Can't get external program to run

[Jerry Spence]

In MT4 this worked OK:

#import "shell32.dll"

int ShellExecuteA(int hWnd,int lpVerb,string lpFile,string lpParameters,int lpDirectory,int nCmdShow);

#import

void OnTick()

{

 ShellExecuteA (0,0,"Notepad.exe","",0,SW_SHOW);

}

When debugging it goes through the ShellExecute command with no error message but I don't get Notepad come up

MQL5 strings are unicode, so you must use unicode version functions (ShellExecuteW)

Hello,

I tried to compile the same code but I get an error message as follows :

'SW_SHOW' - undeclared identifier

 Any help appreciated (I use Vista)
