in my application I sometimes use KeyPress event. in the event handler I
have to check the char the user is trying to type.
in NTs everything is correct. however on W98 I've noticed that the character
given in
e.KeyChar (e is KeyPressEventArgs of course)
is NOT correctly converted ToString() when I type polish specific letters!
instead of the letter 'polish l' I get '3', instead of 'polish z' I get '?'

I am trying to trap on a keypress "+" event and convert it to a tab for a
high-speed dataentry form that is done entirely from a 10-key. However, I do
NOT want the "+" character to be passed on to the textbox.
I am using code similar to this:
public class FastEntryControl : TextBox
{
protected override void OnKeyPress(KeyPressEventArgs e)

Hi All,
In VB6, I had text boxes which, in I wanted to allow numeric data
only. To do this, I put some code in the KeyPress event of the
control, and if the key that was entered was outside the range of 0-9,
then I reset the KeyAscii prperty to 0. Thus:
Private Sub tTransactionAmount_KeyPress(KeyAscii As Integer)
If Keyascii < 48 Or Keyascii > 57 Then Keyascii = 0
End Sub

It is not that I don't appreciate all of your comments - and I'm definitely reading them all - but I think I have a differing opinion of how I want to handle the 'user experience' in the application I'm creating. While I know I could allow the user to enter in number and alpha text - in a text box - and then tell them when the execuate a command "This is not numeric data", I...

I am currently trying to figure my way how to output strings to a file.
I have seen all the many posts and such how to do it in a console program, and have had much success doing it that way. This is a gui app though. What I want to be able to do is take strings from a text box, output those strings to char arrays, and then output the char arrays to a text file. Here is what I have so far:

Are there any javascript codes there?
Answer: Yes
On the PageLoad event call InitialClientControsl as follows

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,...
