The problem is the spaces, your right. But solution is also pretty easy. The problem comes because the spaces are seen as command-line argument seperators. This is the command-line your sending to Shell:
D:\...\wmplayer.exe g:\mp3\045- mp3\test.mp3
Your actually telling wmplayer that there are 2 command-line parameters:
'g:\mp3\045-' and 'mp3\test.mp3'
The solution is to put quotes around both parts of the command-line:
PlayFullName = chr$(34) & "G:\MP3\045- Mp3\test.mp3" & chr$(34)
stAppName = chr$(34) & "D:\Program Files\Windows Media Player\wmplayer.exe" & chr$(34) & " " & PlayFullName
Now your sending the command-line as:
"D:\...\wmplayer.exe" "G:\mp3\045- mp3\test.mp3"
The quotes will prevent the spaces from becoming argument seperators.

I am chaning default printer using WshNetwork. In my project there is a printer pool and machine is Win2k. My code works fine on my machine(XP). But when i try to change the printer on Win2K it doesn't work, if one of the printer is turned off on the printer pool.
Here is the code:
Dim WshNetwork = CreateObject("WScript.Network")
WshNetwork.SetDefaultPrinter(cbobwprinter.Text)
MsgBox("Success")
Catch ex As Exception
MsgBox(ex.ToString)
MsgBox("Can't set the default printer!", MsgBoxStyle.Critical)
Any idea why it won't work in Win2K! .Net framework is installed on Win2K box. Thanks

Hello coders,
You know in VB6 there were some apis like
CreateREctRgn
CreateEllipticRgn
...
Is there any equivalent in VB.NET of one of those?
How do I use them?
Thank you
Have a nice day
Best Regards

The following code can be used to change the shape of a control. It may give you some ideas about how to use regions:
Dim intDiameter As Integer = 200
Me.Height = intDiameter
Me.Width = intDiameter
Dim p As New Drawing2D.GraphicsPath()
p.AddEllipse(0, 0, intDiameter, intDiameter)
Me.Region = New Region(p)
Hope it helps
Regards

Thank you very much..
I have another problem.
How can I combine two or more RGNs?
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim intDiameter As Integer = 200
Me.Height = intDiameter
Me.Width = intDiameter
Dim p As New Drawing2D.GraphicsPath()
Dim r As New System.Drawing.Rectangle(0, 0, 80, 80)
p.AddRectangle(r)
p.AddEllipse(0, 0, intDiameter, intDiameter)
Me.Region = New Region(p)
End Sub
But there is a problem. It cuts off the region (which already created before)
There was an api called CombineRgn
in the api there was a mode that you can set the combining property
Best Regards

It's been divided into 5 methods:
Region.Complement
Region.Xor
Region.Union
Region.Exclude
Region.Intersect
So instead of:
Me.Region = New Region(p)
do:
Me.Region.Complement(p)

Hi....I have a datagrid that as the user finishes entering a row, a duplicate of the row will pop up. When the user saves (updates) sometimes the extra row is saved sometimes not. Very strange behavior. I found a post on another site where a developer expressed the same behavior and said that he "had to detach the grid prior to messing with the dataset". I don't understand what he means (I've asked him but haven't received a reply). Does anyone want to take a stab at what they thing this means and how you would detach a grid? Thanks in advance.
Thanks,
Mike

What was the error (exception) that you got back?
Can you show some code? The DB structure?

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??

Did you add Microsoft ActiveX Data Objects to your references? To do this, Click Project | References on the menu, and check the check box beside it in the dialog box.

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.
