thx.
it works fine on screen - hope the same for printer.

My project was been written in VS 6, when I build it in VS 8 :
error C2872:'unary_function' ambiguous symbol.
How can I resolve this problem?
Thanks forward...

As a first step I would suggest googling on the topic "Breaking changes in Visual C++" and see what turns up. Between version 6 and 8 MS have increased C++ standards compliance, so some older code may well be broken.

Hi,
Having a little trouble with FindFirst File function.... heres what ive got...
include "stdafx.h"
#include <string>
#include <direct.h>
//#include "dirent.h"
#include <winsock2.h>
#include <fstream>
#include <vector>
#include <iostream>
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <sys/stat.h>
#include <stdio.h>
#pragma comment(lib,"ws2_32")
using namespace std;
// Stuff.......
char fileFound[256];
strcpy(fileFound, path1);
WIN32_FIND_DATA FindFileData;
HANDLE hp;
hp = FindFirstFile(fileFound, &FindFileData);
printf ("The first file found is %s\n", FindFileData.cFileName);
FindClose(hp);
The error i recieve is...
error C2664: 'FindFirstFileW' : cannot convert parameter 1 from 'char [256]' to 'LPCWSTR'
I know sometimes when compiling the error is not always what it seeems.. but have no idea..
Please help.
TIA

can you tell me what type of application are you working on?
MFC , Console or On something else because I tried executing your code in MFC application and apart from a very minor change I was able to get the result.

Hi,
Im using Visual Studio 2005 but ive figured that part out via searching long and hard on the web... however im stuck with another problem just the same....
heres what i got for that part....
std::wstring s2ws(const std::string& s){
int len;
int slength = (int)s.length() + 1;
len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0);
wchar_t* buf = new wchar_t[len];
MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);
std::wstring r(buf);
delete[] buf;
return r;
}
#ifdef UNICODE
std::wstring stemp = s2ws(ipp); // Temporary buffer is required
LPCWSTR result = stemp.c_str();
#endif
WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE;
char DirSpec[MAX_PATH + 1]; // directory specification
DWORD dwError;
hFind = FindFirstFile(result, &FindFileData);
printf ("First file name is %s\n", FindFileData.cFileName);
My problem is i cant seem to get the FindFileData function to return a readable string...
but i need FindFileData to be string s; for example...
|
|
|
|
|
Should get it now.
strcat(result,"\0");
hFind=FindFirstFile(result,&FindFileData);
Do you get the name of the file or not?

//ok i fixed part of it but still need to get std::string out of it...
//here is what should be a compilable version of the code fragment...
#include <windows.h>
#include <string.h>
#include <stdio.h>
std::wstring s2ws(const std::string& s){
int len;
int slength = (int)s.length() + 1;
len = MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, 0, 0);
wchar_t* buf = new wchar_t[len];
MultiByteToWideChar(CP_ACP, 0, s.c_str(), slength, buf, len);
std::wstring r(buf);
delete[] buf;
return r;
}
int main(){
string ipp="c:\\";
#ifdef UNICODE
std::wstring stemp = s2ws(ipp); // Temporary buffer is required
LPCWSTR result = stemp.c_str();
#endif
WIN32_FIND_DATA FindFileData;
HANDLE hFind = INVALID_HANDLE_VALUE;
char DirSpec[MAX_PATH + 1]; // directory specification
DWORD dwError;
hFind = FindFirstFile(result, &FindFileData);
printf ("First file name is %s\n", FindFileData.cFileName);
}
//The Return is fine i get First file name is .
//which is what i think im looking for... however
//I still to need to get the string instead of the printed .

what string do you need .
The filename is in FindFileData.cFileName

heres all i could come up with with the find filedata...
string s;
s=(FindFileData.cFileName);
cout << s;
no luck..
error C2679: binary '=' : no operator found which takes a right-hand operand of type 'WCHAR [260]' (or there is no acceptable conversion)
|
|
|
|
|
char *s=new char[255];
strcpy(s,FindFileData.cFileName);
cout<<s;
somethings="" seem="" hard="" to="" do,="" until="" we="" know="" how="" do="" them.

std::string stores char. You need to use std::wstring to store wchar_t. You probably need to read up on unicode. If it's not your intention to use unicode set your project to use multibyte character strings instead.
|
|
|
|
|
strcpy not working... researching info for converting wstring to string....
no luck yet...
|
|
|
|
|
found it...
wstring s= s;
string ssss;
s=FindFileData.cFileName;
ssss.assign(s.begin(), s.end());
cout << ssss;
Thnx for your help
|
|
|
|
|
But then the question you should ask yourself is this. Why are you building a unicode application in the first place?
|
|
|
|
|
your Character set is Unicode Character Set
<br />
LPTSTR lpc;<br />
lpc=(LPTSTR)LocalAlloc(LPTR,256);<br />
wsprintf(lpc,_T("%s"), _T("c:\\code.txt"));<br />
WIN32_FIND_DATA FindFileData;<br />
HANDLE hp; <br />
<br />
hp = FindFirstFile(lpc, &FindFileData);<br />
LocalFree(lpc);<br />
<br />
