Library for working with files using WinAPI without location limitations.
At present time the read-only mode is implemented. The library will be updated.
- FileUnlimited.mqh, FileUnlimitedConstants.mqh, and StringUtils.mqh must be copied to the terminal_data_folder\MQL5\Include\TheXpert;
- ConstFileUnlimited.mqh library must be copied to the terminal_data_folder\MQL5\Libraries\TheXpert;
- FileUnlimitedTest.mq5 script must be copied to the terminal_data_folder\MQL5\Scripts.
I tried to make class usage as simple as possible.
Example of application (the script):
#include <TheXpert/FileUnlimited.mqh> #include <TheXpert/StringUtils.mqh> #define CP_UTF16 1200 void OnStart() { string name = "TheXpert\\Test.txt"; string path = TerminalInfoString(TERMINAL_DATA_PATH) + "\\MQL5\\Files\\" + name; int hFile = FileOpen(name, FILE_WRITE | FILE_TXT, ' ', CP_UTF16); if (hFile == INVALID_HANDLE) { Print("File not opened."); return; } bool writeBool = false, readBool = true; long writeLong = -4369549, readLong = 0; double writeDouble = -4369549.245, readDouble = 0; datetime writeDatetime = 2596824987, readDatetime = 0; color writeColor = Blue, readColor = White; string writeString = "2r4i6bf4wb9tb69vw", readString = ""; FileWrite(hFile, writeBool); FileWrite(hFile, writeLong); FileWrite(hFile, writeDouble); FileWrite(hFile, writeDatetime); FileWrite(hFile, writeColor); FileWrite(hFile, writeString); FileClose(hFile); // --------------------------------------------- // from here the library for reading is used. // --------------------------------------------- ConstFile* file = OpenConstFile(path); if (CheckPointer(file) != POINTER_INVALID) { file.Read(readBool); Print("readBool = ", readBool); file.Read(readLong); Print("readLong = ", readLong); file.Read(readDouble); Print("readDouble = ", readDouble); file.Read(readDatetime); Print("readDatetime = ", readDatetime); file.Read(readColor); Print("readColor = ", readColor); file.Read(readString); Print("readString = ", readString); delete file; } else { Print("Failed to open ConstFile at path -- ", path); } }
The library operates with Unicode files only, that's why we have CP_UTF16 code page (for some reason it is not available in language constants).
