I wanted to insert my data to a specific sheet name based on form input value of "svdate":

Need help. Already 4 days nothing happens. Trying to do a SQLite database search. How to make it so that the listview is not displayed immediately, but only when the user enters a search query? That is, the data from the database was not filtered, but matches appeared in the listview when the user enters a request. I am very grateful to everyone in advance!`

I'm new to Python. I have a dictionary where some fields are dates ( datetime.datetime type) and I need to use comprehension to convert those to MM/DD/YYYY strings in a new cloned dictionary.

I have a dataframe as below:

I want to have my reference counted C++ object also managed in Lua callbacks: when it is held by a Lua variable, increase its refcount; and when the Lua variable is destroyed, release one refcount. It seems the releasing side can be automatically performed by __gc meta-method, but how to implement the increasing side?

Is it proper&enough to just increase refcount every time before adding the object to Lua stack?

Or maybe I should new a smart pointer object, use it everywhere in Lua C function, then delete it in __gc meta-method? This seems ugly as if something wrong with the Lua execution and the __gc is not called, the newed smart pointer object will be leaked, and the refcounted object it is referring would have leak one count.

In Perl that I'm more familiar with, this can be achieved by increase refcount at OUTPUT section of XS Map, and decrease refcount at destroyer.

This code receives information from an acquaintance you want to register in editText, and then clicks finButton to save the information you receive as a file called friendlist.txt. However, the Toast message is outputted from the try-catch statement that is currently performed when finButton is pressed. Also, the checkpermission does not work, which is wrapped in a try~catch statement, but does not have output on the logcat.

And manifest.

uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"

uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"

is written.

Please let me know the solution. And this content is written with a translator, so the sentence can be strange.

when you press finButton, the logcat is shown below.

The code corresponding to the 116th line is this.

FileOutputStream outstream = openFileOutput("friendList.txt", Activity.MODE_WORLD_WRITEABLE);

I have a dynamic query that adds WHERE clauses according to the parameters received:
