can anyone tell me why I cannot pass values in a setTimeout function
whenever I use this function it says "menu is undefined" after th
alert.
function imgOff(menu, num) {
if (document.images) {
document.images.src = eval("mt" +menu+ ".src")
}
alert("imgOff_hidemenu");
hideMenu=setTimeout('Hide(menu,num)',500);

Hello,
in the last few days I've made my first few attempts at creating mixed C++
managed-unmanaged assemblies and looking aftwerwards with ILDASM at what is
visible in those assemblies from a managed point-of-view I've noticed that:
1) for each managed and unmanaged C function (not C++ classes) I get a
public managed static method (defined on a 'Global Functions' class) in the
generated assembly with an export name of the form...

According to what I have learnt so far, instantiating global objects should
be the last resort. Is there any reasons why so?
Sometimes some objects or their pointers have to be shared among several
other objects, I'd like to know how this is handled commonly. Could someone
elaborate on this?
Another situation is some objects could be shared among several threads.
How to handle it commonly?

This is a purely *hypothetical* question. That means, it's /pretend/,
CP. ;-)
If you were forced at gunpoint to put all your code in classes, rather than
in namespace scope (obviously classes themselves are an exception to this),
and 'bootstrap' your program by instantiating a single application object
in main(), would that place any limitations on what you could accomplish
with your program? Are there any benefits to doing things that...

Hi,
I am designing an application where to preserve the hierachy and for
code substitability, I need to pass an array of derived class object in
place of an array of base class object. Since I am using vector
class(STL), the compiler does not allow me to do this.
I do realize there is a pitfall in this approach(size of arrays not
matching etc), but I wonder how to get around this problem. I have a
class hierachy with abstract base...

Just spent a happy 10 mins trying to understand a function I wrote sometime
ago.
Then remembered that arguments are passed by reference, by default.
Does the fact that this slowed me down indicate:
a) That I don't know enough
b) Passing arguments by ref is bad

Hello All,
I've defined a number of classes that currently only include public variable
declarations. I've been reluctant to add subroutines and functions for fear
of taking a performance hit when I pass the class as an argument to another
function and in a one case, store the class to a session variable.
Right now I have all of my functions and subroutines in a single class
that's becoming a bit unwieldy. What I'd like to do is move...

Hello,
I'm currently developing a web service that retrieves data from an employee
table. I would like to send and retrieve a custom employee class to/from the
webservice. I have currently coded the custom employee class and have built
it as a separate library (employee.dll). This employee.dll is being
referenced by both the web service and the windows application.
I face the following problem when I send this class to the webservice.

Hi All,
In C++ we could pass a constant reference to a function so that the
target function could not modify the objects passed
eg. const classA & dummmyfunction(const classB)
similar thing was valid for objects passed with pointer to constant
objects
In C++/CLI is there any way for imitating this, I want to pass
arguments to and return value from my member function as a constant

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:

Overview:
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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
