hello
what's the diff between lock(Employees.SyncRoot) and lock(Employees)?
(Employees can be any ICollection, ArrayList, Hashtable what not .. don't matter)
Thanks

The SyncRoot property is used when you create synchronized collections using the .Synchronized() method. All operations on the synchronized collection lock on the object returned by the SyncRoot property. Creating synchronized collections using Synchronized() is not recommended though, because just making individual operations threadsafe usually isn't enough.
Other than that, it doesn't really matter.

Hi there,
What kind of error you are getting ?! if no exception then did you make sure that the source datatable has data? and is the connection string correct to be for the destination database ?!

Hi,
I need to write a program that sendes some keystrokes, strings and other values to another application.
I look for an article/tutorial for that goal.

Here is an article for sending keystokes: [^]

I have 2 more questions:
1. I think I will have to use the spy++ tool. Where can I find the ttol and a tutorial of for it?
2. Is it possible to send keystorkes to websites?

|
Use a webbrowser control and load the webpage inside it.
Thanks,

Hi Guys
Here's the description of the licensing component I've created: -
1. I created a pair of asymmetric keys using RSA algorithm. I embeded the "public key" into the code and kept the "private key" securely with me.
2. Now, when a user tries to run the program, the program looks into registry for a valid license string. If not found, it does the following: -
a. It pulls out a string comprising of the MAC-ID and CPU-ID and hashes it using MD5 algorithms.
b. The above hash is sent back to me by the user.
c. I sign this hash using my private key, and add the start-date and end-date for the license period, and create a license string for the user. This I send back to the user and he enters this into the program.
d. The program, now verifies the signature of this license using the public key. If successful, it matches the MAC-ID and CPU-ID to make sure that the license is intended for this very computer hardware. it then saves this license key into registry to perform the license validation everytime the program is run.
It all works fine, except the following - Let's say I've provided the license for the period between 01 Jan 2009 to 31 Dec 2009. The license is valid as long as the local date on computer of the user is within this range. This means the user can change the date and keep running the program even if the license period expires. I know this is a standard problem, and I also hope this must have been solved. All I'm looking forward is to fix this.
Pls suggest.

Hi!
Either you contact an internet time server to find out the correct time or you save the last time your application was used somewhere on the user's computer (using a symmetric encryption) and compare the current (local) time to this value to find out whether tha local time has been modified.

As a legitimate user, that annoys the hell out of me. My internet connection gets very flaky when it rains (should be fixed in next few months tho) and being unable to use software I have paid for because of events outside my control is REALlY irritating, and I tend to go elsewaher at the first oportunity. If you are going to do something like this, let your users know (in large letters) before they pay for it.

The current date is so integral to most systems that I could not imagine anyone changing the clock back just to run some SW, maybe for for trial periods but not for any length of time.

Or on a dedicated system. Maybe even wipe it and reinstall periodically.

hello ! do any 1 know to how create even_click for dynamic button with C# ? if any1 know , please give me some guide line....
|
|
|
|
|
By "even_click", do you mean an event that fires on every other click of the button?
Click 1: Do something
Click 2: Ignore
Click 3: Do something
Click 4: Ignore
etc...
If this is Windows Forms, then I'd say keep a boolean flag in your form, and toggle it at the beginning of each button click. If your flag is true after the toggle, then continue with your event handler, otherwise return. While this may not be a true "even_click" click, it gives you the same effect. You would of course need a separate flag for each button that has such an event.
void button_Click(object sender, EventArgs e)
{
flag = !flag
if(!flag)
{
return;
}
}

The actual method itself you will have to create beforehand, you cannot do this dynamically (it can be done by dynamcaly generating IL I believe but it's probably not neccesary).
You should create a general method that all your dynamic buttons call, you can retrieve the button from the sender parameter. To identify which button it is, you can use the Tag property (or use your own button class derived from Button and add some unique property to save some boxing/unboxing) if needed.
Button dynamicButton0 = new Button();
dynamicButton0.Click += new EventHandler(Button_Click);
dynamicButton0.Location = new Point(12, 12);
dynamicButton0.Tag = 0;
Controls.Add(dynamicButton0);
Button dynamicButton1 = new Button();
dynamicButton1.Click += new EventHandler(Button_Click);
dynamicButton1.Location = new Point(12, 34);
dynamicButton1.Tag = 1;
Controls.Add(dynamicButton1)
void Button_Click(object sender, EventArgs e)
{
Button clickedButton = sender as Button;
if (clickedButton.Tag is int)
{
int ID = (int)clickedButton.Tag;
MessageBox.Show(ID.ToString());
}
}
