I have user controls named as userCtrlxx where xx is a two-digit number. I'm adding these controls dynamically based on certain strings that are also two-digit numbers parsed from strings. I've tried using CType and DirectCast but no lucks so far.
Has anyone done things like that? Any suggestions? Thank you in advance.
Sample codes:
...
Dim userCtrl As UserControl
'Adding based upon a certain 2-digit string
userCtrl = DirectCast("use rCtrl" & 2DigitString, UserControl)
Me.PanelBox.Con trols.Add(userC trl)
'Adding using hard-coded name of user control
userCtrl = New userCtrl20
Me.PanelBox.Con trols.Add(userC trl)
I'm using VB Express 2005 on WinXP.

Just set the ID property of your control to that string, then you will be able to search and find them.
userCtrl.ID = "userCtrl" & 2DigitString
Me.PanelBox.Con trols.Add(userC trl)

Thanks Plater for the response. However, I did not find an ID property for the User Control. Did you mean its tag?
Thanks.

If this is a windows application I think you would use "Name" oopsy.
Just change where I put "ID" to "Name"

Using the Name property would make sense. However, I will still need to instantiate it as a New type of user control as in my samples for the hard-coded method. Do you have any pointers how to accomplish that? Thanks
i.e.
This did not work
Dim tCtrl as UserControl
tCtrl.Name = "userCtrl" & 2DigitString
userCtrl = New tCtrl
Me.PanelBox.Con trols.Add(userC trl)
How about a way to get all user controls so that I can loop thru and find a matched one? Any ideas?

Ah. -
Dim tCtrl as UserControl
-
tCtrl = New UserControl()
-
tCtrl.Name = "userCtrl" & 2DigitString
-
Me.PanelBox.Controls.Add(tCtrl)
-
Unless you are trying to get the class name by string (which I am starting to think that you are) and not the object name.
There is something like "reflection " that you can use, although I am entirely clueless on that subject.

Already tried that after my response earlier but did not work. May have to learn about the reflection that you're talking about. Thanks

I created a control that derives from the System.Windows.Forms.Control

I then created an interface to which this new control must adhere, so that I
could require future controls to provide certain functionality.
In my form code, I'm not going to be sure of what types of controls the form
will be using until run-time. So, I created an array of controls, all cast
as Control. This all works fine, so far.
Now, in the form code,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
