问题 What kind of statement do I need to check whether or not a SaveAs operation was successful in vba? Sub saveBookAs() wb.SaveAs fileName:="newFile" End Sub 回答1: You don't need a statement to check if the workbook was saved or not :) If the Save As process fails then that line will error out automatically :) Having said that if you want to check if a file exists or not you can always use the DIR function. DIR Returns a String representing the name of a file, directory, or folder that matches a

问题 How can one save a JUNG graph with a custom node and edge? Problem is, till now we have been able to save a JUNG graph of fields with primitive types like integer, string, etc. But the JUNG graph custom node and edge we are working with involves using datatypes like ArrayList and some more complicated datastructures inside the the edge and/or node. I have searched a lot on the web but came across how to save a simple custom node/edge using only int or string or double. Moreover, my aim is not

问题 I have an object that represents the individual tiles of the ground in a game I am programming. I also have a vector holding instances of the object. What is the best way to save this list to a file? I could loop through the vector and save each x,y coordinate and what image the object uses but that seems a little crude. I can use the boost header files but currently have some major problems when I try to build and use the rest of boost. Any suggestions? 回答1: C++ has no inbuilt serialization

问题 I know this is a lot of code but I really need help making it so as long as a user keeps playing (not getting to a sys.quit) the high score saves and can be shown with the highscore func. Ive been working for hours and cant figure this part out. Please and sorry for so much code. Also open to any ways to make it run better or smoother. import pygame, sys, random from time import * from pygame import * from pygame.locals import * scores=[] name=[] def playagain(): print "Would you like to play

问题 I'm creating an app which has several users. I've created an object (user), which holds more details (name, age, custom objects etc). Because I have a custom object, I know it'll be difficult to use shared preferences. What would be the best way to store the users data? I've looked into SQLite, but I can't find a way to save custom objects into SQLite? Any advice would be appreciated. 回答1: You can store objects in using any of the ORM libraries, one I would suggest is ORMLite Use SQlite with

问题 I'm trying to populate a field called 'identification' using the primary key 'id'. However, as you know, there is no way to know what 'id' an objects is going to be before it has been saved. Therefore, stubbornly I did this: def save(self, *args, **kwargs): super(Notifications, self).save(*args, **kwargs) self.identification = str(self.id) Amusingly, this works in console: >>>new = Notifications.objects.create( # some fields to be filled ) >>>new.identification '3' (# or whatever number) but

问题 In Javascript, I'm creating a number of blobs that I want to prompt the user to save as files. At the moment, I'm doing that using URL.createObjectURL , placing the URL in a link, and simulating a click to the link. (Of course I call URL.revokeObjectURL to release the URL so the blob can be discarded after the user saves it.) I have a loop that runs through and does this for each blob I want the user to save. At least on Firefox, triggering the link is an asynchronous operation; I call click(

问题 Im trying to save a contact with data in all available fields. But for some reason not all the data gets saved. Only fields that seem to work are: StructuredName Phone Im Organization Can anyone give me an idea of where my mistake lies? public void saveContact(Context context) { ArrayList<ContentProviderOperation> op_list = new ArrayList<ContentProviderOperation>(); op_list.add(ContentProviderOperation.newInsert(RawContacts.CONTENT_URI) .withValue(RawContacts.ACCOUNT_TYPE, null) .withValue
