iterate over spark dataframe column in C#

I am using the microsoft.spark version 1.0.0 to process a parquet file that is received from the network. I have mapped the parquet file into a Dataframe and i am trying to strip the alias from the userid column which is stored as an email address (user testuser is saved as testuser#gmail.com). Can't seem to figure out how to turn Column into an enumerable and there is not built in way to iterate over the column. Any pointers would be helpful
dataframe.WithColumn("alias", ExtractAlias(dataframe["userid"]))
ExtractAlias(Column userID_column){need to iterate over the column to extract out the user alias}

using Microsoft.Spark.Sql;
dataframe.WithColumn("alias", Functions.split(Functions.col("userid"), "#").GetItem(0))

Can number of lines in Word OpenXML Table of Contents be determined

Say a Word Table Of Contents has 8 lines in it, generated by a Table of Contents field in the normal way.
Is it possible, using C# and Microsoft Open XML, to determine how many lines (in this case 8) are in a Table of Contents field in an existing Word document?
I have not found any obvious properties that would give this information.
Thanks,
Jimmy

Selecting the rows of table of ms word file through c#

I have a table which is in ms word .i need to fill the rows with some data through c#.
I was thinking to fill through array or list or some other data sources.
But the challenge is how to select the first row of the table, there are n number of tables is in my word file.

What type of libary are you using ? Try DocX https://docx.codeplex.com/.
It has great table integration. You can use a template file or a file as a template and create a new table. That way you dont need to worry about table indexin. Or you can use text replacement and fill the tables in the template file whit placeholders.

Textbox name cannot start with a number in SSRS2008?

I'm working with SSRS 2008 in some existing reports I have. One of the new requirements is to add a few columns and two of them begins with a number in its header. For example: 170T_Test.
When displaying the data and headers in the Report Viewer all is OK.
HOWEVER, the problem is when exporting to CSV format. Since the headers showed in this format are taken from the textbox property name, I had to put 170T_Test as the name. But, trying to do that the SSRSS 2008 IDE shows the following messages error:
"Specify a valid name. The name cannot contain spaces, and it must
begin with a letter followed by letter, numbers, or the undescore
character (_)"
So, based on all the explained above, is there a way to have the textbox starting with a number? or is it prohibited?
Regards!

It can be achieved in two different ways.
I prefer method 1. It is much better and reuseable.
Method 1:
Step 1
Update your report dataset to include the headers on row 1.
SELECT * FROM
(
SELECT Field1, Field2, 2 as rowOrder
FROM Tables
Where Conditions
UNION ALL
SELECT '170T Test' AS Field1, '180 T$' AS Field2, 1 as rowOrder
) ORDER BY rowOrder
Step 2:
Modify the RSReportServer.config file on Report server to customize CSV export to exclude header.
2012 config file Location: C:\Program Files\Microsoft SQL Server\MSRS11.MSSQLSERVER\Reporting Services\ReportServer
2008 File Location: \Program Files\Microsoft SQL Server\MSSQL.n\Reporting Services\ReportServer
Imp: Make a backup of the RSReportServer.config in case you need to rollback your changes.
Add another entry in <render> section below CSV extension.
<Extension name="CSVNoHeader" Type="Microsoft.ReportingServices.Rendering.DataRenderer.CsvReport,Microsoft.ReportingServices.DataRendering">
<OverrideNames>
<Name Language="en-US">CSV No Header</Name>
</OverrideNames>
<Configuration>
<DeviceInfo>
<NoHeader>true</NoHeader>
</DeviceInfo>
</Configuration>
</Extension>
Save it. Now you have another drop down export option CSV No Header along with CSV, PDF, XML. Users can use this option to extract the data the way they want.
MSDN Link to customize Rendering extension
Method 2:
STEP 1
Same as above
STEP 2
Use URL access and specify the device info for no header

Resources can't start with a number or a reserved word, if you do this, visual studio will automaticly add an underscore '_' in front of your name.
Your problem probably has something to do with this.

Finding a position in a word document to insert a table

I am working on writing some results of a database query into tables in Word. I have already done the code for accessing/creating objects from the results of my query and find myself a little stuck on writing these to a word template given to me. Its essentially a summary document in which i have to insert tables of the data i pulled from the db in the correct position in the document. So for instance, the document has say 4 section headers and under each header, there is some text after which i have to insert a table. One such header can be like:
School Records
Below you will find a table in which all school records will be listed:
So when i go to print my school record data object, i need a way to somehow insert my data in a table format right below the above line in the word document. Can anyone tell me how i can first find the correct position in the doc and then how you create a table in word from c#?

There is an article about how to insert images at specific position in Word document. Maybe it's useful for you to insert table either.

Add bookmark to the word template and then search for the bookmark and replace it with the image/file.
