How do I display an mpeg or avi file on a form? Thanks for any help.

If this is for VB6, just use the 'Windows Media Player' ActiveX. To insert it in VB, go to the menu Project->Components, then select the 'Windows Media Player', then OK.
This will add a component that you can put on your form. Then, go through the properties of this component to load your movie.
Hope this helps !

is there a simple way to re-interpret the enter key as the tab key in dialogs?
in c++ there is a PreTranslateMsg() function which you can use to listen for an enter key-press, then resend the key-press as a tab key.. is there anything like this for vb?
thanks for any suggestions!
still a newb.. cut me some slack :P

use the KeyDown Event for each tab-enabled control. of course,this way, you have a lot of coding to do but it's the only way that i know

my VB6 application which calls and uses Excel works fine in Windows NT,2K and XP , but experiences problems when running on Windows 98. The system hangs and the message "System is dangerously low on resources" appear. I am assuming that this happen because Win98 does not have very secure Resource Management compared to NT based OS. Does anyone have any idea how to make my app work in Win98 ?

I'm trying to use drag & drop with a multiselection. I would like to copy the listview selected items on an other listview. I tried that :
<br />
Private Sub lstAllRole_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles lstAllRole.MouseDown<br />
lstAllRole.DoDragDrop(lstAllRole.SelectedItems, DragDropEffects.Copy)<br />
End Sub<br />
<br />
Private Sub lstRole_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles lstRole.DragEnter<br />
' If e.Data().GetDataPresent("System.Windows.Forms.ListView.ListViewItemCollection", False) Then<br />
If e.Data().GetDataPresent(lstAllRole.SelectedItems.GetType().ToString(), False) Then<br />
e.Effect() = DragDropEffects.Copy<br />
Else<br />
e.Effect() = DragDropEffects.None<br />
End If<br />
End Sub<br />
<br />
Private Sub lstRole_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles lstRole.DragDrop<br />
Dim obj As ListViewItem<br />
Dim objCol As Object<br />
<br />
<br />
For Each obj In e.Data.GetData(lstAllRole.SelectedItems.GetType().ToString(), False)<br />
lstRole.Items.Add(obj)<br />
Next<br />
End Sub<br />
The drag & drop works but not the copy. Does someone already do it ?
Thanks

Vipul,
You have now sent me three email messages asking how to do this. As I have previously pointed out, I do not reply to questions sent by email unless they relate to an article or code sample I have published.
You have posted the question to several different forums. If someone knows the answer, they will no doubt post a response. If you continue to email this question to me, I will report you for sending Spam.

Unfortunately Crystal Reports [^] has integrated with VS.NET. There is a lot of nice things about Crystal Reports, however they tend to have a lot of design flaw in previous versions of their software (e.g. 8.5).

Open a blank DB
Go to New
Import table
Navigate to the excel file you want imported
Click import
A wizard will now open asking things like "use top row as headings", etc. Follow the wizard and your table will be there
I've always heard that there was an idea behind Win ME... I still can't figure out what that was... anyboy know??? I;ve herad the idea was that it was supposed to be n operating system but I doubt this. - Brian Delahunty

Hmmm... you emailed me, but no message here.
Oh well - hopefully this helps. Sorry, I didn't realise you were asking for code, as your question only asks how to do it.
What I do (but perhaps I shouldn't spread this possibly bad practice) when I need code for VBA is open the program (in this case Access) and start recording a Macro. Then perform all the actions for importing the excel spreadsheet to an Access table. Stop recording the Macro, view the Macro code - it will give you everything 
Hope that is of more use to you

You can use the OleDb ADO.NET classes to access both MS Access and Excel datasources... it's works in pretty much the same way as the SqlDb classes when accessing a SQL Server database. The hard part is the connection, everything else is pretty much the same as importing/exporting data from other datasources...
See these knowledge base articles if you need more information and sample code...
HOW TO: Query and Display Excel Data by Using ASP.NET, ADO.NET and Visual Basic .NET - http://support.microsoft.com/default.aspx?scid=kb;en-us;Q311731
HOW TO: Use the ODBC .NET Managed Provider in Visual Basic .NET and Connection Strings - http://support.microsoft.com/default.aspx?scid=kb;en-us;Q310985
The last one is an example of connection strings for many different db types. It uses OdbcDb but can easily be changed to OleDb, if you please.

thnx

To disable the close button in a form, add this module to your project...
<br />
Option Explicit<br />
Option Private Module<br />
<br />
Public Declare Function GetSystemMenu Lib "user32" _<br />
(ByVal hwnd As Long, _<br />
ByVal bRevert As Long) As Long<br />
<br />
Public Declare Function RemoveMenu Lib "user32" _<br />
(ByVal hMenu As Long, _<br />
ByVal nPosition As Long, _<br />
ByVal wFlags As Long) As Long<br />
<br />
Public Const MF_BYPOSITION = &H400&<br />
<br />
Public Function DisableCloseButton(frm As Form) As Boolean<br />
<br />
Dim lHndSysMenu As Long<br />
Dim lAns1 As Long, lAns2 As Long<br />
<br />
lHndSysMenu = GetSystemMenu(frm.hwnd, 0)<br />
'//remove close button<br />
<br />
lAns1 = RemoveMenu(lHndSysMenu, 6, MF_BYPOSITION)<br />
'
<br />
lAns2 = RemoveMenu(lHndSysMenu, 5, MF_BYPOSITION)<br />
'//Return True if both calls were successful<br />
<br />
DisableCloseButton = (lAns1 <> 0 And lAns2 <> 0)<br />
<br />
End Function<br />
Then in the form_load() event, add this
<br />
Private Sub Form_Load()<br />
Dim retval as boolean<br />
<br />
retval = DisableCloseButton(frmName)<br />
<br />
End Sub<br />
as for starting the form maximized, there should be a property window for the form with an option labeled "WindowState", just set that to "2-Maximized"
or add this to the form_load() event as well
<br />
frmName.WindowState = 2<br />
