Button limitation in Forms?

Hi, I'm building a new app using Desktop 4.1.5d and Forms 4.1.5; this will be used on a tablet PC under Desktop and the greater screen size (1024x600) means I have got carried away using Action buttons (which I really appreciate). At the moment I am only putting together an initial template form which will then be copied and each copy customised (some buttons removed, others added, data sources changed, etc as needed - but it means I keep the same structure throughout.
I now have over 80 buttons on the one form, each set to "append caption to value", but, suddenly, I can now no longer copy and paste any buttons nor can I add any new buttons to this form - although I can add to other forms in the same database.
Is there a limit to the number of buttons per form? Is there anything I can do to overcome this (changing sizes, colours, whatever)? At present the database itself only has 30 or so fields but will have quite a few more (but I know I am working to a 100 field limitation)
I do realise I may be trying to use HDB in a way it possibly wasn't envisaged in its early days, but having tried to do what I wanted on PDA's, I gave up because of the limited screen sizes and have possibly now tried to put too much on the screen and may therefore have to redesign!

Hi there,

There is indeed a limit in the buttons. I thought it was 100, but perhaps it's just 80. Never thought someone would actually hit that limit to be honest. I can easily bump that number up on the Windows side, but not so easily on the device side- since there is a memory limitation there. If just changing it on the windows side would do it for you, let me know, and I'll make that change for the next version.

Thanks Dave,
I would really welcome that (+ perhaps an increase to the number of fields??). I have yet to find anything to quite match HDB for custom built touch screen use on tablet pc's (especially where there is PDA to tablet path of existing apps). Without wishing to hold you to a date for the next Windows update, do you have one in mind?

In a response to an earlier post, you also mentioned the possibility of an auto-save for the Windows version - might this also be included? I'd really love to see an action button to save (eg, "Save (to disk) and create new record") without having to "save and close", click save icon then start again - which I do frequently because I still don't fully trust Windows, especially on a fragile handheld device - even with W7, hard lessons learnt from early versions of Windows are impossible to forget.

2010 is reputed to be the 'year of the tablet pc' but I only see a few business-type programs out there that really exploit the benefits of touch screen - HanDBase for Windows is one of them, though, if I may say this kindly, could benefit from moving on a bit from some of the limitations of the smaller screen devices. I fully realise how hard this is now with such a multitude of different devices and OS's now out there, though (Palm OS was a lot simpler!).

Hi Doug,

As you have guessed, I won't have a date for the release, but if you email me I can send you the build with this ahead of the actual release. My email is listed below.

Re: number of fields- that's not something I can change- it's part of the database structure and thus the 100 field limit will remain until we update the structure (perhaps in the next few years, but not this year for sure).

Hope this helps!

Hi all,

Just as an update- when looking into this I discovered I was incorrect on my previous assessment. As there is a global limit of 100 controls/resources on any form within the forms structure we have, I cannot easily up this limit. This limit supercedes the other one we spoke of before, so changing that one won't really help since the format itself is limited to 100 controls.

Sorry about that mixup!
