In MS Access, I want to restrict entry of text into a field. I've provided limits via a dropdown listbox I created. So I only want any one of those values as possibilities to fill that field for any new records created. The problem is that currently I can enter any text I want by simply ignoring the drop down text values I've populated in the list box. Can I lock the field so only those drop down text values I've created can be selected? If so, how please? Thank you!

Need help understanding a part of a program which is able to find the GCD. can someone explaine the part from int gcd to before int main starts.

#include
using namespace std;

int gcd (int value1, int value2)
{ int r;
while (value2!=0)
{ r = value1% value2;
value1 = value2;
value2 = r; }
return value1; }
int main (int x, int y, int howmany)
{
cout << "\n Finding the GCD in a C++ program";
cout <<"\n Enter how many GCD computations? ";
cin >> howmany;
for (int i = 0; i < howmany; ++i)
{ cout << "\n Enter two integers: ";
cin >> x >> y; // input of teh 2 values
cout << "\n GCD ("<< x << "," << y << ")=" <
}
}

I need to monitor a log file for a while and was going to have inittab run tail -f logfile | grep ERROR | xargs -n1 -i mailit.sh {}

Where mailit.sh is just a 2 line program:
echo $1 > error.log
mail -s "Error occured" my@email.com < error.log

or any other suggestions for realtime monitoring of a log file.
Its VERY BUSY always getting written too.

Thanks,

for i = 0 until a.length - 2
for j = i + 1 until a.length-1
if a[j] < a[i]
make a[i] = a[j] and make a[j] = a[i]

j = j+1

end for j

My homework asks "What is the output of the following?" and i'm thinking something is horribly wrong with this code or they skipped this in class.

the only thing vaguely tickling my brain is the true/false (1 or 0) thing. but if that's so, i didn't realize you could assign 1 or 0 to integers using true / false tests.

int main()
{
int a = 3, b = -1, c = 0, i, j, k, n;
i = a || b || c;
j = a && b && c;
k = a || b && c;
n = a && !(b || c);
printf("\ni = %d, j = %d, k = $d, n = %d\n", i, j, k, n);
}

I'm having trouble with the equations needed. we have learned the loops so far and i think this problem wants me to use the loops, and it looks like i need if-else as well. Here is the problem.

Write a program that asks the user to supply three positive integers k, m and n, with k being greater than 1. the program should compute the sum of all the integers between m and n that are divisible by k.

I don't know how to tell C that that i only want an integer evenly divisible by another. and then, i'm not quite sure how to get the addition of those integers done.

To answer this question you must know what Pivot is-the stick figure animator.

On YouTube there are numerous Pivot animations with sound behind them-how is it done-if there are more than one give me them all (well, all that you can be bothered to do ;-))and I'll chose the easiest for me personally based on time, effort and programs I have.

cheers

Algorithm:
----------


start = 0
end = a.length -1

while start <= end

if (end-start) is multipliable by 2?
index = start + (end-start)/2
else
index = start +(end-start+1)/2


if a[index]>n
end = index-1
else if(a[index] start = indice + 1
else
return indice

end while
