Removing extra commas from string after using String.Join to convert array to string (C#)


Quick question here. I'm converting an array into a string using
String.Join. A small issue I have is that, in the array some index
positions will be blank. An example is below:


array[1]
= "Firstcolumn"
array[3] = "Thirdcolumn"

By
using String.Join(",", array);, I'll get the following:



Firstcolumn,,Thirdcolumn


Note the extra ,. How can I
remove the extra commas from the string, or ideally not include blank
indices when using String.Join?

I would like to insert data from three different drop downs into my
spreadsheet but I am having several difficulties. There are three drop
downs called cbo_fac1, cbo_fac2 and cbo_fac3.


Here are
the use cases:


Use case 1 - Results in No
preference
being inserted into spreadsheet

/>cbo_fac1 - No preference
cbo_fac2 - No preference />cbo_fac3 - No preference

Use case 2a - Results
in value, , being inserted into spreadsheet. Should just
be value


cbo_fac1 - Value
cbo_fac2 -

My code is below and this is not a homework assignment, just me
learning. Can someone explain to me why my constructors have errors
taking a char array of data during initialization in main and putting
into a string int he constructor class. Also what is the simple way
to copy a string from another string.
Code: class="bbcode_code">#include <iostream>
#include
"Employee.h"
using namespace std;
int main() />{

"Accounting", 47899);

I have embedded a Python interpreter in a C program. Suppose the C
program reads some bytes from a file into a char array and learns
(somehow) that the bytes represent text with a certain encoding (e.g.,
ISO 8859-1, Windows-1252, or UTF-8). How do I decode the contents of
this char array into a Python string?



The Python string should in general be of type
unicode—for instance, a 0x93 in
Windows-1252 encoded input becomes a u'u0201c'.



I have attempted to use PyString_Decode, but it always
fails when there are non-ASCII characters in the string. Here is an
example that fails:



#include <Python.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
char c_string[] = { (char)0x93, 0 };
PyObject *py_string;

Py_Initialize();

py_string = PyString_Decode(c_string, 1, "windows_1252",
"replace");
if (!py_string) {
PyErr_Print();
return 1;
}
return 0;
}


The error message is UnicodeEncodeError: 'ascii' codec can't
encode character u'u201c' in position 0: ordinal not in
range(128)
, which indicates that the ascii
encoding is used even though we specify windows_1252 in
the call to PyString_Decode.



The following code works around the problem by using
PyString_FromString to create a Python string of the
undecoded bytes, then calling its decode method:



#include <Python.h>
#include <stdio.h>

int main(int argc, char *argv[])
{
char c_string[] = { (char)0x93, 0 };
PyObject *raw, *decoded;

Py_Initialize();

raw = PyString_FromString(c_string);
printf("Undecoded: ");
PyObject_Print(raw, stdout, 0);
printf("
");
decoded = PyObject_CallMethod(raw, "decode", "s",
"windows_1252");
Py_DECREF(raw);
printf("Decoded: ");
PyObject_Print(decoded, stdout, 0);
printf("
");
return 0;
}
Web Development

Example: Google's Outstanding Shares are 670,000,000 and this value
is collected in a txt file from Yahoo Finance API using the below
script.



The issue is; that numbers WITH commas or spaces are near
impossible for the text wizard and Excel to delimit when I pull this
txt file into Excel to complete my work.



Ie the delimiter wants to break 670,000,000 into three
separate values AND spread this across three columns which is
a joke and renders my work futile.



Thus: I need the prospective script to bring all numerical strings
that originally contained commas and spaces back to the txt file
WITHOUT such. Ie no commas or no spaces.



So rather than 670,000,000 being brought into the txt file, I need
670000000 so that Excels antiquated delimiter may render the data into
columns properly.



I have asked this question 4 times on here and each time the code
provided by the super user has not worked.
