You have to change the following line of code.
Change: listBox1.Text = openFileDialog1.FileName
To: listBox1.Items.Add(openFileDialog1.FileName)

I've made a programme similar to the Windows Wordpad. and i want to use a msgbox to choose whether to save the text stored in richtextbox before the Form is closd
if the result of msgbox is Yes, a function 'savefile' will be called and after that the Form will be closed, if the result of the msgbox is No, the Form will be closed, and if result is Cancel, the Form will stay open.
how can I do it?
i've tried several times but it doesn't work.
please help. ~~
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
MsgBox("The Text in the file has been changed.Do you want to save it?", MsgBoxStyle.YesNoCancel, "Wordpad")
If MsgBoxResult.Yes Then
savefile()
e.Cancel = False
ElseIf MsgBoxResult.No Then
e.Cancel = False
ElseIf MsgBoxResult.Cancel Then
e.Cancel = True
End If
End If
End Sub

You need to include the message in the if statement:
If MessageBox.Show("Exit?", "Exit?", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Hand) = Windows.Forms.DialogResult.Cancel Then<br />
e.Cancel = True<br />
Else<br />
e.Cancel = False<br />
End If
Alternatively:
dim result as windows.forms.dialogresult<br />
<br />
result = MessageBox.Show("Exit?", "Exit?", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Hand)<br />
<br />
if result = Windows.Forms.DialogResult.Cancel then<br />
e.cancel = true<br />
elseif result = result = Windows.Forms.DialogResult.Yes then<br />
' do whatever<br />
else<br />
' do whatever<br />
end if
This way the cancel is dependant on the result.
P.S. Msgbox is old now, use messagebox.show, it's much more versatile and easier to create dialogs.

Can anyone offer some advise on how to improve performance (VB application, VS 2005) ...
An mdi window has a tab control that I'm using to show/hide child windows i.e. tabpage1 shows child windows 1,2,3, tabpage2 shows child windows 4,5,6 etc. I use a for loop to show the windows assigned to the selected tab and hide the ones that aren't.
However as the number of tabs & child windows grows, it becomes sluggish.
I cured this by actually assigning the child windows to the actual tabpages but then have problems maximising the child windows.
Anyone know of another solution I could try?

dose any one know about dos printing i want to print Barcode on epson Lq 680
code39 . need help

Dot matrix printers are not the best for barcodes. There dpi is too low. Having said that, to print barcodes from DOS you will need a printer module. I have purchased these in the past from Fontware

Sir/Madam,
I have a control ,I am passing that control in another function in the following way
like if i have invoked a datagrid , it's name is dg1.
sub abc()
{
binddata(dg1)
}
binddata(byval c as control)
{
'Now i want to assign the memory of c to datagrid control
dim d as datagrid
d = c
'But the above line shows error
}
'Please help.

amaneet wrote: dim d as datagrid
d = c
the type of c and d is not the same so you must use type casting to convert c to DataGrid
try this
d=(DataGrid)c

In VB6 you have NOT an Application object hence it complains about.
You can use a Timer control to obtain that stuff.

I am a newbie to vb.Net, I am self taught to a basic level on MSAccess. What i am trying to do is create an MDI application. Part of the application is to open a form with no data assigned to the controls, then open a form to set the query and return this result to the main form as the data. I m getting confused with datasets, tableadpators etc. Can someone point me in the right direction please. Also i want the filter form to be the topmost and hold the focus until a filter has been submitted or a cancel button clicked.
Confused newbie

Try this, should get you started on vb.net, if you want to go straight to database and skip the basics, i recommend episodes 8 and 9 of the beginner series. If you are new to vb.net though, it might be good to do the lot, they are great for learning.

Thankyou for the reply i will certainly look through these. I have been using a book from the library by 'WROX' to get me started. It explains datagrid views, and in general i understand the concept of binding the form to a table through using Access, but I am getting confused with the passing of a dataset back to a form. Is it as simple as Open form 1 with databind to the empty dataset. Open form 2 (filter/query form), on click handle event use parameters to fill dataset. return focus to form 1 and fill with bind to dataset which has info in it now/or not dependant on parameters.
Am i barking up the wrong tree? and is there an easy example of this i can view for guidance?
With regards to the filter form remaining on top, I have set this form to property ON TOP and I am using the If form.focused = false then form.focus() to keep the form active/focused and the topmost. This is primitive i know and it is not working on all occasions though, any pointers appreciated.

I am trying to bring up an Excel sheet when I click on a command button in Access. Can someone help me with the code?
PS I am very green at programming VBA.
Thank you,

You have not sid if you want it on a form in Access or to bring it up in another window.
I am not sure if you can do this in VBA, but in VB6 to load the spreadsheet into a form you place it in an OLE Container.
To bring Excel up in a seperate window you could try using the excel object by setting a reference in access to the excel.olb
