Hello, I only recently started working in VB, so now I'm having an obvious syntax-wise question:
I want to hook the .Click event of an object (sectionItem), inheriting from Panel to a Sub in my class.
In C# this would simply be sectionItem.Click += new EventHandler(mySub) , but in VB I'm a bit confused.
Could someone point me to the right actions?
Tnx

you can use AddHandler in VB.NET inorder to bind an event dynamically
Like,
<br />
AddHandler btnClose.Click, AddressOf btnClose_Click<br />
where btnClose is a button and btnClose_Click is the function or the event handler for that button when that button is clicked

Exactly what I needed. Thanks!

There are two options in VB:
1. As described by Mubashir.
2. Using a "Handles" clause:
e.g.,
Public Sub btnClose_Click(...<param list="" />...) Handles btnClose.Click
Some people prefer this more traditional VB way. However, of course this method only applies to cases that you know at design time.

You'd be better off asking this in the C++ forum. My C++ is pretty rusty, but this doesn't look like a COM componet you've written, or a .NET assembly. You're trying to use a C++ style class in managed code, and that just isn't going to work. It needs to be rewritten using CLI (Managed C++) in order to be used the way your doing it now. But, like I said, you're in the wrong forum for an accurate answer to this question.

hello,
How can I do a relation between a DataGrid and a ComboBox outside the DataGrid?
I need a help in syntax, using vb.net 2003 and sql server 2000
thank you

Not a very clear question, but if you bind a bindingsource to your datagridview, you can use the alter the currently selected row by changing the .Current property of the bindingsource.
I'm guessing you want to pick a row by selecting a value form your ComboBox, so you could do something like this:
Dim dgv As New DataGridView()
Dim bs As New BindingSource()
dgv.DataSource = bs
bs.DataSource = myDataSet
Dim cb As New ComboBox()
And then on SelectedIndexChange event of the combobox, you can set the bs.Current to the selected Value.

10x bertburtbort
but the question is that what i really need , the combobox brings its data from database.
when a selected value in the comboBox then its details displayed in the dataGrid
actually the data in datagrid is brought from an other table in the database
that is what i need
10x again

If someone could show me how i can loop the following code until end of the text file.
This would be much appreciated.
Dim FileReader As System.IO.StreamReader
FileReader = My.Computer.FileSystem.OpenTextFileReader("C:\SBL.txt")
Dim StringReader As String
StringReader = FileReader.ReadLine
Form2.ListView1.Items.Add(StringReader)

StringReader is a strange name for a string ?
Anyhow, you use a while loop. your string will return null ( Nothing in VB ) when the file is empty. Or you can use ReadAllText to get the strings out as a string array and use for each to iterate over that.

It's name is what it does, so i think that the name is relevant.

It's also the name of a class, I believe. It threw me for a second, that's all.

No, actually it's not. The string object doesn't read anything. It only contains data that was read.
If you want to write less confusing code, you should name the variable after what it contains or what it's used for, not after what some part of the code does when it uses the variable. Also, variables are generally not named with the first letter in capital, to distinguish them from classes and methods, and using data types in variable names is generally discouraged.

It doesn't contain a string, it is a string. Well, actually it's a reference to a string, but that's implied as reference type variables always are references.
It contains a line of text. What's wrong will calling it "line"?

Do While Not FileReader.EndOfStream
StringReader = FileReader.ReadLine
Form2.Listview1.items.add(StringReader)
Loop

This works like a charm THANKS
Now for another question...
Is there any way to input horizonaly in a Listview box?
Or is this just a matter of Formatting?.
All my data is going down instead of across.
I am viewing the Listview Box with Details set as true and Columns Headers ready and waiting.

Yes, you would first add an item (the leftmost item). The 'Add' method returns a listviewitem so you can get a reference to it by writing this:
Dim item As ListViewItem = ListView1.Items.Add(StringReader) Then to add an item to the next column you would use this:
item.SubItems.Add(SubItem) That's basically what you need to know.

THANKS Again
Have just been doing some more reading about Listview Boxs and have just figured out that what you have said is what i need to do.;)

This is my Code so far.....
Do While Not FileReader.EndOfStream
StringReader = FileReader.ReadLine
Form2.ListView1.Items.Add(StringReader)
'Adding Subitems
Dim item As ListViewItem = Form2.ListView1.Items.Add(StringReader)
Dim i As Integer
For i = 0 To 5
item.SubItems.Add(StringReader)
Next
Loop
Just a little bit of fine tuning....
What is happening is that the first item on the left is in the right spot, after that what should be the first sum-item it duplicated in the left column.
Then in the 3rd row this same item is in all the sub-item columns.
And the same thing happens to all the other sum-items, which then knoks out of wack all the other data.
It is surprising how writing something out and then thinking about it , you can come up with an answer;)
AND THE ANSWER is :-
move the Stringreader line into the for next loop and get rid of the line :-
Form2.ListView1.Items.Add(StringReader) as you don't need it twice in the code.
