Luc,
I'd like to know where you've come into the need of nullable types in C# other working with than ADO.NET of course 
|

huh?
I just said I never got used to them since most of the time they have
not been available; we can live without, easily.
And I don't exactly like the extra code they generate nor the extra data memory
they cause either.

Oh I took it that you're not used to them yet because, well you are using them. My mistake then :/

There are 2. One is a conditional operation and the other is a Null-Coalescing operator.
1) Conditional
result = condition ? truepart : falsepart;
if(condition) result = truepart;
else result = falsepart;
2 Coalescing (evaluate b if a is null)
c = a ?? b
if(a == null) c = b;
else c = a;
*and the nullable type* Thanks Pete

What about setting a nullable variable? BTW - the conditional is called the ternary operator.

I guess that's what I get, I forgot to take my umm... what's it called... that stuff that makes you remember better? darn it.
Thanks for the correction.

Which BTW is quite a silly name, as it only means "three operand operator", and doesn't say anything at all what the operator does with the operands.
Despite everything, the person most likely to be fooling you next is yourself.

hy everyone!
i was wondering if there is a default string function to cut a string if it is to long to e.g. insert it into a textfield.
what i want to do:
i created a table which allows strings up to a maximum length. if it is too long i have to cut the rest.
lets say there is a string
"1,2,3,4,5,6,7,8,9,10" but the maximum length, which could be insert is 16 characters so the maximum string would be e.g. "1,2,3,4,5,6,7,8," but is there a chance to cut it to this length without having to parse it or without having to insert 16 characters one by one in a loop?
thanks.
stephan.

string s = "1,2,3,4,5,6,7,8,9,10";
string cut = s.Substring(0, 16);
so:
s = "1,2,3,4,5,6,7,8,9,10";
cut = "1,2,3,4,5,6,7,8,";
|

It would be best to check the length before trying to substring that... I don't think anyone likes argument out of range exceptions....
|
|
|
|

thanks for the hints. i guess the best solution will be
if (mystring.length > maximumlength)
{
mystring = mystring.Substring(0, maximumlength);
}
so if the string is already smaller than the maximum length, then it is easy to insert it, but if it is longer, then just the first characters (up to maximumlength) should be insert.
thanks again for the hints. i didn't know it was this easy

good morning from montreal,
i am working with a TURBO C 2.01 compiler -
with which i am still very satified - but i can't find anywhere a good
article how to incorperate ASSEMBLY language with this compiler. that's
really all for now. of course if someone could show me a SIMPLE code
fragment, from way back when, that's really all i,d like. So thanks
beforhand. allan.

you asked in the wrong forum.
this forum is about C#, a rather recent language, quite different from good old C.
I suggest you ask again in the C/C++ forum (unmanaged, no CLI), but even then don't
hold your breath...

It's been a really long time, but I think Borland used the following:
single line:
asm mov ah, 9
or a block:
asm
{
mov ax, 1234h
mov bx, ax
}
Hope that works. I think you can also link in your ASM files but that part of my brain has been overwritten.

I get an InvalidCastException in the bold part of the code (the "" and /object are not part of the code)
public void AthugaStafset()
{
SortedList SL = new SortedList();
SortedList SL2 = new SortedList();
SL.Add(0, "V1");
SL.Add(1, "V2");
SL.Add(2, "V3");
SL.Add(3, "V4");
SL.Add(4, "V5");
SL2.Add(0, richTextBox1.Text);
SL2.Add(1, richTextBox1.Text);
SL2.Add(2, richTextBox1.Text);
SL2.Add(3, richTextBox1.Text);
SL2.Add(4, richTextBox1.Text);
bool equal = Compare(SL, SL2);
if (equal)
{
richTextBox2.Text = "Right";
}
else
{
richTextBox2.Text = "They differ";
}
}
static bool Compare(SortedList SL, SortedList SL2)
{
if (SL.Count != SL2.Count)
{
return false;
}
foreach (KeyValuePair<object, string=""> item in SL)
{
if (!SL.Contains(item.Key))
{
// Return the moment we find a difference
return false;
}
}
// Must be the same
return true;
}

Change KeyValuePair<> to DictionaryEntry.
Remember to use the "code" and "pre" tags when posting code.

That worked, but now everything is equal or correct, even if I type in a wrong string.

I was waiting for you to get to that. You are comparing the Keys to both lists, not the Values. And the Keys in both lists are identical. Your compare function needs work.

Firstly, take more than a minute and consider the problem. Give it like ten.

Which I have.
This is the Compare code. I suspect it has something to do with the bold text. BUt I can´t put my finger on it.
static bool Compare(SortedList SL, SortedList SL2)
{
if (SL.Count != SL2.Count)
{
return false;
}
foreach (DictionaryEntry item in SL)
{
if (!SL.ContainsKey(item.Key))
{
return false;
}
}
return true;
}

Is this homework?
