What I like to know is what code would I need to have if when I press a button it will tell the system to scan for new hardware? Basically the same as going into Device manager and telling it to scan for new hardware. If you ask why I'll go into more detail what I wan't to do.
P.S It's been about two years since I've done VB so I'm more then rusty on it.
Thanks,
Pat

Pat,
Somthing like this: (In VB.Net.)
(Imports System.Runtime.InteropServices)
Public Const CM_LOCATE_DEVNODE_NORMAL = &H0
Public Const CR_SUCCESS = &H0
Public Const CR_OUT_OF_MEMORY = &H2
Public Const CR_INVALID_DATA = &H1F
Public Const CR_INVALID_MACHINENAME = &H2F
Public Const CR_ACCESS_DENIED = &H33
<DllImport("cfgmgr32.dll", SetLastError:=True)> _
Public Shared Function CM_Locate_DevNode( _
ByRef pdnDevInst As IntPtr, _
ByVal pDeviceID As String, _
ByVal ulFlags As Integer) _
As Integer
End Function
<DllImport("cfgmgr32.dll", SetLastError:=True)> _
Public Shared Function CM_Reenumerate_DevNode( _
ByVal dnDevInst As IntPtr, _
ByVal ulFlags As Integer) _
As Integer
End Function
Private Function ScanForHardwareChanges() As Boolean
Dim status As Integer
Dim hDevInst As IntPtr
status = CM_Locate_DevNode(hDevInst, vbNullString, CM_LOCATE_DEVNODE_NORMAL)
'Debug.WriteLine("CM_Locate Status: " & status)
If status <> CR_SUCCESS Then
Return False
End If
status = CM_Reenumerate_DevNode(hDevInst, 0)
'Debug.WriteLine("CM_Reenumerate Status: " & status)
If status <> CR_SUCCESS Then
Return False
End If
Return True
End Function
Progload

Thankyou very much. Now lets see if I can actually do something with this. =)

My form has a BindingSource object which was added using the Form Designer with the AllowNew property set to True and the DataSource property assigned to a typed DataSet. The typed DataSet has some default column values.
When the form loads I call 'Me.SharedBindingSource.AddNew()' so as to have a single row of data with the default column values ready for displaying on forms. However, on calling the method I always get a System.NotSupportedException.
I have used this before but I cannot tell why it is not working this time around.
Exception details:
System.NotSupportedException was unhandled by user code
Message="Specified method is not supported."
Source="System.Data"

Thanks

I discovered that the exception was raised because I had not yet assigned a value to the BindingSource.DataMember property.
I had intended/hoped that AddNew() would add a new row to each DataTable in the DataSet but obviously it only acts upon the assigned DataMember.

How do I create an install program. My program is written in 2003.net and want to run it on a machine that does not have VB loaded on it.
Any ideas? In VB6 I could create an install program? How do I do that in 2003

You only need to install .NetFrameworkRuntime (dotnextfx) file on the destination machine. You may use a third party installer, This is the case I always do, I don't know much about Setup projects.

Have hit a bit of a brick wall regarding embedding an application inside a web form, i.e. have a page with text and then say the calculator down the right hand side. Is this even possible to do? Essentially I'd like to be able to do this what was explained in http://www.codeproject.com/vb/net/ByPassAutomation.asp", but in a web form rather than a windows form.
Any suggestions?
Many Thanks,
Ken.

Hello.
I´m a VB programing and I´m from Brazil.
I need some help with DBF database. I already created a DBF code in VB, but I don´t know how to set size of a field(columns).
For example: When I created a DBF, it came with fields with width 20 and type adNumeric, but I want it with width the size equal 5 and type adNumeric.
How can I do it in VB6?
below it´s my code to generate a DBF
Function fCriaDBF(sPATH As String, sNome As String, vCampos As Variant) As Boolean
Dim cat As New ADOX.Catalog
Dim tbl As New ADOX.Table
Dim i As Integer
Set cat = New ADOX.Catalog
cat.ActiveConnection = "Provider=Microsoft.JET.OLEDB.4.0;Data Source=c:\tmp;Extended Properties=Dbase 5.0;"
Set tbl = New ADOX.Table
With tbl
.Name = sNome
Set .ParentCatalog = cat
With .Columns
For i = 0 To UBound(vCampos)
.Append vCampos(i), adNumeric, CLng(5)
.Item(vCampos(i)).NumericScale = 0
.Item(vCampos(i)).DefinedSize = CByte(5)
.Item(vCampos(i)).Precision = CLng(5)
Next
End With
End With
cat.Tables.Append tbl
Set cat = Nothing
end function
Anyone Help me!
Tanks

Hi,
Plz tell me how can i, firstly, add the data from the datagrid to the dataset. Secondly, how can i update the data from the datagrid to the dataset. i.e. all the settings or updations must be saved to the dataset.
Thanks.
Plz anybody answer to my question.![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

If you bind the datagrid to the dataset, and make sure that the ReadOnly property of the datagrid is set to false, the dataset is updatable by the datagrid. Then you should write
DataAdapter1.Update(DataSet1)
DataSet1.AcceptChanges()
to have the changes take effect in the database....

