import std.c.stdio;
import std.string;


extern(C) int strlen(char* c);

extern(Windows) 
{
    DWORD GetModuleFileNameA(HMODULE hModule, LPSTR lpFilename, DWORD nSize);   
    HMODULE GetModuleHandleA(LPCSTR lpModuleName);
}


char[] AppExePath()
{
    /* returns the Path to the current .exe module (e.g. "F:\PGM\D\TRAYICON\") */

    char[] strtmp;
    strtmp.length = 1024;

    GetModuleFileNameA(GetModuleHandleA(null), cast(char*) strtmp.ptr, 1024);
    int j = rfind(strtmp[0..strlen(strtmp.ptr)], "\\");

    strtmp = strtmp[0..j+1];
    return strtmp;
}


void main()
{  
    printf("%.*s\n", AppExePath);    
}
