filter wizard returning unknown error
uipath throws me the following error:

worked around it with excel vba as uipath didnt work
hi chris, 
if you use relations api, you may set properties field in your query. in this field you should set the names of the properties which values must be retrieved from the server. the argument should be a string in the following format: "propertyname1, propertyname2, , , propertynamen" , wher… Did you bind the listBox1, using DataSource property from DataTable?  

If so, you have to 1st get the item and value from listBox item and add it some other place (in your case to listBox2):



```
for(int i = 0; i < listBox1.SelectedItems.Count; i++)
{
     DataRowView view = listBox1.SelectedItem as DataRowView;
     string item = view["ColumnNameOfItem"].ToString(); //can be some name
     int value = Convert.ToInt32(view["ColumnNameOfValue"]);  //can be some id (number)
     listBox2.Items.Add(item); // it you want to add item (you can add value as well);
}
```

ColumnNameOfItem (or OfValue) are the names of fields in your dataTable (and same are in dataBase as well). Insteads of names you can use indexes (0 and 1, but without quotation marks).



Hope it helps.  

bye A few things to try.


1. Use [Variable Tables](http://odetocode.com/Articles/365.aspx) instead -> maybe the import wizard prefers that?
2. Name your return fields.


Try using the following stored proc (untested .. just thinking out loud...)



```
CREATE PROCEDURE dbo.Foo
AS

    SET NOCOUNT ON

    DECLARE @ResultTable TABLE (SomeId INTEGER)

    INSERT INTO @ResultTable
    SELECT DISTINCT Id AS Identity -- Or u can rename this field to anything...
    FROM SomeExistingTableWhichHasAnIdentityField

GO

```

Try that and see if the wizard refreshes, now.

 Attempt #2 :)


Ok .. when the EF designer/wizard/whatever fails to figure out EXACTLY what my stored proc is suppose to be returning, I usually do the following :-


1. Make sure the stored procedure doesn't exist at all in the EF designer/context, etc. (You have a clean starting point)
2. Open up your stored procedure and `/* /*` comment out *EVERYTHING* after the procedure definition.


eg..



```
ALTER PROCEDURE dbo.Foo
(
    Bar1 INT,
    Bar2 TINYINT,
    ... // whatever u have as your optional input arguments //
)
AS
    SET NOCOUNT ON

    /* 
    .... every thing in here is commented out 
    */
GO

```

Now ...
 3. Add a forced fake return in the stored proc, which (more or less) just *defines* the output structure/fields.


eg..



```
ALTER PROCEDURE dbo.Foo
(
    Bar1 INT,
    Bar2 TINYINT,
    ... // whatever u have as your optional input arguments //
)
AS
    SET NOCOUNT ON

    SELECT 1 AS Id, 1 AS UserId, 1 AS SomeOtherId, 
        CAST('AAA' AS NVARCHAR(350)) AS Name,
        -- etc etc etc..
    /* 
    .... every thing in here is commented out 
    */
GO

```

[and then](http://www.youtube.com/watch?v=K7luMp6lb9M) ...


4. Add this stored proc to your EF designer/wizard/etc... Now the correct fields should be 'determined' by the designer. AWESOME. Yes .. the values are all hardcoded .. but that's ok (so far).
5. Once your happy that EF is now updated right, go back to your stored proc, and remove all hardcoded SELECT (which we did in the above step). Now we remove the comments which we commented out the entire real code. So you should have your original stored proc, back.


... and now EF is updated and doesn't know we've changed the plumbing of your stored proc.


win :)


does this work for ya? If I am not wrong, you are trying to read or loop through the rows from datatable. This error states that the datasource(DataTable) is not having any rows. To avoid this exception use this before you read or loop through datatable:  


```
if(dt.Rows.Count  > 0 ){
     //Do your stuff here.
}
```
  

  

  

--Amit So since the line of interest is `newBeautifulKiwi.setKiwi(KIWITextField.getText());` and taking into account that `newBeautifulKiwi` can never be null (it has just been created using default constructor) it's `KIWITextField` that is null and thus not inject properly. make sure the id of this element in .fxml file ***exactly*** matches this field's name (I'd made it private).


