Fix Internet Explorer Printing Blank Pages

4 de Fevereiro de 2016 – 10:30

I just ran into an issue where three different clients in the same morning reported that Internet Explorer was printing blank pages.  A quick search on Google turned up the following article: http://www.mutterances.com/?p=83.

The problem specifically manifests itself by printing a blank page with a footer (if you haven’t turned them off) displaying the following line: “file:///C:/Users/userprofile/AppData/Local/Temp/Low/randomfilename.htm”.

To fix this issue, you’ll need to bring up a command prompt (but not with elevated permissions) and type the following commands:

mkdir %userprofile%\AppData\Local\Temp\Low
icacls %userprofile%\AppData\Local\Temp\Low /setintegritylevel low

 
UPDATE:
I’ve also found some information from Microsoft’s site to fix the problem.  They even include a Microsoft Fix It utility to fix the problem automatically: http://support.microsoft.com/kb/973479.

12/2/2014 UPDATE:
I recently had a client contact us about this very problem but the challenge was slightly different.  The web application (online credit card processing) was using framesets and IE was attempting to print an empty frameset.  Microsoft suggests turning on Compatibility Mode, however, I suggested:

  • Highlight what you’d like to print
  • Right click the selection
  • Click Print
  • Make sure to select “Selection” in the page range box
  • Click Print

RFID Standards

22 de Janeiro de 2016 – 10:02
  • 125 Khz (low-frequency) tags are write-once/read-many, and usually only contain a small (permanent) unique identification number.
  • 13.56 Mhz (high-frequency) tags are usually read/write, they can typically store about 1 to 2 kilbytes of data in addition to their preset (permanent) unique ID number.
  • 860-960 Mhz (ultra-high-frequency) tags are typically read/write and can have much larger information storage capacity (I think that 64 KB is the highest currently available for passive tags) in addition to their preset (permanent) unique ID number.

Most read/write tags can be locked to prevent further writing to specific data-blocks in the tag’s internal memory, while leaving other blocks unlocked. Different tag manufacturers make their tags differently, though.

Depending on your intended application, you might have to program your own microcontroller to interface with an embedded RFID read/write module using a manufacturer-specific protocol.

SQL SERVER – FIX : Error 15023: User already exists in current database.

9 de Abril de 2015 – 11:17

Error 15023: User already exists in current database.

1) This is the best Solution.

First of all run following T-SQL Query in Query Analyzer. This will return all the existing users in database in result pan.

USE YourDB
GO
EXEC sp_change_users_login 'Report'
GO

Run following T-SQL Query in Query Analyzer to associate login with the username. ‘Auto_Fix’ attribute will create the user in SQL Server instance if it does not exist. In following example ‘ColdFusion’ is UserName, ‘cf’ is Password. Auto-Fix links a user entry in the sysusers table in the current database to a login of the same name in sysxlogins.

USE YourDB
GO
EXEC sp_change_users_login 'Auto_Fix', 'ColdFusion', NULL, 'cf'
GO

Run following T-SQL Query in Query Analyzer to associate login with the username. ‘Update_One’ links the specified user in the current database to login. login must already exist. user and login must be specified. password must be NULL or not specified

USE YourDB
GO
EXEC sp_change_users_login 'update_one', 'ColdFusion', 'ColdFusion'
GO