Can someone tell me what is wrong with this code? The error I'm getting is: "Error #380 was generated by ListItems. Invalid Property value."
I’m trying to place a database table’s information on a listview control. Where the column names are the table’s field names.
Here is the code:
Private Sub List_Fields_In_Table(cnnDB As ADODB.Connection, strTable As String)
On Error GoTo List_Fields_In_Table_Err
Dim itmX As ListItem
Dim clmX As ColumnHeader
Dim Idx As Integer
Dim fld As ADODB.Field
lvTblCols.ListItems.Clear
Set rstSchema = New ADODB.Recordset
strSQL = "SELECT " & strTable & ".* FROM " & strTable & ";"
'Retrieve table field schema
rstSchema.Open strTable, cnnDB, , , adCmdTable
lvTblCols.ColumnHeaders.Clear
lvTblCols.ListItems.Clear
lvTblCols.View = lvwReport
lvTblCols.BorderStyle = ccFixedSingle
Idx = 1
For Each fld In rstSchema.Fields
'Place the Field name on the column, with an index to the column.
'Name the column with the fld.name
Set clmX = lvTblCols.ColumnHeaders.Add(Idx, fld.Name, fld.Name)
'Place the value in the field under the its field name
Set itmX = lvTblCols.ListItems.Add(Idx, fld.Name, fld.Value)
'I get the error here.
itmX.SubItems(lvTblCols.ColumnHeaders(fld.Name).SubItemIndex) = fld.Value
Idx = Idx + 1
Next fld
List_Fields_In_Table_Exit:
On Error Resume Next
rstSchema.Close
Set rstSchema = Nothing
Exit Sub
List_Fields_In_Table_Err:
Msg = "Error in frmPictures - List_Fields_In_Table subroutine. " & vbCr & _
"Error # " & Str(Err.Number) & " was generated by " _
& Err.Source & vbCr & Err.Description
MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext
Resume List_Fields_In_Table_Exit
End Sub
This is just a variable version of:
Make sure ListView control is in report view.
ListView1.View = lvwReport
' Add three columns.
ListView1.ColumnHeaders.Add , "Name", "Name"
ListView1.ColumnHeaders.Add , "Address", "Address"
ListView1.ColumnHeaders.Add , "Phone", "Phone"
' Add ListItem objects to the control.
Dim itmX As ListItem
' Add names to column 1.
Set itmX= ListView1.ListItems.Add(1, "Mary", "Mary")
' Use the SubItemIndex to associate the SubItem with the correct
' ColumnHeader. Use the key ("Address") to specify the right
' ColumnHeader.
itmX.SubItems(ListView1.ColumnHeaders("Address").SubItemIndex) _
= "212 Grunge Street"
' Use the ColumnHeader key to associate the SubItems string
' with the correct ColumnHeader.
itmX.SubItems(ListView1.ColumnHeaders("Phone").SubItemIndex) _
= "555-1212"
Set itmX = ListView1.ListItems.Add(2, "Bill", "Bill")
itmX.SubItems(ListView1.ColumnHeaders("Address").SubItemIndex) _
= "101 Pacific Way"
itmX.SubItems(ListView1.ColumnHeaders("Phone").SubItemIndex) _
= "555-7879"
Set itmX= ListView1.ListItems.Add(3, "Susan", "Susan")
itmX.SubItems(ListView1.ColumnHeaders("Address").SubItemIndex) = _
"800 Chicago Street"
itmX.SubItems(ListView1.ColumnHeaders("Phone").SubItemIndex) = _
"555-4537"
Set itmX= ListView1.ListItems.Add(4, "Tom", "Tom")
itmX.SubItems(ListView1.ColumnHeaders("Address").SubItemIndex) _
= "200 Ocean City"
itmX.SubItems(ListView1.ColumnHeaders("Phone").SubItemIndex) = _
"555-0348"
Please help,
