I have not idea about download login form of MSAccess database
but you can pick a login template from Visual Studio IDE
follow steps
Go to Menu Project--->Add New Item
a dialog box is open. Choose "Login Form" from Template section, Give appropriate Name and Click on Add button. In this way you can add a login form in your application
Hope this helps

hi all,
am using VS 2005, i have one issue on search buttons. The problem is my form contains 4 search buttons each search button searching the values depends on table values . For Exp TicketNumber,UnitNumber,CompanyName,SerialNumber.
In this case only one search button working properly my code is........
Dim f_LookupNonRev As New LookUpNonRev
Dim strTicketNumber As String = ""
f_LookupNonRev.dt_parentdata = dt_nonrev
f_LookupNonRev.ShowDialog()
If Not IsNothing(f_LookupNonRev.SearchID) Then StrTicketNumber = f_LookupNonRev.SearchID
f_LookupNonRev.Close()
If StrTicketNumber.Trim <> "" Then bs_nonrev.Position = bs_nonrev.Find("TicketNumber", StrTicketNumber)
serch button
Public Property SearchID() As String
Get
SearchID = strTicketNumber
End Get
Set(ByVal Value As String)
strTicketNumber = Value
End Set
End Property
If dgvDataView.SelectedRows.Count > 0 Then
SearchID = dgvDataView.SelectedRows(0).Cells("TicketNumber").Value()
End If

Hi,
this is only part of the relevant code, making it difficult or impossible to help you.
What are your buttons names?
Where are their Click handlers?
What is bs_nonrev?
one button works properly, but what are the other 3 doing? Be specific on the symptoms!

I written an application (With the help of other people) to grab information from a SQL database, and display it on screen, so that is is editable, deletable and amendable.
How would I go about pasting a set line (Of the Data Grid) into an underlying application (Like a webform?)
Any help is appreciated.
Cheers

What do you mean by an "underlying" application? A web form is not an application, that would rather be a browser...
Perhaps you should explain what it is that you are trying to accomplish, instead of asking for what you think may be the solution...
Despite everything, the person most likely to be fooling you next is yourself.

If you want to achieve this you are going to have to manage the copy paste operation yourself (or at least the copy part). You will need to read the row from the data grid, construct an object (probably a delimited string) for the data and place it in the clipboard.
The paste part is up to your target.

Hi experts,
i am developing a window application, using VS 2005, i created a user control that contain a Combobox and error provider for my combo.
Everything worked just fine until i needed to use the event SelectedindexChange, in fact, in my form i have my user control(containing Combo box) and a checked list box. For each value in my Combo box i have to load different values into my checked list box
Therefore, i need to use the event selectedindexchange in my form
can anyone teach me please how to create an event in my form to fire a function in my usercontrol when the index is changed? If there is another way hope to share it.
the code of my user control (if there is any remarks or anything that i could be written much better or missing i will be thankful to tell me)

Out of curiosity I did, first hit, this question 
When I have used a user control I put all the management for the control in the code behind the control (it worked Ok for the rare occasions I have needed a UC)

You could, but you shouldn't, as the code gets harder to follow and maintain. Handle the even in the form where the control is that causes the event, and from that event handler just call a method (or set a property) in your user conrol.
Despite everything, the person most likely to be fooling you next is yourself.

Thanks Guys.
in fact i found it, all i have to do is:
declaring a new event to my user control
Public Event Selected_Index_Changed()
and this
Public Sub My_ComboBox_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles My_ComboBox.SelectedIndexChanged
Index = Me.My_ComboBox.SelectedIndex
RaiseEvent Selected_Index_Changed()
End Sub
so when the combo box change index the user control raiseevent Selected_Index_Changed
this way i can use it in the original form
sorry if my post was to long just wanted to share my ideas and make the code much more better
thanks again.

For reasons too boring to go into, I need to make a set of textboxes open depending on the user input.
for example, I have TextBox1, TextBox2, TextBox3 etc up to 7.
I have a combobox that is populated 1 to 7
User selects 6 for example, I want textboxes 1-6 to become visible.
I am trying something like this...
For i = 1 to intNumOfBoxes
TextBox(a).Visible = True
Next
Of course it isn't working!
I tried TextBox & intNumOfBoxes, still no joy.
I know it is late and I am being dim, but any suggestions?

Declare a control TextBox using the contactenated string as the name. I think this works.
Dim oTB as new textbox("textboxname")

Doesnt seem to work.
It say "Too many Arguments to Public Sub New()"
However...
I tried this
Dim oTB As New TextBox
For a = 1 To INumOfBox2
oTB.Name = "TextBox"
oTB.Name = oTB.Name & Str(a)
oTB.Visible = True
Next
It accepts it, but doesn't make visible the Text Boxes

I think you will need to use reflections to get at the textbox (or a case statement which is simpler but a kludge)
dim oTB as textbox
Select Case cbo.selectedvalue
case 1....
otb = txtBox1

This instantiates as new textbox which you then assign a name to and discard.

Thanks, I will try that in the morning though, 3.21am and brain starting to fry.
I can see a way of doing it that is long winded, so I hope that your method works!
