The information in this article applies to:

- Microsoft Visual FoxPro for Windows, versions 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When trying to use WhatsThisHelp to display the help for an object within a
grid, the help topic for that object is not displayed. Instead, the help topic
for the grid is displayed. If there is not a help topic assigned to the
WhatsThisHelpID for the grid, one of these two messages may appear:

  No help topic is associated with this item.

or

  Cannot find the requested help topic. This link may be incorrectly authored.
  Use the search or the index to find the topic.

RESOLUTION
==========

The following code displays the help topic for the text box control when one of
the first three columns of the grid is clicked on using WhatsThisHelp. Otherwise
it sets the WhatsThisHelpID to show the help for the grid. Add more CASE
statements to continue showing help for the rest of the columns in the grid.

       NODEFAULT
       DO CASE
          CASE MCOL(THISFORM.NAME,3) > 18 + THIS.LEFT AND ;
                MCOL(THISFORM.NAME,3) <= 18 + THIS.LEFT +  ;
                THIS.column1.WIDTH
              nWhatsThisHelpID  = 1342177844 && help topic number of textbox.
          CASE MCOL(THISFORM.NAME,3) > 18 +THIS.LEFT +THIS.column1.WIDTH ;
                AND MCOL(THISFORM.NAME,3) <= 18 +THIS.LEFT + ;
                THIS.column1.WIDTH + THIS.column2.WIDTH
               nWhatsThisHelpID = 1342177844 
          CASE MCOL(THISFORM.NAME,3) > 18 +THIS.LEFT +THIS.column1.WIDTH ;
                + THIS.column2.WIDTH AND MCOL(THISFORM.NAME,3) <= 18 ;
                + THIS.LEFT + THIS.column1.WIDTH + THIS.column2.WIDTH + ;
                 THIS.column3.WIDTH
               nWhatsThisHelpID = 1342177844  
          OTHERWISE
               nWhatsThisHelpID = 1342177839 && help topic number of grid.
       ENDCASE
       DODEFAULT(nWhatsThisHelpID)

Steps to Reproduce Behavior
---------------------------

1. Create a form, add a table to the Data Environment, and click on the title of
  the table and drag it to an area of the form to create a grid.

2. Set the following properties of the form:
  MaxButton = .F.
  MinButton = .F.
  WhatsThisButton = .T.
  WhatsThisHelp = .T.

3. Set the WhatsThisHelpID of the grid to the number 1342177839.

4. Set the WhatsThisHelpID of the grid's first column's text box to 1342177844.

5. Run the form and click on the WhatsThisHelp question mark in the upper right
  corner of the form and then click on the text box in column one of the grid.
  Notice that the Visual FoxPro help comes up showing the grid help topic.

6. Close the form, modify it, and add the code in the Resolution section of this
  article to the grid's ShowWhatsThis method.

7. Run the form and click on the WhatsThishelp question mark and then click on
  any one of the first three columns in the grid. Note that the text box help
  appears. Clicking anywhere else on the grid brings up the help for the grid
  control.
