excel - Argument not optional error when returning dictionary -

-

i have following code in vba , i'm trying capture dictionary object returned first function parents in line says "set parents = parents()" keep getting argument not optional error.

everyone on internet says it's because set keyword missing in case isn't. appreciated, thanks!

public function parents() dictionary     dim filenum integer     dim dataline string     dim filepath string     set parents = new dictionary       filepath = application.activeworkbook.path & "\parents.txt"      filenum = freefile()     open filepath input #filenum      while not eof(filenum)         line input #filenum, dataline         parents.add dataline, 1     wend end function  public sub computechanges()     .     .     dim parents dictionary, adjustments dictionary, inner dictionary, changes dictionary     set parents = parents()     .     . end sub

i suggest changing function sub , passing pre-declared dictionary object in parameter.

public sub constructparents(dprnts dictionary)      dprnts.removeall     dprnts.comparemode = textcompare      dprnts.add key:="joe & jill", item:=100     dprnts.add key:="sam & sally", item:=200     dprnts.add key:="dave & debbie", item:=300     dprnts.add key:="bob & jane", item:=400     debug.print dprnts.count  end sub  public sub computechanges()      dim dparents new dictionary, vkey variant      constructparents dparents     'optionally use if makes more sense     'call constructparents(dparents)      each vkey in dparents         debug.print "key: " & vkey & ", item: " & dparents.item(vkey)     next vkey  end sub

i've simplified code in order did not have duplicate environment hope can transcribe method own purposes.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
