This sounds like a homework problem. Even if someone here did it for you, you still wouldn't be able to do future (and harder!) problems.
Use an easy problem like this to develop your programming skills. Figure out the procedure you'd use to solve this with pen and paper. Then figure out how to implement this algorithm with C#.

Hi,
I have a textbox and i want to set focus to a particular row in the datagridview.

Is it possible to read a cookie that a website has created or write a cookie that the same website can use? I mean outside of the website itself? It's my own web site, by the way. I know the names and keys inside it and where it is stored already.
Thanks

Hey
I'm new to working with c# and am creating a desktop application which needs to store the source code of html files in a mssql database but i keep getting an error
Incorrect syntax near '<'.
Iv tried using SecurityElement.Escape(theSourceCode) but i get the same error only referencing a '&'
I'm hoping this will be an easy question for some one with a bit of exsperience in c# but is there a function to remove or encode the sql sensitive characters from the string containing the source code
Thanks in advance
Phil

So, show us your code and we can then see what you are doing wrong.

Yes. Use a parameterised query, then the value is escaped automatically.
Despite everything, the person most likely to be fooling you next is yourself.

"system.formatexception: datagridviewcomboboxcell value is not valid"
DataTypes are correct, it selects the right data too. The selections are pulled from one table, the actual selected value is pulled from another.
Any ideas?

Millions not that you'd be interested.

I am trying to get the Expiration Date from a card. Sending the following APDU command I get a bunch of data back in the response with a status code of 9000. CLA=00 INS=A4 P1=04 P2=00 LC=00 LE=00. As for getting the Expiration Date I am completely lost. A document I have here says the Expiration Date is in the tag 0x35. Should I be using the SELECT or GETDATA command for this? Where does the tag 0x35 come in?
Thanks,

I have a quick question for anyone who knows the answer to this:
Is there a difference (either performance or otherwise) between the following:
myObject.SomeEvent += new EventHandler(HandlingMethod);
and
myObject.SomeEvent += HandlingMethod;
Thanks
Steve

One is correct and the other isn't. You need to do the '+= new EventHandler' for non-anonymous methods. To unsubscribe from events you can use the -= .

The short answer is no, they are equivalent. A slightly longer answer is that the compiler recognises from the context that the second version requires the new EventHandler(...) and generates the same code for both.
For a really detailed answer take a look at a copy of Jeff Richter's "CLR via C#". But I warn you, that may tell you more than you wanted to know!

Thanks. I guessed that was what would happen but wanted clarification.

I'm writing a vs extension.
I need to add an item to the editor context menu if the class in current cursor position is inherited from another class (<b>Document</b> in my case).
public class MyDocument : Document
{
....
}
public class OtherDocument : NotReallyDocument
{
....
}
New menu item should be visible when user opens context menu (right-clicks) inside first class, and not visible in the second.
I can set the visibility in overriden OleMenuCommand.BeforeQueryStatus like this:
protected override void BeforeQueryStatus(object sender, EventArgs e)
{
((OleMenuCommand)sender).Visible = MyUtils.DetermineVisible();
((OleMenuCommand)sender).Enabled = MyUtils.DetermineVisible();
}
But how to determine that menu is opened from inside specific class?
(sorry for my bad english)

I'm having a really hard time finding information on programatically chaining sock proxies. I've been able to find proxies that are not anonymous but work well, so I figured the only way to find reliable and anonymous proxies is to chain 2 or more together non-anonymous proxies. But I want to be able to do it programatically in C#. Anyone have any suggestions or experience doing this? Its for scanning my company's competitor websites and gathering information regularly without being noticed.
Thanks,
Dave

While it's not unusual practice, it is still unethical and you could well be breaching Terms & Conditions.

I am writing to a 1K Mifare Card (RFID) in my windows application. How can I secure/personalize/encrypt this card so that only my application can read and write the data over it.
Thank You

Hi,
I am working in the same side. If you get any solution please inform me. One thing we can do is to make an encryption decryption class for the data. before storing the data to the tag you must convert it through some algorithm. For Example you can reverse the order of bits in each byte before storing to the tag. You must have to reverse the bytes again when you will read from the tag.
I am going through the different Issue. I am trying to store the data of 1433 bytes in 1K. if you have any idea of compressing the bytes please share that. Can we use the block 3 of each sector. I don't need the password. How can I override that.
Thank You.
Regards

This problem has been solved, the bug was somewhere else in my code. I am thankful to everybody who read my problem description.

I know this is simple but I just can't remember and can't find it. How do you change programatically which button is selected and which field has the cursor in it so the user doesn't have to keep tabbing or clicking.
