I think he means an application wide keypress event handler.

Have a look here[^]. I haven't tried it but it looks like it'll do what you want.

Hi,
yes you can create system-wide hotkeys.
My Code Rescue article[^] uses them (but does not mention it in the article itself).
There is some P/Invoke involved, calling Win32 functions.

Set your form's KeyPreview property to true then use the form's KeyDown, KeyPress or KeyUp events.

Bitmap class has several constructs. Choose the one that meets your needs

A snippet of code would be helpful.

You can use either Excel object Model or OleDb provider to read and write from excel document. As for sql server, you can use ADO.NET
|

I'm beging C#, pls write details code.
|

No one will write it for you. If you are new to it I suggest you search google for the terms I mentioned and read documentation

Why would you want to do this? I find processes that don't terminate when I want them to, well, rather annoying.

There is generally no legitimate need to do this. There are some of the critical operating system processes that are protected like this but user processes shouldn't need to do this.

is there any datepicker control in .net?if not can anyone tell me the code for the datepicker control to use in the application.

As far as I know there isn't a DatePicker control like you can use in Windows Applications (the one that looks like a ComboBox, and when dropped down, you see a calendar).
There is, however, a calendar control that can be used. The control can be added to your webform by adding:
<asp:calendar runat="server" id="myCalendar"></asp:calendar>

Hi,
I am new to .NET windows appln. I have 1 form frmadditem. frmadditem contains 1 textbox(txtcategory) and 1 Command Button(cmdselect). when I click cmdselect a window should pop up displaying list of categories and a select command button.when I select a category and click select command button, the category should go into the textbox(txtcategory).
Pls help me in doing this.

You need to create another form (frmpopup or something). Add a variable (_target) to hold the target text box. Ammend the constructor to take a TextBox argument and assign to this in the constructor i.e.
public partial class frmpopup : Form
{
private TextBox _target;
public frmpopup(TextBox target)
{
InitializeComponent();
_target = target;
}
}
Add your controls to this form and in the button's click event set _target.Text to whatever is correct.
In the cmdselect's click event on frmadditem, simply declare a new instance of frmpopup passing the textbox to the target argument.
