MsgBox ("No Data")

The DB structure is simple.. with PKey as a auto number, ExpName as a text. Thats it...
Any idea of my error....

Try using the Execute method of the dataabse object instead of the OpenRecordset method.
db.Execute(SQLString)

I can pass an ArrayList of myClassObjects to a DataGrid and it obligingly displays it but it shows all of the Columns at the default Width including the ID Column. It also labels the Columns with myVariable names.
myDataGrid.DataSource = myClass.myFunction
Where myFunction is returning an ArrayList of MyClassObjects.
I have tried using a DataGrid Table Style Object etc. to no avail. How can I hit those pesky Column Objects directly to set their Widths and Headings?

Hi...
I am a beginer to VB.. and a basic question....
Any code or snippet for accessing MS access database from VB, on a button click action... I tried this....
Private Sub Command1_Click()
Dim DBCon As ADODB.Connection
Dim rsTemp As ADODB.Recordset
Dim objMail
Set DBCon = New ADODB.Connection
Set rsTemp = New ADODB.Recordset
On Error GoTo errhandle
DBCon.Open dsn.Text, username.Text, password.Text
rsTemp.CursorLocation = adUseClient
rsTemp.Open SQLstr.Text, DBCon, adOpenForwardOnly, adLockReadOnly
mailbody = body.Text
For i = 1 To CInt(paramnum.Text)
mailbody = Replace(mailbody, "[x" & i & "]", rsTemp.Fields("x" & i))
Next i
MsgBox "From = " & from_txt.Text & Chr(10) & Chr(13) & _
"To = " & rsTemp("toemail") & Chr(10) & Chr(13) & _
"Subject = " & subjfield.Text & Chr(10) & Chr(13) & _
"Body =" & mailbody
Exit Sub
errhandle:
MsgBox Err.Description
End Sub
But it says....
Compile Error, User defined type not defined in the very first line of the code. Should I make/modify any configurations??
Thanks

I am trying to watch for "n" number of folders. Do I have to create "n" number of FileSystemWatcher instance to do this? If anybody worked on this please advice. Thanks a lot.

Is more easy create one folder and five subfolders. You only watch for the parent folder or root folder and FilSystemWatcher, with "true" in watch subdirectories option, watch the six folders.

Thanks for your reply. But folders can't be sub folder in my project. Anyway i have figured out the solution. Here is the code if anybody is interested.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim i As Integer
Dim strName As String
Dim strDBReject As String
Dim strParseReject As String
'Load the profile info from the setup XML file
Dim dsGetIni As New DataSet()
dsGetIni.ReadXml(Application.StartupPath & "\setup.xml")
Dim dtGetIni As DataTable = dsGetIni.Tables("Profile")
i = dtGetIni.Rows.Count
Dim objRow As DataRow()
For i = 0 To dsGetIni.Tables("Profile").Rows.Count - 1
strName = dtGetIni.Rows(i)("Name")
strDBReject = dtGetIni.Rows(i)("DBReject")
watcher(strDBReject)
strParseReject = dtGetIni.Rows(i)("ParseReject")
watcher(strParseReject)
Next
End Sub
Public Function watcher(ByVal strFolder As String)
Dim objWatcher As New System.IO.FileSystemWatcher()
'Folder to watch
objWatcher.Path = strFolder
'File extension to watch
objWatcher.Filter = "*.pdf"
'Create delegates to handle the events for the FileSystemWatcher
AddHandler objWatcher.Created, AddressOf OnFileCreated
'Exclude subdirectories from watching
objWatcher.IncludeSubdirectories = True
'Start watching folder
objWatcher.EnableRaisingEvents = True
End Function
Public Sub OnFileCreated(ByVal source As Object, ByVal e As System.IO.FileSystemEventArgs)
Try
'create new instance of importer
Dim FileInfo As New FileInformation(e.FullPath)
ThreadPool.QueueUserWorkItem(New WaitCallback(AddressOf ProcessFile), FileInfo)
Catch ex As Exception
End Try
End Sub
Private Function GetExclusiveAccess(ByVal FilePath As String) As Boolean
Try
Dim theFile As File
Dim strm As Stream = theFile.Open(FilePath, FileMode.Open)
'if we succeed, we can let it go
strm.Close()
GetExclusiveAccess = True
Catch e As Exception
GetExclusiveAccess = False
End Try
End Function
Public Sub ProcessFile(ByVal fileInfo As Object)
If Thread.CurrentThread.Name = "" Then
Thread.CurrentThread.Name = Thread.CurrentThread.GetHashCode().ToString
End If
'try to get exclusive access to the file first
Dim i As Integer
For i = 0 To 30
If GetExclusiveAccess(fileInfo.filepath) Then
Exit For
ElseIf i = 30 Then
Exit Sub
End If
Thread.Sleep(5000)
Next
Dim strFilePath As String
Dim strFileName As String
Dim strDirName As String
Dim strVendorName As String
Dim strReason As String
Dim x As Integer
Dim y As Integer
strFilePath = fileInfo.filepath
strFileName = Mid(strFilePath, InStrRev(strFilePath, "\") + 1, Len (strFilePath) - InStrRev(strFilePath, "\"))
MsgBox(strFilePath)
'Add Reject file info to the database
addtodb(strFileName, strVendorName, strFilePath, strReason)
End Sub
If anybody is interested try this code. Let me know if you have any questions. Thanks

