Change Navigation pane group in access through vba

2019-02-14 19:58发布

问题:

I have a module of VBA code in access that creates 4 new tables and adds them to the database. I would like to add in a part at the end where they are organized in the navigation pane through custom groups so that way they are all organized. Would this be possible through vba?

EDIT:

I don't want the tables to be in the unassigned objects group. I want to change the name of that group through VBA.

回答1:

EDIT: Added more code to add other object types to the custom Nav group.

The following code will assign tables to your custom Navigation Group.

WARNING!! There is a 'refresh' issue of table 'MSysNavPaneObjectIDs' that I am still trying to resolve. If you create a new table and then try to add to your group - sometimes it works on the first try, other times it fails but will work after a delay (sometimes up to five or ten minutes!)

At this moment, I got around the issue (when it fails) by reading info from table 'MSysObjects', then adding a new record to 'MSysNavPaneObjectIDs'.

The code below simply creates five small tables and adds to Nav Group 'Clients'

Modify the code to use your Group name / table names.

'>>> CHANGE FOLLOWING LINE TO YOUR CUSTOM NAME
    ' Pass the Nav Group, Object Name, Object Type
    strResult = SetNavGroup("Clients", strTableName, "Query")
    Debug.Print strResult

For i = 1 To 5
    strTableName = "0000" & i
    strSQL = "CREATE TABLE " & strTableName & " (PayEmpID INT, PayDate Date);"

回答2:

Thanks a lot for your code, I had to modify it a little on my specific case due to the issue on the refresh of the table. In fact I am recreating a table (deleting the old one before). As the MSysNavPaneObjectIDs does not refresh, the old ID is kept inside.

e.g. let's use a table tmpFoo that I want to put in a group TEMP.

tmpFoo is already in group TEMP. TEMP has ID 1 and tmpFoo has ID 1000 Then I delete tmpFoo, and immediately recreate tmpFoo. tmpFoo is now in 'Unassigned Objects'.

In MSysObjects, ID of tmpFoo is now 1100, but in MSysNavPaneObjectIDs the table is not refreshed and the ID of tmpFoo here is still 1000.

In this case, in the table MSysNavPaneGroupToObjects a link between TEMP(1) and tmpFoo(1000) is created => Nothing happen as ID 1000 does not exists anymore in MSysObjects.

So, the modified code below get in all cases ID from MSysObjects, then check if the ID exists in MSysNavPaneObjectIDs.

If not, add the line, then use the same ID to add it to MSysNavPaneGroupToObjects.

In this way seems I do not have any refresh issue (adding Application.RefreshDatabaseWindow in the upper function). Thanks again Wayne,
