OVERVIEW
This Application Note discusses how to create a dynamic dialog box and provides a sample dialog box definition table and sample macro code you can use to activate the dialog box. It also provides an example of one way you can retrieve information from a dynamic dialog box and enter that information in a database.

WHEN TO USE A DYNAMIC DIALOG BOX
When you want to reflect changes that you make within a dialog box without having to remove the dialog box from the screen, you can use a dynamic dialog box along with a control macro. An example of a dynamic dialog box in Microsoft Excel is the Workspace dialog box: when you choose Workspace from the Options menu, the dialog box appears; and when you select the Fixed Decimal check box, the Places check box is automatically selected and the dialog box remains on the screen.

CREATING A CUSTOM DYNAMIC DIALOG BOX
To create a dynamic dialog box, you define items in the dialog box so that they act as "triggers." To make your dynamic dialog box work, you also create macro code that recognizes these triggers and displays and redisplays your dialog box as these items are selected. When you select a dialog box item that is a trigger, your macro continues running and the dialog box remains on the screen.

When you create a dynamic dialog box, you use the same procedure that you use to create the dialog box definition table for a custom dialog box (for more information about creating custom dialog boxes, see pages 263-282 in the "User's Guide 2"). You make the dialog box dynamic by defining items in the dialog box to make them work as trigger items.

TO CREATE A TRIGGER ITEM
To create a trigger item, add 100 to the item type number in the dialog box definition table (this number is located in the first column of the dialog box definition table). For example, to make a list box item act as a trigger, change its item type number from 15 to 115.

NOTE: The Dialog Editor allows you to set items as triggers when you define your dialog box.

All dialog box items can be used as triggers except the following: fixed text (item 5), group boxes (item 14), icons (item 1), and directory text (item 20).

You can also control whether certain options are available or unavailable (dimmed). This feature is useful when you want a certain dialog box item to be unavailable until you choose a related item. To make a dialog box item unavailable, add 200 to the item number. For example, to make an option button (item number 12) unavailable, specify 212 in the item number column of the dialog box definition table.

SETTING UP YOUR COMMAND MACRO
When you create the command macro for a dynamic dialog box, you must set up the initial dialog box and then provide the structure to redisplay the macro when you select a trigger item.

TO SET UP THE INITIAL DIALOG BOX

 * 1) Determine how the dialog box will appear when it is first displayed. To modify the dialog box items, change the values in the Init/Result column of the dialog box definition table; for example, you can clear or set values in various editable items, enter default text in text edit boxes, and disable or clear items.
 * 2) Set your trigger items by changing the item numbers in the first column of the dialog box definition table.

REDISPLAYING THE DIALOG BOX
To test if a trigger item has been selected, you can use a WHILE-NEXT loop in your macro. In the WHILE-NEXT loop, the exit condition should reflect a choice you make in the dialog box. For example, the WHILE function could test for a specific value returned by the DIALOG.BOX function.

Dialog box items are numbered 0, 1, 2, and so on, starting with the first line in the dialog box definition table. The DIALOG.BOX function will return one of these numbers; your macro should use these numbers to determine which item in the dialog box was selected. Note that the Cancel button (item type 4) always causes the DIALOG.BOX function to return a value of FALSE. You can then specify any changes you want your macro code to make before the macro redisplays the dialog box.

RULES TO FOLLOW WHEN MAKING CHANGES TO THE DIALOG BOX DEFINITION TABLE
When you make changes to the dialog box definition table, keep the following in mind:


 * To enable or disable items in the definition table, use the SET.VALUE function instead of directly adding or subtracting 200 from the item number. (When you use the SET.VALUE function, you avoid problems in cases where you select the same trigger item twice and 200 is added or subtracted twice from the item number.)
 * Updating the dialog box will be less noticeable if you call the same dialog box definition table or call one that has dimensions similar to the original box.
 * Don't use ECHO(FALSE) with a dynamic dialog box. This function may cause problems when your screen is refreshed.

EXAMPLE OF A DYNAMIC DIALOG BOX
Use the following procedures to create a dynamic dialog box and a control macro. The control macro includes sample macro code that uses the FORMULA function to retrieve information that you enter in the dialog box. The macro takes this information and enters it in a database called DBASE.XLS.

TO CREATE THE DIALOG BOX
  In cells D1:K29 of a new macro sheet, enter the following dialog box definition table:

      D      E      F    G      H      I          J                K - 1 |Item # | Item | x |  y | width |height |    Text        |Init/Result |      | Type |    |    |       |       |                | - 2 |  0                        325    335                           4  3 |  1        5     65    9                   INVOICE - Shipping |                                          Information 4 | 2        5     15   20  5 |  3        5     14   42                   Invoice #: 6 | 4        8     97   38   109  7 |  5        5     14   65                   Customer 8 | 6        5     14   81                   Name: 9 | 7        6     97   70   206 10 |  8        5     12   95 11 |  9       14      9  111   147     55      Shipping Method 12 | 10      11                                                      1 13 | 11      112                               U.S. Mail 14 | 12     112                               Next Day Air 15 | 13     205    167  111                   Overnight Carrier: 16 | 14     206    165  141   141 17 | 15      113     14  174                   Address Different    FALSE |                                          from Previous? 18 | 16     205     65  196                   New Shipping Address 19 | 17     205     11  209 20 | 18      205      9  229                   Street 21 | 19     206     61  227   248 22 | 20      205     22  258                   City 23 | 21     206     61  253    93 24 | 22      205    168  258                   State 25 | 23     206    216  253    93 26 | 24      205    146  280                   Zip Code 27 | 25     208    216  279    93 28 | 26        1      5  307   151             Enter Information 29 | 27       2    165  307   151             Cancel Request -

