I create a small class as following:
class NP
{
public:
int a;
int b;
NP(int m=3, int n=5):a(m),b(n){}
~NP(){}
operator<(const NP&d)//I added this two lines manually
{return a<d.a;}
};
In the tab area of class view, I can see class NP. If I try to overload operator< for class NP through the add member function in the pop-up menu, after I filled all the blanks in the add member function dialog box, when I click OK, nothing happens. What happened?

I tried this and it works well.
Give the function name as operator <.
Then give the parameter type as you want it and a name for the parameter.
The return value can be anything. You can manually delete it later.
If it still doesn't work try deleting the intermediate files and other .ncb files and try.

I don't find anything wrong with the code expect a point noted that you didn't specify the return type of operator <.
Well i usually do this stuff with a friend function 
friend int operator<(const NP& left, const NP& right )
{
return left.a<right.a;
}

Use macro "CT2A()" or "CW2A()"
|
|

Firstly if you are using wide char (Unicode)then CString will be of Type CStringW by default and thus all us need to do is if u have :
CString str;
// do the following
CW2A(str); // this will give u const char*
else if its Multibyte charset project CString will be of type CStringA by default:
// u can directly cast it to char* as below:
CString str;
//do the following
(CHAR*)str.GetString();// this will give u Const char*
If you like this ans mark it and close the thread

Hi all,
I am new to opencv and I want to use it. But Before the application starts an error appears:

Please help me(I am using opencv2.0 and running windows vista)
Thanks.

Have you narrowed the problem down to OpenCV? In other words, what happens if you cerate a new project that does not use OpenCV?

I have the problem with opencv only... I have included all the files and libraries...
Then I write a simple code that uses opencv libraries... Then I debug the app and the error appears... Before even clicking on the button that contains the code...

Are you implicitly or explicitly linking with their libraries? Have any global OpenCV-related objects been declared?

I have global declarations of opencv classes and I am using "additional dependencies" section in Linker options.

Classes or objects? Global objects will be instantiated before your "main" function gets called. That may be where the error is happening.

Basic question. I assume you managed to build the OpenCV libraries and/or DLLs successfully? Also, do you know about the OpenCV support group on Yahoo Groups? You may have better luck there since it's a specialized support group.
You measure democracy by the freedom it gives its dissidents, not the freedom it gives its assimilated conformists.

hi, maybe already is late, but like aditional information, i got the same problem and i solved, a had put cv210d.lib; cvauxd.lib; etc. in the entry of Link in properties window, I erased the letter 'd' cv210.lib; cvaux.lib; etc. and the message "The application was unable to start correctly (0x0150002)" no appeared other time.

Hello
Is there anyway to force the background of a dialog to be visible? For some reason all my dialogs have lost their bgs although I can't find a call within my code that uses WM_ERASEBKGND.
In order to see whether if was the dlgs themselves, or something else I constructed a basic one. It was created using all the default settings in the VS resource editor. The problem still occurs. I can attach the code for this basic dlg but the post will be quite long.
If there is no way to force the background to be visible, does anyone have any idea of what might have caused this? The buttons and other items in the dlgs are visible, just not the background or title-bar.
Many thanks in advance for help offered.

Visible:
- buttons
- text in text-boxes (editable and static)
Missing:
- dialog background
- text-box background
- static-text
- title bar
Other:
- space where dialog background would be renders whatever is immediately below it
- space where text-box background would be renders desktop background
Hope that clarifies enough to assist

I'm clueless. It almost sounds intentional rather than accidental. What version of VS are you using?

Did you set the property "transparent" to true?
