problem with including

[hamsterman]

Hi

Im making output with files.

//...
//lots unrelated code in both sides
#include <fstream>

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
	ofstream output;
	output.open("output.txt");
	output<<"Helo world";
	output.close();
//... 

but when i compile i get errors:

.\main.cpp(31) : error C2065: 'ofstream' : undeclared identifier
.\main.cpp(31) : error C2146: syntax error : missing ';' before identifier 'output'
.\main.cpp(31) : error C2065: 'output' : undeclared identifier
.\main.cpp(32) : error C2228: left of '.open' must have class/struct/union
type is ''unknown-type''
.\main.cpp(34) : error C2228: left of '.close' must have class/struct/union
type is ''unknown-type''

Please help.

Try:

//...
//lots unrelated code in both sides
#include <fstream>

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{
	std::ofstream output;  

	output.open("output.txt");
	output<<"Helo world";
	output.close();
//...

sory for such stupid mistake but now i have another problem:

I can't think of a reason that you would get that error from the code that you have posted.

If you want to rule out the ofstream stuff as the coarse of the error, comment it out and recompile, see if the error goes away.

Try searching your code for 'constant' and see what comes up, It looks like it is related to a function called move.

when I comment ofstream stuf program works well but its enough to #include <fstream> and the error comes back.

constant and move are in the iosfwd file
(here are lines 229-235)

	_SCL_INSECURE_DEPRECATE
	static _Elem *__CLRCALL_OR_CDECL move(_Elem *_First1,
		const _Elem *_First2, size_t _Count)
		{	// move [_First1, _First1 + _Count) to [_First2, ...)
		// assume there is enough space in the destination buffer
		return _Move_s(_First1, _Count, _First2, _Count);
		}
