Can I disable the "Zoom" key for one form - or all

As for completely preventing a User from using the Zoom functionality, this is possible. It is a matter of permissions.

There is a System object - 5330 Tools, Zoom - which controls the access of User Groups to this tool.
If a User does not belong to a Role with permission to access this Object, he will not be able to use the Zoom window - it will be disabled.


On your original question, there is no way to deny Zoom access on a selective basis. It is an Application wide setting controled only by permissions.
Unless there is someone really clever [;)] out there who can show us how... [:0]

Actually Nelson, it can be done (so does that mean I am someone really clever[:I]), but it is not straight forward. Also it is table dependant, not form, since the Ctrl+F8 goes straight to the Table with no reference to the Form.

All you need is a field in the table with a caption class. When you zoom on the table, a call is made to codeunit 1, and you can add code in here to prevent the field from displaying.

I suggest to create your own field, "CheckForF8" and modify Codeunit 1

CaptionClassTranslate(Language : Integer;CaptionExpr : Text[80]) : Text[80]
CommaPosition := STRPOS(CaptionExpr,',');
IF (CommaPosition > 0) THEN BEGIN
  CaptionArea := COPYSTR(CaptionExpr,1,CommaPosition - 1);
  CaptionRef := COPYSTR(CaptionExpr,CommaPosition + 1);
  CASE CaptionArea OF
    '1' : EXIT(DimCaptionClassTranslate(Language,CaptionRef));
    '2' : EXIT(VATCaptionClassTranslate(Language,CaptionRef));
    //>> Start Zoom check
    '50000' : RunCtrlF8Check(CaptionRef);
  END;
END;
EXIT('');

Then just pass a paramater like '50000,27' to the CaptiionClassParamater. THe code will be called on Zoom, or Table Run from the designer. You can prevent a super user from viewing a table like this.

THis is really a Tips and Tricks Item, and you can use it for lots of things, like high level table security.

Hope it helps, let me know.

So, David, where can I send you the cigar?

Cigar ... Lets make it a bottle of fine Porto, and we can share it watching a sun set one evening [:)]

I'm afraid I'm not a wine guy myself - I prefer Weissbier...[:D]
But anyway, it's a deal if you ever come visit.

Humm, this reminds me I haven't yet voted on the beer thread!!! [8D]

David,

Can you explain further how to implement this please?

Thanks.

On a form you can achieve this by adding a Menu Button Item with Ctrl+F8 as ShortCutKey. If you don't assign any Action or Code to that menu item nothing will happen when Ctrl+F8 is pressed.

Am I clever too? [:D]

You are a genius [:D]

Only thing is, this disables it for all users. Then youl'd have to disable the button for users that are allowed to zoom.[:I]

Lloyd,

What is the part in David's explanation that you do not understand?

Uh. It could work. If users can't work with the menu. [:D] You can zoom if you go to Extra, Zoom in the menu...
