How can I prevent a few lines of code contained in the constructor of a Form
from being executed by the Designer?
Thanks,

Fabio,
Check the DesignMode property of the control that you have. If it
returns true, then you are in design mode.
This is inherited from Component.
Hope this helps.

Fabio,
When developing user controls or custom controls, I SOMETIMES use
this.DesignMode to prevent things from being created.
Why do you need it for a form?

Check the DesignMode property of the form.
if (!this.DesignMo de)
{
// Code here only executes when running, not in design mode
}
-mdb
Thanks to all of you guys.
In reality I need this in an object inherited from UserControl, not from
Form.
The constructor of my UserControl will create some unmanaged objects using
interops, and I suspect this is what is causing lots of problems with my VS.
See my other post just two hours ago: "Bad UserControl in toolbox".

Since you are doing this work in a UserControl, you might find that you need
to move some of the code out of the constructor to get the DesignMode
property to function correctly: http://groups.google.com/groups?as_q...e+gone+in+.Net

This article mentions what u said: http://msdn.microsoft.com/library/de...edebugging.asp
Any class that derives from the Component class has a property called
DesignMode that is set to true when the code is executing within the
constructs of the Visual Studio .NET designer. So you have the option to
wrap code within an if statement. There's one more trick, however. The
DesignMode property isn't set to true in the constructor. Remember, there's
no real magic here. Visual Studio .NET creates your object as it parses the
InitializeCompo nent() method. Once the object is constructed, Visual Studio
..NET keeps track of the objects it creates.....
Microsoft needs to update the documentation for Component.Desig nMode
Property: http://msdn.microsoft.com/library/de...nmodetopic.asp
to reflect this information!!!

Sometimes (but not always) the __new__ method of one of my classes
returns an *existing* instance of the class. However, when it does
that, the __init__ method of the existing instance is called

example, please consider the following class (a singleton in this case):

In browsers which utilise a JIT JavaScript compiler, are there any factors
that may prevent a script from being compiled before it is executed? I
don't see any reason why this would be so but I would like to check that
scripts that access Java classes & methods and/or scripts which are loaded
dynamically using AJAX will both be valid candidates for jittering.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
