Ошибка e0304 visual studio

DisplayMap.insert(i, map[i]);

As you can see in the above sample, I’ve tried to use the insert function, but it keeps displaying the same E0304 Error, which is for an overloaded function. In VS2019, the error details are:

Severity    Code    Description Project File    Line    Suppression State
Error (active)  E0304   no instance of overloaded function "std::basic_string<_Elem, _Traits, _Alloc>::insert [with _Elem=char, _Traits=std::char_traits<char>, _Alloc=std::allocator<char>]" matches the argument list

The error says that the arguments don’t match because the different overloads have different arguments.
Can you help me solve this error?
Here’s my full code if you need it:

#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include <Windows.h>
#include <conio.h>
#include <algorithm>
#include <string>
#include "Data.h"
using namespace std;

int main() {
    SetConsoleDisplayMode(GetStdHandle(STD_OUTPUT_HANDLE), CONSOLE_FULLSCREEN_MODE, 0);
    CONSOLE_SCREEN_BUFFER_INFO csbi;
    int WindowColumns, WindowRows, DisplayBuffer;
    string DisplayMap;
    GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi);
    WindowColumns = csbi.srWindow.Right - csbi.srWindow.Left + 1;
    WindowRows = csbi.srWindow.Bottom - csbi.srWindow.Top + 1;
    cout << WindowColumns << "," << WindowRows;
    DisplayBuffer = WindowColumns * WindowRows;
    for (int i = 0; i < WindowColumns; i++) {
        DisplayMap.insert(i, map[i]);
    }
    return 0;
}

Thanks In advance.

EDIT:
Data.h here:

#pragma once

#include <iostream>
#include <String>
using namespace std;
string savedMap = "                              "
"                              "
"                              "
"                              "
"                              ";
string map = savedMap;
int w = 119, a = 97, s = 115, d = 100;
char key_press;
int myPOS = 35;
int MDPOS = myPOS, ascii_value;

Please don’t ask me why I use the namespace std in a header file.

So we have this old project that was originally written in MSVC 6.0. The language standards are mostly C-based, although we’ve moved the project over to C++ v17 on VS2017. This project compiled just fine before the latest VS update.

After updating VS to 15.7.0 (and adding the Windows 10 SDK 10.0.17134), the project will still compile, but Intellisense drops hundreds of E0304 errors like the following:

Severity	Code	Source	        Description	
Error (active)	E0304	IntelliSense	no instance of function template "__countof_helper" matches the argument list	
  

Every single one of these calls (or at least every one I looked at) was calling
_countof like this snippet:

TCHAR ErrMsg[ERR_MSG_SIZE] = { (TCHAR)NULL };

...

FormatErrorString(GetLastError(), ErrMsg, _countof(ErrMsg), true);

If I try to «Show Error Help» on the error in the error list, it does nothing.

Has anyone else run into this or have some advice on why or how this has occurred?

Additionally, if it helps…

This project is:

— Targeting Windows 10 as a platform

— 10.0.17134.0 as the Windows SDK Version

— has 64-bit config (UNICODE defined) and 32-bit config (UNICODE
not defined) profiles

— using «C++ 17 Standard» as the C++ Language Standard

— does not use MFC or CLR

I can include all the miscellaneous options if that helps, but I think that covers the major variables. Some of these options are intentional due to certain constraints in our software environment and/or integration requirements.

Thanks for any feedback.

Hello friend, I am super beginner. I am trying to run this example code http://www.asic-world.com/systemc/first1.html#Counter_Design_Specs  counter design and counter testbench on my  systemc with visual studio. So I got two error. Here I put the error together.

  • Severity    Code    Description    Project    File    Line    Suppression State
    Error (active)    E0304    no instance of overloaded function «sc_start» matches the argument list    Project1    C:Users60182sourcereposProject1Project1first_counter_tb.cpp    17    
     
  • Severity    Code    Description    Project    File    Line    Suppression State
    Error    C2665    ‘sc_core::sc_start’: none of the 4 overloads could convert all the argument types    Project1    c:users60182sourcereposproject1project1first_counter_tb.cpp    17

The example you are refering to is for SystemC 2.0 and more over has errors. Actually this is a bad example to start with.

  • the sc_start() in line 17 needs to be commented out for 2 reasons: a) it doesn’t make any sense and b) it runs elaboration and tracing (VCD) needs to be initialized before that. After elaboration you cannot add signals for tracing anymore
  • sc_start() (lines 32, 34, 40, 42, 47, 49, 56 58) has to be called either without any arguments (so it runs to the end) or with a duration in terms of sc_time like this:

    sc_start(1, SC_NS);

My recommendation would be to either use  the Doulus tutorials: https://www.doulos.com/knowhow/systemc/tutorial/ or the stuff from SCLive (https://sclive.wordpress.com/)
