Hi Tiyani,
Thanks a lot. I think that I am moving along. I was able to parse the textboxes record and along the primary Id key that I need to the other form..
The other form has a table that consists of the foreign key from the parent table and other columns.
so when I click save on the child form, only the records from that are pertaining to the child table and dataset get saved to the database.
Not the record I parsed from the parent table..
How can I get all the input from the form the to get saved..
Here is my my saved function to look at to see where I go wrong:
Function Save() As Boolean
Dim saved As Boolean = False
Dim errors As Integer = 0
Me.Validate()
'Parent Tables where I get the record to load the other form
Me.RegistrationBindingSource.EndEdit()
Me.RegistrationTableAdapter.Update(Me.Commission1DataSet.Registration)
'child Table
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(Me.Case_fileDS.case_file)
Dim DeletedCaseFile As case_fileDS.case_fileDataTable = _
CType(Case_fileDS.case_file.GetChanges(Data.DataRowState.Deleted), case_fileDS.case_fileDataTable)
Dim NewCaseFile As case_fileDS.case_fileDataTable = _
CType(Case_fileDS.case_file.GetChanges(Data.DataRowState.Added), case_fileDS.case_fileDataTable)
Dim ModifiedCaseFile As case_fileDS.case_fileDataTable = _
CType(Case_fileDS.case_file.GetChanges(Data.DataRowState.Modified), case_fileDS.case_fileDataTable)
If Me.Case_fileDS.HasChanges Then
Try
If DeletedCaseFile IsNot Nothing Then
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(DeletedCaseFile)
End If
'Parent Tables
Me.RegistrationBindingSource.EndEdit()
Me.RegistrationTableAdapter.Update(Me.Commission1DataSet.Registration)
'child Table
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(Me.Case_fileDS.case_file)
If NewCaseFile IsNot Nothing Then
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(NewCaseFile)
End If
If ModifiedCaseFile IsNot Nothing Then
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(ModifiedCaseFile)
End If
Me.Case_fileDS.AcceptChanges()
'Parent Tables
Me.RegistrationBindingSource.EndEdit()
Me.RegistrationTableAdapter.Update(Me.Commission1DataSet.Registration)
'child Table
Me.Case_fileBindingSource.EndEdit()
Me.Case_fileTableAdapter.Update(Me.Case_fileDS.case_file)
Catch ex As Exception
MessageBox.Show("An error occurred during the update process")
' Add code to handle error here.
Finally
If DeletedCaseFile IsNot Nothing Then
DeletedCaseFile.Dispose()
End If
If NewCaseFile IsNot Nothing Then
NewCaseFile.Dispose()
End If
If ModifiedCaseFile IsNot Nothing Then
ModifiedCaseFile.Dispose()
End If
End Try
End If
Return True
End Function

MS-Access is not a client-server software. Its just like a file If one user locks this resource nobody can access until it gets free.

Not quite true. You can use MS Access in a multiuser environment. However it can be painful to use. You can be locked out if another user is doing something with records on the same page.
The usual way is to split the database into front and back ends. The font end sits on the client PC and the back end on a server. If I remember correctly, there is a tool in the Access menu that will split an existing database.
EDIT: Added quote.

There is all kinds of information on the web about VB.net and printing. All you have to do is Google for "vb.net printing[^]".
m2kannan wrote: is it support Ms access mutliuser operation ??
Yes, but not very well. You can run into some quirky problems and you have to make sure your code compacts the database every now then (when noone is using it!).

Hi,
Could anyone please help me with hiding the task bar when application runs. I did that with some code. But when I run another process from a button click, the task bar reappears. I want to disable the windows button too..
Thanks

You can't hide the taskbar. You CAN make your application sit on top of it, and it can also be made topmost. This is VERY hostile behaviour unless you're writing a kiosk style app.

a sincere thnaks for your reply.
All I want is that he shouldnot be able to access the start bar(to open my computer) and the taskbar(to open task manager). If I make my application sit on top of it, Will it serve my purpose?

Task Manager can be opened by right click >> task manager, or by pressing ctrl+alt+del
Do you want to Disable any one from going to Task Manager?
or
Do you want your form application to cover all the screen including the Start bar of Window?

Should not be able to click on my computer? Is that security needed? I doubt.
I guess you will find your answer in WeLoveVirusAPI()

that is purely a security needed. All I want is that user shouldn't be able to access any of the computer's saved files or other data accept the access to my application.

Sorry, This is still suspicious to me. If I suppose that what your are saying is 100% true, it is TOTALLY WRONG APPROACH.
I am not gonna help you regarding this any more. Sorry.

You cannot accomplish this task entirely from your code. This requires configuring Windows policies to handle most of this stuff. All of this is covered in the "Windows Resource Kit", under running Windows in a Kiosk mode. Get a copy from Amazon.com.

Yes and No
For the average user placing your application topmost will be enough, for the more advanced user there is NOTHING you can do (at least not legally). There is always a way to get the task manager at least if this is a app controlled with the keyboard (touchscreen is different).

what if i want to hide the task bar so as to create a game ,you know, like fifa etc
what do they do

As far as I know they don't do what you are trying to do, yes the task bar is 'hidden' but you can still access it (pres windows button or ctrl-escape). The reason its hidden is because the game is played full screen (maximized + topmost).
I don't play many games but I'v never played one where the game prevented me from accessing my start menu (or anything else on my pc) if I had that game would have been uninstalled faster than I can type this message .
I didn't say you can't hide the taskbar, I said you can't make it so that the user can't access it.
Out of curiosity will the user have a keyboard or will it be touchscreen?
(I ask because when its touchscreen you can do this (for the most part) since then you control what the user can press)

Those games don't use Windows the same way you do in your app. They pretty much take over the video card using DirectX and render everything themselves. You can still get to the Task Manager and Start bar though, with a simple Alt-Tab.

|
|
|

If you set the window state to topmost then yes, it will stay on top of the taskbar.