Most probable cause is `setSettersLose` annotated with @FXML. Check the [similar thread](https://stackoverflow.com/questions/14017542/how-do-i-change-fxml-controller-variable-values-in-javafx-before-showing-window). hello [@saurabhgupta](/u/saurabhgupta) :wave:

i’m afraid that the last updated column isn’t supported by our api at this time. this is because it’s calculated client side. you can see a list of these column types here - <https://monday.com/developers/v2#column-values-section-auto-calculated-column>

although the api do… you’re on the right track.

is the name column of the choices table of the same column type as the 1st place and 2nd place columns?

please post a screenshot of the error message and the complete expression to which it refers. this is because you have a space between fields. 

program files (x86), avast software, it will continue to get this error because of the separation. try enclosing it into quotations. such as:get-content "c:\program files (x86)\avast software\business agent\log.txt"orget-content "c:\program files (x86)\avast software\business agent"\log.txt Should be able to do something like this:


UPDATE table\_name  

SET new\_column = (calculated value)  

WHERE new\_column is NULL A couple of notes to get started:

Wouldn't this be better as `map`?

`ddf_out` was already a dask dataframe, I don't know why you had to do this.

The value of `result.columns` is taken from the meta you provided, no computing happens until you ask for it (dask is lazy in most operations). Does the ValueError exception not provide further information?


Here is a full example



```
x = ({'F9_07_PZ_COMP_DIRECT': '0',
  'F9_07_PZ_DIRTRSTKEY_NAME': 'DEBRA MEALY',
  'F9_07_PZ_COMP_OTHER': '0',
  'F9_07_PZ_COMP_RELATED': '0',
  'F9_07_PZ_TITLE': 'CHAIR PERSON',
  'F9_07_PZ_AVE_HOURS_WEEK': '1.00',
  'F9_07_PC_TRUSTEE_INDIVIDUAL': 'X'},
 {'F9_07_PZ_COMP_DIRECT': '0',
  'F9_07_PZ_DIRTRSTKEY_NAME': 'HELEN GORDON',
  'F9_07_PZ_COMP_OTHER': '0',
  'F9_07_PZ_COMP_RELATED': '0',
  'F9_07_PZ_TITLE': 'VICE CHAIR',
  'F9_07_PZ_AVE_HOURS_WEEK': '1.00',
  'F9_07_PC_TRUSTEE_INDIVIDUAL': 'X'})
df = pd.DataFrame({'a': x})
d = dd.from_pandas(df, 1)
meta = pd.DataFrame(columns=['F9_07_PZ_COMP_DIRECT', 
       'F9_07_PZ_DIRTRSTKEY_NAME',
       'F9_07_PZ_COMP_OTHER', 'F9_07_PZ_COMP_RELATED', 'F9_07_PZ_TITLE',
       'F9_07_PZ_AVE_HOURS_WEEK', 'F9_07_PC_TRUSTEE_INDIVIDUAL'], dtype="O")
d.map_partitions(lambda df: df.a.apply(pd.Series), meta=meta).compute()

```

How did I know what `meta` to use? I applied the function to the pandas dataframe - you might use a small piece of the dataframe to do this.


Some additional notes:


* it is an anti-pattern to load the data with pandas, pass to dask workers and then gather the whole result back to a pandas (in memory) dataframe, you are very unlikely to see a speedup this way and may incur a lot of overhead. You are better off loading with something like `dd.read_csv`, and aggregating or writing with dask functions too. Only `compute()` on something that will be small or not return anything (because it involves writing the output). The official examples do not use from\_pandas.
* string and dict processing are python methods, and so hold the interpreter lock (GIL) of any python function: threads will not actually run in parallel. To get parallelism, you need to run in processes, which is most easily achieved using <https://docs.dask.org/en/latest/setup/single-distributed.html>
* the distributed scheduler also gives you access to the dashboard, which has a lot of useful information to diagnose how your system is running. You can also configure a lot about its behaviour, in case you have firewall rules you need to obey.
