Using & to get an address of a variable can be problematic if the variable type has overloaded operator&(). For example, _com_ptr_ has operator&() overloaded with a side effect of modifying the object. Now I have a complicated set of templates with functions like this: template<class T> void process( const T* object ) { //whatever ...

I am learning c++ and I am trying to better understand it. I was reading the msdn documents on how to use xml lite. it said that I must use a class that implements the IStream interface. It said to declare and instantiate my class that extends Istream and use CComPtr when declaring the varible. then it showed me the following. CComPtr<I...

I am using Visual Studio 2008 to run an application, which loads a number of DLL's at startup, that immediately exits with "The program '[3668] cb_tcl.exe: Native' has exited with code -1072365566 (0xc0150002)." Unfortunately I get no other clues about the source of the problem and the exit occurs before the program starts, but I suspec...
Hi, i am currently working on a project which deals with the reading of satellite images of ".0FM" format and its size is around 8Mb. Now i have been successful in converting the file("*.0FM") content into a byte array. Now the byte array has integer values ranging from 0 - 255. I have to display this byte array in a picturebox control....

Visual C++ has function-level linking. Looks like it's a great thing - it can reduce the size of generated executables. Does it have any negative effects? Will I have to pay anything for the advantages of this option or can I just turn it on and enjoy the benefits? ...
Hi, I am currently writing a plugin in C++. For my functionality I ask the API to save out a file. The API gives me a return value when the file is written... or so it seemd. The problem is, that this return value is returned too early so that I can not be sure, that the file is written completely. Is there a possibility of checking t...
hello i have a problem i use visual studio 2008, and i chose a .cpp in visual c++ at first i copied a tutorial sample #include <stdio.h> int main() { int x=1; int n =1; printf("Wie viele Zahlen wollen sie ausgeben lassen?: "); for(int i=0; i < n; ++i) { x*=i; // x=x*i printf("%d: %d\n", i, x); } return 0; } but i get ...
Hi, There was a program what I could compile under 2008 for a while. Note I can compile the program using cl and in Ultimate++ IDE. It is a fairly large program , so I am not going to post it here.

AfxBeginThread(WorkerThread, this, THREAD_PRIORITY_NORMAL, 0, 0); But the compiler complains that error C2065: 'AfxBeginThread' : undeclared identifier But in MSDN i found that AfxBeginThread is found in AFXWIN.H If I include AFXWIN.H, the compiler...

I am writing a c++ static library A.lib in visual studio 2008. In my static library, I am using few APIs exposed by another static library B.lib(.lib). I have a written an application that uses A.lib. Since few header files in A.lib are using headers from B.lib, my application wants a path of B.lib header files. How can I avoid my appli...

I want to get this straight. I know what DLL's are. I have done research on them. they are like executable except they can not be access directly. Their main purposes are to provide additional resources such as functions and variables for your application. What I do not understand is. Do you have to include the header for both libs and ...
Is this scenario even possible? class Base { int someBaseMemer; }; template<class T> class Derived : public T { int someNonBaseMemer; Derived(T* baseInstance); }; Goal: Base* pBase = new Base(); pBase->someBaseMemer = 123; // Some value set Derived<Base>* pDerived = new Derived<Base>(pBase); The value of pDerived->someBase...
When I use function-level linking in VC++ for a simple project it's more or less clear how it works. But what if I build an executable that depends on a static library and both are compiled with VC++? For example, if the static library had function-level linking enabled and the executable has it disabled or vice versa - how will it work...
