For Loop Does not End

[lakepeir]

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++)
{
SafeArrayPutElement(psaArray, &lVal, &j);

}

Thanks!

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.

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

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?

SafeArrayPutElement 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,rgsaBound);

psaArray = SafeArrayCreate(VT_VARIANT,2,rgsaBound);

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.
