Turbo C does not support C++/CLI, so you're in the wrong forum. Try the Visual C++ forum

Maybe, but it's not possible unless you can provide specific information so someone can understand what you need.

Hi Mike,
Thanks for your early response.I am sending you the code for my class that needs to be used in .NET .I need to use this control CSizingControlBar in my Winform. CSizingControlBar is derived from MFC class CControlBar.I am migrating an application from MFC to .NET, there are few controls which require a lot of rewrite effort.Hence we wish to reuse the in .NET.It would be a grest help if you could provide with some feasible solution.
You could see one of my classe below.
Thanks

The ToString method will allow you to specify a format. Assuming you're not in the wrong forum and are using .NET

hi ,

i am trying to get the object name, see the code below, but not able to find method, what could be the code in place of ???????.

#include "iostream"
using namespace std;
class A{
public:
int i;
void printObjectname(){
cout << ????????;//<--what could be here, to print the object name as 'objectA'
}
};

int _tmain(int argc, _TCHAR* argv[])
{
A *objectA = new A();
objectA->printObjectname();

return 0;
}

Hi,

this can not be done.

new A() is an object, it could have a name.

objectA is not an object, it is a variable, it holds a reference to the
class A object. There could be many more references to the same object, it suffices
to do A* objectB=objectA;, now how would the class A object have to know
the name of all the variables pointing to it, and in particular the one you want??

Suggestion: give your objects a name by providing a Name property and/or a name argument
in their constructor, so new A("aha"); would create a new class A object and
give it the name "aha". Now you can ask that object for its name, and/or you can override
its ToString() method so it identifies itself. Remark: this works independently of the
variable(s) that may refer to that object!

Smile | :)

Hello. I have to parse an HTML file and extract data from it. Currently I load it into Excel and then save as a .csv file. Then I load the .csv file and parse that. I now have to get the data directly from a web page into .csv format. Has anyone out there attempted something similar. Thank you.

I'm using VC++ 6.00 and Visual Studio 2005. I think IHTMLDocument will help me but I can't figure out how to implement it. I'm scouring the web for an example.

OK, so VC6 doesn't use .NET. VS2005 does. If you're not using .NET then you're in the wrong forum. Try the Visual C++ forum.

Problem with recv() function in winsock.h header file

Raghavendra Pise27-Nov-07 21:13

Hi Friends,

In socket programming I want to connect double byte charcters.
Earlier we used recv() function for single byte charcter.
If we use double byte chracter in below recv function, its coming as a question mark symbol.
If anybody knows how can I handle double byte charcter in Scoket programing(recv function),Please let me know.

My codesnippet:

while( bytesRecv == SOCKET_ERROR ) {
bytesRecv = recv( ConnectSocket, recvbuf, 64, 0 );
if ( bytesRecv == 0 || bytesRecv == WSAECONNRESET || CheckTimeOut()) {
return CloseListen();
}
}

Note:Here recvbuf works for singel byte not for doublebyte charcters.

Thanks in advance.

Using boost test

Hi all,

Is there something in boost that I can use to check if a file is existing and if the file is working.
for example string file = "c://sample.doc", is there something from boost that can see if the sample.doc exists in c: directory?

Thanks,
Jj
