I have developed a custom control to be used in my application. My
application includes a form designer, so the control can be hosted while
designmode for the control is either true or false, depending on whether they
are using the form designer, or in "run mode". The custom control includes a
slider control that is supposed to be active in our form designer
(designmode=true) and inactive in our run mode (designmode=false). The

I have made a custom control that draws a rectangle when the mouse is down, and does nothing when the mouse is up.
I set/reset a flag in MouseDown/Mouse up and use this to do the drawing in the OnPaint .
The recangle draws correct when i press the mouse, but when i release the mouse the background is not restored
What should i do in the Onpaint to make sure the background (the form) is restored correctly ?
This problem already keeps...

Please, help.
I created my contol, ButtonX, which subclasses System.Forms.Windows.Button
class. I am doing my own paiting, by overriding OnPaint and
OnPaintBackground (without calling base class's OnPaint &
OnPaintBackground). My button has a shape of rectangle with rounded corners
and is filled with gradient brush, where user specifies the gradient colors.
The dilema I have now is how to paint the button when it's disabled (Enabled

I have create a Panel subclass that I can resize at runtime. I want to
draw resizing handles that accurately track the panel frame.
So far I have tried drawing them in the wm_sizing handler, the wm_paint
handler and the overriden OnPaint event and cannot get an accurate
rectangle to use to paint the handles. The handles sort of follow the
border but not exactly. It seems that it might work to do it at the same
time the border is drawn with...

In VB .Net I made a custom CheckBox column style (for the Datagrid control) that maps to two DataTable columns , one it uses for the Checked status and the other it uses for the Enabled status. I am having a couple problems so far.

Hello
i have made a custom control. i have placed a panel on it. I want this
panel to behave just like the normal panel. The problem i was having is
that the panel on my custom control doesnt accept other controls. The
control i drag drop on it becomes the child of my custom control's
parent form and not the child of my custom control. Then i added this
line
""
before my custom control class (i dont know what this line does). Now

I have a compound custom control derived from UserControl. It has three controls on it -- two
custom controls and a Label control. When the control is added to a from and then resized using the
Designer how do I trap the resize event so I can resize the child controls?
I have tried the using:
protected override void OnSizeChanged(EventArgs e)
But it doesn't get called when the control is resized in the Designer.

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I'm a network technician in training and I need your help.
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.
