I am looking for a regular expression to validate input into a textbox.
I only want to allow valid alpha-numeric characters (no special
characters, such as ?, *, {} [] etc...).
An example would be much-appreciated!
Thanks! 3 5027
Read that carefully http://www.15seconds.com/issue/010301.htm
I hope it helps

Hi sianan,
You could handle the keypress event and just allow numeric values. You
might also want to allow the delete key. Something like this:
void textBox1_KeyPre ss(object sender,
System.Windows. Forms.KeyPressE ventArgs e)
{
const char Delete = (char)8;
e.Handled = !char.IsDigit(e .KeyChar) && e.KeyChar != Delete;
}
Hope that helps,
John

I'm hopeless at regular expressions (I just don't use them often

Some document processing program I write has to deal with documents
that have headers and footers that are unnecessary for the main

each document, find out if it contains a header and/or a footer and

The headers and the footers have no specific format and I have to
detect and remove them using a list of strings that may appear as...

Hi,
I am replaceing a big string using different regular expressions (see
some example at the end of the message). The problem is whenever I
apply a "replace" it makes a new copy of string and I want to avoid
that. My question here is if there is a way to pass either a memory
stream or array of "find", "replace" expressions or any other way to
avoid multiple copies of a string.
Any help will be highly appreciated

I'm using regular expressions to extract some data and some links from some
web pages. I download the page and then I want to get a list of certain
links.
For building regular expressions, I use an app call The Regulator, which
makes it pretty easy to build and test regular expressions.
As a warning, I'm real weak with regular expressions. Let's say my regular
expression is:

I have a regular expression (^(.+)(?=\s*).*\1 ) that results in
matches. I would like to get what the actual regular expression is.
In other words, when I apply ^(.+)(?=\s*).*\1 to " HEART (CONDUCTION
DEFECT) 37.33/2 HEART (CONDUCTION DEFECT) WITH
CATHETER 37.34/2 " the expression is "HEART (CONDUCTION DEFECT)". How
do I gain access to the expression (not the matches) at runtime?
Thanks,
Mike

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.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
