Hi,
I have the following line inside one of my class member functions:
static bool tested = false;
if (!tested) {
MessageBox(NULL , "Hi", "Testing", MB_OK |
MB_ICONEXCLAMAT ION);
tested = true;
}
The idea, of course, is to have this message box only pop up the first
time the member function is called. However, it doesn't work: the
message box pops up everytime. I know using static inside a normal
function causes the variable to persist. Is there some reason it
won't work inside a member function? Any way I can get it to work?
Thanks for any help,

Strange, this looks like it should work fine. There's nothing special about
statics in member functions vs. other functions. See if this works for you;
it should only put up the "dialog box" once:
#include <iostream>
using namespace std;
void stat_test()
{
static bool tested = false;
if (!tested) {
cout << "Displaying dialog box!" << endl;
tested = true;
}
}
int main()
{
stat_test();
stat_test();
stat_test();
return 0;
}
HTH,
-leor Thanks for any help, cpp

Leo,
It was the message box screwing things up. If I do:
static bool tested = false;
if (!tested) {
tested = true;
MessageBox(NULL , "Hi", "Testing", MB_OK |
MB_ICONEXCLAMAT ION);
}
it works fine.
Thanks,

Dear Newsgroup,
I'm somehow confused with the usage of the static keyword.
I can see two function of the keyword static in conjunction with a data
member of a class.
1. The data member reffers in all objects of this class to the same data
Or in other word by using the static keyword all objects of one class
can share data. (This is what I want)

Why is the static variable inside a member function static for all instances

I have noticed that C programmers put static keyword beside global
variable and global functions in C source codes. I believe that it is not
necessary and it is not the practice in C++. Static keyword is useful
inside struct, class, and function only unless you want to force local
variable to be global variable so static is used.
Do you have idea why most programmers do this?

There are two typical implementations of a singleton. The first one
is
to use a static pointer
class Singleton {

return pSingleton;

Hello,
I learned that there are five kinds of static objects, namely
1. global objects
2. object defined in namespace scope
3. object declared static instead classes
4. objects declared static inside functions (i.e. local static
objects)
5. objects declared at file scope.

Traits is a useful template technique to simplfy the implementation of some

Following is an example of traits template with specializations (copied

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

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,...
