How about using the lost focus event? Does this solution answer to what you need to do?

I need help on a vb or vb.net code to open a text file data delimited either with comma, tab, space or pipe and read the content to a recordset or an access database.
The one i have done make use of a fixed field but i want the code to dynamically detect the no of columns(fields) in the text file and create the corresponding no of fields in access database table. Since the text files come from different sources

Hi,
I am trying to write a macro that will add a reference to a Visual Studio project. I am using the following code:
DTE.ExecuteCommand("Project.AddReference", "path to the DLL I want to reference")
This fails with the following error message (in a messagebox): Error HRESULT E_FAIL has been returned from a call to a COM component
Am I supposed to pass some other information with the path to the DLL?
Thanks,

Do a search for DShowNET on CP, it's in C# but the DLL can be compiled and referenced in VB, the projects are also in C# but it shouldn't be too difficult to convert to VB but it does exactly what you want.

Refer to Ed mention, if you want to convert from C# to vb.net, you can use this website[^].

Thank you guys I managed to build an video recording application in vb, but now I need one more favour from you. You see this application is to be used by doctors while they are performing operations so that they can record the video and take photographs and save the file to patient record. Now as you know during operations they cant use their hands to operate a computer so they need a foot operated paddle which if presed continuesly for 3 seconds the video should start recording and if pressed for one second it must take snapshots. I need to know how can I do this either by using serial port or the usb port.

I've problem with databinding in vb.net
The problem that i'm trying to set a text field of the databinding programmatically during runtime, the change appears on the form, but after save the new value is not saved to database, if i edit this field manually by the keyboard it is updated correctly.
here's my code, the Q_ID textbox is the filed belongs to HEADERBindingSource binding source, i try to set it by the value of newQ_id, anyone can tell me what is missing?
Private Sub Q_IDTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Q_IDTextBox.TextChanged
If newRecord = 1 Then
Q_IDTextBox.Text = newQ_id
newRecord = 0
Else
QueryQuestionaire()
End If
End Sub
Private Sub Q_HEADERBindingNavigatorSaveItem_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Q_HEADERBindingNavigatorSaveItem.Click
Me.Validate()
Me.Q_HEADERBindingSource.EndEdit()
Me.Q_HEADERTableAdapter.Update(Me.CSIDataSet.Q_HEA DER)
SaveQuestionaire()
End Sub
