I need to do the following but it doesn't compile
if(typeof(listBox1.Items) == typeof(string)){
return;
}
typeof(listBox1.Items) doesn't work at all. My listBox has 2 types of items in them and I need to know what kind of item a user clicked on so I can use it for drag and drop

hi
what is the use of the typeof keyword , and how does it differ from the
GetType method. i found the GetType method useful but i fail to understand
the use of the typeof method.
i have tried out a very simple example which i made up myself.
Employee e = new Employee();
ContractEmp ec =new ContractEmp();
MessageBox.Show(typeof(Employee).ToString());

I am using Reflection.Emit to dynamically build a class. A method of the
class to be built requires a Parameter of type "Type". But I don't know how
to use Emit to pass a call of "typeof()" to the method.
The method could look like this:
public void myDynamicMethod(Type type){
//.....do something with the Type passed in.......
}

Ok, I have three classes (The example here is extremely simplified to
illustrate the problem) like this:
Public Class A
Public Sub DoSomething(ByVal myClass)
If TypeOf myClass IS A Then

' Never Enters here....

End If

I am guessing there is a simple solution but given a type T, how can I check
for nullability?
how can I accomplish the following?
bool nullable = typeof(int).IsNullable; // false
bool nullable = typeof(int?).IsNullable; // true
bool nullable = typeof(string).IsNullable; // true
Thanks for any help.

Using A2003. I've got an option group that has a number of check
boxes. I have coding to clear the option group if the user wishes to
cancel their choice. This coding also clears the rest of the controls
on the form. Snippet of the coding:

ElseIf TypeOf oCtrl Is CheckBox Then
oCtrl.Value = False

Hi,
Is there an equivalent typeof macro/method to determine the type of a
variable in runtime & most importantly that works well with most known
C compilers?
gcc compiler supports typeof() macro, but the same code is not getting
compiled in solaris forte compiler and in microsoft VS 2003 compiler. I
tried something like below:

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...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
