[Q] How can you see if you can add text to a control?

TheMSsForum.com: The Microsoft Software Forum

Hi!

Taking a randomly focused control on a form, how can you check to see if it
is a text-input control? I.e. a control that accepts input from the user.
What I want to do is add a text character to the control, but only if it can
hold text. For example if a button is focused, adding the char to this
controls Text-property would change the name of the button, which I don't
want...

1. What controls are "text-input" controls in CF?
Textbox, Combobox, NumericUpDown?, DomainUpDown?, more?

2. How can you determin if a control is of this type?
It must be done in the framework somewhere since typing a character in the
SIP when a button is focused won't change it's name, while doing the same
when a textbox is focused will add the character to the text...

3. Would it be the same in the full framework?

Off my head in VB.Net I'd do something like this

dim oControl as Control
for each oControl in me.Controls
if oControl is TypeOf(TextBox) then
'Do Textbox stuff
elseif -----
'and so on and so forth
end if
next

Should work....

But I think it'll take some work to get the currently focused control of a
form. =P

Hi Marauderz!

Thanks for your help and ideas. The equivalent in C# is:
using System.Windows.Forms;

if( sender is TextBox || sender is ComboBox )
{
// bla bla
}

regards,

Peter
