SYMPTOMS

When attempting to use the TAB key to navigate through controls on a Sheridan Tab Control, the cursor appears to "stick" in one control. This occurs when the SetFocus method is used in the Tab Control's Click or GotFocus event to shift focus to one of the constituent controls. Download the most recent version of the Tab Control from the address listed below.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Visual Basic version 4.0. Microsoft is researching this problem and will post new information here as it becomes available.

This problem has been corrected in version 4.01 (or greater) of the SSTab control. Please note that the following file is for Visual Basic 4.0 32-bit only. TABCTL32.ZIP (version 4.02)is available at:

MORE INFORMATION

This occurs on Win95, NT 4.0, and Windows 2000 but does not occur in NT 3.51 or Visual Basic 16-bit.

Steps to Reproduce Problem

  1. Create a new Project.
  2. Add an SSTAB control to the default form
  3. Adjust the following properties on SSTAB1:
       TABSTOP = False
    						
  4. Add two Textboxes to each page of the Tab control (for a total of six).
  5. In the SSTAB's CLICK or GOTFOCUS method, add the following code:
          On Error Resume Next
          IF SSTAB1.TAB = 0 THEN
             Text1.setfocus
          ELSEIF SSTAB1.TAB = 1 THEN
             Text3.SetFocus
          ELSE
             Text5.SetFocus
          END IF
    						
  6. Save the project and run the form.
  7. When the form displays, the focus is on Tab0. Press the TAB key several times and notice that tabbing occurs normally.
  8. Now click on Tab1 (the 2nd page), and note that the I-Beam is in the first Textbox (Text3). Press the TAB key repeatedly and note that the focus does not leave the Textbox.
