Where is oScope used?

some inside SaveCoreOperation and hint, death came after many iterations

But you never passed oScope to this method. It takes the only parameter which is oShop

why'd you need to, scope wraps code whether inline or not between "using" open and close bracket.
using (oScope = new TransactionScope(TransactionScopeOption.Required, TimeSpan.FromMilliseconds(0)))<br />
{<br />
nGeneratedId = SaveCoreOperations(oShop);
oScope.Complete();<br />
}
I am suspecting perhaps from within "SaveCoreOperations" oConn used was opened/closed then "Re-opened"... not sure

You can get this error message if your Distributed Transaction Coordinator service is not running. Use Administrative Tools to check the Status of the service has Started and that the Startup Type is Automatic.
Also, the default timeout/timespan is 1 minute and the default machine config caps it to 10 minutes.

Hi
Im placing some controls dynamically on tool strip control and i'm handling that controls click event as well tool strips click event. But when ever i click the control it triggers both the event.
I want to cancel tool strips event when i click the control.. how can i do this?
|
|
|
|

Do you need the toolstrip's Click event to be handled at all (I've never found a need for it personally as all I'm ever interested in is the items, not the strip)?

Well, I'm handling tool strip click event also with different context.
|
|
|
|
|

What is it that you are using the ToolStrip's click event for?

Have a look at this[^]
The example is in VB.Net but I hope you can easily convert it to C#.

form name is "Test".
i want to close this form using short cut Alt+F4
cany anyone help me
|
|
|
|
|
Normally this should work by default...
|
|
|
|
|
Just press Alt+F4 in your keyboard. The form will be closed automatically.
You don't need to write some codes for that.
|
|
|
|
|
It should just work as others have said. If for some reason it doesn't, you can code it yourself. This is a little function I use occaisionally to do the opposite - stop Alt+F4 closing the form. Adapt it to suit.
private const int WM_SYSKEYDOWN = 0x0104;
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
return ((msg.Msg == WM_SYSKEYDOWN) && (keyData == (Keys.Alt | Keys.F4)));
}

try
{
int i = 1;
int j = 2;
return i;
}
finally
{
i += 3;
}
The code in the finally statement will be executed ? when? before return or after return ?
|
|
|
|
|
What happened when you tried?
|
|

Well, that's a dumb question. If there's no other code, then before or after the return are basically the same thing, excepting that when the code returns, i will no longer exist. In fact, I don't think this will compile, because the scope of i is the try block, I think you need to define it outside the try for the catch to see it.

Well that is a dumb answer because it's totally unhelpful!
You're right that it won't compile, but surely you can see that the question works by simply declaring i at the method level instead. And there is in fact a subtle effect of the try-finally.
int foo()
{
int i = 1;
try { return i; }
finally { i = 5; }
}
This code compiles, but what does foo() return? I think quite a lot of people would expect it to return 5, since the finally block is executed before the method returns. But the return value is *evaluated* before the finally block runs and the method returns 1.
Now what would happen if we boxed the int in a class of our own?
class BoxedInt { public int Value; }
BoxedInt bar()
{
BoxedInt i = new BoxedInt() { Value = 1 };
try { return i; }
finally { i.Value = 5; }
}
While foo() returns 1, bar() returns a BoxedInt whose Value is 5. That's because BoxedInt is a class and thus a reference type, so it does not matter if the return value is evaluated before or after the finally block executes. Change BoxedInt to a struct, and bar will return a BoxedInt with Value equal to 1 as well.
I'd say there's some subtlety here, so calling that a stupid question seems to me rather a stretch.

So... you did try it, but asked the question anyway?
|
|

Now that got me nicely confused.
You replied to my message so presumably "you" means me. But what "it" and "the question" refers to is less clear. I tried many things including compiling and running the various code snippets I've put up on this thread. I may have asked questions too, but I am not the OP so if you were referring to the original message that might explain the confusion.
If you did mean I tried something (and consequently found out what it does) and still asked what it does, let me know what it was and I will attempt to communicate whatever it was I was wondering about more clearly.

|

Whoops, I meant to reply to the OP.
|
|

I think it was an interesting question... thou I don't see why you need to ask when you can just try yourself. Thou as Christian said, you variable in the finally block is not in scope.
The answer would appear that the finally code is executed after the return thou I would say that the function is not complete until after the finally block. That means whenever return is called then that is the value that will be return regardless of what is done in the finally block.
I wonder what would happen if you put a return in the finally block too....
...oh, you cant return from a finally block.

The answer is in fact more subtle: The finally block executes before the method returns, but the return value is *evaluated* before the finally block runs. Because his code works with a value type (int) the increment he did in the finally is not reflected in the return value of the method - it's as if the compiler transformed return i; to int ret = i; i += 3; return ret;, executing the finally block after evaluating the return expression, but before returning. If it had been an object (reference type) and the finally modified the state of that object, the caller would "see" the changes made by the finally block. See my replies above if you want more details.
