I work for the first time with the Dotnet.Highcharts framework in Visual Basic and I need your help.
I want to set the tickpositions, but I do not know how.
code snippet:
.SetYAxis(New YAxis With {.GridLineWidth = 0, _
.Title = New YAxisTitle With {.Text = "test text"}, _
.Min = 1, _
.Max = 3, _
.TickPositions = ??? })
Thanks for help
The TickPositions property of the YAxis class is of type Number?() which is an array of a specific Highcharts type to represent numbers
There are implicit conversion operators in the code for Number from int, double, and nullable ints and doubles, as well as constructors, so defining an array of them can be as easy as:
Dim tickPositions as Number?() = New Number?() {1, 2.5, new Number(123)}
or in your inline code:
.TickPositions = New Number?() {1, 2.5, new Number(123)} })

By using the Godot engine and writing in the GDScript language,
let's say I have an enum declared as:
enum eTextMode {CHAR, NUMBER, SYMBOLS_TEXT, SYMBOLS_ALL}
And an export variable as:
export(eTextMode, FLAGS) var _id: int = 0
In the inspector panel I can see which flag is selected or not, but how can I know in code which specifically flag is selected?
By selecting in the inspector, for example: the NUMBER and SYMBOLS_TEXT flags, the _id variable will be set as 5
My approach is the following hard-coded dictionary:
var _selected_flags: Dictionary = {
CHAR = _id in [1, 3, 5, 7, 9, 11, 13, 15],
NUMBER = _id in [2, 3, 6, 7, 10, 11, 14, 15],
SYMBOLS_TEXT = _id in [4, 5, 6, 7, 12, 13, 14, 15],
SYMBOLS_ALL = _id in [8, 9, 10, 11, 12, 13, 14, 15]
}
Resulting in:
{CHAR:True, NUMBER:False, SYMBOLS_ALL:False, SYMBOLS_TEXT:True}
The above result is exactly what I'm expecting (a dictionary with string keys as they are defined in the enum with a boolean value representing the selection state).
How could I manage to do this dynamically for any enum regardless of size?
Thank you very much,
One tacky solution that I could manage is by not using an enum at all, but instead a dictionary like the following example:
const dTextMode: Dictionary = {CHAR = false, NUMBER = false, SYMBOLS_TEXT = false, SYMBOLS_ALL = false}
export(Dictionary) var m_dTextMode: Dictionary = dTextMode setget Set_TextMode, Get_TextMode
func Get_TextMode() -> Dictionary: return m_dTextMode
func Set_TextMode(_data: Dictionary = m_dTextMode) -> void: m_dTextMode = _data
An exported dictionary is not as good-looking as an exported enum with FLAGS, and by following this approach it kind of invalidates my initial problem.
By selecting CHAR and SYMBOLS_TEXT in the exported dictionary from the inspector, and then calling print(self.Get_TextMode()) the result is indeed what I expected:
{CHAR:True, NUMBER:False, SYMBOLS_ALL:False, SYMBOLS_TEXT:True}
I still can't figure out though how to achieve this result by using the export(*enum, FLAGS) aproach.
Edit: also, the setter function is not feasible to be used in script since the user must know to duplicate the dTextMode constant first, edit it and set is as an argument.
Thanks to the comments from #Thearot from my first answer, I have managed to figure out the following solution which meets all expectations, with one caveat: it seems like an overkill solution...
