How can i set other encoder like windows-1250 without using default?
You can use Encoding::GetEncoding("windows-1250")

Thanks for the help.
Do you know where can i get entire list for encoding?

Are you trying to use CCW on the Quartz library (I assume it's a COM library). And if so, in what way is it not working? You said Duration failed - do you mean that a call to GetDuration failed?
If the error is more on the COM side, you might have to repost this question in the COM forum.

After having such a piss-poor time with VS2005 destroying WinForms whenever I alter resX files, I gave up on it and put string literals directly in code. Now that I'm going back and doing cleanup, I want to remove those and put them into a resource file. Has anybody else had this same problem with C++/CLI projects? If so, how are you managing string resources?

If you can outline the minimal steps to reproduce the problem, I can check if I get it too.

I asked the same question on the MSDN forums and received a good suggestion to create a second resX file and placed localizable strings in there. I think I'm going to do that.

Hi,
i've made a managed wrapper(Managed Extensions) for a class, that was written in C++ with VS 6.0.
It works very fine but here's my problem:
I'd like to debug code of my C++-class. Any searches with google led to nothing.
Hope here in this discussion board there are some people who can help me ?
My environments:
VC++ 6.0 which i compiled the dll (source is available)
VS++ 7.0 2003 2 project: 1 project defines a managed wrapper which delegates all methode-calls to
the aggregated C++-class.
Thanx in advance

VC 2003 does support mixed-mode debugging, but it's slow and doesn't work well all the time. You could force a debugger break by using an __asm int 3

hello nish's,
this is right and i can set this debug-property, but
it wouldn't work practically ? If i debug, it will not jump into
source-code of the dll-VC6.0 project.
Have i set another switch or something else ?
thanx

It's been a while since I used VC 2003 to do a managed DLL, but if I remember right, it does break into the source code for the VC6 DLL, provided there's debug information in it.

Hi,
I've just got Visual Studio 2005 Standard Edition and was writing a new CLR class
using this code
<br />
#using "System.dll"<br />
<br />
using namespace System;<br />
<br />
<br />
public ref class SimpleClass<br />
{<br />
public:<br />
SimpleClass();<br />
SimpleClass(System::String^ str,System::Int32 age);<br />
~SimpleClass();<br />
<br />
System::String^ GetName() {return _str;}<br />
void SetName(System::String^ str) {_str = str;}<br />
System::Int32 GetAge() {return _age;}<br />
<br />
private:<br />
System::Int32 _age;<br />
System::String^ _str;<br />
};<br />
<br />
SimpleClass::SimpleClass()<br />
{}<br />
<br />
SimpleClass::~SimpleClass()<br />
{}<br />
<br />
SimpleClass::SimpleClass(System::String^ str,System::Int32 age)<br />
{<br />
_str = str;<br />
_age = age;<br />
}<br />
then i wrote a cpp file
<br />
#include "simpleclass.h"<br />
<br />
int main()<br />
{<br />
SimpleClass SC = gcnew SimpleClass("Bob",13);<br />
<br />
Console::WriteLine(SC.GetAge());<br />
<br />
<br />
return 0;<br />
}<br />
I tried two modifactions both using the new '^' handle operator and normal class by saying
SimpleClass SC = gcnew SimpleClass().
However when i tried using "gcnew SimpleClass() it came up with error, no copy constructor.
So I wrote this :
<br />
SimpleClass(const SimpleClass& rhs);<br />
and it came up with several errors.
How do you write a copy constructor in C++ 2.0 please 
Thanks 
Tom

>>SimpleClass SC = gcnew SimpleClass();<<
SC is not a handle type. gcnew returns a handle.
You need to do one of these :-
SimpleClass^ SC = gcnew SimpleClass();
or
SimpleClass SC; //stack semantics
You don't need a copy constructor.

Nish

Hi Nisht,
Thanks for the help!
I wanted to use like the class like this.
public ref class Class1 {
public:
void foo() {Console::Writeline("Hello World");
}
Class^ C1 = gcnew Class1();
C1->foo();
Class C2;
C2.foo()
Can that be done with managed classes.

I can make any of my MC++ classes have static properties (via the property keyword), but how can I create a property list dynamically at runtime?
Example?

You cannot alter a class at runtime. You could attempt to dynamically create a new class derived from another class and then instantiate it dynamically at runtime.

Does anyone have the source code for calulating the hyperbolic sine of an unknown angle, preferable in radian, ( sinh x )?
using the standard library of sine is not allowed.
therefore im stucked at quite beginning.
anyone can help me please?
im doing this for my project.
thank lots...

You could look at the Standard Library sources, couldn't you? BTW, please be aware that this is the C++/CLI forum.

Hello,
Here is my environment:
Visual Studio .NET 2003 Fr
Framework: 1.1 SP1
OS: Win2000 pro SP4
I want to instanciate some class of an older none-MFC DLL which was compiled in C++ 6, from a new C++ .Net application. I have all .h, .lib and .dll files of this library.
My goal is to create a wrapper of this DLL in C++.NET in order to use it in a C# project.
Is it possible to make such wrapper ? and what is the right way to do it ?
Thanks for your answer.
PS : Sorry for my English, I'm french

Yes, what you intend to do is very much possible. I assume you have a DLL that exports some native C++ classes. You can write a C++/CLI mixed-mode DLL, that contains managed classes that wrap these native classes. Accessing the native DLL from the mixed-mode DLL is the same as how you would have done it in the pre-.NET days. Go ahead and try it out. You can post any issues you run into on this forum.
Regards,
Nish

Thanks for your support
After some tries, I sill got a problem at built time and I think it's a big one.
I think it's due to my native DLL which is compiled with STLport and ZThread Libraries 
Here is the summary of what I've done :
I made a .net class library project. I added the good .lib and lib path in the link tab, the good include path in C++ tab, the good #include in my '.h' and click generate the soluce.
And .net said to me:
<br />
E:\Library\STLport-4.5.3\stlport\stl\_string.c(337): error C2143: erreur de syntaxe : absence de ';' avant '_STL::basic_string<_CharT,_Traits,_Alloc>::find'<br />
In english, it looks like this (I think):
<br />
E:\Library\STLport-4.5.3\stlport\stl\_string.c(337): error C2143: syntax error: no ';' found before '_STL::basic_string<_CharT,_Traits,_Alloc>::find'<br />
This error corresponds to the following code in the file "_string.c" of the STL:
<br />
template <class _CharT, class _Traits, class _Alloc> __size_type__<br />
basic_string<_CharT,_Traits,_Alloc> ::find(const _CharT* __s, size_type __pos, size_type __n) const <br />
{<br />
if (__pos + __n > size())<br />
return npos;<br />
else {<br />
const const_pointer __result =<br />
_STLP_STD::search((const _CharT*)this->_M_start + __pos, (const _CharT*)this->_M_finish, <br />
__s, __s + __n, _Eq_traits<_Traits>());<br />
return __result != this->_M_finish ? __result - this->_M_start : npos;<br />
}<br />
}<br />
If you have an idea of how can I solve this problem, I take it !!
Else I will continue to burn some candles at my village's church :-p
C U.