Note that column D is not part of the dialog box definition table. This column is provided in this example to help identify the item numbers. For example, item numbers 11, 12, and 15 are triggers in  this dialog box. Items 13, 14, and 16 through 25 are unavailable (or dimmed).  Select cells E2:K29. From the Formula menu, and choose Define Name. In the Name box, type BOX. (Naming the table will make it easier to refer to the dialog box definition table when you write your macro.) To view your dialog box:

 Type the following commands in cells C1 and C2:

=DIALOG.BOX(box)

=RETURN Select cell C1 and choose Run from the Macro menu.</li> Choose OK.</li></ol> </li></ol>

Your dialog box should resemble the following example (depending on your screen resolution, the position of the items in the dialog box will vary).

[Graphic deleted]

NOTE: Your dialog box should resemble the example above. If it does not, make sure that your dialog box definition table matches the one previously shown.

To remove the dialog box from your screen, choose the Cancel Request button.

TO CREATE A COMMAND MACRO
<ol>  In column A, type the following command macro:

<pre class="FIXEDTEXT">     |  A -- 1 | dialog_box_macro 2 | =SET.VALUE(K2:K29,"") 3 | =SET.VALUE(K2,4) 4 | =SET.VALUE(K12,1) 5 | =SET.VALUE(K17,FALSE) 6 | finished=FALSE 7 | =WHILE(finished=FALSE) 8 | =IF(K12=1,SET.VALUE(E15:E16,{205;206})) 9 | =IF(K17=FALSE,SET.VALUE(E18:E27,{205;205;205;206;205;206; | 205;206;205;208}))   10 |  dialog_box=DIALOG.BOX(box) 11 | =IF(dialog_box=FALSE,RETURN) 12 | =IF(dialog_box=12) 13 | =SET.VALUE(E15:E16,{5;6}) 14 | =SET.VALUE(K2,14) 15 | =ELSE.IF(dialog_box=15) 16 | =SET.VALUE(E18:E27,{5;5;5;6;5;6;5;6;5;8}) 17 | =SET.VALUE(K2,19) 18 | =ELSE.IF(dialog_box=26) 19 | finished=TRUE 20 | =END.IF 21 | =NEXT 22 | =RETURN </li> To run this macro, select cell A1 and choose Run from the Macro menu.</li></ol>

When you choose a certain shipping method, you are prompted for more information. Also, if you specify a change of address, you will be prompted for the new address specifics.

If you select the "U.S. Mail" or "Next Day Air" button or the "Address Different from Previous?" check box, the macro will continue to execute but the dialog box will remain on the screen. The macro then uses the DIALOG.BOX function to determine which trigger was selected, performs a task based on that selection, and then redisplays the dialog box.

TO RETRIEVE INFORMATION FROM THE DIALOG BOX AND PLACE IT IN A DATABASE
To retrieve information entered in the dialog box and place it in a database, you need to add more commands to your command macro.

To add macro code that will take information that you enter in the Invoice and Customer Name boxes, enter the information in a database, and redefine the database to include the new information, do the following:

<ol> In cell A22, delete the RETURN function.</li>  Starting in cell A22, add the following code to your macro:

<pre class="FIXEDTEXT">     | A - 22 | =ACTIVATE("dbase.xls") 23 | first_cell=TEXTREF(GET.CELL(1,DBASE.XLS!Datab | ase),TRUE) 24 | =FORMULA(DDBOX.XLM!K6,OFFSET(first_cell,ROWS(     | !Database),0)) 25 | =FORMULA(DDBOX.XLM!K9,OFFSET(first_cell,ROWS(     | !Database),1)) 26 | =SELECT(OFFSET(first_cell,0,0,ROWS(!Database) | +1,2))  27 | =SET.DATABASE 28 | =SELECT(first_cell) 29 | =RETURN </li> From the File menu, choose Save. Name your document DDBOX.XLM.</li> From the File menu, choose New and select Worksheet. Choose OK.</li> In cell A1 in the new worksheet, type INVOICE NUMBER and in cell B1, type CUSTOMER.</li> Select cells A1:B1.</li> From the Data menu, choose Set Database and save the worksheet with the database as DBASE.XLS.</li> From the Window menu, choose DDBOX.XLM.</li> Select cell A1 and choose Run from the Macro menu.</li></ol>

When you type a number in the Invoice number box, type a name in the Customer Name box, and choose Enter Information, the information is entered in the database (DBASE.XLS) and your database range is automatically extended to include the new information.

NOTE: To gain a better understanding of how the command macro works with the dynamic dialog box, you can run the macro by choosing the Run command from the Macro menu and choosing the Step button.
