Do you want to edit the data which you insert\add????If that is than the ans is

<br />
try <br />
con.open()<br />
Dim str As String = "update details set name='" & TextBox1.Text & "', address='" & TextBox2.Text & "', marks='" & Textbox.Text & "' where roll='" & Combobox1.Text & "'"<br />
            cmd = New OleDb.OleDbCommand(str, con)<br />
            cmd.ExecuteNonQuery()<br />
            MsgBox("Record updated", MsgBoxStyle.Information, "Update")<br />
<br />
        Catch ex As Exception<br />
            MsgBox(ex.ToString)<br />
        Finally<br />
            con.Close()<br />
        End Try<br />

This most certainly NOT the answer.

One, you have responded to the wrong post.

Two, you are excepting direct, unvalidated input from user controls that can, and will, expose you to sql injection attacks and other nasty results.

Three, it's VB

As long as you have the correct access rights opening a file on a remote computer is the same as opening one localy. Precisely how you open it will vary based on the task at hand.

It is correct that you will have to use the UNC path. Best practice is to place the file in a share that has appropriate rights set on it.

eg.

File.Open("\\RemoteComputerName\ShareName\FileName")

If you have knowledge, let others light their candles at it.

Once Form2 is closed it is only available until it goes out of scope, eg. until the end of the calling method if you used ShowDialog to display it.

In order to retain the value, add a property to Form1 and populate it with the TextBox Text from Form2 before it goes out of scope.

you can use the formclosing event for form2

Private Sub Form2_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

Form1.RichTextBox1.Text = Me.Textbox1.text

End Sub

List of installed applications (as shown by "Open With" dialog box of windows.)

Hi all,

We know that Windows "Open With" dialog box shows a complete list of installed applications that can open a file of some format. I want the same list of applications.

I could not find anyway by which I could use and customize the "Open With" dialog box of Windows. But please note that I don't want the list of every executable that is shown by "Add/Remove Program".

Is there a way to get the list of applications that can open file of some format (as shown by "Open With" dialog box of windows.)?

I can code in both C++ and C# but preferably C#.

Thanks and Regards
Aseem

The 'Open With' list is populated from entries in the registry.

Details of which registry keys you need to read can be found here[^].

For all you ever wanted to know about accessing the registry from .Net look here[^].

you did not ask a question someone could answer, so I'll ask some:
what is keeping you from implementing a little code snippet that does what you described?
and have you already decided which programming language and framework/environment you're going to use?

I only read code that is properly formatted, adding PRE tags is the easiest way to obtain that.

There is a property of the textbox known as textbox1_text_changed event. You can use that event to monitor both the input text boxes. And in the subroutine, you can give the addition of the values in both the text box.

It would be something like:

try{
textbox3.text = (Convert.ToInt32(textbox1.text)) + ((Convert.ToInt32(textbox2.text));
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}

I hope you got what I am trying to convey..

Your problem description makes no sense at all.

WHY are you using 5 timer controls?? All you need is one for the requirements you put in your post.

textboxes don't use timers, all they use is some real estate on some form.

you can tell what code should get executed when a particular timer event fires, so tell the one you choose to update the GUI and show current time. You'd better use a System.Windows.Forms.Timer for that, as that one ticks on the GUI thread!
