It looked very nice, and I decided to implement it on one of my website. This website attracts quite a lot of visitors everyday, and also generates most of the Adsense income.

Fast forward one week further ad one of my colleagues send me an email telling me there was something wrong with my website.

So I fired up Google Analytics and it quickly became apparent that there was a problem indeed.

Google Analytics Overview

Apparently the Google Friend Connect code don’t like Internet Explorer 6.0, and instead of displaying my page, an error was displayed.
After removing the code, the visits went up again.

So it shows that you really need to test new code on a wide range of operating systems and browsers for compatibility issues.

BPlayer is a perfect example of such an iPhone app developed with IUI.
It features all Belgian radio stations that can be streamed in the browser. The advantage of streaming a chosen radio station inside a browser is that you can do multi-tasking with your iPhone, at least as of OS 3.0

Using this method, you can listen to your favourite radio station and still use your iPhone to send text/sms messages, browse pictures, check your stocks, …

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\ProtocolDefaults

You define a new DWORD value for your protocol.

If you test your protocol and it doesn’t seem to work, check out if it is not overrulled by a policy.

With Microsoft’s Group Policy Editor, you can define a group of settings to be applied to all computers in an AD domain.
If this is the case, you need to overrule the security zone setting on a different location:

HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\protocolDefaults

Of course, you need to make this change with the Group Policy Editor, so it is persistent if you reboot or reconnect.

This is some new behaviour of Internet Explorer and was driven by the fact that users indicated the need for easy hiding and disabling of toolbar add-ons.

You can read more about this on the IE 8 Readiness Toolit webpages.

LoadLibrary("yourdll") failed: This application has failed to start because
the application configuration is incorrect.
Reinstalling the application may fix the problem.

Bummer.

Opening up the dll with Dependency Walker gives following error message:

Error: The Side-by-Side configuration information for "YOUR.DLL" contains errors.
This application has failed to start because the application configuration is incorrect.
Reinstalling the application may fix this problem (14001).

The problem lies in the fact that Visual Studio ships with ATL 8.0 dll, and this requires a manifest to be delivered together with the ATL80.dll.
A simple solution was to include both ATL80.dll and Microsoft.VC80.ATL.manifest into the installer, and copy it into the same installation directory as YOUR.DLL.
Both files can be found on following location on a standard Visual C++ installation:
C:\Program Files\Microsoft Visual Studio 8\VC\redist\x86\Microsoft.VC80.ATL

begin
 DBMS_RLS.ADD_POLICY (
   'MYSCHEMA',
   'MYTABLE',
   'MY_POLICY_NAME',
   'MYSCHEMA',
   'MY_POLICY_FUNCTION',
   'SELECT',
   SEC_RELEVANT_COLS     => 'COL1, COL2',
   sec_relevant_cols_opt => dbms_rls.ALL_ROWS
  );
end;

Normally you would query the dba_policies data dictionary view in order to see what policies are defined, but this data dictionary view does not include the relevant columns for the policy.
In order to see what columns are impacted by a certain policy, you need to query the dba_sec_relevant_cols data dictionary view.

SQL> SELECT object_owner, object_name, sec_rel_column 
      FROM DBA_SEC_RELEVANT_COLS;

OBJECT_OWNER             OBJECT_NAME              SEC_REL_COLUMN
------------------------ ------------------ ------------------------
MYSCHEMA                 MYTABLE            COL1
MYSCHEMA                 MYTABLE            COL2

SQLSTATE[HY000] [2002]
Can't connect to local MySQL server
through socket '/tmp/mysql.sock' (2)

The solution is to change the hostname in the mysql connect information screen into 127.0.0.1 instead of localhost.
If the port number mysql is running on is different than the default, mysql ignores it when you do not specify 127.0.0.1.

$ uname -i
i386

i386 is a 32-bit machine, while x86_64 or ia64 are 64-bit cpu’s

You can check /proc/cpuinfo for more information about the number and types of cpu on a system.

If you want to check the version of an executable file on Linux, you can do so with the readelf command

readelf -h oracle
