All ok, i forget the () behind .ToString
(i begin in programmation :) )
Another question, how can i optimize my code? because my program is
50ko, and use more than 15sec. to appear on my screen!!
It is normal for a .Net Application?

Thanks for your help ;)

Hi there! I've been having a lot of difficult trying to figure out a way to convert a terminated char array to a system::string for use in Visual C++ .NET 2003. This is necessary because I have some legcay C code that needs to process a string taken from a textbox, then I need to re-display the string as the textbox->Text. I easily found how to convert from system::string to char but I can't figure out how to go the other way!!

Hello, I am working on cleaning up some code that I inherited and was wondering if there is anything wrong with my function. I am fairly proficient in standard C++ but I am pretty new to the .NET managed C++. It seems to work fine, but everyone knows that programs with errors can still appear to "work fine" :) I am working with VS .NET 2003; I am unable to upgrade to 2005 at this time, so I cannot use the newer syntax or features. ...

I have seen the following function to convert from a System::String^ to a const wchar_t*. I would like to get a LPCTSTR and AFAIK LPCTSTR is equal to const wchar_t*. Then it should all work right? But I only get the first character. And when I try to do std::wstring l_s(convert(somestring)) I get really strange characters into l_s string representation, but when I check l_s individual characters they look ok. const wchar_t* convert(...
