Slide 9 Enhancing Maintain Applications with HTML Loading the Stack  A stack is an array containing database or computed fields  Columns are fields and rows are data  Reads Master File to know field names, formats, lengths and position  Load up a stack with the NEXT command  We are loading 10 records into a stack named STK  Click Save

Copyright 2007, Information Builders. Slide 10 Enhancing Maintain Applications with HTML Creating a Form  Expand the LAB1 folder  Expand the Forms folder  Double-click on Form1 to display the form  Maximize the form

Copyright 2007, Information Builders. Slide 11 Enhancing Maintain Applications with HTML Adding an HTML Table  Select the HTML Table object from the Control Palette  Click on the upper left corner of the form, drag the cursor to the right side of the form to create a rectangle.  Select Stk and move over: Moviecode, Title and Category  Click OK

Copyright 2007, Information Builders. Slide 12 Enhancing Maintain Applications with HTML Running the Application  Save and Run  Right-click on LAB1 and select Run Procedure  Once Deployment is successful, click Close

Copyright 2007, Information Builders. Slide 13 Enhancing Maintain Applications with HTML Running the Application  Click X to return to the MDE  If code is not displayed, double-click on LAB1

Copyright 2007, Information Builders. Slide 14 Enhancing Maintain Applications with HTML Adding a Checkbox  Add a Checkbox to an HTMLTable to allow the user to select a row  Use HTML Tags  Input Type: CheckBox  Name: Must be unique for each row  Value: 1 or blank. You can change retrieval value  Use Form.GetHTMLField to retrieve the values from the HTMLTable.  You cannot resort this stack after you create the Checkbox

Copyright 2007, Information Builders. Slide 15 Enhancing Maintain Applications with HTML Enhancing the Code  Create a cbox field in STK for every row in the stack – Stk.Foccount  Give each check box a unique name – Concatenate counter to ‘check’  If checked, the returned value is 1. That can be changed  Create GetData case to retrieve selections  Create Sel field to retrieve values from HTMLTable – Uses GetHTMLField  Save!

Copyright 2007, Information Builders. Slide 16 Enhancing Maintain Applications with HTML Editing the HTML Table  Double-click on Form1 to display the form  Double-click on the HTMLTable to display the columns  Scroll down. Notice that cbox and Sel are on the column list

Copyright 2007, Information Builders. Slide 17 Enhancing Maintain Applications with HTML Editing the HTML Table  Add Cbox and Sel to the Table columns  Use the arrows to make Cbox the first field  Double-click on Cbox to edit the column

Copyright 2007, Information Builders. Slide 18 Enhancing Maintain Applications with HTML Editing the HTML Table  Change the Width of Cbox to 6.  Change the Content type from: 0 – Text To1 – HTML  Click OK to exit this screen  Click OK to return to the form

Copyright 2007, Information Builders. Slide 19 Enhancing Maintain Applications with HTML Adding a Button  Select the button object from the tools palette.  Draw a rectangle under the HTMLTable  Change the text to Process  Click on the Events Tab for the button  Select the Click Event and the Events screen opens

Copyright 2007, Information Builders. Slide 20 Enhancing Maintain Applications with HTML Adding a Button  Button1 & Click are selected and Maintain function is clicked  Expand the Functions folder  Drag the GetData case from Functions into the Event  Save and Run - Right-mouse click on LAB1 and select Run Procedure

Copyright 2007, Information Builders. Slide 21 Enhancing Maintain Applications with HTML Running the Application  To pre-check a value, use the keyword CHECKED Compute Stk(I).cbox/a100 = " ";  NOTE: Do not resort the stack when using this technique!

Copyright 2007, Information Builders. Slide 22 Enhancing Maintain Applications with HTML Adding a List Box  Add a List Box to an HTMLTable to allow the user to select a value from a drop down list  Use HTML Tags  Select  Name: Must be unique for each row  Value: Retrieval and display  Value can be static or dynamic  Retrieve database values and assign them  Use Form.GetHTMLField to retrieve the values from the HTMLTable.  You cannot resort this stack after you create the List Box

Copyright 2007, Information Builders. Slide 23 Enhancing Maintain Applications with HTML Adding a List Box  Double click on LAB1  Create a lbox field in Stk  There are two values for each entry:  Retrieval and Display  This code leaves row 1 blank  Add a line in GetData  NewRate contains the selected value.  SAVE  Click on Form1 to display the form.  Double-click on the HTMLTable

Copyright 2007, Information Builders. Slide 24 Enhancing Maintain Applications with HTML Adding a List Box  Add fields Lbox, Rating and Newrate to the columns  Double-click on Title and change its width to 20. Click OK  Double-click on Lbox to change its format

Copyright 2007, Information Builders. Slide 25 Enhancing Maintain Applications with HTML Adding a List Box  Change the width to 10  Change the content type to 1 – HTML  Click OK to save  Click OK to return to the Form  Save and Run  NOTE: Do not resort the stack when using this technique!

Copyright 2007, Information Builders. Slide 26 Enhancing Maintain Applications with HTML Running the Application  When you process, all list boxes reset  Retrieve all values before screen resets  This example shows static values. You can substitute values for values in the database and only show valid items per line. Like Cars by Country or Employees by Department.
