If the service is logged in as anything other than LocalSystem, no, there isn't.
So what's stopping you from turning that little form app into something shows a little icon in the System Tray and can be called upon to show the downloaded file whenever necessary? Launching another application from that app will work very easily.

Hello all, does anyone have anyinformation on the following bug?
Steps:
1) put 3 textboxes on a form
2) in the leave event of textbox1 - disable textbox2
3) run the code - hit the tab key while in textbox1
4) the cursor remains in textbox1 - most likely because at the time of the keypress of the tab key textbox2 was enabled...now it's not so it lost where it should go...
I have a couple of work arounds but just curious if anyone knows of this and any "fix" plans...
Thank you.
Nathan

This is not a bug and there's no "fix". This is actually the expected behavior.
The focus does not get transferred to the next control until AFTER the Leave event handler is finished executing and the remaining event handlers (Validating, Validated, LostFocus, ...) are finished executing for the control losing the focus. By the time the execution gets to calling Focus on the next control (as a result of you hitting tab), the control is already disabled by you setting it's Enabled property to False.

Thank you for your reply...but it's not my expected behavior 
This is 1 work around (doesn't handle a shift-tab scenerio but handles a normal tab)
Private Sub TextBox2_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.Enter
If Not TextBox2.Enabled Then My.Computer.Keyboard.SendKeys("{TAB}")
End Sub
There's another way through the keyup event of the form...be nice if I didn't have to put this in either every control or form...
Thanks again.

This is klugy to say the least. I'd probably change this out for enabling/disabling the TabStop property of TextBox2 before I start using the problem-prone solution of SendKeys.

If you are refering to this...it doesn't work
Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave
TextBox2.TabStop = False
TextBox2.Enabled = False
End Sub

I said it would probably be something I would look at. I didn't say I had any code.

People always expect strange things from machinery 
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
TextBox2.TabStop = TextBox1.Text.Trim().Length > 0
'TextBox2.Enabled = TextBox2.TabStop for visual feedback.
End Sub
If you just want to move the focus to the "next" control, try this;
Me.ActiveControl.SelectNextControl(sender, True, False, True, True)

Well, good news is that you can inherit behavior. Next, go to the solution-explorer and right-click to "Add a new Item". From the dialog presented, choose "Inherited Form". If you press "OK", it'll ask what Form you want to inherit from. Point this to your "Form1". The same thing is possible with components.

Me.ActiveControl.SelectNextControl(sender, True, False, True, True) - didn't realize that was there but still doesn't work

Is it possible to disable textbox2 in another event, perhaps the text_changed event of textbox1? I know I've had to do that before, but never with the leave event. May not be possible for what you're trying to do.

I have a single row datagrid for adding records. I populate the grid dynamically with dynamic item templates because I have custom controls in the grid.
My ddl is a list of years. When a year is selected, I want to populate a textbox in the grid.
Problem: the entire grid disappears when I select a year
Code:
Public Class DynamicItemTemplate_DropDownList_Year
Implements ITemplate
Public Overridable Overloads Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn
Dim oDropDownList As DropDownList = New DropDownList
oDropDownList.AutoPostBack = True
oDropDownList.EnableViewState = False
AddHandler oDropDownList.Init, AddressOf BindDropDownList
AddHandler oDropDownList.SelectedIndexChanged, AddressOf ChangedDropDownList
container.Controls.Add(oDropDownList)
End Sub
Public Sub BindDropDownList(ByVal sender As Object, ByVal e As EventArgs)
Dim oDropDownList As DropDownList = CType(sender, DropDownList)
Dim container As DataGridItem = CType(oDropDownList.NamingContainer, DataGridItem)
Dim i As Integer
For i = 0 To 5
oDropDownList.Items.Add(New ListItem(CStr(CInt(Now.Year) + 5 - i), CStr(CInt(Now.Year) + 5 - i)))
Next
oDropDownList.SelectedValue = m_SelectedYear
End Sub
Public Sub ChangedDropDownList(ByVal sender As Object, ByVal e As EventArgs)
Dim oDropDownList As DropDownList = CType(sender, DropDownList)
Dim container As DataGridItem = CType(oDropDownList.NamingContainer, DataGridItem)
Dim oDescription As TextBox = CType(container.Cells(4).Controls(0), TextBox)
oDescription.Text = oDropDownList.SelectedItem.Text
End Sub
End Class

I have a strongly typed dataset (STD). I do a fill using the table adapter and the assoc. datatables are all fine and well. My questions involve how to best use the datarow (the strongly typed version- IE: dtTableName.TableNameRow).
Simple example below, just trying to illustrate my question.
I am creating a dsLabelFormats.dtFRCRow and then setting its value further down in code using a Directcast. The Directcast works, but is there a diff. method to do this without using a cast or a more efficient way of doing it? My code isn't doing a for each loop, I'm justing processing specific indexes.
Dim dr As dsLabelFormats.dtFRCRow = Nothing
_taFRC.Fill(_dsLabelFormats.dtFRC, vlngSerial, 1)
'Do some processing here and come up with specific records I want to process.
'Can this be done without a cast since I have a specific index on a STD.datatable?
dr = DirectCast(_dsLabelFormats.dtFRC.Rows(iIndex), dsLabelFormats.dtFRCRow)
With dr
'Set other variables here...
End With
Any suggestions, ideas, or 'constructive criticism' are always welcome.

The _dsLabelFormats.dtFRC.Rows(iIndex) is already of type dsLabelFormats.dtFRCRow therefore there should be no need to Cast it only assign it as follows :-
dr = _dsLabelFormats.dtFRC.Rows(iIndex)
So, in answer to the question is your code comment

I have Option Strict turned on so the following line doesn't work without a cast (because it's an implicit conversion). Is there another way to accomplish this without a cast? It's not a huge deal, just thought there might be a method or another way of doing it that I am not aware of.
dr = _dsLabelFormats.dtFRC.Rows(iIndex)
Any suggestions, ideas, or 'constructive criticism' are always welcome.

In that case, no, you will have to cast.

This question should go in the database forum, you will get better help there.

That would be TO_NUMBER.
As mentioned, this would propably belong to General Database forum.

i developed one project in vb.net i want to publish that project... i can't add my database during publish ....

If you are using a local file as a database like access, use relative paths and put it in the application directory. If you are using a database connected to the internet, stay away from using local IPS or LAN addresses.

It depends on what kind of database engine you're going to use. Compact Edition, Express Edition etc.

How get the full height of a window that has attached to a vertical scrollbar?
|
|
|
|
|
If you're talking about the client area of a form, there is no propery for it. Off the top of my head, you could put a Panel control on the form, making it as large as you want or dynamic as you want, then get the height of that instead.
