I have a button click event that takes information from controls and enters it into a table via INSERT INTO SQL statement in VBA.
I was wondering if there is anything I could add to this, or some other method to acquire the record number that is created for the record?
Could I just turn around and SELECT against the table and use rs.last?

I'm working with a time sensitive desktop application that uses p/invoke extensively, and I want to make sure that the code is not wasting a lot of time on CAS stackwalks.
I have used the SuppressUnmanagedCodeSecurity attribute where I think it is necessary, but I might have missed a few places. Does anyone know if there is a way to monitor the number of CAS stackwalks that are occurring, and better yet pinpoint the source of the security demands?

I'm trying to secure my rails 3 app against brute force login guessing. I'm using authlogic. What's the best way to force a user (or bot) to fill out a captcha after a specific number of failed login attempts? Does authlogic have a built in mechanism for recording how many consecutive failed attempts came from the same ip? I'd appreciate any help.
The documentation states: "Precision can range from 1 to 38. Scale can range from -84 to 127".
How can the scale be larger than the precision? For example I can't create a column with the datatype NUMBER(10, 100). Shouldn't the Scale range from -38 to 38?

In gawk I know two ways to test if a string contains a number. Which is best?
Method one: using regular expressions:
function method1(x) {
return x ~ /^[+-]?([0-9]+[.]?[0-9]*|[.][0-9]+)([eE][+-]?[0-9]+)?$/
}
Method two: the coercion trick (simpler):
function method2(x) {
return (x != "") && (x+0 == x)
}
Is there any reason to favor the more complex method1 over the simpler method2?
I'm sure this must be possible:
I want to have the revision number (from Subversion) put into a property that is accessible from Ant when my build runs in Luntbuild. There must be an OGNL expression that I can add to the Build Properties box on the configuration page for my Ant builder.

Therefore if one a user (staff or external) has an item out of inventory then no other users can get a hold of that item. Thanks, Any Ideas would be most appreciated!
Let's say I have this query:

Does the speed of this query depend on the number of rows that are present in table1?
Hello guys,
For a school project, we'll have to implement a ranking system. However, we figured that a dumb rank average would suck: something that one user ranked 5 stars would have a better average that something 188 users ranked 4 stars, and that's just stupid.
So I'm wondering if any of you have an example algorithm of "smart" ranking. It only needs to take in account the rankings given and the number of rankings.
Thanks!
I have a django model with a DateTimeField.
class Point(models.Model):
somedata = models.CharField(max_length=256)
time = models.DateTimeField()
I want to get a count of the number of these objects for each day. I can do this with the following SQL query, but don't know how to do it through django.
SELECT DATE(`time`), Count(*)
FROM `app_point`
GROUP BY DATE(`time`)
Being able to restrict the results to a date range would also be good.
I am writing a small C application that use some threads for processing data. I want to be able to know the number of processors on a certain machine, without using system() & in combination to a small script.
The only way i can think of is to parse /proc/cpuinfo. Any other useful suggestions ?
