TEMPO.CO, Jakarta - Menulis di blog tak sama dengan menulis di microblog seperti Twitter. Perbedaan mencolok yang terlihat adalah jumlah karakter yang tersedia. Selain itu, ide dan argumen yang ditampilkan di Twitter tak seutuh ketika menulis di blog.

Sayangnya, justru orang kini lebih senang menulis di microblog. Sebab, banyak pemilik blog yang semula rajin mengaktualisasi diri lewat tulisan di blog kini beralih ke jejaring sosial yang hanya butuh tulisan pendek.

   To add a list box in Excel 2003 and in earlier versions of Excel, click the List Box button on the Forms toolbar. If the Forms toolbar is not visible, point to Toolbars on the View menu, and then click Forms.
2. Click the worksheet location where you want the upper-left corner of the list box to appear, and then drag the list box to where you want the lower-right corner of the list box to be. In this example, create a list box that covers cells B2:E10.

4. In the Format Object window, type the following information, and then click OK.
   1. To specify the range for the list, type H1:H20 in the Input range box.
   2. To put a number value in cell G1 (depending on which item is selected in the list), type G1 in the Cell link box.
      Note The INDEX() formula uses the value in G1 to return the correct list item.
   3. Under Selection type, make sure that the Single option is selected.
      Note The Multi and Extend options are only useful when you are using a Microsoft Visual Basic for Applications procedure to return the values of the list. Note also that the 3-D shading check box adds a three-dimensional look to the list box.

5. The list box should display the list of items. To use the list box, click any cell so that the list box is not selected. If you click an item in the list, cell G1 is updated to a number that indicates the position of the item that is selected in the list. The INDEX formula in cell A1 uses this number to display the item's name.

Combo box example

1. To add a combo box in Excel 2010 and Excel 2007, click the Developer tab, click Insert, and then click Combo Box under Form Controls.
   
   
   

   

   
   Gambar.08
   

   
   
   To add a combo box in Excel 2003 and in earlier versions of Excel, click the Combo Box button on the Forms toolbar.
2. Click the worksheet location where you want the upper-left corner of the combo box to appear, and then drag the combo box to where you want the lower-right corner of the list box to be. In this example, create a combo box that covers cells B2:E2.
   
   
   
3. Right-click the combo box, and then click Format Control.
   
   
   
4. Type the following information, and then click OK:
   1. To specify the range for the list, type H1:H20 in the Input range box.
   2. To put a number value in cell G1 (depending on which item is selected in the list), type G1 in the Cell link box.
      
      Note The INDEX formula uses the value in G1 to return the correct list item.
   3. In the Drop down lines box, type 10. This entry determines how many items will be displayed before you have to use a scroll bar to view the other items.
      
      Note The 3-D shading check box is optional. It adds a three-dimensional look to the drop-down or combo box.
      
      
      
5. The drop-down box or combo box should display the list of items. To use the drop-down box or combo box, click any cell so that the object is not selected. When you click an item in the drop-down box or combo box, cell G1 is updated to a number that indicates the position in the list of the item selected. The INDEX formula in cell A1 uses this number to display the item's name.

Spin button example

1. To add a spin button in Excel 2010 and 2007, click the Developer tab, click Insert, and then click Spin Button under Form Controls.
   
   
   
   
   
   To add a spinner in Excel 2003 and in earlier versions of Excel, click the Spinner button on the Forms toolbar.
2. Click the worksheet location where you want the upper-left corner of the spin button to appear, and then drag the spin button to where you want the lower-right corner of the spin button to be. In this example, create a spin button that covers cells B2: B3.
3. Right-click the spin button, and then click Format Control.
   
   
   
4. Type the following information, and then click OK:
   1. In the Current value box, type 1.
      
      This value initializes the spin button so that the INDEX formula will point to the first item in the list.
   2. In the Minimum value box, type 1.
      
      This value restricts the top of the spin button to the first item in the list.
   3. In the Maximum value box, type 20.
      
      This number specifies the maximum number of entries in the list.
   4. In the Incremental change box, type 1.
      
      This value controls how much the spin button control increments the current value.
   5. To put a number value in cell G1 (depending on which item is selected in the list), type G1 in the Cell link box.
      
      
      
5. Click any cell so that the spin button is not selected. When you click the up control or down control on the spin button, cell G1 is updated to a number that indicates the current value of the spin button plus or minus the incremental change of the spin button. This number then updates the INDEX formula in cell A1 to show the next or previous item.
   
   The spin button value will not change if the current value is 1 and you click the down control, or if the current value is 20 and you click the up control.

Scroll bar example

1. To add a scroll bar in Excel 2010 and Excel 2007, click the Developer tab, click Insert, and then click Scroll Bar under Form Controls.
   
   
   
   
   
   To add a scroll bar in Excel 2003 and in earlier versions of Excel, click the Scroll Bar button on the Forms toolbar.
2. Click the worksheet location where you want the upper-left corner of the scroll bar to appear, and then drag the scroll bar to where you want the lower-right corner of the scroll bar to be. In this example, create a scroll bar that covers cells B2:B6 in height and is about one-fourth of the width of the column.
   
   
   
3. Right-click the scroll bar, and then click Format Control.
   
   
   
4. Type the following information, and then click OK:
   1. In the Current value box, type 1.
      
      This value initializes the scroll bar so that the INDEX formula will point to the first item in the list.
   2. In the Minimum value box, type 1.
      
      This value restricts the top of the scroll bar to the first item in the list.
   3. In the Maximum value box, type 20. This number specifies the maximum number of entries in the list.
   4. In the Incremental change box, type 1.
      
      This value controls how many numbers the scroll bar control increments the current value.
   5. In the Page change box, type 5. This value controls how much the current value will be incremented if you click inside the scroll bar on either side of the scroll box).
   6. To put a number value in cell G1 (depending on which item is selected in the list), type G1 in the Cell link box.
      
      
      
      
      
      Note The 3-D shading check box is optional. It adds a three-dimensional look to the scroll bar.
5. Click any cell so that the scroll bar is not selected. When you click the up or down control on the scroll bar, cell G1 is updated to a number that indicates the current value of the scroll bar plus or minus the incremental change of the scroll bar. This number is used in the INDEX formula in cell A1 to show the item next to or before the current item. You can also drag the scroll box to change the value or click in the scroll bar on either side of the scroll box to increment it by 5 (the Page change value). The scroll bar will not change if the current value is 1 and you click the down control, or if the current value is 20 and you click the up control.

Pengertian dan Fungsi BIOS

Gambar 42. BIOS

BIOS merupakan singkatan dari Basic Input Output System. BIOS merupakan sebuah program atau software antarmuka tingkat rendah yang berfungsi mengendalikan atau mengontrol perangkat keras yang terpasang pada komputer. BIOS disimpan atau ditanamkan di ROM ( Read Only Memory ).

Setiap Motherboard memiliki yang namanya BIOS, dan bila BIOS ini rusak maka kemungkinan besar motherboard tidak dapat digunakan kembali ( kecuali BIOS di install ulang atau di upgrade ). Karena BIOS ditanamkan di ROM, maka kemungkinan kita hanya bisa merubah pengaturan yang telah ada, misalkan kita merubah besarnya memory yang digunakan untuk VGA yang berjenis onboard, atau mengubah waktu dan tanggal, serta mengubah settingan dasar lainnya.
