What do you mean by form ? Form defined in your app ? Another app altogether ? A specific form in another app altogether ?

Hi,
if you hide and show forms, you must have a reference to it, so look at myForm.Visible

I am currently developing a VB 6.0 application. I also happen to have another VB 6.0 application already complete which I want users to be able to select at log on. How can I join these two applications without changing much of the code of the complete application? The two applications happen to share the same names for a number of objects. Please help.

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.

parameter,
but i want to get the type of this object at runtime using reflection and using select case but i am unable to do that , if else work fine but i want select case , thanks

'it works fine'
If t.GetType Is GetType(ExpenceVoucher) Then
Insert_ExpemseClaim(exp)
End If
'the following code gives compile time error'
Select Case exp
Case exp.GetType Is GetType(ExpenceVoucher)
End Select

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.

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.
