How many control per dialog?

[dutch]

Dear All,

I try to put button, the limitation is 650 buttons. It will crash (got error), if it is greater than 650 buttons.
How many the limitation of controls per dialog?

Thanks in advance for any suggestion.

Dear Dutch,

FWH does not impose any limit on that, so I guess that you are reaching the limit of your Win32 app default HEAP.

You may try to increase the heap using the linker flag /HEAP when linking the EXE:

/HEAP: 0x10000, 0x1000

Please try to increase those values.

Please post here the example you are testing to review it as maybe it is a different issue

[Antonio Linares]

Please try to build your PRG using FWH 64 as it should solve it also

Dear Antonio,

I use UEStudio. Where do I set "/HEAP: 0x10000, 0x1000"? I try to add in [Settings] but nothing change.

What C compiler are you using ?

Dutch,

Wow, 650 buttons! Maybe you should re-think your interface design. Try doing a Google search for "software dialogs," and select "images." The most buttons I saw on any dialog was five. 650 buttons is way too complex to understand.

I think the most complex dialog I ever did was with 6 folders and four buttons, Print Help Cancel OK. The 4 buttons were outside the folders--they applied to all of the folders.

If you need 650 choices maybe you should consider a drop-down list with two buttons, Cancel OK.

[dutch]

Dear James,

This is what I do. The hotel room planner, sometime it has more 650 booking in 1 dialog to show.

Just curious...

Why not use the cell content of the browse for activating a action ?

You prefer a button action. Is this because the buttons seems to be on top en overlapping the cells ?

[dutch]

Dear Richard,

Yes, of course. I need button overlap the grid. Because it is the guest stay noon 1st day to noon 2nd day. It is not browse, it is sayline().

Sometime I try to find Grantt library to make like this picture but not found. If you have any idea, most welcome.
Thanks for your question.

[Marc Venken]

I use a Xbrowse for something simular and no need for extra libs that are not included in standard FW (so also no issues from older libs)

[Silvio.Falconi]

wich class you use for this planner ?

Can you publish a small test sample ?

[James Bott]

Dutch,

This is what I do. The hotel room planner

OK, that is not a typical dialog. I can't really tell from the picture if it is actually a dialog or a window?

Was it working until just recently, or is this a new project or design?

You should be able to find the maximum controls you can have on a dialog by just creating a dialog and then adding controls one at a time in a loop, until it crashes.

[Antonio Linares]

Dear Dutch,

Google results:

You can change the heap sizes the linker uses via the -GH flag for ilink32 or ilink64. Use -GH<heapname>=size to allocate a larger heap or multiple heaps. For example, to link the release version of the DLL OWLNext library, internal C++Builder developers use -GHinfo=0x13000000

https://docwiki.embarcadero.com/RADStudio/Sydney/en/Handling_Linker_Out_of_Memory_Errors

My advise is to stop using Borland and start using Microsoft Visual Community. Borland C compiler is the slowest of all and it does not compare at all to current Microsoft C compiler so powerful tools. You should consider migrating to MSVC

Anyhow I am not sure yet that this may solve your issue but it is worth to try it

[Otto]

Dear Antonio,
Is there a step-by-step guide on how to switch to MSVC.
I use UEStudio and xHarbour to compile.
Thank you very much in advance.
Best regards,
Otto
