QUESTION
I've been trying to add another sendasmail alias from sometimes visa app scripts but the endpoint doesn't seem to work or I'm not sure if that's the intended behavior of it.
This is the endpoint https://gmail.googleapis.com/gmail/v1/users/%s/settings/sendAs/%s',getEmail, "007@alias.domain.com"
that I'm using.
Here's the AppScipt Code along with payload which I'm trying to use.
...ANSWER
Answered 2021-Jun-11 at 14:04- When you make a
PUT
request to the https://gmail.googleapis.com/gmail/v1/users/{userId}/settings/sendAs/{sendAsEmail} endpoint, you can update an already existing alias - Thereby, you need to specify the new
{ "sendAsEmail": "" }
in the request body and the oldsendAs
in the request URL - If instead you want to create a new, non-existing alias, you need to make a
POST
request to the https://gmail.googleapis.com/gmail/v1/users/{userId}/settings/sendAs endpoint

I am trying to map out payment method objects that I receive from my server into an array of dictionaries. So far I have been able to get individual dictionaries but I haven't been able to put them into an array.
This is my struct that I want to use to map out the data:
...ANSWER
Answered 2021-May-26 at 17:20To reiterate the comments:
The issue here is that in the line self.paymentMethods = data.map({ (card) -> PaymentMethod in ...
, the card is not a card ([String:Any]
), but a whole data-object with a lot of information. So to fix this issue you simply have to get the card
from the data
-object like so:

I am trying to list all of my user's payment methods. I am mainly trying to get the brand, expiration date, and last 4 digits of the credit card number.
I've tried multiple ways to parse the JSON payment method object being sent back from my server but I haven't been successful yet. This is what I did in the latest attempt I made.
In my server I get a list of all my user's payment methods and send back the raw data to my client using this function:

QUESTION
I just got into C programming and learning in CS50. I was trying to convert the char
generated from the card number into an integer that I can sum with. Basically, I'm looking for an equivalent for Java's charAt()
in C.

is for converting strings (sequences of characters terminated by a null-character) to integers, not for converting characters.
To convert decimal characters to corresponding integer, you can subtract '0'
(the character code for the characer 0
because character code of decimal characters are defined to be continuous in the C specification.
In conculsion, you should replace the two atoi(cardNumber[i])
s to (cardNumber[i] - '0')
.
QUESTION
I have a dataframe where there two instances of a value in each row (say the value is 34). I would like to replace one instance with 3 and the other with 4 (without replament, so if the first instance gets 4, the second instance gets 3. And visa versa.) And I would like to do the assignments randomly (so that some rows use 3 then 4, other rows 4 then 3.)
Here's my example:
...ANSWER
Answered 2021-May-18 at 14:55You can just loop over all columns and for each column create a boolean random vector that has about as many TRUE as FALSE values.
Then, you just replace the 34
for TRUE values with 3 and the rest with 4.
QUESTION
I am trying to create a LabVIEW DLL and call it from a C++ program but I am facing a problem of data passing.
A scientific camera I recently bought comes with a LabVIEW SDK, and nothing else. The example program provided with the SDK is mainly a while loop around two functions, ReadData and DecodeData.
- ReadData collects data from USB (using VISA read), the data obtained in one call contains several complete data blocks and an incomplete incoming block.
- DecodeData is called multiple times to process all the complete blocks (it removes the processed data from the buffer). When all the complete blocks have been processed, the remaining data (the beginning of the incoming block) is passed to ReadData which will concatenate its new data at the end of the buffer.
In the example program, written in LabVIEW, everything works fine. The problem is when I export these functions in a DLL. The memory buffers, inputs and outputs of both functions, are char arrays. After ReadData, my C++ program correctly obtains a buffer containg data, including null bytes.
The problem is when I inject this buffer in DecodeData, it seems that LabVIEW only takes into account the bytes before the first null byte... I guess that the char[] input is just processed as a null-terminated string and the rest of the data is just discarded.
I tried to add data converters ("string to byte array" at outputs and "byte array to string" at inputs) but the conversion function also discards the data after the first null character.
I could modify the .vi from the sdk to only handle byte arrays and not strings, but it uses lots of character processing functions and I would prefer leaving it as is.
How can I pass the data buffer from C++ to the LabVIEW DLL without losing part of my data?
Edit: here is the C++ code.
The header exported with the LabVIEW DLL:
...ANSWER
Answered 2021-May-16 at 17:11It is a little tricky to answer in this specific case but assuming that the problem is that NULL values in the buffer data are causing issues then it might be worth looking at the option to use String Handle Pointers for the String-Type controls and indicators of the VIs you are exporting.
This option can be selected during the "Define VI Prototype" stage of configuring the DLL Build
LabVIEW manages String Types internally as an integer of the string's length and an unsigned char array so it shouldn't matter what characters are used. For interfacing with external code, LabVIEW's extcode.h
header defines an LStrHandle
