If anyone has a simple routine to validate that text
entered in a text box control contains only numbers (zip
code) or only alpha characters (name), can you please send
me? I'm new to this, and am not looking in the right
places to find answers.
Thanks!

I am experiencing some strange behavior between a UserControl's validating event and a treeview control. Initially, I thought it was related to an issue in the Knowledgebase article 810852 (http://support.microsoft.com/kb/810852), but then I realized that the hotfix mentioned was in .Net v1.1, which I am using.
I took the sample from that article and recreated the situation I see in my application. (Code included below.)

Hello,
We have an ASP.NET 2.0 (C#) web form that contains a textbox for users to
enter multiple e-mail addresses separated by semicolons. We need to
validate that each individual e-mail address entered is a valid e-mail
address format. We've added a CustomValidator to perform this validation.
We have the server-side validation working fine, but now we need to add some
client-side validation via JavaScript. We are having difficulties...

Hi There,
I want to be able to validate data entered by a user onto a form.
Different fields will have different validation requirements.
As an example, a text box may only allow numeric, alpha or alpha numeric
entry and/or may have limitations on length or value.
I thought about inheriting a control from one of the standard forms controls

I need some help with validating user input. I am writing a C computer
program for an intro to C course. Here is the situation. I am
creating an application that will do currency conversions. The user
will be presented with a list of 5 selections they can make. They will
then be prompted for which selection they want to enter (which can only
be 1-5, no characters or anything like it). Once they select the

I have two text boxes. If (and only if) a user enters something in
textbox1, I need to validate that they also entered something in
Textbox2. IOW, I need to validate that they entered something in
textbox1...and if they did...validate that they entered something in
textbox2. Is there an easy way to do this, like with Validation
controls?
TIA for any help,

I'm working on examples of programming in several languages, all
(except PHP) running under CGI so that I can show both the source
files and the actually running of the examples online. The first
set of examples, after decoding the HTML FORM contents, merely
verifies the text within a field to make sure it is a valid
representation of an integer, without any junk thrown in, i.e. it
must satisfy the regular expression: ^ *?+ *$
If the...

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,...