enum eTestFlags {FLAG_1, FLAG_2, FLAG_3, FLAG_5, FLAG_6}
export(eTestFlags, FLAGS) var m_iTestFlags: int = 0 setget Set_TestFlags
func Get_TestFlags() -> Dictionary: return self._get_enum_flags(m_iTestFlags, eTestFlags)
func Set_TestFlags(_id: int = m_iTestFlags) -> void: m_iTestFlags = _id
func _get_enum_flags(_val_selected: int, _enum: Dictionary, _bit_check_limit: int = 32) -> Dictionary:
var _enum_keys: Array = _enum.keys() ; _enum_keys.invert()
var _bin_string: String = ""
var _val_temp: int = 0
var _val_count: int = _bit_check_limit - int(_is_pow2(_bit_check_limit))
while(_val_count >= 0):
_val_temp = _val_selected >> _val_count
_bin_string += "1" if _val_temp & 1 else "0"
_val_count -= 1
var _bin_string_padded: String = "%0*d" % [_enum_keys.size(), int(_bin_string)]
var _result_dict: Dictionary = {}
for _str_id in range(_bin_string_padded.length(), 0, -1):
_result_dict[_enum_keys[_str_id - 1]] = bool(_bin_string_padded[_str_id - 1] == "1")
return _result_dict
func _is_pow2(_value: int) -> bool:
return _value && (not (_value & (_value - 1)))
Now, if I print(self.Get_TestFlags()) after selecting FLAG_2 and FLAG_6 the result is:
{FLAG_1:False, FLAG_2:True, FLAG_3:False, FLAG_5:False, FLAG_6:True}
You're on the right track but overcomplicating things. Without going too much into the math (see Wikipedia), here's what you'd do in Godot:
enum eTextMode {CHAR, NUMBER, SYMBOLS_TEXT, SYMBOLS_ALL}
export(eTextMode, FLAGS) var _id: int = 0
func _ready() -> void:
for modeName in eTextMode:
var bit_flag_value: int = int(pow(2, eTextMode[modeName]))
if _id & bit_flag_value:
printt("Flagged", modeName)
You can access the named fields of your enum like elements in an Array/Dictionary by default (iterate through the keys, get their 0-based index as values). The above math trick turns the 0-based index into the correct bit flag number, and if you (single) '&' it with the combined bit-flags value you can check whether or not that flag is set.
I need to help to port my 3.5 rc.lua to 4.0. I try to set one progressbar.
It used to be :
mybacklight = awful.widget.progressbar()
mybacklight:set_width(12)
mybacklight:set_height(10)
mybacklight:set_vertical(true)
mybacklight:set_background_color("#131211")
mybacklight:set_border_color(nil)
The new version should be :
mybacklight = wibox.widget.progressbar {
max_value = 1,
value = brightness_new,
forced_width = 12,
forced_height = 10,
background_color = "#131211",
border_color = nil,
color = {type="linear", from = {0, 0}, to = {0, 20},
stops = { {0, "#F6F6F6"}, {0.5,
"#bdbdbd"}, {1.0, "#3b3b3b"} } },
widget = wibox.widget.progressbar,
direction = 'east',
layout = wibox.container.rotate
}
The 3.5 version works (no errors) but does no more give the expected result, it should be a vertical progressbar, it is, but the progression itself is horizontal.
The 4.0 version makes no error, except that it takes all the place with red (default ?) colors.
First of all, the imperative syntax isn't gone, you can still do it "the old way". It is fully supported and the declarative one is "compiled to" the old one.
Now, to answer the question, the code should look like (untested):
mybacklight = wibox.widget {
{
max_value = 1,
value = brightness_new,
background_color = "#131211",
color = {type="linear", from = {0, 0}, to = {0, 20},
stops = { {0, "#F6F6F6"}, {0.5,
"#bdbdbd"}, {1.0, "#3b3b3b"} }
},
widget = wibox.widget.progressbar,
},
forced_width = 12,
forced_height = 10,
direction = 'east',
layout = wibox.container.rotate
}
Changes:
The composite widget constructor is wibox.widget. You used the progressbar constructor to contruct a rotate container
Indentation to make the code more readable
You had 2 widget in the same block, this isn't supported.

