Accessing Stored Procedures Using ADO.NET

From here.

// create the connection
OracleConnection conn = new OracleConnection("Data Source=oracledb;
    User Id=UserID;Password=Password;");
// create the command for the stored procedure
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "SELECT_JOB_HISTORY.GetJobHistoryByEmployeeId";
cmd.CommandType = CommandType.StoredProcedure;
// add the parameters for the stored procedure including the REF CURSOR
// to retrieve the result set
cmd.Parameters.Add("p_employee_id", OracleType.Number).Value = 101;
cmd.Parameters.Add("cur_JobHistory", OracleType.Cursor).Direction =
    ParameterDirection.Output;
// createt the DataAdapter from the command and use it to fill the
// DataSet
OracleDataAdapter da = new OracleDataAdapter(cmd);
DataSet ds = new DataSet();
da.Fill(ds);
// output the results.
Console.WriteLine(ds.Tables[0].Rows.Count);

Add static libraries *.jar to Android.mk based build

in Android.mk

LOCAL_STATIC_JAVA_LIBRARIES := mylocaljar

LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := mylocaljar: mylocaljar.jar

mylocaljar.jar should be in root directory of the project. Look at the Calculator app's Android.mk in Android tree as an example

Blogpost code highlighting

Here I found how to highlight code in my blogposts on Blogspot. It's still not ideal because it doesn't support the original indentation but better nothing.

Nice piece of code from Android e-mail client

public static AsyncTask runAsync(final Runnable r) 
{  return new AsyncTask() {
       @Override 
       protected Void doInBackground(Void... params) {
            r.run();
            return null;
       }}.execute();
    }
    runAsync(new Runnable() {
      @Override
      public void run() {}}
    );

Market filters

Today's challenger was the defect where some Android devices did not see some apps on Android Market and some other did. Android is complicated in this area too. If your device is not good for a certain app Android Market hides the app rom the view. On one hand it's good. If your device cannot run an app why bother and display it? On the other what if I, a user, want this app so bad that I wanna buy a new phone just to make this app happy. How am I supposed to know what phone I need and what features or operating system version it should have?

Anyway the solution (not for newbies) lies here. This article explains a million complicated reasons why you don't see your app. I think Google should always display apps like that. But it should not let user to install them with explanations why.

Broadcast receiver problem

Today I saw a weird bug. I had a broadcast receiver in one app's AndroidManifest.xml

<receiver android:name=".MyReceiver">

<intent-filter>

<action android:name="com.my.intent.update" />

</intent-filter>

</receiver>

and another app sent broadcast with the intent the first app had to handle.

Intent intent = new Intent("com.my.intent.update");

sendBroadcast(intent);

The problem was it never did. I spent some time and asked my co-worker to look at it with me. While looking I found the problem (pair programming works after all). I had an activity in the same manifest file that had a receiver that handled the same intent!

<activity android:label="Test" android:name=".HomeActivity"

android:launchMode="singleTask" android:configChanges="orientation">

<intent-filter>

<action android:name="com.my.intent.update" />

</intent-filter>

</activity>

I don't know why it was there but it made receiver never handle the intent.

Curse of SSD

"The problem with an SSD is [that] data is written in blocks. A block may be 256KB: 256 * 1000 * 8 binary digits. To change even ONE of these digits, you must rewrite the ENTIRE block. That is to say, your OS sees 1 bit being written, but the SSD wear is equivalent to 256KB being written: a 2.048 MILLION fold difference." From here

Time machine issue solved

I had issues with Time Machine backups. After some time while backing up Time Machine gave me a finger: ". . . an error occurred while copying files to the backup volume" and a suggestion to repair disk. Nothing the error message suggested worked. I repaired disk, verified it and even formatted. Until I tried this tip.

I like this command

find . -type f -name "file_to_remove" -exec rm -f {} \;

finds a file by name or mask in current directory and recursively and deletes it :) From here.

Can one Android app have more than one icon in app launcher?

Why not! Just add this to your favorite AndroidManifest.xml:

<application>
<activity android:name="AActivity" android:icon="@drawable/a_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/a_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="BActivity" android:icon="@drawable/b_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/b_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="CActivity" android:icon="@drawable/c_icon" android:launchMode="singleTask"
android:screenOrientation="portrait"
android:label="@string/c_name"  android:theme="@android:style/Theme.Translucent.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity></application>

and that's it. You'll get s single app with three different app icons: a_icon, b_icon, c_icon.

How do you delete a downloaded timesheet in QuickBooks so it can be resubmitted?

You need to delete the incorrect time from your QuickBooks first, and then ask this employee to use the following utility to re-submit his/her timesheet for that week.

This utility changes the status for a week's worth of time activities. The employee time trackers must perform the steps to update their own activities.

1. Login to the Row View and navigate to the week of time activities you would like to update the status for.

2. Click the Switch to Calendar View link.

3. From the Calendar View, click the Switch to Row View link.

4. Change the following parameters to the end of the URL of the page to invoke the repair utility:

&cmd=repair&status= submitted

The full URL should look something like this:

https://timetracking.quickbooks.com/j/tts/tts_timesheetweek=1222714800000&ampcmd=repair&ampstatus=subm...

5. When done adjusting the URL, press the Enter key on the keyboard to load the next page.

6. If the statuses were successfully updated, you will see a success message on the Timesheet Repair Status page.

7. Click on the Undo Submit button, make the necessary changes to the timesheet, and then submit the timesheet again.
