Hello Everyone, sorry to bother you, this can be a stupid request but I am really stuck up. I have a windows form (let's call it Form1) which needs to be able to catch an event from another form (let's call it Form2). Form2 is launched from within a method in Form1. Form2 has just two buttons that can be clicked by the user, and I need to catch those events from Form1.
Is it possible? and how can I do it without much trouble?
Thanks in advance and sorry for my bad english.

The 'dirty' method would be to make the two buttons (the fields) public. Then Form1 could bind the event directly:
Form2 f = new Form2();
f.button1.Click += ...;
f.button2.Click += ...;
Better would be to make public event in Form2 and letting Form1 catch those instead:
public event EventHandler Button1Clicked;
public event EventHandler Button2Clicked;
private void button1_Click(object sender, EventArgs e) {
if (Button1Clicked != null)
Button1Clicked(this, EventArgs.Empty);
}
Form2 f = new Form2();
f.Button1Clicked += ...;
f.Button2Clicked += ...;

sorry to bother you again, but even if it works in C# i can't get it working in VB.NET. Any ideas if there's some other way to do this (and in VB)?
Thanks again

This code works in Visual Studio 2003. Form1 has a ListBox on it. Form2 has two command buttons named btn1frm2 and btn2frm2. Programatically create two command buttons on form1 and set them equal to the command buttons on form2. Now you can capture the events from the buttons on form2 in the event handlers for the buttons you programatically created on form1 as follows:
Private WithEvents b1f2 As Button<br />
Private WithEvents b2f2 As Button<br />
<br />
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
<br />
Dim form2 As New Form2<br />
<br />
b1f2 = form2.btn1frm2<br />
b2f2 = form2.btn2frm2<br />
AddHandler b1f2.Click, AddressOf b1f2_click<br />
AddHandler b2f2.Click, AddressOf b2f2_click<br />
<br />
form2.Show()<br />
<br />
End Sub<br />
<br />
Private Sub b1f2_click(ByVal sender As System.Object, ByVal e As System.EventArgs)<br />
ListBox1.Items.Add("1")<br />
End Sub<br />
<br />
Private Sub b2f2_click(ByVal sender As System.Object, ByVal e As System.EventArgs)<br />
ListBox1.Items.Add("2")<br />
End Sub<br />

hi
if you want to select the max value in the column A :
SqlSelectCommand1 = New System.Data.SqlClient.SqlCommand("select max(A)from TableName", SqlConnection1)
SqlConnection1.Open()
Dim max As Integer = CType(SqlSelectCommand1.ExecuteScalar(), Integer)
SqlConnection1.Close()

thnx for your reply. However, I do not want to find the max value from a particular field. I need to find the maximum of the value from the fields A to F. say A has a value 1, B-2, C-3, D-4, E-5, F-3, then I need to find the value 5 using a query or a piece of code. Remember A, B, C, D, E & F are field names and not records.
With Best Regards,
Mayur

Well then execute the query 6 times or just make one select to get the maximum of all fields together and then use Math.Max to determine the biggest ones among these.

Thnx Robert. Maybe I will try and explain it once again.
Consider a table having A - Z fields storing integer values. Therefore each record in this table will have A - Z fields. I need to find the maximum value for each record from the fields A - Z.
Can you plz help me with this.

There is no simple way of doing that, as the database is badly designed.
For the fields A to C, it would be
select case when A > B then (case when A > C then A else C end) else (case when B > C then B else C end) end from ...
Imagine what that would look like for A to Z... The query would most likely be too complex to even run...
The values should be stored in separate records (in a separate table) if you want to be able to aggregate them efficiently.

Thanks Guffa. I understand what you mean to say. Can you suggest a way this can be done using vb.net. As in reading a record and then finding the maximum value through code...

You have badly designed the database, and there is no easy way to aggregate this data.
Maybe you could explain what you are trying to achieve, and somebody could make some suggestions on how to go about it better.

Select Case keyData
Case Keys.Up, Keys.Down, Keys.Left, Keys.Right ' (Left/Right also navigate controls)
If keyData = Keys.Up Then
Button1.PerformClick()
ElseIf keyData = Keys.Down Then

Hi,
assumming you have a DataTable bound to your grid you will have to set the RowFilter of its DefaultView to a string representing your cirteria. A description on how the filter must look like can be found here[^]. You could also have a look at one of my articles[^] dealing with this or probably even just use the component.
