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.

Hi
Is there any controls in VB.Net similar to File upload control in ASP.Net
Regards
Sivan.G
|
|
|
|
|
There's an OpenFileDialog, but there's nothing to upload a file. The File upload control in ASP.NEt is just a wrapper around an HTML input control. The difference is, your browser already is sending data to a client, so it's easy to send a file. There are classes to do this in Vb.NET, but you need to set up your own network connection to send the data over.

hi,
I need to open,process,close multiple file streams (dynamic, i don't know how many will it be)
I have a array() as fileStream
And I have filled that array with fileStream, that I can do. but how to access each and every one of the files and do some work on it. And then close all fileStreams in that array.
I have figured it out only how to create them. Using this code
For i = 0 To numOfFiles - 1
stream = New FileStream(fileListing(i), FileMode.Open, FileAccess.ReadWrite) ' FileListing is a string array containing paths of the files
file(i) = stream
Next
Thank you!!

This isn't the way I'd do it, but all you have to do is access the methods and properties like this:
file(index).Read
If it were me, I'd probably wrap this file functionality in a class designed to work how you want it. The class would open the file, do any operations you want on it, and then manage closing the file when done.

You want a control to give you buttons that say bold, italic, etc ? How are you rendering this text ? Or are you hoping to use Word as a text box over and over in your project ?
A rich text box supports these things, but not buttons, you have to add those.
