You can use the KeyPress event of your textbox field to override the characters that are entered, forcing the character at a certain position in the string to be a particular character. You can also limit the number of characters enetered. The following example is for a date entry field:
With YourTextBox
If Len(.Text) >= 10 And Not e.KeyChar = ChrW(8) Then
MsgBox("Maximum number of input characters is 10!", _
MsgBoxStyle.Information, "Invalid Data Input")
Exit Sub
ElseIf Len(.Text) = 2 And Not e.KeyChar = ChrW(8) And Not e.KeyChar = ChrW(47) Then
.Text = .Text & "/"
.Select(.Text.Length, 0)
ElseIf Len(.Text) = 5 And Not e.KeyChar = ChrW(8) And Not e.KeyChar = ChrW(47) Then
.Text = .Text & "/"
.Select(.Text.Length, 0)
Else
End If
End With
I use something similar to this to validate entry on all my fields. It is used in combination with the TextChanged and Validating events. I have stripped out code for setting errorproviders etc..

hie ,
i need to make a listview with a popup menu BUT i need to show the "properties" of the selected item like in explorer.Problem is with this code :
Private Sub ListView2_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single)<br />
<br />
If Button = vbRightButton Then<br />
'If ListView2.SelectedItem = ListView2.HitTest(x, y) Then<br />
PopupMenu mnuMyMenu, vbPopupMenuRightButton<br />
'End If<br />
End If<br />
End Sub
With the 'If ListView2.Selec.... commented i just get a popup menu no matter where i click , like white space.Also if the user cliked item1 , then right-clicked in any white space.. the popup shows up with the listview SELECTED property set to item1 i Need to show the menu ONLY if the user click an ITEM!! but then with comments removed i get a runtime error 91 , object variable or with block nt set ONLY IF I CLICK A WHITE SPACE>> if i click an ITEM EVERYTHING RUNS SMOOTHLY!!
Option 2: i found http://vb-helper.com/howto_listview_right_click_header.html[^] site , it uses a VC type procedure , i do know VC , BUT its for getting a context menu on the header of the listview. The message the programm looks for is "WM_PARENTNOTIFY" and then a "WM_RBUTTONDOWN" wParam.Now I DONT KNOW THE MESSAGE for items!! 
Could some one help me HERE!!

ok , this is quite embarassing .. .. all i did was add a set and everything worked!!! (yes i did declare the variable!)
anyway , heres the code so no one else makes any mistakes!
Private Sub ListView2_MouseUp(Button As Integer, Shift As Integer, x As Single, y As Single)<br />
If Button = 2 Then<br />
Set lst = ListView2.HitTest(x, y)<br />
If Not lst Is Nothing Then<br />
PopupMenu mnuMain, vbPopupMenuRightButton<br />
End If<br />
End If<br />
End Sub
1. Use it ONLY in the MOUSEUP event
2. I dont think vbPopupMenuRightButton makes much of a difference , i any1 knows tell me!!
3. DONT FORGET SET
Hope that helps some1

I'm writing a little program just for personal use which has all my favourite programs and accessories links on it, sort of like a second taskbar if you get me.
All is going well, however now I want to make my program so its always on top, but besides that I want to make it so no other windows of any other program are going behind it. E.g How all program windows stop where the taskbar starts, they dont go behind the actual taskbar. My program loads on the right side of my screen, just like the new vista sidebar does, or google desktop sidebar. Any ideas as how I can achieve this?
If I havent explained correctly myself please let me know.
In a nutshell, I want other programs running to 'bud up' to the side of my 'sidebar', instead of just going completely behind it while it is always on top.
Regards,
litestep23.

Hi all,
I'm having a weird problems with my email.
I'm using System.web.mail namespace to send the email.
Everything went well until I tried to import the message body from microsoft words.
What I did was change the message body with the imported text from word.
The message example is like this
Dear Dr. Who,
This is just a test. Please click the following link.
www.testing.com
You are given a password
Thank you,
Eagertolearn
When I test it to send it to hotmail, yahoo and gmail, it's showing only the "given a password" line. Everything else is not shown. When I tried to send it to company's email, it's working really well. Anyone knows what i'm doing wrong?

Could it be that the message contains XML tags and it's being stripped ?

