[dba-VB] ControlChars in C#

Shamil,

That is a VERY sneaky trick, especially when you make gibes at VB! LOL

Hi Gustav,

In C# project you can set the reference to Microsoft.VisualBasic
assembly, then write:


using Microsoft.VisualBasic;

....

        private void bindingNavigatorPositionItem_KeyPress(object
sender, KeyPressEventArgs e)
        {
if (e.KeyChar != ControlChars.Back) e.Handled = true }

BTW, unlike Visual Basic this "screwed" above code lines will be
compiled well if you'll copy & paste them: I mean while posting Visual
basic sample one have to be careful with line wraps etc.

C# rules! Visual Basic serves :)  (a kind of kidding...)

Thanks.

Hi all

I can't believe this:

enta
rgs(VS.71).aspx

In Visual Basic you have a nice class ControlChars where you, for
example, ControlChars.Back for the BackSpace character.
In C# you have to write ugly (char)8 or '\b' in stone age C++ style.

So I have to write all this code to avoid the beep after pressing Enter
in the small navigator position field of the record navigation toolbar
while still be able to edit the record number with both the Delete and
the BackSpace keys:

        private void bindingNavigatorPositionItem_KeyPress(object
sender, KeyPressEventArgs e)
        {
            char c = e.KeyChar;
            if (Char.IsControl(c))
            {
                if (c != (char)8) 
                {
                    e.Handled = true;
                }
            }
        }

What do you do? Live with the beep or run your own homebuilt
ControlChars?