I have written a code in ASP.NET to fetch data from Oracle stored procedure. But I get an error when trying to fetch the data:
ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'USER_FEEDBACK' ORA-06550: line 1, column 7: PL/SQL: Statement ignored
Procedure code is this:
create or replace PROCEDURE user_feedback(cv_results out sys_refcursor,start_date IN VARCHAR2)
IS
BEGIN
open cv_results for
select pi.first_name || ' ' || pi.last_name initiator
......
from request_workflow w inner join request_workflow_attribute waRating
on waRating.request_workflow_id = w.row_id
and waRating.attr_name = 'UserRating'
.............
where w.date_stamp_utc between start_date and '31-dec-2015'
order by waRating.attr_value desc, eform_name;
END ;
This is my ASP.NET code:
Oracle.DataAccess.Client.OracleCommand objCmd = new Oracle.DataAccess.Client.OracleCommand();
objCmd.Connection = objConn;
objCmd.CommandText = "user_feedback";
objCmd.CommandType = CommandType.StoredProcedure;
Oracle.DataAccess.Client.OracleParameter oraP = new Oracle.DataAccess.Client.OracleParameter();
// System.Data.OracleClient.OracleParameter op = null;
oraP.OracleDbType = OracleDbType.RefCursor;
oraP.ParameterName = "cv_results";
oraP.Direction = System.Data.ParameterDirection.Output;
oraP.ParameterName = "start_date";
oraP.OracleDbType = OracleDbType.Varchar2;
oraP.Value = "01-Dec-2015";
oraP.Direction = System.Data.ParameterDirection.Input;
objCmd.Parameters.Add(oraP);
objConn.Open();
objCmd.ExecuteReader();
objCmd.ExecuteNonQuery();
Please suggest how to make it work.
You're only creating/adding a single parameter but assigning it twice with different values resulting in just one parameter to the call.
Instead, create and add two separate parameters, something like;
var oraP1 = new Oracle.DataAccess.Client.OracleParameter();
oraP1.OracleDbType = OracleDbType.RefCursor;
oraP1.ParameterName = "cv_results";
oraP1.Direction = System.Data.ParameterDirection.Output;
objCmd.Parameters.Add(oraP1);
var oraP2 = new Oracle.DataAccess.Client.OracleParameter();
oraP2.ParameterName = "start_date";
oraP2.OracleDbType = OracleDbType.Varchar2;
oraP2.Value = "01-Dec-2015";
oraP2.Direction = System.Data.ParameterDirection.Input;
objCmd.Parameters.Add(oraP2);
It's probably because you don't Add the first parameter. Try something like this?
...
oraP.ParameterName = "cv_results";
oraP.Direction = System.Data.ParameterDirection.Output;
objCmd.Parameters.Add(oraP);
oraP = new Oracle.DataAccess.Client.OracleParameter();
oraP.ParameterName = "start_date";
...
Though, it'd be better to declare another variable for the first param if you'll be reading from that refcursor later.
I am trying to convert an array of strings in unityscript with values holding values like:
"Vector3(5, 3, 8)"
into an array of vectors, but Unity will not take these strings as is. Anyone have any ideas?
you cant convert all vector elements together in c# you can do it like bellow:
its psuedoCode:
position.x=convert.ToFloat("3");
position.y=....
i think there is no api to make this for you:
"Vector3(5, 3, 8)"
You didn't give us any sample code, so I'll assume the array is nicely organized, all elements right next to each other.
While I don't think there's any way that you can do this fully using UnityScript, there's ways you can process the literal string with other languages, that is, copying from your Unity script and into another program that will do the change for you.
Here's a small sample of what I would do.
Usage: Create a file array.txt with all the Vector3(x,x,x) strings, separated by line breaks and create another file array.php
Array.txt (sample)
Vector3(5, 1, 3)
Vector3(3, 3, 1)
Vector3(2, 2, 7)
Vector3(6, 6, 4)
Vector3(8, 8, 8)
Vector3(9, 3, 2)
Vector3(1, 2, 1)
Vector3(4, 3, 6)
Vector3(5, 3, 8)
Array.php
<?
