Getting Duplicate Values in Hash
Gday, According to the perlfunc reference, "When used on a hash element, it tells you whether the value is defined, not whether the key exists in the hash. Use exists for the latter purpose." So your checking line should read: if (!exists($GlobalUserList{$UserID})) -
I despair! no where else to turn. CGI error
According to the perl pages, putting quotes around the first terminator will fix the problem. As in: print <<'END'; Regards, Pat -
Write STDERR into file
If you are running this program from a command line, try "progname 2> errlog.txt" or "progname > all-log.txt 2>&1" (And remove your STDERR close and reopen from your code). The first redirects only STDERR to a file, and the second redirects both STDOUT and STDERR. Hope this... -

<b>Date from and through and QuickReports</b>
Gday there, In my report classes, I generally create a "SetParams" method. In your case, I would create one as: void __fastcall TMyReport::SetParams(TDateTime fromdate, TDateTime todate) { // do something with dates DateLabel->Caption =...- pheuvel
