Bus error exception . . . (DmDetachRecord).
What does the Bus Error means??
Thanks again.

Subject: Help with DmDeleteRecord and DmDetachRecord.
Hello everyone.
I need some help with DmDetachRecord. Basically I am wondering what
happens
to the MemHandle that is returned if I do not use it (i.e. never
call
MemHandleLock on it)?? Will the OS eventually free that memory?
Furthermore, I am sure someone can help me very quickly. I have a
record
from a database. Now, I want to update a field in that record, what
is the
best way to do it?
Sample code would be much appreciated.
Thanks,

Subject: RE: Arrays and Pointers issue - HELP!!
To anyone that looks into this...pay special attention to my
arrays
(which
at least one is an array of pointers)...They are declared in
BuildReferences, and then I am trying to pass them by
reference to
alGetKey,
and then pass individual elements by value to alFindRecNum.
Thanks
for any
feed back you can give.

Subject: Arrays and Pointers issue - HELP!!
I am messing with some pointers and multidimensional arrays,
and I
belive I
am following K&R, but CodeWarrior is balking at me. Any
ideas what
my
problem is? Sample code is below...I have stripped out all
of the
code
except the declarations and the function definitions...
The errors I get keep saying:
Error : pointer/array required
Main.c line 973 matchRec = alFindRecNum(keyElems[k],
Values[j][k],
Sizes[j][k], RecNums[k]);
Error : cannot convert
'short * (*)[7]' to
'short **'
Main.c line 1242 pTbl, tmpRow, curElem,
keyElems);
//Sample Code
static Int alFindRecNum(ElementType *keyElem, IntPtr Values,
Int
Size, Int
startRec)
{
return 0;
}
static Boolean alGetKey(Int j, Int k, Int NumKeyElems,
IntPtr
Values[], Int
Sizes[],
Int RecNums[], TABLE_REC
*pTbl, WORD
tmpRow,
ElementType *curElem,
ElementType *keyElems[] )
{
Int matchRec;
matchRec = alFindRecNum(keyElems[k], Values[j][k],
Sizes[j][k],
RecNums[k]);
return alGetKey(j, k+1, NumKeyElems, Values, Sizes,
RecNums,
pTbl, tmpRow, curElem,
keyElems);
}
static Boolean BuildReferences()
{
ElementType *curElem;
ElementType *keyElems[7];
Int i,j,k,m,x;
WORD tmpRow, tblIndex;
TABLE_REC *pTbl;
Int numRecs;
UInt recordIndex;
ULong CurPosValues, CurPosStrings, CurPosOffsets;
ULong CurPosKeys[6];
Int ValuesSize, valColumn, descColumn;
IntPtr Keys[7][7], Values[7][7];
Int Sizes[7][7];
Int NumKeyElems;
Int RecNums[7];
Err err;
if (curElem->KeyElemNums[1] != 0)
alGetKey(j, k, NumKeyElems, Values, Sizes,
RecNums,
pTbl, tmpRow, curElem, keyElems);
return true;
}
