Yes. That is exactly correct.
|
|
|
|

OK....I have just been doing the exact same thing and have it working great. Here is what you need to do:
1) Declare a public parameter as integer on the MDIParent form called something like OrderID or whatever
2) on the doubleclick event on the datagridview you need to:
-Get the correct orderID from the datagridview by specifying the correct index (column) value on the currentrow.
-Set the orderID parameter = ID found on the datagridview
3) on your table adapter that is called on the load event on the new form you need to pick up the MDIParent.OrderID in a parameterized fill query.
Let me know if you need some example syntax?
Let me know and I'll post some.

|

That's great... Could you please post some sample code? I have declared my variable, but it is not passing the id to the other form when I double click on the datagridview row...
Thanks for your assistance!

Just to clarify....by MDIParent I mean the MDI frame form. I have found that is a stable base to place parameters that need to be shared between forms.
here is a syntax example
Private Sub CustSalesOpportunityDataGridView_CellDoubleClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles CustSalesOpportunityDataGridView.CellDoubleClick<br />
<br />
<br />
MDIParent1.SalesOppToOpen = Me.CustSalesOpportunityDataGridView.Item(0, CustSalesOpportunityDataGridView.CurrentRow.Index).Value<br />
<br />
Dim SalesOpportunity As New NewSalesOpportunity()<br />
SalesOpportunity.Show()<br />
End Sub
This should work for you too

somebody tell me please how to shutdown the system from Visual Basic.NET Windows Application.
I need the code which allow me to do that ..
Actually I'v tried to do it by declaring for an API function and write ExitWindowsEx(....) but it works only for Log Off the system. 'EWX_SHUTDOWN' doesn’t work at all.
thanks for help
|
|
|
|
|
So lets see your code. We'll help you fix yours. We won't write your code for you.
|
|
|
|
|
'In general section
Const EWX_LOGOFF = 0
Const EWX_SHUTDOWN = 1
Const EWX_REBOOT = 2
Const EWX_FORCE = 4
Private Declare Function ExitWindowsEx Lib "user32" (ByVal uFlags As Integer, ByVal dwReserved As Integer) As Integer
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
ExitWindowsEx(EWX_FORCE Or EWX_SHUTDOWN, 0)
End Sub
'' Thanks in advance

OK. You really need to read the documentation on ExitWindowsEx[^]. If you use 0 for the second parameter, you can delay system shutdown considerably because this tells Windows that this is more-or-less an unplanned shutdown and XP and above will treat it like a crash. The ShutdownReason parameter is there for a reason, use it.
Also, if any application says that it's not OK to shutdown, it can abort the shutdown.
Your ignoring the return code. If this the return code is 0, then an error occured and you'll have to call the Win32 API function GetLastError to figure out why the call failed.
And last, but not least, you need to request the SE_SHUTDOWN_NAME privilege before you call ExitWindowsEx. You can find out how to do this by following the link on the ExitWindowsEx page for AdjustTokenPrivileges.

Hi
Is there a SIMPLE way to play MP3 and Midi files from within an application - Is there a class that can access media player or something?
What I want to be able to do is to Play, Stop, Adjust Master Volume, and perhaps have a Slider that I can drag to a position in a song.
I found some stuff in C#, but I need it in VB.Net.
I'm using VS2005

It's easy enough to translate C# to VB.NET. The two languages have far more in common than it would appear.
What's the C# code you have?

Would you like to ask a particular question about this stuff??
Or do you normally just go around to forums and post random, yet long, sections of code for no particular reason?

Hey Guys, this I need to do hopefully you guys can help.
I just need an application or service to browse to a certain page every five minutes. In my case it will be an asp page. Once the services browses to the page it just needs to close the and the asp page takes it from there and starts producing a grid. For instance when it connects properly the grid will show some green, but say the service gets stopped or the computer or server goes down then the grid will start showing red.
I hope that all made sense, if not just let me know and i will try to give some more info. I am just hoping someone can help.
Thanks, Travis

You can use WebRequest class in System.Net to browse a web page. Pass a querystring that is unique to your calling application. When you execute WebRequest.GetResponse(), you can be sure that the application is trying to connect to the web page.
In the ASP page, check from the querystring if the connection request is from your calling application, if yes, do your color thing.

I've got much better idea: Write it yourself.
When you get stuck at a certain point, then you can ask questions about the problem you're having. BTW, there is no "just do this" code that you can use to "connect" to an SQL, or any database, server. How you retrieve data from a database depends on what you want to do with the data and how the database is organized and even how your code is organized. There's lots of different ways to do this.

how to insert or save the entering values into msaccess from vb.net windows application?

http://www.google.com.au/search?hl=en&q=insert+save+access+vb.net&btnG=Search&meta=[^]
I trimmed a few words from your original question, but even the full question gave useful hits in google. We really can't offer anything more specific without knowing about your database, and you should read the generic stuff first.
