Hi,
i would like to cut the 1st '0'
You can try CString::TrimLe ft
e.g. CString str = _T ("090");
str = str.Trimeft (_T ('0'));
Note: it will not erase only the first '0', it will trim all leading '0's.
e.g. CString str = _T ("00090");
>i want to check whether it has a space there and return an error message. e.g. '0 9 0', then it will return an error
try CString::Find
e.g. CString str = _T ("0 9 0");
//trim leading '0'
str = str.Trimeft (_T ('0'));
//Search space
if( str.Find (_T (' ')) != -1 )
{
//found space, do what you want
}
Yours,
Michael

Sounds like you want to normalize a integer's string representation. Try
using Integer.TryPars e to find out if it's a valid number (will catch spaces
or any other non-digit characters), and then ToString on the result to
format it the way you like, with/without leading zeros, etc.

Hey all,
I've provided a form for a client of the company I work for that
basically emails the form data to an email address. Only a couple of
the many fields are required...nothing too fancy.
However, the sys admin has made the following request:
"All fields, not just the required fields, need validation for syntax,
shell escape characters and string length. This is a security issue."

Hi,
I have 6 If Then Else statements I was supposed to write. I did so but I
know that they have to be wrong because they all look the same. Could
someone take a look at them and point me in the right direction about what I
am not doing correctly?
1.. Write an If Then Else statement that displays the string "Pontiac" in
the CarMakeLabel control if the CarTextBox control contains the string
"Grand Am" (in any case).

I've seen a few people asking for this elsewhere, so here's a basic
implementation of a string trie in C#. I'm using this to load and
search a dictionary of about two hundred thousand words. It's fairly
quick (a couple of seconds for the full load). It's a bit of a memory
hog -- about 50MB resident, once the file is loaded -- but most of my
C#/.NET programs are.
Example usage:
StringTrie st = new StringTrie();

I found a stored procedure online a while back and want to inplement it. The only problem is that it doesn't check to see if the number generated is currently in use in the DB.
I know it's really unlikely for the same number to be generated twice (with a 10 digit number) but it's for a shopping cart so I need it to be 100% reliable.
I thought about opening a cursor then looping through each distinct record in the DB but couldn't figure...

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.
