Hi all...
I am creating a small web-browser.I have almost completed my program.The remaining part is that when someone click on "bookmark" menustrip,it will store the url to a file (called as something.dat) and dynamically create a new menustrip of that url below "bookmark" menustrip (as same done with Internet Explorer "Add to Favourite" feature). Now anyone can access that url by clicking its menustrip item.
Please suggest me how can I do this.
Thanks.
Gagan

You add menuitems the same way you add controls to a form. You create an instance of the ToolStripMenuItem, set it's properties, wire up it's events, then add it to the Items collection of the parent you want it to show up under.
Dim newMenuItem As New ToolStripMenuItem
newMenuItem.Size = New Size(152, 22)
newMenuItem.Text = "Some &Menu Item"
AddHandler newMenuItem.Click, AddressOf MyMenuItemHandler
FileToolStripMenuItem.Items.Add( newMenuItem )

I have a need to write code similar to the following:
Private Sub Block()
Call Sub A(sender, e)
Call Sub B(sender, e)
Call Sub C(sender, e)
End Sub
where Subs A, B, & C have differing arguments.
Is this possible? If not, is there any way to do this?
I can supply specific code if necessary, but it can get
rather lengthy...
I appreciate any help.

Hi,
pass the arguments to the containing sub, something along these lines (details may be wrong,
normally I don't write VB):
Private Sub Block(arg1 as type1, arg2 as type2)
Call Sub A(arg1, arg2)
Call Sub B(arg1, arg2)
Call Sub C(arg1, arg2)
End Sub

Working with Active Directory in VB.NET
By Psycho-*Coder*-Extreme

Would like to know how this could be modified if possible to allow endusers to reset their own password when it has expired.
Allow for a questions/answer and maybe the last 4 of SSN. but allowing the user to reset password without providing to much security access to do so.
Is there already a VB.net ap or code that can do this?
Thanks

Here's a dumb observation. If the password has expired, they either won't be able to login, or they'll be forced to change the password upon login, without using any of your code.

I am calling a subroutine that starts with the following line:
Private Sub AddPayrollTable(ByVal TableCode As Integer, ByRef PayrollArray As String)
When this subroutine gets called I get an error that says "Object reference not set to an instance of an object."
This has lead me to believe that the array (PayrollArray) has not been initialized so I ask, how can I initialize an array that is a parameter in a subroutine?
Side note: When I reference the array directly in the AddPayrollTable subroutine instead of passing it as a parameter, I get no error.
Thanks,
Craig

Well, I see a couple of problems. The first parameter is passed as an Integer with the name "*Code". This leads me to believe it should be an enum, but I'm saying this based on very limited information. Right now, you're passing a "magic number" that offers no documention about what it means.
The second parameter is not being passed an array, but as a single String. Initializing an array is really mean to be done by the caller, not the callee. But, again, you haven't provided any information as to what this method does with the array and what the contents of the array is supposed to be, so it's difficult to say what the correct solution is.

Hi,
assuming your code compiles fine and produces a run-time error "Object reference not set ..."
when it somewhere calls your sub AddPayrollTable(...) that really means the caller hasn't
allocated the object (string?) that is being passed as the second parameter.
Yes, it is the caller that needs to initialize the parameters it is passing to the callee;
the callee can only accept them any way they come.
BTW: the name implies it would be an array, but then it should say As String()

Yes, I see now what the problem was thanks to Dave and Luc. I was calling the sub and passing an array to a string slot. Luc is correct, it should have said String(). Whoops. Thank you!

Unless you want to replace the entire array with another array, you should not send the parameter by reference. You can still change the items in the array when sending the parameter by value:
Private Sub AddPayrollTable(ByVal TableCode As Integer, ByVal PayrollArray As String())
However, you still have to create the array before calling the method.
If you want to create the array in the method, you should return the array from it:
Private Function GetPayrollTable(ByVal TableCode As Integer) As String()
If you want to add items to the collecion, it should be a list instead of an array:
Private Sub AddPayrollTable(ByVal TableCode As Integer, ByVal PayrollList As List(Of String))
Despite everything, the person most likely to be fooling you next is yourself.

