hi:
i am developing a custom combobox for my company's needs that is made
up of a textbox, listbox, button. i am using c#. everything is fine
except for one issue.
in a normal combobox, when the dropdown is visible and the user clicks
anywhere else, the dropdown gets hidden. i am trying to replicate
this behavior and have tried using the Leave and LostFocus events. i
have had marginal success when my dropdown is visible and i...

I may have already asked this one, but,
Is there anyway of hiding the dropdown control button on a combobox until
the field has focus?
Because the values in the combobox can be between 5 charicters long and
thirty charicters long, this poses the problem that when a five charicter
string is selected, the button looks a mile away. I have the background of
the combobox set to transparent, but the button still appears

There is a form (single form) and a combobox. I want that current record of
the form is adjusted according to selected value in the combobox. Cuurrent
record should be the same as the value in the combobox.
What is the solution?
Thank you in advance.

Greetings.
I have a form (frmDogs) that is invisible while a subsequent form
(frmPeople) is visible. The visible form sets a value for a combobox
(cboOwner) in the hidden form, makes the invisible form visible and then
closes. When the newly visible form (frmDogs) appears the combo box
(cboOwner) is displaying the correct information (set from the previous
form). There is no indication that anything is wrong when I save the
Dog...

When you use a bound combobox and you set its dropdown style to "dropdown"
that allows you to enter text in the edit box. But if you enter anything
other than a value in the current bound items collection, the .text property
does not update. Furthermore, you can't easily trap an event to examine the
new value if your program assigns it programmatically as opposed to someone
typing it in and tabbing away from it. That is, TextChanged does...

I have a general DataGridComboBoxColumn that I built using the Example in
the .NET 2003 Combined Collection help file (that was a data time picker).
I am able to assign a data source and display / value members so the
ComboBox is data bound and that works, to a point. What generally works is
the ComboBox get's populated and the ComboBox shows itself when the
appropriate column/row is selected. When the ComboBoxColumn isn't selected

I've modified a combobox class so that it has a ReadOnly property.
When set to ReadOnly, the combobox can't be changed, but it doesn't
appear gray. I called the new class ComboLockBox and I've placed them
on a MDIChild form and they work great.
The problem is, I got a timer that looks for mouse activity and when
the mouse is idle for a set number of minutes, all MDIChild forms are
hidden and the Logon form is displayed.
When the user...

I have a ComboBox on my form, and I set it's DataSource to an ArrayList of
custom objects. Everything loads fine, all the entries I initially loaded
into the ArrayList appear in my ComboBox.
However, while my program is running and I add a new object to that
ArrayList - this ComboBox is not updating to reflect the change.
I have gone so far as to try:
clientList.Invalidate();

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.
Here is my compilation command:

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
