Help with Conversion from Sting to Char

Diederick · 11-30-2005, 07:11 AM

Im working in Visual Studie.NET in Visual C++, and I want to convert my sting into a chat, i want just the first letter of the sting to be my char:

String *name = "Dennis";

now I want the 'D' from Dennis to be in my

char letter;

variable. Without the error: possible loss of data.

My Code at this stage is:

String *name = "Dennis";
String *firstLetter = name->Substring(0,1);
char letter = System::Convert::ToChar(firstLetter);

but I keep on getting "possible los of data" error.

Please help.
Thank you -
Diederick

Couldn't you just do:

Code:

	std::string name = "Dennis";
	char letter = *(name.c_str());

Hi,

The .NET framework used multi-byte characters. In short you need to use the .NET wrapper class Char (note the capitalised C) rather than the C++ type char. The .NET multi-byte character is equivalent to the C++ wchar_t or wide character. I don't know if there is a conversion from Unicode (multi-byte character) to ANSI (single byte character) but if all you require is to grab the first character then Char should be sufficient and you program will support I18n - or at least not break from it at that point
