Unable to use Shell32.dll on MQL5

New comment
 

I am running on Windows Vista.

The MT5 is run in AppData\Roaming\MetaQuotes\Terminal\725770E6BE34B17A6EB82115D4D83BD3\

Under MQL5\Scripts, I tried to create a script to open notepad via shell32.dll but was unsuccessful.

runNotepad.mq5

#import "shell32.dll"

int ShellExecuteA(int hwnd,string Operation,string File,string Parameters,string Directory,int ShowCmd);

#import


int OnStart()
  {
   ShellExecuteA(0,"Open","C:\windows\notepad.exe","","",SW_SHOW);
   return(0);

  }

Hope to have some advise.

Thank you!

 

Use unicode version  ShellExecuteW

 

mql5 posted # :

Use unicode version  ShellExecuteW

 

 

Also I think you would need double backslash on the path.  

ShellExecuteW(0,"Open","C:\\windows\\notepad.exe","","",SW_SHOW);

And since ShellExecuteW returns a result it would be good practice to check it.

Hi all,

Thank you for the prompt response.

But I still can't make it work in MQL5.

Attached is the source that I am working on.

Hope can have a workable solution.


Thanks!

Hi!

May I know if the patch will be more complete?

I just found out that I cannot run kernel32.dll too.

e.g:

#import "kernel32.dll"

int WinExec(string NameEx, int dwFlags);

#import

WinExec("notepad",0); -- Script run without executing this, and unloaded itself successfully. 

 

Please read MSDN

Runs the specified application.

UINT WINAPI WinExec(
  __in          LPCSTR lpCmdLine,
  __in          UINT uCmdShow
);
