ComboBox c = (ComboBox)sender;
label1.Text = c.Text;

I know how to get the current time but,
After I giv the alarm time,
I don't know how to check if the time of alarm has come,I tried in while loop
but the application crashed.
And one more thing, how can I do that the time is displaying in label1 on my
window.

What about a Timer?
Displaying the time should be something like label.Text = DateTime.Now.ToString("HH:mm:ss");

Thaks, but I know how to display it to label but i don't know how to display always the current time in label. How can i do this, and how can i check if the current time equal the alarm time. And what you mean by 'Timer'??
PS I think that is my main problem.

You need to learn how the Timer class works, especially in C#.
Here is one article you should read to get the basic understandings: click
To display the current time you just need a timer with an interval of 1000ms (i.e. one second).
In its callback you just do the Label.text = ...
For an alarm it's better to calculate the difference between the alarm time and the current time.
C# provides a class named TimeSpan to calculate the difference. You can use the values of this class to set the proper interval for your timer object.

I'm assuming you wanted to ask a question. I'm also assuming your question was something like "How do I read and execute a bunch of .sql files using C#?"
If my assumptions are correct then you may want to look at: Running SQL Scripts with a .NET application[^]
Does this help?

Hi,
It's my first project in c#. I have to make an app which would export data from xls to my database. It should also validate the data from xls...
I've been working with java and for configuration purposes I've been using spring and xml - then user could change the spring file without again compilation of the apllication...
What do u use in similar projects under c#? Do u have an links?

Use application configuration files, which are XML files that contain configuration information for .NET applications. You can add an app.config (or web.config for ASP.NET applications) to your project and then use classes in the System.Configuration namespace to access it.

Thanks, I've read some articles covering System.Configuration. Now I have simple problem:
I want to have simple list of strings in ArrayList, these r those strings:
aas
bsd
cds
4fe
5
What should I write in app.config? (how u write lists and which handler do u provide for this collection)?
<sectiongroup name="settings">
and then
<settings>
<mylist>
????????????????
and finally in some core file:
ArrayList nvc = (ArrayList)ConfigurationSettings.GetConfig("settings/dbSettings");
MessageBox.Show("Connection String is " + nvc[0].ToString());
I've tried different ways but it doesn't work...

Dear All,
i have developed a desktop based application using C#.NET.
In this application, i wants to enable & disable the USB drives programatically. ie, enable the USB port before the application starts using it & disable it after the use.
I need to achieve the same when the application is running in a login, who doesn't have administrative rights.
Is it possible to achieve the same using .NET framework?
Do any one knows how to implement this. If so, please inform me.
Best Regards,
Abhilash Chandran

I don't know what you mean by that.

Yes, parameters are a good way. They reduce the attack surface of your application which reduces the chances of being susceptible to a SQL Injection Attack.

public int VariableName <br />
{<br />
get { return variablename; }<br />
set { variablename = value; }<br />
}<br />
string qry = "Select abc From table Where xyz = " + this.VariableName;

Never ever do that for two reasons:
1. It makes your code susceptable to a SQL injection attack.
2. You cannot concatenate an int onto a string.

that was a simple demo. while in real conversions are made.
Thanks for suggestions.

Where the values come from when you construct the query is quite irrelevant. It's just another non-parameterized query.
A parameterized query is generally preferred.

Hello,
Is not there any method available to make an Array with only Unique elements in C# ? after calling the method, the Array must get rid of all duplicate elements.
Thanks

Have a look at the free PowerCollections library.

You have to register to access it but registration is free and you won't get spammed!
Oh, I'm assuming you're using .NET 2.0?