Hi...
How do Change the location of, for example a textbox? I Know u Can do it when you place the textbox. But if you wat to do it during runtime, how do u do it?
Code used:
TextBox1.Location.X = 10
Error message:
Expression is a value and therefore cannot be the target of an assignment.

Hello Everybody,
I am developing a Module in which I suppose to use Web Browser control which acts as Windows Explorer. I am tried most of the functionality with SendMessage API with different parameters like IDM_SHVIEW_LARGEICON, IDM_SHVIEW_SELECTALL etc. 
But now I want to create a New Folder in the exact way Windows Explorer allows user. For consideration, let's say we will click a button & New Folder functionality should work. All the mention parameters are working with SendMessage API except IDM_SHVIEW_NEWFOLDER. 
'Declaration
Private Const IDM_SHVIEW_NEWFOLDER = &H7261
'In command button
SendMessage(hwndSHView, WM_COMMAND, IDM_SHVIEW_NEWFOLDER, 0)
' hwndSH = handle of the SysTreeView32
' WM_COMMAND = message
' IDM_SHVIEW_NEWFOLDER = lParam for action to be performed
' 0 = wParam
I cross check the window's handle value. Still not getting the result. Also assigned handle the default value (which I got from SPY++).
Please please please help me out from this problem. 
Regards,
Vilas

do you have access to SQL Server or MSDE ??
if yes try this in a stored procedure..
declare @command varchar(1000)
-- delete a file on the C drive
SELECT @command = 'del C:\Test.txt'
-- execute DOS command
master.dbo.xp_cmdshell @command
that should do it

Thanks! Good functions!
Basically I wanted to know how to "Left / Right Shift" a number but the above functions will also come in handy. I will Post here how to do Shifts.
To Right Shift, simply Divide by (2 ^ [No of Bits]). For example, to Right Shift 16Bits:
Public Function ShiftRight(ByVal Value as Long) As Long
Return (Value / (2 ^ 16))
End Function
To Left Shift, simply do the opposite and Multiply by (2 ^ [No of Bits]).
Public Function ShiftLeft(ByVal Value as Long) As Long
Return (Value * (2 ^ 16))
End Function
The good news is that in VB.NET 2003, the Left / Right Shift operators will become standard. So now the above Functions would be simplified like this:
Public Function ShiftLeft(ByVal Value as Long) As Long
Return (Value << 16)
End Function
Of course, you really wouldn't need a Function for it anymore in .NET 2003!

I know MS (FINALLY) added in lazy evaluation versions of And (AndAlso) and Or (OrElse). Have they perchance introduced a lazy eval version of the ternary-operator function (Iif)?
Thats one thing i sorely miss from the C/Java world is the nice ?: operator. Iif can sort of emulate it, but Iif always evaluates both conditions (true AND false)... where as the ?: one only evaluates which ever one is selected by the condition. The Non-Lazy Iif is all but useless for the most very simplest simplest basic cases.
Thanks in advance
