You really can't. Why are you still using VB6 ?

You can't without merging the code together and making necessary changes. Why VB6? It is a dead language now.

If you're thinking of doing this, you don't need to do it. This is a situation where you'd use an overloaded method.

Select Case won't do this. You have to get the types BEFORE using them in the Select Case statements.

Just letting you know that select case can do it.
Select Case True
Case Me Is Nothing
Stop
Case IsNothing(Me)
Stop
Case TypeOf (Me) Is Form
Stop
End Select
|
|
|
|

I know it'll work. He just needs to rewrite his Case statements. I also hate getting the TypeOf over and over again until it finds the correct Case. I get it once, before the Select, then use then returned type in the rest of the code.

sorry - misunderstood your statement 'Select Case won't do this'.
question on a different subject. each control has an event "enabledchanged" is there a way to make this fire even if you give it the same value? Enabled=true / Enabled=true? Is there any other technique that can be done that doesn't envolve creating my own control wrapper to detect this?
Thanks for your time.

No, it'll fire whenever the value actually changes.
nlarson11 wrote: Is there any other technique that can be done that doesn't envolve creating my own control wrapper to detect this?
Nope. You have to replace the Enabled property's Set method of the controls to get this to work. As it stands now, the Enable property code is this:
<DispId(-514), Localizable(True), SRCategory("CatBehavior"), SRDescription("ControlEnabledDescr")> _
Public Property Enabled As Boolean
Get
If Not Me.GetState(4) Then
Return False
End If
Return ((Me.ParentInternal Is Nothing) OrElse Me.ParentInternal.Enabled)
End Get
Set(ByVal value As Boolean)
Dim enabled As Boolean = Me.Enabled
Me.SetState(4, value)
If (enabled <> value) Then
If Not value Then
Me.SelectNextIfFocused
End If
Me.OnEnabledChanged(EventArgs.Empty)
End If
End Set
End Property
See the bolded If statement?? That's why the event won't fire if the value doesn't actually change. If the internal enabled variable is the same as the value passed in, the OnEnabledChanged method is never called, which is what raises the event.
Actually, the more I think about this, I'd ADD A NEW EVENT, possibly called EnabledSet, and raise it from the Set code in the Enabled property. I would NOT change the behavior of the existing EnabledChanged event.

For a tableAdapter , vb.net usually create automatically the fill() function .But i want to create a fill(parameter1) function where parameter1 is a value that filter data (by a filed ) filled into dataset.How can i do this ?
Thank you !

You'd have to write your own method to do this. Although, you would normally call the method something like "GetSomethingBySomeValue", not Fill(value). Make the name of the method meaningful. The concept is called "self documenting code". The name of the method should tell you what it does.
You can use the designer to help you do this by right-clicking the table you want in the dataset designer, and clicking Add Query...

Hi
I am quite new to this and have made a web project written in vb. Now i want to make a installer for this program and have created a web setup project and a custom action for that project. The thing is that during the install ui i want to run som code when the "next button" is pushed during one of the dialogs. How do i do this?
Confused

The custom action needs to run an exe with your code in it, you can't inject code into an MSI.

Cant you run for example Orca to customize a button and make it call a external dll or in some other way make it run som code that way? What i need is when a user enters the database name that he wants to use with the web project the program should check if the db already exists before he continues so that he can change the name.

Your con is fine, it is the ADOXCat that is not instantiated!

1 - they all are, to one degree or another. XVid and DivX are good, but so is MPG.
2 - by using DirectX

You can't add a datetimepicker to a textbox. You can't add any controls to a textbox, unless you are using WPF
