Powershell with Literal Path

When folder name has [], you can escape them with two back tick “ to escape them to create a file by using the path with special characters.

  
  
 
 
 
New-Item  –Path "c:temp\``[Profile Backup``]\$(Get-Date -Format yyyy_MM_dd)\" -Name "Installed_Programs1.txt" -ItemType File -Force

New-Item  –Path "c:temp\``[Profile Backup``]\2017_03_17\" -Name "Installed_Programs1.txt" -ItemType File -Force
 
 
 ##create the folder(don't need escape), then create the file
md -Path "c:temp\[Profile Backup]\$(Get-Date -Format yyyy_MM_dd)" -Force
New-Item  –Path "c:temp\``[Profile Backup``]\$(Get-Date -Format yyyy_MM_dd)\" -Name "Installed_Programs1.txt" -ItemType File -Force

WASP Bar Code Reader (MCS 3950) Unofficial Setting to Read One Digit

By default, WASP Barcode ReaderWCS 3950 does not support 1 digit with Code128 barcode based on its User Manual.

But I found a link to have a workaround:
http://support.waspbarcode.com/index.php?/Knowledgebase/Article/View/884/74/program-the–wlr2900-wcs3900-and-wlr8900-series-scanners-to-read-pre-printed-barcodes

A link titled as “Code 128 Minimum Length Programming Sheet” has barcode sources to update scanner setting.

The source barcode for Minimum Length barcode, 0 barcode and 1 barcode was downloaded from below link:
http://dl.waspbarcode.com/wasp/supportfiles/WLR2900,WCS3900,WLR8900MinLength.pdf
After print this PDF page and do the following
1. Scan the Minimum Length barcode (Code 128).
2. Scan the 0 barcode then the 1 barcode.
3. Scan the Minimum Length barcode again.

You should be able to scan one digit barcode generated with code 128 now.


Export Flat File from SQL Server for AS400 System to Consume (with Code page 65001(UTF-8) )

I have a client request for a csv file from our system to consume in their AS400 system.

The request was side-tracked by to remove the last non-visible line at the end of the file.

The real problem is the encoding issue. The default encoding from our Windows (2012) system is 1252(ANSI -Latin I).
First I tried Code Page 437 but it didn’t work.

Finally I switched the encoding to Code page 650001(UTF-8) from the Flat File Connection Manager,
and it seems the file works in the third party environments.

Export Flat File Without Header in SSIS Package

When export flat file through bcp, it will take some efforts to add the header row.
This is very easy to hide it from SSIS Flat File Connection.
In SSIS package, we can define a property from Flat File Connection to set “ColumnNamesInFirstDataRow” to “False”.
The result flat file will have data only without hearder row.
