Moving files from one directory into another - c++

Question

I would like to copy all files from test1 into test2. The code compiles but nothing happens.
#include <iostream>
#include <stdlib.h>
#include <windows.h>
using namespace std;
int main()
{
string input1 = "C:\\test1\\";
string input2 = "C:\\test2\\";
MoveFile(input1.c_str(), input2.c_str());
}
I was considering xcopy but it would not accept a pre defined string. Is there a work around?

Answer 1

std::string GetLastErrorAsString()
{
//Get the error message, if any.
DWORD errorMessageID = ::GetLastError();
if (errorMessageID == 0)
return std::string(); //No error message has been recorded
LPSTR messageBuffer = nullptr;
size_t size = FormatMessageA(FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_IGNORE_INSERTS,
NULL, errorMessageID, MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), (LPSTR)&messageBuffer, 0, NULL);
std::string message(messageBuffer, size);
//Free the buffer.
LocalFree(messageBuffer);
return message;
}
int main()
{
string input1 = "C:\\test1\\";
string input2 = "C:\\test2\\";
if (!MoveFile(input1.c_str(), input2.c_str()))
{
string msg = GetLastErrorAsString();
cout << "fail: " << msg << endl;
}
else {
cout << "ok" << endl;
}
system("pause");
}
Your code works for me, you may have to set the character set to use multi-byte character set in your project properties.
If not, provide us with the error.
Check if you have the write rights on C:.
Check if there already is a test2 folder in C: (or if there is not a test1 folder in C:).

I resovled the issue by removing the \\ from test2. Folder test 2 doesn't exist. Thank you for the replies and the test code. I think SHFileOperation will be a better option as I have to transfer files from a floppy to my C drive. string input1 = "C:\\test1\\";
string input2 = "C:\\test2";
