20.3 Input Selection
The input options are:
0. Directory,
1. File,
2. Sub-Directory,
3. File Segment,
4. Access,
5. Access Segment,
6. *.avi file, and
7. Live Video.
The selection is implemented by the “Mode” button in Figure 19.2:
-
In Figure 19.1, select an input option.
-
In Figure 19.2, keep clicking the Mode button and the setting will switch from one to the next.
Double click the “Mode” button and enter:
private void button3_Click(object sender, System.EventArgs e)
{
gui.Button_Mode ();
}
Here, mainMenuToAPI is an object, which will implement all functions. As we discussed earlier, the main form simply links menu items to functions in the mainMenuToAPI object. The implementation is:
public void Button_Mode ()
{
iMode = (iMode + 1 )% strMode.Length ;
Button_Mode_consistent ();
}
where the third line is:
public void Button_Mode_consistent ()
{
if (iMode == 0 )
f.button3.Text = strMode[0];
else if (iMode == 1 )
f.button3.Text = strMode[1];
else if (iMode == 2 )
f.button3.Text = strMode[2];
else if (iMode == 3 )
f.button3.Text = strMode[3];
else if (iMode == 4 )
f.button3.Text = strMode[4];
else if (iMode == 5 )
f.button3.Text = strMode[5];
else if (iMode == 6 )
f.button3.Text = strMode[6];
else if (iMode == 7 )
f.button3.Text = strMode[7];
else
{
iMode = 0;
f.button3.Text = strMode[0];
}
f.richTextBox1.AppendText ( "Input source: " + f.button3.Text + "\n");
}
The access options are:
iMode = 4 (Access);
iMode = 5 (Access Segment).
The “Source” button specifies the input source based on the variable, iMode. Double click the “Source” button and enter:
private void button2_Click(object sender, System.EventArgs e)
{
gui.Button_SearachSource ( gui.iMode );
}
The implementation is:
public void Button_SearachSource (int iMode)
{
canLiveStart = false;
if ( iMode == 0 )
searachSource0 ();
else if ( iMode == 1 )
searachSource1 ();
else if ( iMode == 2 )
searachSource2 ();
else if ( iMode == 3 )
searachSource3 ();
else if ( iMode == 4 )
searachSource4 ();
else if ( iMode == 5 )
searachSource5 ();
else if ( iMode == 6 )
searachSource6 ();
else if ( iMode == 7 )
searachSource7 ();
else
searachSource0 ();
}
Therefore, the database implementation is given in the following functions:
searachSource4 ();
searachSource5 ().
