Rather than returning the value, pass the paramter as a reference.
void myclass::getStr(CStringArray& csa)
{
csa.Add("str1");
csa.Add("str2");
}
|
|
|
|
|
This is my code snippet, and it does not work, since CStringArray does not implement a copy constructor (meaning that this probably fails to compile:
CStringArray csa=getStr();
Do as suggested above, pass the CStringArray as an argument to the function.

maybe it is some helpful to you
////h File////////////
CStringArray *a();
CStringArray* CAnswer::a()
{
CStringArray* a;
a=new (CStringArray);
a->Add("123");
a->Add("12");
return a;
}
if you check count then return ->2
CStringArray *b;
b=a();
int cb=b->GetCount();

Hi,
Works. Yet not a good solution. The caller is supposed to delete the array though it may not do it.
The best choice, I think, is to pass by refernce as a parameter.

yes
It's only a suggestion because we need to delete array

Hello,
My problem is I want to create child windows of user defined sizes in the MDImainframe window once it shows and show various documents in them, so I required some help regarding how to create a MDI child winodw or get the MDI child window pointer to create it? May be a similar example. Please help.

Using GetActiveFrame() get a pointer to the active frame.
Next use GetWindow to traverse through all siblings of the frame window.

Hi,
There are so many gurus here who are doing the VC++, COM, ATL , MFC programming. Could people share the interview questions they faced with these technologies. There are rarely any site which mentions the interview questions for these programming skills. Any link to site if anybody knows.
Thanks,

Here is a question to you on C++: Can a class constructor be declared private? If not, explain why. If yes, explain why you would do it.
|
|
|
|
|
For those who don't know, Yes it can! You would use this if you wanted to prevent anybody creating this object with a call to "new". Therefore the object itself must control it's own creation and deletion.
Another question if you are in the gaming industry may be something like:
What is a quaternion, why is it different from Euler and what are the advantages/disadvantages of both?

This is not a question. What is it that you want ?
~RaGE();

I want to know hwo to proceed with it.
Which base classes to be used. How can be the
things combined.
Thank you

Hi all,
In my MDI application, I've drawn an image as the background in OnEraseBkgnd() function. I'd like to keep the image always in Center. But I'm not able to get the center of the window in OnSize. If anyone could help to come out of this problem, it would be quite helpful for me.
Thanks in advance,
Sarvan AL

Well it's easy.
Take the width of the image.
Take the height of the image.
Now the cx parameter in OnSize will be the width and cy will be the height.
So how will you position the image in the centre?
int midX = (cx-bmpWidth)/2;
int midY = (cy-bmpHeight)/2;

Thanks Nibu,
I've forgotten to call Invalidate() in OnSize().
Thanks once again,

Hi,
I am a total beginner. How do I stop from the black screen which displays the result of execution to automatically dissapear?. It came out in a blink of an eye and then of it goes.
I just want to print out a simple "Hello World" message.
Thanks.

Hi
I have understood your problem.
If your are creating the console application you would be pressing the F5 button. In this case the windows diaplays the result for your execution but just dissappears. For this you have to press CTL+F5.

I'm using Dev C++. The command to run is F9

In case if you don't have any issue in using C functions in C++, then include conio.h and add the following code at the end of function.
cout << "Press any key to exit.";
getch();
|
|
|
|
|
Another solution is to call system("PAUSE");
|
|
|
|
|
Open a command prompt and run your program from there rather than from within the IDE. That is why the window is quickly disapearing.

In C++, inline keyword is a request to a compiler. Compiler can ignore it.
Apart from poking through .asm files, is there any way to to find the list of inline function(s) for which compiler has ignored the inline keyword? May be some compiler setting(s) to generate the report containing this information.

key word inline must be in h file.
if u put inline in c/cpp files, it is ignored.
inline means once.
if only one c or cpp file includes the h file in a project, the key word inline may be ignored (upto compiler).
if more than one c/cpp files include the h file, key word inline is NOT ignored.

It seems you didn't get my question.
I don't have any doubt in how to use inline. I know all the rules of inline.
What i am asking is how to find the list of inline function(s) for which compiler has ignored the inline keyword?