$file = file('array.txt');
$text = array();
$text[] = "var vectors = new Array;";
foreach ( $file as $i )
{
$text[] = "vectors.Push(".trim($i).");";
}
echo implode("<br>", $text);
Then just run it under a PHP sandbox or a web server and copy and paste the new array into your script.
use this method to convert a single String value into a vector3 value
public static Vector3 StringToVector3(string sVector)
{
// Remove the parentheses
if (sVector.StartsWith ("(") && sVector.EndsWith (")")) {
sVector = sVector.Substring(1, sVector.Length-2);
}
// split the items
string[] sArray = sVector.Split(',');
// store as a Vector3
Vector3 result = new Vector3(
float.Parse(sArray[0]),
float.Parse(sArray[1]),
float.Parse(sArray[2]));
return result;
}
I figure someone else might find this useful later so:
if(PlayerPrefs.GetFloat("nodeNum") > 0) {
//Assemble axis value arrays
//X
var xString = PlayerPrefs.GetString("xVals");
var xValues = xString.Split(","[0]);
//Y
var yString = PlayerPrefs.GetString("yVals");
var yValues = yString.Split(","[0]);
//Z
var zString = PlayerPrefs.GetString("zVals");
var zValues = zString.Split(","[0]);
var countNode = 0;
var goal = PlayerPrefs.GetFloat("nodeNum");
var nodeVecs = new Array(Vector3.zero);
while (countNode != goal) {
var curVec = Vector3(float.Parse(xValues[countNode]), float.Parse(yValues[countNode]), float.Parse(zValues[countNode]));
nodeVecs.Push(curVec);
countNode += 1;
}
var convNodeVecs : Vector3[] = nodeVecs.ToBuiltin(Vector3) as Vector3[];
for(var nodeVec : Vector3 in convNodeVecs) {
Instantiate(nodeObj, nodeVec, Quaternion.identity);
}
}
I am Developing a web apps in Asp.net using vb.net language and i comparing two string using
"=" and
"String.Equals()"
but i get always false result
Dim decod As Decoder = Encoding.UTF8.GetDecoder()
Dim totByt As Byte() = Convert.FromBase64String(Request("numType"))
Dim chrCount As Integer = decod.GetCharCount(totByt, 0, totByt.Length)
Dim deco_char(chrCount) As Char
decod.GetChars(totByt, 0, totByt.Length, deco_char, 0)
Dim str As New String(deco_char)
If str = "MO" Or str.Equals("Mo") Then
//Do somthing
End If
Please see my Watch window output
Please tell me why this give me false condition and how to solve it.
Check out the documentation for String.Equals() and look at the possible values for 3rd parameter comparisionType
String.Equals("MO", str, StringComparison.OrdinalIgnoreCase))
The str variable has a length of 3, instead of 2, causing it to be different than "MO".
Proof:
Dim decod As Decoder = Encoding.UTF8.GetDecoder()
Dim totByt As Byte() = Convert.FromBase64String("TU8=")
Dim chrCount As Integer = decod.GetCharCount(totByt, 0, totByt.Length)
Dim deco_char(chrCount) As Char
decod.GetChars(totByt, 0, totByt.Length, deco_char, 0)
Dim str As New String(deco_char)
Dim result1 = str.StartsWith("MO") ' is true
Dim result2 = str.Equals("MO") ' is false
Dim length = str.Length ' is 3
So obviously str is not the same as "MO".
Remember that if you declare an array like:
Dim deco_char(2) ' an array of 3 elements
...the indexes of the elements range from 0 through 2, so it contains 3 elements.
Solution: if you replace line 4 with:
Dim deco_char(chrCount-1) As Char
.. it will work, because now (in your specific case) your array is of size 2 instead of 3.
Try this :
str.Equals("MO", StringComparison.CurrentCultureIgnoreCase);
