I couldt get the Suspend thing to work, but the AddRange() works perfect

OK, so I've recently picked up C#. Actually, I knew Jack about it until I dumped some VB code into it, ran some regexs, cleaned up the errors and have finally whittled it down to a total of 16 errors.
I fixed 12 of the "Object reference is required for the nonstatic field, method or property [blah]" but there's 4 left.
In VB it works great with: frmMain.pnlDisplay.Invalidate()
but to fix the CS0120, MSDN basically recommends replacing it with "new frmMain()".
Yeah, great, what that does is creates an infinite loop of new forms being created within one another. It hasn't overloaded any stacks yet but I do have heaps (bad pun) of memory.
Basically I'd like to know how I can access a control on a form from within another class, without having to create new instances and preferably without having to pass references to "this" around everywhere. Or can I get away with in the constructor only?

Make a method in the other class that accesses its own controls, then call the method from where ever you need to.

Would seem logical I suppose...
Thanks
Wish I'd stuck with VB. *thinks* Wish I knew how to work C# better.

Perhaps not.
Double post, yeah, but I've only just put the change in.
It now reads "Object reference required for nonstatic [...] 'frmMain.paintDisplay()'"

Are you trying to call this stuff from a static method? Because if so, that'll be the problem. You'd need to make the method not static, or make everything else inside the method static.
Or wait, if your using a static method, pass frmMain as a parameter, and then it should work:
static void myMethod(Form myForm) {
myForm.paintDisplay();
}
...
myMethod(frmMain)
and if your method isn't static, then im not sure. Keep at it though.

Hi,
I'm looking for a code sample in C# or java for bluetooth.
I want to make a simple application for the desktop to log all bluetooth devices that are nearby my bluetooth dongle.
I've been searching for 3 days. So far i can only find code samples for mobile phones.
Thanks in advance!

I have a if statement and a table with 2 atributes. They are description and date. I will check if there is in the table some date like 01-01-2008.
String test "01-01-2008";
if (test.Equals(here I will a SELECT query like SELECT date FROM appointmentTable))
{
textbox1.text = "The description on this date is: " + Here I will the descripton of the selected date
}
Does someone know how I can make something like this in C#?

You need to do the select statement first, then you can compare the data that comes out. You probably want them both to be date time objects, so you compare the dates and not their string representation.

There is a screen that appears before a user logs off.
He has to choose whether to log off or switch user.
Or it can be the screen of log off / shut down and etc.
I want to perform some code before this screen appears.
How can I register to the event ?
Thanks,
Clint

What happens when you try it?

are you kididng it must be some way to compile it like working with bits and bytes ore such ...

Why would I be kididng [sic]? You asked whether variables names that begin with a number are valid. I suggested that you tried it and observed what happened. You tried it and found that it didn't work. By following an empirical approach, you have answered your own question.

This sentence is nonsense. I have no idea what you are talking about.

You lose.
Not even with the @ identifier specifier does it work:
int @int = 1;
int @1name = 1;
An identifier in C# can never ever start with a digit.

Bonus question: can identifier start with digit in IL? (I gave up after maybe 2 min. of googling  )

I hope you didn't bet too much, or you could end up buying your teacher a Porsche. He's right, and you're wrong. Variables can't start with a number as you found out when you tried to compile it.
Deja View - the feeling that you've seen this post before.

but if i enum ??
enum(1a,2a,3a,4a,5a)

Enum members are not variables, and even those identifier cannot start with a number.
Had you tried it yourself, you would have found out quite easily.
But, in either case, you still lose...
