The cmdPrevious button s Click event looks very similar: Private Sub cmdPrevious_Click() Dim iPrevious As Integer StoreData iPrevious = m_oWizard.PreviousPage Me.MultiPage1.Value = m_colSteps(CStr(iPrevious)).Order - 1 Me.MultiPage1.Pages((m_colSteps(CStr(iPrevious)).Page) - 1).Caption = m_colSteps(CStr(iPrevious)).Caption ShowNextPage "down" End Sub The only difference is that we are passing the keyword down to the ShowNextPage method so that we move the user in the proper direction. Let s add one last event handler to assist us with our navigation. Whenever we change pages on a MultiPage control, the control s Change event fires. We ll use that event to grab the value of the current page and store it in our m_oWizard object s CurrentPage property. Add the following code to the MultiPage1 control s Change event: Private Sub MultiPage1_Change() m_oWizard.CurrentPage = MultiPage1.Value + 1 End Sub Now that we have our navigation working, let s give it a try: 1. With the UserForm open in Design view, click the Run button on the Standard toolbar or press the F5 key. 2. Once the form is open, click the Next Button to move to the second step in our wizard, as defined on our configuration worksheet. This should be the Address screen. Notice that both navigation buttons are now enabled, as shown in Figure 4-32. 3. Click the Previous button to navigate back to the Personal screen, and the Previous button will no longer be active. 4. Click the Next button until you are at the last screen as defined on our configuration worksheet. This should be the Network Access screen. The Next button will no longer be enabled, as shown in Figure 4-33. 5. Stop the form by clicking the X button.

Figure 9-7. The Pending comments listing block after it has been enabled. It shows two pending comments. Now that the Pending comments block is finished, let s define another block within this approval_block() function one that lists all unpublished nodes and provides a link to their edit page: function approval_block($op = 'list', $delta = 0, $edit = array()) { switch ($op) { case 'list': $blocks[0]['info'] = t('Pending comments'); $blocks[1]['info'] = t('Unpublished nodes'); return $blocks; } } Notice how the blocks are each assigned a key ($blocks[0], $blocks[1], . . . $blocks[n]). The block module will subsequently use these keys as the $delta parameter. Here, we ve defined the $delta IDs to be 0 for the Pending comments block and 1 for the Unpublished nodes block. These could just as easily have been 'pending' and 'unpublished'. It s at the programmer s discretion to decide which keys to use, and the keys need not be numeric. Here s the complete function; our new block is shown in Figure 9-8: function approval_block($op = 'list', $delta = 0, $edit = array()) { switch ($op) { case 'list': $blocks[0]['info'] = t('Pending comments'); $blocks[1]['info'] = t('Unpublished nodes'); return $blocks; case 'configure': // Only in block 0 (the Pending comments block) can one // set the number of comments to display. if ($delta == 0) { $form['approval_block_num_posts'] = array( '#type' => 'textfield', '#title' => t('Number of pending comments to display'), '#default_value' => variable_get('approval_block_num_posts', 5), ); }

CLASS { margin-top:-VALUE; } Location Explanation This pattern applies to block elements This pattern is the opposite of the Block Spacer design pattern and has the exact opposite structural meaning By drawing two blocks closer together, the markup indicates they are more closely related The class name you assign to the block space remover element should reflect this purpose Furthermore, the structural relationship created by a block space remover or block spacer element does not belong to either block It belongs in between the blocks because it links or separates them It is best to use structural markup to create structural meaning because it is easiest to maintain you can see it and manipulate it directly in the HTML Advantages Unlike the block spacer, the block space remover does not uncollapse margins This makes using the block spacer remover simpler and more predictable.

This design pattern requires an extra element to be inserted into the markup for each space you want to remove If you remove too much space, you can cause blocks to overlap In the example, each paragraph has been assigned to top and bottom margins of 32 pixels The two paragraphs in the second section are preceded and followed by block space removers, which remove the space before, between, and after these paragraphs Visual Structure, Collapsed Margins, Block Spacer; Margin ( 6) wwwcssdesignpatternscom/block-space-remover.

Figure 4-33. The Next button is disabled on the last screen in the wizard. Saving the Employee Record We ve done a lot of work so far, and we ve got some pretty neat functionality provided to our UserForm from our custom objects. The only thing missing is saving the data to the EmpData worksheet.
