Filter by week: 1 2 3 4 5 Expose C++ array through managed wrapper class. Posted by joshuapking NO[at]SPAM gmail.com at 12/14/2006 9:52:22 PM I'm having a very difficult time coming across an appropriate solution
for this seemingly simple problem. I've written a managed wrapper
class for some legacy C++ routines. One routine generates an array of
ints, which I wish to expose through the managed wrapper. The managed

New/delete vs. declare/garbage-collect Posted by Vincent Fatica at 12/14/2006 7:20:20 PM I noticed that if I give MY_STRUCT a simple c'tor and d'tor, say,
MY_STRUCT::MY_STRUCT()
{
hEvent = CreateEvent(...);
}
MY_STRUCT::~MY_STRUCT
{
CloseHandle(hEvent);
}
then using a local instance via simple declaration,
INT my_function()
{
MY_STRUCT foo;

VC++ 2005 - Compilation Errors using "ifstream" Posted by marathoner at 12/14/2006 3:31:59 PM I tried your advice, and replaced "ifstream" with "std::ifstream". I also
replaced instances of "ofstream" with "std::ofstream". Those syntax errors
were resolved.
When I added "std" to the following statement: m_InFile.open(m_sFileName,
ios::in | ios::binary);
which became

VS2005 Command line compilation errors Posted by wxforecaster at 12/14/2006 2:44:36 PM As alluded to in my post yesterday, I'm trying to compile a common C utility

It's only reference is to zlib.h, which needs zconf.h and in turn libz.a
On Unix I've compiled this with success by running: gcc -lz -o foo.exe foo.c

Trouble porting simple class from MEC++ to C++/CLI Posted by Bern McCarty at 12/13/2006 3:00:25 PM
I have a simple ref class in its own namespace that needs to coexist with

the identifier as itself. Everything compiles fine with the old MEC++ syntax,
but I cannot figure out how to write the code so that it will co...more >>

How to use DrawDibDraw Posted by ulillillia at 12/12/2006 9:52:00 PM I'm trying to learn programming and I've got quite far so far, but I've run

wrapping C++ API with virtual functions Posted by Gerhard Prilmeier at 12/12/2006 1:15:15 PM Hello,
I have an unmanaged C++ API that uses virtual functions, like this:

};
The user would use A by inheritance:
class B : public A

void handleMe(){ /* doSomething */ }
};

Implementation changes for function pointers Posted by A Wieser at 12/11/2006 6:43:15 PM Hello,
It seems something's going on with regard to the way Visual Studio 2005
