The easiest way to do it would be to copy the items, one at a time, from one combobox to the other.
Dim index As Integer
ComboBox2.Items.Clear()
For Index = 0 To ComboBox1.Items.Count() - 1
ComboBox2.Items.Add( ComboBox1.Items(Index) )
Next
Or you could bind the Items collection of one Combobox to the other.
ComboBox2.DataBindings.Add(New _
Binding("Items", ComboBox1.Items, "")

Try using the CopyTo method of the first combobox to copy its contents to an array then use the AddRange method of the second combobox to copy the array.

There is no other method in VB6

You didn't say you were using VB6 before. Is there some reason you can't fill both ComboBoxes at the same time? That way, you're only enumerating the data once. Otherwise, you have to enumerate the data again, either from the datasource or from the first ComboBox, to fill the second ComboBox. You could still try databinding, but it's a bit more complex than the .NET version. Try this[^] for an example in VB6.

Is there a term or practice of running an application on a web server? I would like to run a program either console application to send commands to my ASP.net application on shared hosting. Some commands would drop tables, delete expired records, and update table data.
Should I use a web service or windows service to perform these tasks or is there another method for employing these executions? Is it possible to write something like this and have it running as a background service?
Also, I would like it to run it as a process with at any time an option to disable the process. Consider the term "web application sub-worker."
Any help or comment about this would be greatly appreciated. Thank you.

These are things you do with SQL commands. You could do it with the SQL Query Analyzer. It would bypass your ASP.NET site completely. If you wanted to, you could create a WebService that takes commands you type in SQL and forwards them to the SQL database, but that would represent a huge security risk.
Are you talking about an AUTOMATED method of running these commands on a schedule? In that case, SQL Server has it's own scheduler service for running batch commands like this on a schedule. All it would take is putting these commands into a stored procedure, the setting up the scheduler to run it.
If you running your site on a shared host, I don't think the owner's will let you install a background process on their servers.

Hi everbody
iam using an application in which iam using an exe audioplayer called big hand which will play only
text messages.i have a rich text box in my form what i have to do is i have to type all the text
messages that are played by this big hand player.when ever i run this big hand player it is showing some common dialog box and asking what file should be opened.
my problem is how to capture the file name when iam opening the file and the same file name should be present when ever i save(for the first time)my text that i have typed in rich textbox in the common dialog box
and again is there any solution for keeping this exe file fixed into the file so that when ever i close the form that exe should also be closed automatically

You can't capture the filename from a Dialog that was opened by another application.

You can't embbed another .EXE into your own application. You can launch it as an external application using the Process class. You can then close that process when your application closes, in your Closing event handler, by calling .CloseMainWindow on the Process object that your got when you launched the external application (BigHand player).

 Hi,
The Registry key to get current user name is like below. What is the registry path to get current user login time??Any help?? Thanks~
Private Sub GetCurrentLoginName()
Dim reg As RegistryKey 'the reg key
Dim subKeyName As String 'key names
reg = Registry.Users
If Not reg Is Nothing Then 'check maybe keys does not exists
For Each subKeyName In reg.GetSubKeyNames
reg = Registry.Users.OpenSubKey(subKeyName & "\Software\Microsoft\Windows\CurrentVersion\Explorer", False) 'open the subkey
If Not reg Is Nothing Then 'check
If reg.GetValue("Logon User Name", Nothing) Is Nothing Then 'read
'no user found in this subkey
Else
loginName = "Login Name: " & CType(reg.GetValue("Logon User Name", Nothing), String)
End If
End If
Next
End If
reg.Close()
End Sub

Well, you have a few problems...
1) The last logon time is not stored in the registry.
2) The last logon time is not stored for local accounts, only for domain accounts and only on the domain controllers.
3) The last logon time is not replicated between domain controllers. You have to query the account information on each domain controller, then compare them to see which last logon time is the latest, then use that time as the last logon time.

I try to double click, but it doesn't show me the form i intended to show. How come the events doesn't work?
I set the visiblity of notify icon from the windows service to true, then check the "Allow interaction between desktop" in the Services (Control Panel). But the notify icon, still doesn't show the form when i click or double click...

In my mdi-container, I have an instance of magic's docking manager.... To this instance tools are added and docked to the left...
I also have a bunch of main munus displayed on top of my MDI-container.
Now, I have tried adding a toolbar to this dockingManager instance such that the toolbar appears on top of all the other docked items on the screen.
Well, after a lot of tries I gave up and I just decided to add the toolbar with a floating state and if the users want they can dock the toolbar to the wherever they want.
Now the question is, how do I get rid of that ugly blue caption of the toolbar. Before rushing into answering, I know I can set the caption to false, but that only gets rid of the title. I want the entire caption lines gone....
Hope some one can help
Cheers!

The toolbar becomes a Toolwindow. You can't get rid of the top caption bar, only, as you have found out, removing the caption text. The caption bar is required to keep the functionality of moving the tool window and having a place to put the little X (Close) box.

Im designing an application where the user priviledges to each menu option are stored in a database. So on form_load I read the values from the database and appropriately set mnuItem.enabled to true or false. Currently I am using a case statement similar to:
Private Sub EnableMenus (ByVal mnuName as string, ByVal blnEnabled as boolean)
Select case mnuName
Case "mnuAction1"
me.mnuAction1.enabled = blnEnabled
Case "mnuAction2"
me.mnuAction2.enabled = blnEnabled
etc
etc
End Select
End Sub
I would like to do something like:
Private Sub EnableMenus (ByVal mnuName as string, ByVal blnEnabled as boolean)
mnuMain.MenuItems.Item(mnuName).Enabled = blnEnabled 'however Item only accepts an Integer index value
End Sub
Any thoughts?

Are you just trying to enable a menu like after you click on a button, or are you trying to use it as a function to be Called by another procedure?
|
|
|
|
|
I am enabling / disabling menus on form load, and when a different user logs into the application. So, I am wanting this functionality in a callable subroutine.
I am thinking that there should be some meta data to achieve this in System.Reflection.Assembly, but I have not found it yet.

Are you going to use ASP for the login or are you going to generate a form that will test the condition of whether the username and password are correct?
|
|
|
|
|
Logins will be handled via a windows form.
|
|
|
|

OK if I understand you correctly. You would have to set up a control, maybe make it invisible, that test the preference of the user to decide whether to enable the menu or not. You can do that by making the values of the menus be conditions that must be tested before being done. I personally would use an access table with the username, password, and the conditions I wanted the user to have, as far as the menus are concerned. Then I would have a label with the username entered into it after a successful logon, and then i would have a select statement that would base the preferences, or menus, for the and I would use an if statement or case statement for testing the values of the condition to determine whether to enable the menu or not.
I hope that helps you some at least.

I'm not sure ccotton333 understood what you are asking, however here is another take on what you could do. Write a derived MenuItem class that inherits from MenuItem, have this perform validation against the WindowsIdentity or your own logic to specify access within the constructor, setting the enabled value appropriately. Thus, use your derived MenuItem class in place of the standard MenuItem. Does this make sense?