Nope, it's plain text.

but you mentioned that you imported this from Microsoft Word? It adds a lof of its own formatting. you should try this in notepad and then try.
Thanks.

Have you looked at what Word puts into an HTML document? It throws in tons of stuff that is useless to you but Word needs in case it needs to open the document again and edit it. You'd be better off writing your HTML email from scratch and, from what you posted here, you can do it in less than 10 lines...

I don't think it's an HTML document. I import it as text and i don't see any other text other than the message itself.
Yeah, I think I'm going to try to write from scratch.
Thanks Dave

You can use SqlDataAdapter or SqlCommand objects to place your data in your DataSet.
The DataAdapter has the advantage that you can use the same object to update your database tables.
Search your help files for information on these objects.

It's not that easy!
First you need to create a connection object and set it's properties, connection string etc.
Then you need to setup your dataset tables and relationships/constraints etc
Then you can create your DataAdapters or command objects to retrieve your data and place it in your dataset. From there, you can bind it to your form controls.
If you are a beginner, as you stated, you will learn more by finding out for yourself by reading the help topics in Visual Studio or MSDN.
I will help you with any particular thing you don't understand but it is far too complicated to just give you all the code for what you ask.
You have to do some of the work yourself!

You need to do something like this:
Private Sub POPULATE_Controls
With YourDataSet.Tables("YourTable").Rows _
(Me.BindingContext(YourDataSet, "YourTable").Position)
ControlName.Text = IIf(IsDBNull(.Item("YourFieldName")), "", _
.Item("YourFieldName"))
'Repeat for each field/control
End With
End Sub
Unless you are doing it all in the designer (datasets etc) then you can bind through the properties window. I always do it in code.
To view the next record, you will need to create your navigation buttons and adjust the BindingContext position, then call POPULATE_Controls again.

Hi
I have a DataGrid with comboboxes (inherited from DataGridTextBoxColumn) and I'm woundering what methods or something runs when a user clicks in the DataGrid or ComboBox. In the comboboxes I use the KeyUp event for the user to choose an item in the combobox. When I choose an item with keys nothing happens, but when I click and choose an item in my combobox a new row appear in the DataGrid and that is what I want to happen.
Is there someway I can get the same thing to happen whether I click or press
keys in the combobox.
Here is the code for using the keys to choose an item in the comboboxes
Private Shadows Sub IntelliCmb_KeyUp(ByVal sender As Object, _
ByVal e As System.Windows.Forms.KeyEventArgs) Handles ColumnComboBox.KeyUp
Dim index As Integer
Dim actual As String
Dim found As String
If ((e.KeyCode = Keys.Back) Or _
(e.KeyCode = Keys.Left) Or _
(e.KeyCode = Keys.Right) Or _
(e.KeyCode = Keys.Up) Or _
(e.KeyCode = Keys.Down) Or _
(e.KeyCode = Keys.PageUp) Or _
(e.KeyCode = Keys.PageDown) Or _
(e.KeyCode = Keys.Home) Or _
(e.KeyCode = Keys.ShiftKey) Or _
(e.KeyCode = Keys.Tab) Or _
(e.KeyCode = Keys.F2) Or _
(e.KeyCode = Keys.End)) Then
Return
End If
If e.KeyCode = Keys.Enter Or e.KeyCode = Keys.Delete Then
If ColumnComboBox.Text = "" Then
mblnEditing = True
End If
Return
End If
actual = ColumnComboBox.Text
index = ColumnComboBox.FindString(actual)
If (index > -1) Then
ColumnComboBox.SelectedIndex = index
ColumnComboBox.SelectionStart = actual.Length
ColumnComboBox.SelectionLength = found.Length
If ColumnComboBox.SelectedIndex <> 0 Then
mblnEditing = True
End If
End If
Please, I need help!!!!

Hi, I have a list view which display the following data:
ID Name Sex
001 John Male
002 Michael Male
003 Janny Female
For example: why I click on the second row (ID: 002) it will return all information (ID, Name and sex) to the text box and I can update it. Does anyone has the sample to identify which row is select in list view. I need the code in vb.net.
Thank

ListView.SelectedIndices will return the index of the seletced row.
Example:
Integer = myListView.SelectedIndices
If multi-select is enabled, it will return an index for each row selected. In which case you would use an array to store the values.
