i think that sample code is irrelevant, im just concerned if its theoretically possible
that two threads enter lock (obj) at the same time;
even if it isnt with single cpu, what about multi proc machine

If used properly, lock ensures one thread access the block. It won't make any difference in a multi processor machine, I guess.

explain structure with array in c#.net?
|
|
|

What do you need explained ? You can just create an array, but I'd use a list. You can create an array or a list of structs, same as you would any type.

You need to set up your website for this, on the server. You don't do it with code.

It depends on the website provider. Consult with them, they might provide some API's which can be used for this.

why would you want to do that?
panels go on forms, i dont think that forms can go in panels. if you want forms within forms you can google MDI windows

Hi,
have a look at Form.TopLevel
|
|
|
|
|
|
you can add parameters in the forms constructor or/and add a 2nd constructor with the parameters

Your Form should always have default constructor (with no params), else the VS designer will break.

Hi,
I've build an application but it isn't suppose to startup more than once.
How do I prevent my application to startup more than once??

Possibly the easiest way is to use a mutex. I posted a WPF version here[^], but it's easy enough to apply this to a Forms app.

There are countless articles on CodeProject providing solutions to your problem.
|
|
|
|
|
Hi,
actually none of those "solutions" do what the OP asks. At best they make the second
instance die rapidly, but they don't prevent it from starting up.
|
|
|
|
|
From what I have seen, most are the same, and I use the same thing in my applications too:
1. Create Mutex.
2. Check Mutex, then use IPC (with Remoting) to talk and do what you need with either instance.
|
|
|
|
|
In my code I am going to hide my active form and show another form. In that case are there any way to check me that other(2nd) form is loaded or not, Something like to check null or not.
Because currently I am facing for a problem that is sometime my form going crashed and nothing display, at the same time my other form is already hide. Then my application is something like losen(hang). I j’t want a solution for that.

your best fix is to fix the code in this form.
Also, a good solution is to have both forms as controls and show them on the one form.

In the code in the first form that displays the second form, after declaring the second form's instance but before calling show() subscribe to the second form's Shown event. Then, in the handler, hide the first form.
Form2 f2 = new Form2();
f2.Shown += new EventHandler(f2_Shown);
f2.Show();
void f2_Shown(object sender, EventArgs e)
{
Hide();
}

does someone know this code??
Record 9 of 10
this ^ is output on a label..
counting all the record on the database then displaying it like that..

hello.... is not a valid subject, it doesn't help us to work out if we can help, which is the purpose of a subject.
How are you displaying these records, in a grid, or otherwise ? If you have a dataset, then you can get a total from the Count of the rows in it.
