Need Help In Opening a URL in Browser From MT5 (MQL5)

[Kailash Bai Mina]

Currently I am Using the Below Code In MQL4,

//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
bool openURL(string url){
    int APPEND  = FILE_CSV|FILE_WRITE;
    string  file = WindowExpertName() + ".URL";
    int handle   = FileOpen(file, APPEND, '~');
    if (handle < 1){ int GLE = GetLastError();Print("Last Error Code: "+(string)GLE);ResetLastError();}
    FileWrite(handle, "[InternetShortcut]");
    FileWrite(handle, "URL="+url);
    FileClose(handle);
    return ( Shell(TerminalInfoString(TERMINAL_DATA_PATH)+"\\MQL4\\Files\\"+file) );      // or "cmd.exe", "/C "+file
}
#import "shell32.dll"
   int ShellExecuteW(int hWnd, string Verb, string File, string Parameter, string Path, int ShowCmd);
#import
bool Shell(string file, string parameters=""){
    #define DEFDIRECTORY NULL
    #define OPERATION "open"    // or print
    #define SW_SHOWNORMAL 1
    int r=ShellExecuteW(0, OPERATION, file, parameters, DEFDIRECTORY, SW_SHOWNORMAL);
    if (r > 32) return(true);
    //Alert("Shell failed: ",r);
    return(false);
}
//+------------------------------------------------------------------+

This Work Perfectlly In MQL4.

I don't know anything about these dll and advanced stuff (Can Someone Also Suggest How To Learn About these Advanced Things?).
I just copied this code from a MQL4 forum.

I have tried to use it in MT5 (Of course after removing few error caused due to migration to MQL5)
But It Doesn't Work.

Can Someone Help Me With MQL5 Version Of This?

I am a  first timer in this community of business and I'm bit nervous of losing everything at the end of the day,something would be encouragable regarding a  platform suitable either to set a pase for me, otherwise I'm pleased to participate as agreed.  thank you.

    string  file = MQLInfoString(MQL_PROGRAM_NAME) + ".URL";
    int handle   = FileOpen(file, APPEND, '~');
    if (handle < 1){ int GLE = GetLastError();Print("Last Error Code: "+(string)GLE);ResetLastError();}
    FileWrite(handle, "[InternetShortcut]");
    FileWrite(handle, "URL="+url);
    FileClose(handle);
    return(Shell(TerminalInfoString(TERMINAL_DATA_PATH)+"\\MQL5\\Files\\"+file));     // or "cmd.exe", "/C "+file
}

Thanks.

Can You Please Tell Where can i learn Deeply about these advanced things?

1. Path is wrong per Ernst.
2. MT5 is a 64 bit application. Perhaps you can use the 64 bit one.
   

   On a 64 bit system,, the 64 bit shell32.dll is in the System32 directory and the 32 bit shell32.dll is in the SysWOW64 directory.
             Shell32 in 64 bit?

Paying forward and helping out others, here is the version that is tested and works for MT5, after putting together the comments from the messages above. Thanks everyone !

Small observation - I found this line does not compile in MQL5:

    string  file = WindowExpertName() + ".URL";

I changed it after which it compiled 

    string  file = __FILE__ + ".URL";

Also had to change MQL4 to MQL5 but it worked after that - nicely done!

    return ( Shell(TerminalInfoString(TERMINAL_DATA_PATH)+"\\MQL5\\Files\\"+file) );      // or "cmd.exe", "/C "+file

Very simple, Mt4 Open url , 

Shell32::ShellExecuteW

Mt5 Open Url

int r=ShellExecuteW

#import "shell32.dll"
int ShellExecuteW(int hwnd, string Operation, string File, string Parameters, string Directory, int ShowCmd);
#import


int r=ShellExecuteW(0, "open", "www.mql5.com", "", "", 3); // Mql5


//Shell32::ShellExecuteW(0, "open", "www.mql5.com", "", "", 3); // Old Model mql4