How check for framework version

You can write some bad code and browse to that page. The bottom of the error message will state the version of .NET that's in use.
For example[^]
Good luck.

I'm assuming he's talking about find out which version the app is running under in his own code, not by crapping out an app and looking at the wreckage.

Hi, I'm trying to create one FTP automation using vb.net. Which is consist of the following requirement.
1) Downloading file (with specific file name)
2) Move the file at the FTP server to another directory
3) Uploading file
-All of the task need to be schedule at specific time and it's on daily basis.
Can someone help me on this matter.
|

You can start with the System.Net.FtpWebRequest[^] class to download files and rename them upload them. It exposes a basic FTP client in a class.
You'd probably write this as a Console application and schedule it to run using the Windows Scheduler
(Control Panel -> Scheduled Tasks).

I have implemented the IOleCommandTarget interface in a VB.NET 2005 Browser Helper Object. First, I wanted to share the code with everyone since it took me a while to get it working and I couldn't find any examples on the 'Net.
Now I want to be sure I know what to do with my new found toy. Specifically:
Do I need to output something from the Exec sub?
What do I output from the QueryStatus sub to answer Internet Explorer's interrogation?
Thanks! Here's the code:
Imports System
Imports System.Runtime.InteropServices
Namespace MyPopUpBHO
#Region "Interface Definition"

Public cwBuf As UInt32
Public rgwz As Char
End Structure
<structlayout(layoutkind.sequential)> _
Public Structure OLECMD
Public cmdID As UInt32
Public cmdf As UInt32
End Structure
' Interop definition for IOleCommandTarget.
<comimport(),> InterfaceType(ComInterfaceType.InterfaceIsIUnknown)> _
Public Interface IOleCommandTarget
Sub QueryStatus( _
ByRef pguidCmdGroup As Guid, _
ByVal cCmds As UInt32, _
<marshalas(unmanagedtype.lparray,> ByVal prgCmds() As OLECMD, _
ByRef pCmdText As OLECMDTEXT)
Sub Exec( _
ByRef pguidCmdGroup As Guid, _
ByVal nCmdId As Integer, _
ByVal nCmdExecOpt As Integer, _
ByRef pvaIn As IntPtr, _
<marshalas(unmanagedtype.sysint)> ByRef pvaOut As IntPtr)
End Interface
#End Regino
<guidattribute("b722bccb-4e68-101b-a2bc-00aa00404770")> _
Public Class ctvb
Implements IOleCommandTarget
Public Sub Exec( _
ByRef pguidCmdGroup As Guid, _
ByVal nCmdId As Integer, _
ByVal nCmdExecOpt As Integer, _
ByRef pvaIn As IntPtr, _
<marshalas(unmanagedtype.sysint)> ByRef pvaOut As IntPtr) Implements IOleCommandTarget.Exec
System.Windows.Forms.MessageBox.Show("Hiya Exec!")
End Sub
Public Sub QueryStatus(ByRef pguidCmdGroup As Guid, _
ByVal cCmds As UInt32, _
<marshalas(unmanagedtype.lparray,> ByVal prgCmds() As OLECMD, _
ByRef pCmdText As OLECMDTEXT) Implements IOleCommandTarget.QueryStatus
System.Windows.Forms.MessageBox.Show("Hiya QueryStatus!")
End Sub
End Class
End Namespace

This is the command that your code has to interpret and execute. Remember, your supplying the implementation of an interface that OLE is calling you with. This caommand can be executed in a seperate thread that your code sets up and starts. Any return value should be one of thoses documented here[^].
David Seger wrote: What do I output from the QueryStatus sub to answer Internet Explorer's interrogation?
This is normally filling in the status of the various commands you got in the Exec implementation. If your commands are still running, you update the status of those commands in the structures passed in from IE.

How do you format the date time to just date?
for example, this is what i retrievedd from the database: 12/31/2008 12:00:00 AM, but i just want to show the date and no time.

Hi Muhammad;
This will display the date only
' Simulate date and time from the DB
Dim dt As DateTime = Now
' This will display the date only
MessageBox.Show(dt.ToString("MM/dd/yyyy"))
