Reading a Text File w/ WIN32

c++, file-io, winapi

Solution

Is there a simple method of reading a text file line by line?

Yes:

{
  std::ifstream hFile(filename);

  std::vector<std::string> lines;
  std::string line;
  while(std::getline(hFile, line))
    lines.push_back(line);

  return lines;
}

Problem

I'm trying to parse a text file with a win32 program in c++. Is there a simple method of reading a text file line by line? My text file consists of strings that I would like to store in a char array(const char* cArray[67]). Here is what I have so far. I am using CreateFile and ReadFile. I get an access violation error(0x000003e6) from readfile: ``` CDECK::CDECK():filename(".\\Deck/list.txt") { LPVOID data = NULL; hFile = CreateFileA(filename, GENERIC_READ,FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL); if(hFile == INVALID_HANDLE_VALUE) MessageBox(NULL, L"Failed to CreateFile - 'hFile'", L"CDECK::CDECK()", MB_OK); DWORD fileSize = GetFileSize(hFile, &fileSize); DWORD read = -1; if(!ReadFile(hFile, data, fileSize, &read, NULL)) { DWORD err = GetLastError(); MessageBox(NULL, L"Failed to ReadFile - 'hFile'", L"CDECK::CDECK()", MB_OK); } return; } ```
