This is incorrect. If your class has built-in data types (int, char, etc.), the default behavior is to leave them uninitialized, just like local variables.

In addition to above points from superman,
i will say always declare and define your own default constructors when your class is having pointer members.
Along with default constructor, make your own copy constructor and operator = in that case.
It is always good to write your own default constructor so that you can initialize your member variable in default constructor.

Hi.
I want to restrict entering unicode characters in the edit box on a dialog. Could you please give any idea to handle this.

Gday,
You need to look into input filtering. It's just a matter of sub-classing the edit control, passing only the allowed characters as input, while discarding undesired ones.
Here's an article that deals with input filtering. Enhanced Focus Edit Control with Input Filtering[^]

Hi,
I am trying to create a c++ dll in vs2008 and I have exported the sample function and class available in the files created (by using the export symbol option when the dll created). My problem is that whenever I try to call a the dll I get an error saying that no entry point is found in the dll.
I have manged to get C++ dlls working with vs 2005 and by using dllexport, however things seem to be a little different in vs 2008.
Any help is much appreciated.
Thanks

The syntax for exporting functions and classes have remained the same for a very long time and it has not changed with VS 2008.
You need to give some more information like -
How are you linking the dll to the exe.
In which language and VS version is the exe developed in.
Some code snippets would be helpful.

Hi,
Thanks for the reply.
I am linking the dll to the exe using P/Invoke. The exe is developed in C# VS 2008.
When I use the export symbol option when creating the dll it creates a sample class with a constructor and a independent function (which are said to be exported). I am not sure how to instantiate this class or to call the independent function from the C# application.
|

|

Not totally sure, but I think P/Invoke only supports "C" linkage.
That means you can call exported functions but not exported classes.
If so, you will need to create a wrapper in C++ that export only functions and these functions can delegate function calls to the C++ class.

Thanks for the info. I'll check out using a wrapper. It would be nice if I can get the class exported also.

Yes.. SetWindowText is not a member of CString.
I assume you are using a textbox. make a variable of control type.
Something like this
CEdit m_edit
and then compile the code.Hope this helps.

Wanting to know how to create payload as a block of binary data for DNS packet.

char *buffer;
buffer = new char[bufferSize + extraSize];
sendto(socket, buffer, bufferSize + extraSize, flags, &destAddr, destaddrSize);

im using Nemesis DNS generator so im going to call the file to be used and within the file are only datatype and i use the %c and %s to identify dateype when formatting the output
fp = fopen ("datafilename.dns"), "w");
fprintf(fp, "%c%c%c%c, 0x00, 0x01 ")
fprintf(fp,"%c%s, 0x03, "www");
etc......
fclose(fp);
your code may do the same but i am not a strong programmer and was wonder if you could explain if you code does what this does and point me to some reading material

The html content was downloaded from host with security info, such as Credit card number, IP address, user password etc.
I need to display the memory html file directly on a dialog without saving it as temp file for launching by IE or MS-Web-Browser because of security reason (delete file doesn't work always and is dangrous).
Do you know how to do this?
Thanks.
