Losing Focus

Members,

I am interested in maintaining my tab order on a web page. I have a very simple page with 2 dialog boxes & 2 dropdownlist boxes.

Field1 DropDownList1
Field2 DropDownList2

I have the tab order set from left to right from the top down. So, you cursor move from Field1 to DropDownList1, to Field2 and finally to DropDownList2.

However, when the selectedindexchanged event fires, I no longer maintain my focus and leave DropDownList1 and land in Field2.

Where does the cursor go (besides the address bar of the current webpage) and how to I get the focus to move to the next field in order?

Any thoughts would be appreciated.

Thank you.

Strange IL code from simple C# expression

Hello, guys

I found an interesting topic on MS newsgroup. And I'd like to ask you a simple question. What is the value of "i" variable after the code ?

int i = 5;
i = i++;

???

Provide me, please, with an answer you though/expected just after you looked at the code. And then, any ideas why does C# compiler work so ? (if you will run the code, you will understand what I mean).

With best regards,
Andrew

The value of i will be 5 because the i++ increments the value AFTER the assignment.

If you want i to be 6 then you can do it like this:

<br />
int i = 5;<br />
i = ++i;<br />

The method above increments the value BEFORE the assignment.

By the way, this is not just a C# thing, any C syntax language shoould behave this way (incl. java, javascript, C++ etc..)

Yes, maybe other languages also should, but C++ produces 6. (managed and unmanaged versions).

I guess "5"

It's actually the same with C(++), because the expression i++ is evaluated AFTER the statement.

Not the same. I've checked on my VS 2003.

Problem is there in your example. Try to use different variable to distingush the difference.

int i=5,j=0;<br />
j=i++;

I know that my example is useless. It was interesting another thing: C(++) gives 6, but C# gives 5.

Never mind, the C# behavior is good described in MSDN[^].

IMO this is a compiler bug. From the IL you can see there is some funniness.

Easy, 5. The value of i is incremented after the expression is evaluated.

In this example:

Andrew Kirillov wrote:
int i = 5;
i = ++i;

Here, i will be 6. The value of i is incremented before the expression is evaluated.

This is all defined functionality in the C# language specification. C and C++ do the same thing.

No ! I wrote it alredy. I've tested it with VS.NET 2003. C++ (managed and unmanaged) gives 6.

Then I'd say the problem is with C++ not with C#.

Try this:

<br />
	int i = 5;<br />
	if (i++ == 5)<br />
	{<br />
		Console::WriteLine("Five");<br />
	}<br />
	else<br />
	{<br />
		Console::WriteLine("Six");<br />
	}<br />

In C# and C++ you should get "Five" as a result.

Yes, I know. It will be the same in both languages. I was interested in original code I wrote.

Actually you are right, it should be 6 (in your original code) in both C++ and C#. Nasty trick question that. So it would appear to be a problem with the C# compiler.

After doing some digging, the evaluation rules are slightly different between the C++ language specifications and the C# specs. It's not a bug as far the specifications describes the process.
