The unregister functions name is this: DllUnregisterServer, with a lowercase R in unregister.
You typed it like this:
DllUnRegisterServer with a capital R.
Good luck

I am not receiving 'OnReceive' event on receiving data from the network. It seems the library didn't get the frame. I saw the frame on the protocol analyzer but did not get any 'OnReceive' event on the socket. I even checked with synchronous socket (CSocket) but could not receive a single byte. This problem however doesn't always appear. Sometimes it is working and sometimes it is not. What might be the reason for such random behaviour ?

I am over-riding operator new []. I am getting the following error....
c:\Visual Studio Projects\JLib\main.cpp(149): error C2661: 'Object<T>::operator new[]' : no overloaded function takes 3 arguments
The following code results in the above comilation error.
Object<double>* objects;
objects = new Object<double>[5]; // <- error occurrs here
delete [] objects;
If anyone knows what is going on I would very much appreciate an explanation.
Here is the relevant declarations and definitions...
#pragma once
#include <new>
using namespace std;
template <typename T> class Object{
public:
//CONSTRUCTORS ETC ETC ETC
void* operator new[](size_t size) throw(bad_alloc);
void* operator new[](size_t size,const nothrow_t&) throw();
void operator delete[](void* ptr) throw();
void operator delete[](void* ptr,const nothrow_t&) throw();
//OTHER STUF
};
template <typename T> void* Object<T>::operator new[](size_t size) throw(bad_alloc){
Object<T>* data = 0;
if ( (data = ::operator new[](size){
//ommitted for brevity
}
return data;
}
template <typename T> void* Object<T>::operator new[](size_t size,const nothrow_t&) throw(){
Object<T>* data = 0;
if ( (data = ::operator new[](size,const nothrow_t&)) ){
//ommitted for brevity
}
return data;
}
template <typename T> void Object<T>::operator delete[](void* ptr) throw(){
::operator delete [] (ptr);
ptr = 0;
}
template <typename T> void Object<T>::operator delete[](void* ptr,const nothrow_t&) throw(){
::operator delete [] (ptr,const nothrow_t&);
ptr = 0;
}

You may use
void* operator new(size_t size) throw(bad_alloc);
instead
void* operator new[](size_t size) throw(bad_alloc);
wer ever it is used so ....

I need to define an implementatino of the [] version because the instances of Object<t> have data regarding adjacent instantiations when created via new [] . At least logically they do, so it makes sense to set those relationships in the new construction.

Can you help reproducing this error ?
I tried this way.
template <typename T> class A
{
public:
void* operator new[](size_t t) throw();
};
template <typename T>void* A<T>::operator new[](size_t t) throw()
{
return NULL;
}
int main(int argc, char* argv[])
{
A<double>* objects;
objects = new A<double> [5]; delete [] objects;
return 0;
}
But no error occurs.

The only difference between your use of the new operator and mine (using your class) is...
Your version:
A* objects;
objects = new A [5];
delete [] objects;
return 0;
My version:
A<double>* objects;
objects = new A<double> [5];
delete [] objects;
return 0;
I dont understand how your code can work without the template type being defined.

Actually, I added < and > there,but suppressed due to html formatting(In all other places I used "andlt and andgt" . I modified it now.
And its working fine. Am I missing something?

I have a wizard that I created with a propertysheet and 3 propertypages. All have about a half-dozen controls for gathering data. The problem is I don't know how to store the data variables from one page to the next so that at the last page I can use it other than writing it to a file when next button fires.
Thanks!

How about storing the data to the global variables?

keep your data in a structure/class, and pass the reference to the each pages. in case of any validation, do it in corresponding page. gotcha?

Use variables for storing each control value, in respective propertypage class.Validate its values when user press next button.
In last page, you can use this code.
CPropertySheet *pSheet=GetParent();
CPropertPage* pPage1=pSheet->GetPage(1);
pPage1->Aceess variables;
CPropertPage* pPage2=pSheet->GetPage(2);
pPage2->Aceess variables;

The common link between all of the pages is the sheet. Store the data there.

Hi.
I have a capture graph running (capturing video frames from a webcam)and if windows media player (or winamp) visualization is switched to full screen mode, my graph just seems to freeze. Nothing happens, no video, no errors, no events, nothing. When full screen mode is switched off everything goes back to normal.
Help anyone?
Thanks

Just started with C++ a few days ago. Everything going good but need some help with classes - ifstream & ofstream.
Need to be able to display the contents of a text file in a console application. Also any info on how to output to a text file. Have included fstream header but just not getting my head around it !!!!
Most web sites visited just dont seem to be providing the info I need.
Any help with basic code included or good links would be much appreciated !!!!!!
Thanks in advance for any info.

An ifstream will attempt to read any type using the >> operator. An ofstream will write any type using the << operator. So, if you create a std::string, you can read a file a line at a time like this :
ifstream file("iostream test.txt");
std::string s;
while (!file.eof())
{
file >> s;
// do something with s
}
Now, std::endl is the end of line character, you need to insert this as it's used as a delimiter. The same is true if you're writing a file a line at a time.
