  Hi BANGER67,

  CLR20r3 is associated with the .net framework. I suggest you try the following steps:

  Step 1: Clean boot the computer, and check to see if the problem persists

  Follow step 1 in the link below,

  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

  http://support.Microsoft.com/kb/929135

  If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

  Continue with the remaining steps to pin-point on the third party service.

  After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

  Important: n ' forget not the computer to start normal follow step 7 in the link.

  Step 2: Remove and reinstall the .NET Framework (see method 3 in the link below)

  Type of event: clr20r3

• I received calls from someone in India who said that they are Windows services centre telling me that they have received the error message saying that my computer is corrupted

  Original title: my computer is corrupt and needs fixing!

  I received calls from a person in India who said that they are Windows services centre telling me that they have received the error message saying that my computer is damaged, and they want to help me.  But I have not received any error message on my screen.  When I asked them how they got my number they said it's from the database of Windows. The number they gave me is 02921252715 and when I called the number of the person on the other end told me that they are a company called Windows e-solution, independent company and is not attached to Microsoft Windows.  What should I do?  Are these authentic calls and approved by Microsoft Windows?

• Receive the error message "the instruction at"0 x 00424590"referenced memory at"0 x 00000004", the memory could not be"written"." Error is received before the Windows logon prompt

  Receive the error referenced memory before you receive the logon prompt Windows session during the boot process.  Have replaced the RAM on the computer.  Windows Xp SP3.

  If anyone can identify the update that they think that may be the cause of the problem, you can navigate to the uninstall folder and determine what files have been updated.  If they can not start (except in the Recovery Console), you can also sort updates the date by using the dir command in the folder c:\windows (all $NtUninstall records).

  Problem is who writes all updates with Patch Tuesday comes around (say... it's today!-be prepared for positions "broken Windows my computer updates" start coming!).

  For example:

  When you install an update, first installation makes a copy of the files he wants to replace in the $ $NtUninstallKBnnnnnn... folder.

  That's why you can uninstall the update later.  Running uninstall the update will sometimes remove the updated files, then copy the original return files.  Sometimes uninstalling copy just the original preupdate on top of the most recent files.  It can also remove some registry keys, so Windows Update do not think you have more (look at the spuninst.inf file).

  Look at this update of security for example (KB950762) that updates c:\windows\system32\drivers\rmcast.sys:

  If you have installed, it will create this folder:

  c:\windows\$NtUninstallKB950762$

  You will have the front update file c:\windows\system32\dllcache\rmcast.sys in this folder since the installation of the update makes a copy of the original file for you.

  Then look at the file spuninst.txt spuninst folder and you will see what will happen if you need to uninstall the update:

  DEL "c:\windows\$hf_mig$\kb950762\sp3qfe\rmcast.sys".
  COPY 'C:\WINDOWS\$NtUninstallKB950762$\rmcast.sys' 'c:\windows\system32\dllcache\rmcast.sys '.
  COPY 'C:\WINDOWS\$NtUninstallKB950762$\rmcast.sys' 'c:\windows\system32\drivers\rmcast.sys '.
  COPY 'C:\WINDOWS\$NtUninstallKB950762$\spuninst\spuninst.txt' 'C:\WINDOWS\$NtUninstallKB950762$\spuninst\spuninst.tag '.

  In this case, uninstalling just copy the original file on top of the files that have been applied in the update, the spunint.inf updates registry tips and that's all.

  Notice that it also replaces the file in the dllcache folder too - c:\windows\system32\drivers\rmcast.sys is one of the 3498 drop that PAM cares everything (it's number 2500 in the list).  In dllcache files are backup files.

  If you were to access your drivers folder and rename c:\windows\system32\drivers\rmcast.sys to rmcast.lem, almost before you can Flash the 'missing' file will be replaced with the copy in the dllcache folder and you will see this in the event log:

  Event type: Information
  Event source: Windows File Protection
  Event category: no
  Event ID: 64002
  Description:
  File replacement was attempted on the protected system file c:\windows\system32\drivers\rmcast.sys. This file was restored to the original version to maintain system stability. The file version of the system file is 5.1.2600.5598.

  It is WFP in action and this means that WFP is working!

  java.sql.SQLException: ORA-00904: "SAND": invalid identifier

  Looks like the sql that you present is not valid.
  Print a copy of the sql that you try to run and you will probably get:

  SELECT * FROM OURUSERS WHERE usr = Sandy and password = secret
  

  Is not valid sql. Missing quotation marks around the values that you control.
  This is the sql query was corrected:

  SELECT * FROM OURUSERS WHERE usr = 'Sandy' and password = 'secret'
  

  If a solution would be:

  String sql = "SELECT * FROM OURUSERS WHERE usr = '" + user + "' and password = '" + pwd + "' ";
  

  However, this is not optimal. It exposes your code to the sql injection attack.
  The best way is to use a prepared statement:

  String sql = "SELECT * FROM OURUSERS WHERE usr = ? and password =?";
  st = con.prepareStatement(sql);
  st.setString(1, user);
  st.setString(2, password);
  
  rs = st.executeQuery();
  

  see you soon,

• I received the error message: 0x0000ffff after running the system restore

  Original title: 0x0000ffff

  has run the system restore and got this error code. How should I do?

  Hello

  could a. you give the error message as well?
  b. are you try to create a system restore point or restore the computer to a previous state?

  c. Why do you try to restore the computer to a previous state?

  We can try the following methods and check.

  Method 1.
  Disable the security software and then try to run the system restore and verify.

  Method 2.

  Let us run restore the system from the command prompt and check. Follow the steps described in the article below to get there.

  Start the restore of the system from a command prompt
  http://Windows.Microsoft.com/en-us/Windows7/start-System-Restore-from-a-command-prompt

  Method 3.

  I also advise to use the boot minimum troubleshooting to find the conflicting program.

  You can also consult the methods listed in the section below to learn more.
