As a minor semantic difference - the & operator in C# is a bitwise and, whereas && is the logical and which also shortcircuits. (Like C++)
I'm used to using & with caution - coming from a C++ background - you could have two "true" results from a function - but 1 & 2 == false  In C# this cautioning really doesnt apply though.

There is no semantic difference.
The following are *exactly* equivalent:
VB: C#:
And &
Or |
AndAlso &&
OrElse ||
The VB 'And' is *both* a bitwise operator and a non-short-circuiting logical operator, as is the C# '&' operator. Ditto for 'Or' and '|'.
They produce identical results when used in the same situations.
Obviously, it usually makes sense to use 'AndAlso' and 'OrElse' in most logical evaluation situations, but occasionally 'And' and 'Or' may be preferred, in exactly the same cases where '&' and '|' may be preferred in C#.

Hi All!
I Am Using Visual Studio 2005 .NET Standard Edition and I have run into (Yet Another)
HUGE Problem.
My MenuStrip Isn't Working.
It's inside a tabcontrol near the bottom of my form and isn't my forms main MenuStrip, when my
app starts, as if by magic, all menustripitems on the control dissappear! Leaving an empty menustrip!
It's really been bugging me, i've tried refreshing it, toggline it's visibility and everything.
nothing Seems to work.
Any Help Would really be appreiciated!

Hey Everybody I Solved it! 
The Bug itself seems to be extremely difficult, if not impossible to fix BUT by simply docking the
toolstripcontainer and menustrip inside a panel everything works fine!
It seems that the tabcontrol and the toolstripcontainer and/or menustrip don't mix well, but hey,
the panel method works, and works well!
Thanks!

Thanks.

First off, you should not have anything in a tabcontrol except for tabpages. If the menu is in a tabpage then their shouldn't be any problem.

read the sticky at the top of the forum 'need help' is not a valid subject, everyone who posts, needs help.
If you write good print code, it won't overlap. Hard to say more without seeing code.

You could try to write a custom control to do that. Good luck, it won't be trivial.

Doesn't this create an array with 10 strings ? what if there's more than 10 chars in the string ? why create an array of strings and not chars ? This is very bad code.
I also don't see how it helps, he didn't ask to flip the string, but for it to show backwards, in general use, I assumed.

Try this code
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
TextBox1.Text = e.KeyChar & sender.text
e.KeyChar = Nothing
End Sub
some more validations has to be add as per your requirement.

yeah, this is a start. The cases to watch are, where is the cursor ? What happens if the user uses the arrows ? What if they press delete ?

@ Christian Graus
If u observe my answer,
very first line i wrote
" Try this code" : that means am not giving conformation it will 100% works. and am not giving 100% Solution. am just giving a suggestion.
and last line i wrote,
" some more validations has to be added......"
that mean Programs has to add his default validations like u wrote
"The cases to watch are, where is the cursor ? What happens if the user uses the arrows ? What if they press delete ? "
====================================
here is the code
If Char.IsLetterOrDigit(e.KeyChar) Then
TextBox1.Text = e.KeyChar & sender.text
e.KeyChar = Nothing
End If
Thanks

Yes, I saw what you said, I was not contradicting you. I was more adding to it, if he wants to build on your code, I was being more specific. You said 'some more validations...' and you were right. I was suggesting what some of those may need to be.

Hello
How i can change the color of the selected item in a listbox ?
Thanks in advance

Hi,
you can draw the listbox items yourself when you modify DrawMode and provide
a DrawItem handler. That way you are fully in charge of position, size, color, whatever.

Hi!
I Need to check javascript in a richtextbox for errors at the click of a button,
I know that this is no small task, and every attempt I can think of or have tried
just loops through the textbox, highlighting and checking each and every word
and repeating this time and time again for every single function or method used.
It is Ridiculously Slow.
Is there an engine or perhaps some code out there that will allow me to do this reasonably
Quickly?
Thanks!
MrWolfy

Hi,
I would suggest you forget about the RTB and check the JavaScript in memory;
only touch the RTB (if you must) when there is something to report.
|
|
|
|
|
Thanks!
That helps a lot, but i still can't seem to figure out just how to check the javascript for
errors accurately, any advice?
Thanks Again!

it all depends on how far you want to take this. Maybe Google[^] will help you?

Hello
How can i put the data of my dataset into my multiline textboxe
please help
Thanks in advance
Assaf

Loop through each row of the dataset, add it to a StringBuilder and then set the Text property on the textbox to the ToString() output of the StringBuilder.
Why wouldn't you just display the dataset in a datagrid?
