Hello,
I need help with my for loop. The loop does not end. It should end
when i is one less than uBound. What happens is that when i is 1 less
than uBound, the loop continues with a weird value 5432325 (I have no
idea how this value is generated, uBound is less than 10.) and then i
is equal to zero again. Here's the code:
for (int i=0; i < uBound; i++)
for (int j=0; j < uBound2; j++)
{
SafeArrayPutEle ment(psaArray, &lVal, &j);
}
Thanks! 7 1966 la******@yahoo. com wrote: Hello,

Your problem is not in this code.
Find out what changes i. Many debuggers have "watch points" which break
when the value of a location in memory changes. la******@yahoo. com wrote: Hello,

You are sending the address of "j" in the function
"SafeArrayPutEl ements". Are you modifying the value of "j" there ?
It would be safer to declare "j" as a "const" parameter in function
"SafeArrayPutEl ements".

You are obviously leaving something out from the code you posted; how do
you know what the value of i is? I don't see any print statements. Could
you post a more complete code snippet? la******@yahoo. com wrote: Hello,

SafeArrayPutEle ment must be doing something smelly on the stack, post
its code.
I'd look for an array that's one too small.

i++ increments the i value as it goes through the loop. The code
before it just initializes values such as the array, etc.
Code:
long lVal=0;
SafeArray psaArray;
SAFEARRAYBOUND rgsaBound[2];
rgsaBound[0].cElements = 4;
rgsaBound[0].lLbound = 0;
rgsaBound[1].cElements = 3;
rgsaBound[1].lLbound = 0;
psaArray = SafeArrayCreate (VT_VARIANT,2,r gsaBound); la******@yahoo. com wrote: i++ increments the i value as it goes through the loop. The code before it just initializes values such as the array, etc.

So?
SafeArray is not a standard C++ type. Neither is SAFEARRAYBOUND.
SafeArrayCreate is not a standard function. Perhaps you should
ask in a newsgroup where they are on topic...

You clearly have a bug in your program. You clearly haven't posted the
part of the code that has the bug yet. Keep trying.

Take some standard code such as shown below. It simply loops to add up a
series of terms and it produces the correct result.
// sum numbers with a loop
public int DoSumLooping(int iterations)
{
int result = 0;
for(int i = 1;i <=iterations;i++)

result += i;

What I try to do is to iterate over two variables using template
metaprogramming. I've specialized it such that when it reaches the end
of a row ot starts on the next and when it reaches the last row it stops..
At least that's what I thought I did, but VC71 says "warning C4717:
'LOOP<0,1>::DO' : recursive on all control paths, function will cause
runtime stack overflow".
What's wrong?
Here's the code:

Hi
From what I have understood from various posts in this newsgroup, writing event
loops pretty much comes down to this:
while (true) {
handleEvents();
sleep(1); // or _sleep() or nanosleep(), depending on platform

I'm working on a function which creates a pointers to an array of unsigned
ints based off a number read from a file. I then continue to read file names
from the file, convert the name to a char* and use it to load an texture
from some outside functions. My problem lies in the "for loop", the Code
goes as follows.
//I create the array of pointers, I'm using 2 just for the sake of an

Sometimes it is known in advance, that the time spent in a loop will be
in order of minutes or even hours, so it makes sense to optimize each
element in the loop to make it run faster.
One of instructions which can sure be optimized away is the check for
the break condition, at least within the time where it is known that the
loop will not reach it.
Any idea how to write such a loop?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
