I need help with code.
The app I'm building I have a combo box for drive letters
I want the combo box to only have the cd/dvd drives listed instead of having A-Z
also when i change the selection I want it to display disc volume label and capacity to 2 separate text boxes.
The rest of app is in 1.1 so I'm looking for a 1.1 solution.
Please help me out.

What you're looking for comes from WMI and the Win32_LogicalDisk[^] class. All you need is the Windows Management Instrumentation classes in the .NET Framework under the System.Management[^] namespace.

Well that page is talking about windows script.
and not sure how I can convert it to .net 1.1
|
|
|
|
|
No, that page is talking about a WMI class. The example on it is in VBScript.
The second link is about using WMI in the .NET Framework.

Hehe I figured it probably was. So I thought I'd use the chance to post something using big red letters (been wanting to do that for awhile.. just to be silly..) when I wouldn't actually insult someone asking a real question

i am working in a VB Access application where a Business Object is used.
whenever i launch the appllication it gives me error on Business Object.
Is it that i dont have the Busines Object in my machine?
How does it actually works?
Do i need to download the business object from somewhere?

You're going to have to explain this a bit more to get an answer. What's a "Business Object"?? Is this a VB6 or VB.NET app with an Access database as a backend?? Or is this an app written in Access with VBA code??
nicetohaveyou wrote: whenever i launch the appllication it gives me error on Business Object.
Standard question #1: "What is the error message"?

You haven't told us what "Business Object" is, so how can we tell you how it works?? Got a link to this library or control you're using?? Searching for "Business Object" is a little pointless considering how generic the name is.

i have tried to use 3 layers
Presentation Layer,business Logic Layer, Data Access Layer
Just i Have tried,tell whether this is correct or not?
In My Presentation Layer
i have two textbox one for UserName and other for password
Private Sub btnSubmit_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.ServerClick
Try
Dim cus As New UserBLL
cus.UserName = txtuser.Value.ToString
cus.UserPass = txtPass.Value.ToString
cus.Verify()
Catch ex As Exception
Response.Write(ex.Message.ToString())
End Try
End Sub
In My business Logic Layer
Public Property UserName()
Get
Return user
End Get
Set(ByVal Value)
Try
Me.user = Value
If (Me.user = "") Then
Throw New Exception("Please Provide The User Name")
End If
Catch ex As Exception
Throw New Exception(ex.Message.ToString)
End Try
End Set
End Property
Public Property UserPass()
Get
Return pass
End Get
Set(ByVal Value)
Try
Me.pass = Value
If (Me.pass = "") Then
Throw New Exception("Please Provide The Pasword")
End If
Catch ex As Exception
Throw New Exception(ex.Message.ToString)
End Try
End Set
End Property
Public Sub Verify()
strReturnfromDAL = UsrData.Verify2("user", "pass")
End Sub
In Data Access Layer i Have
Public Function Verify2(ByVal str As String, ByVal str2 As String) As String
If str = "user" And str2 = "pass" Then
Return str + "" + str2
End If
End Function
In above i have tried to get a concept but i think i am not in correct way and
i need a result like verfying the user name and password and return back to BLL
i am not getting any error but i am not able to get the value of verify function to prsentation layer.

You obviously don't have a data layer here at all.
Your 'business layer' is using exceptions to pass information that should exist in the presentation layer.
You plainly don't need to call ToString on a Text property, it's a strng already
Having the username and password as members makes no sense at all, you want to pass them in and get a result, you don't want to store them

What is this in aid of ? Make sure you catch the only exception that can be thrown, and rethrow it ?
This is all a mess, throw it away and start again. Get a database and write a proc which returns true is a username/password combination is valid. Return true or false from the BL, whch just calls the proc. Do all your rendering/generating of messages in the PL

Hi experts,
I m basically fighting wid a prb for writing data in a physically opened excel file. Is it possible to write in cells of the excel which is physically open ?
If so, pls guide me how can i implement it ?
Thanks.

No, it's not. You have two problems. First, the file is already open, so any changes you make will be destroyed when Excel save the file.
Second, the Excel file format is binary and VERY complex, up to Excel 2003. You cannot just open a file for binary access, write to it, and call it a cell in Excel.
In Excel 2007, the file format changed to an open-spec XML format, which is basically a text file. But, you still can't write to a file opened as ShareDeny by another application.
