u should know what static means.

static makes a thing (function or varable) into real thing - or the thing is created in memory (an instance for var).

class is a concept or blueprint which can not be created in memory (its instance can).

Nope, but you can do like this:

static class X {
public :
int x;
} static_object_of_class_X; // The variable static_object_of_class_X will have static linkage.

writing a class means in defining the memory organisation of the type you are creating.

static class X { /*...*/ }; is as if you define a syte that is already static (which don't mean anything).

static means several things.
1st, static means that the life of the variable should be durind still the program is running. of course, its scope don't change, but the variable is not destroyed when the function it is in ends.
2nd, static means that the data member is defined once for all instances of an object.
3rd, static applied for function members means that the function may access only static data members.

You can also do the drawing by overiding the WM_NCPAINT handler.

#2 http://www.codeproject.com/property/hacking_the_cpropertyshee.asp[^] has code on accessing the buttons on the sheet.

Hey...

I have an MFC application where I have added the first recordset for the application.Now I face problem in adding second recordset for the MFC which means to create new class for retrieving the variables from other database table.I have tried to follow the MSDN links and tutorial on this but as I follow the steps,I faced problem in creating new class.For example I tried to create new class CSubjectSet but it return the error which states file SubjectSet.cpp and CSubjectSet.h does not exist.

Please help if you encountered this problem before or known the cause of this problem.

Thanks,
Lee

do not use CRecordSet which is the worst in the world.
u need to know how to use database driver (or MFC classes) to read/write data from/to database.

In my opnion, the best are Cdc... (a set of classes, i.e. CdbDatabase, CdbRecordset etc).
please note: second char is lower case: Cdb..., not CDb...
the head file and lib, dll files are available in VC 5.0 but i can not find them in VC 6.0.

according to Microsoft Docs, database issues of VB is based on these classes.

long way to go to really understand these classes, but you have to go if u really want to do some real things.

Hi Micheal,
your sample is for files only: when i right-click a folder on windows explorer, the menu does not appear on shell menu.

i hope the pop-up menu can be applied to any folder, single file or multiple files and folders.

pointer to functions array?

Hi all,
I want to declare a pointer-to-functions array.
Ho can I do that?(For calling them by index)?
Best Wishes,
Thanks.

Re: pointer to functions array?

ThatsAlok28-Jan-05 18:52

28-Jan-05 18:52

Pls Clarify : Signature of each Function would be same or Different.

if function signature are same then here is small code

typedef void (*Hello)(void);
void Func1(void)
{
cout<<"hello you are in function one"<<endl;
};

 void Func2(void)
 {
	 cout<<"hello you are in function two";
 }

 void Func3(void)
 {

	 cout<<"hello you are in Function three ";
 }

 void main()
 {
  Hello hi[3];
  hi[0]=(Hello)&Func1;
  hi[1]=(Hello)&Func2;
  hi[2]=(Hello)&Func3;

  (hi[0])();
  (hi[1])();
  (hi[2])();
 }

I am too finding the way for calling function with different signature by same array using Index

The cast isn't needed and should be avoided as it can lead to bad programming habits.

hi[0]=&Func1; // Works as well...

AfxGetMainWnd()-> PostMessage ( WM_CLOSE )

That will gracefully exit the app just as if you clicked the [X] button in the window caption.
