Dissapearing Menus

[John Stevens]

I have an application that is loaded across a network. Occasionally some of the computes loose the toolbar.

Any idea what would cause this?

John,

Some of the computers loose the tool bar; is this in view or design mode?

Quite often, while in design mode, the tool bar does take a hike and doees not come back. The only solution that I'm aware of is to close out the app and open it again.

If it's happening in view mode, I've not heard of that problem before. Perhaps a search for disappearing tool bar my yeild additional info.

It is happening in view mode. The toolbar itself doesn't actually disappear, it is still there, but the buttons are gone (except for one half of one of the icons on the far left end, and you can't click on that).

I will continue my search for an answer, any other ideas, please let me know.

Thanks!

try compacting the database and then refresh the shadows

John,

I tried that but it didn't help. Any other ideas?

If you're using ui_freeze()you might try doing without it.
If that doesn't work you might try calling the menubar
a second time when you initialize the form. If you've
got a lot of graphics on the form including large buttons
I'de be suspicious that the systems just plain overworked.

Good luck.

John,

If the toolbar is custom designed, any of the items in the form or a report can vanish or become corrupted. The item can vanish when the Form's item index becomes corrupted. Usually this problem can be resolved by running a Database Compact especially if you have deleted some form items. This can rebuild the item indexes for the problem form and make objects visible again.

If this still doesn't work, the form item may be corrupted. Usually the items entry is still readable, but the associated compiled binary code for it is corrupted and the item won't run properly.
Usually the solution is to make a copy of the form or report with the corruption and then delete pieces until the remaining portion of the form starts to work again. You then delete this one item from a fresh copy, patch the form and save it.

On more complicated database designs, it's wise to work with copies of forms and reports rather than to risk corruption of the only good working copy.

Tom,

I'm not using ui_freeze(), but your idea of calling the toolbar again doesn't sound like a bad idea.

How would I go about doing this?

Thanks

Scott,

The xbasic command to load a toolbar is

formmname.toolbar = "toolbar name"

If you want to reload a menu, use

formname.drop_down_menu = "menu name"

I have seen a case where the menu disappears when switching from a dialog back to the calling form, but I have not had a problem with toolbars.

Another consideration is that refresh shadow may not have completely transfered all the correct data. If in doubt, try copying the database .alb, .alm, .alx files from the server to the terminal manually. This will insure that the terminal has the same menus and toolbars available since they are saved in these files. Do NOT copy the .adb file. If you want the tables to be current, copy the .ddd, .ddm, .ddx files for each table from the server to the terminal. This is essentially what refresh_shadow() is supposed to do. Unfortunately, like many others, I have found refresh_shadow() to be unreliable on occasion.
