The Service on local computer started and then stopped ,Some services stop automatically if there are not in use by other services or programs

In my case, the windows service was working fine on Local, but while deploying on another machine. I created the service using SC commands which was done successfully, but on starting the service, I got this error.

Solution that worked for me:
1) On my local computer, cleared the data of Debug and Release folders in both bin and obj directories.

2) Then deployed, created and started the service successfully.

Run multiple SQL scripts in order using a batch file

Suppose, we have to run following sql files in the order:


1) CREATE_TABLES.sql
2) TABLE_INSERTS.sql
3) CREATE_INDEXES.sql
4) CREATE_PROCEDURES.sql

and suppose they are all present in the directory:
C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck


Now, create a script say CREATE_DB.sql 

SET NOCOUNT ON
GO

PRINT 'CREATING DATABASE'
IF EXISTS (SELECT 1 FROM SYS.DATABASES WHERE NAME = 'HELLODB')
DROP DATABASE HELLODB
GO
CREATE DATABASE HELLODB
GO

USE HELLODB
GO
:On Error exit

:r "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\CREATE_TABLES.sql"
:r "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\TABLE_INSERTS.sql"
:r "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\CREATE_INDEXES.sql"
:r "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\CREATE_PROCEDURES.sql"

PRINT 'DATABASE CREATE IS COMPLETE'
GO

If HELLODB already exists and you don't want to drop it, then remove the highlighted code above.

Now, create a new file, add the following code and save as demo.bat:

if HELLODB already exists:

SQLCMD -E -d HELLODB -i "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\create_db.sql"
PAUSE

if HELLODB does not exist:

SQLCMD -E -d master -i "C:\Users\Arjun\Documents\SQL Server Management Studio\BATCheck\create_db.sql"
PAUSE

Now, double click the demo.bat file and all the sql scripts will get executed.

warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] in COBOL

I recently installed Open-COBOL in Ubuntu. I wrote a program helloworld.cbl and compiled it using command:

cobc -free -x -o helloworld helloworld.cbl

After compiling the code, I got a bunch of warnings all of which looks like:

warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

Solution:
To get rid of the warnings, compile the code using command:
     cobc -free -x -O -o helloworld helloworld.cbl

Error: syntax error, unexpected "end of file" in COBOL

Key Point:
Each line should end with CRLF (Carriage Return + Line Feed). It means each line should end with '\r\n'.

Solution:
To get rid of the error, copy-paste the code in Notepad++ and do the following steps:

1) Replace '\n' with '' (blank).
2) Replace '\r' with '\r\n'
3) Go to the last line and hit Enter.
