GDI Leak (TD63) - MDI - Ribbonmenus with icons

[wwasilew]

Hi,

we have founded a GDI leak by using of MDI - window and variable bMenuBarAsRibbonBar = TRUE.
When the menus contains some icons, then the count of GDI - Objects in the memory grows up, every time a form is opened or activated.
The GDI Objects will be no more released, not by closing of forms and not by closing of debug mode.
Only when the apt is closed, will they released.

We have a big MDI - application with a lot of Formwindows and with a lot of Icons.
It does not take long a time, and we have a follow picture in the task manager:

By 10000 GDI - Objects in memory crashs the app or stops responding.

It's really very very critical issue for us and we need a quick help with this.
This existing in TD 63 (SP1) and TD 63 (UPD2).
It works with TD6.1.

We use Windows 7 - SP1 64 Bit (German).
Testcase is atached. Please start the apt and activate alternately both formwindows and check the count of GDI in task manager.
Or press the button "Loop" and wait

Sorry for my english

I will test this out and get back to you.

That's true.
We have a MDI Window app also and the GDI-Objects grows every time we open a form windows as child or close it.

Any news about this?

Sorry for the delay.

I tried to test this today and discovered that while you are reporting a problem with icons on a ribbonmenu, your sample that you gave did not actually contain any icons; just references to them, i.e. icons\paste.ico.

Can you please give me the icons that should go with the example file?

Thanks!

Sorry Mike,

i 've forgot the icons...

the new zip with icons - dir is attached.

Hi,

I've just tested this with a pre-release of TD6.3 SP1 Update 1 and when using GDIView, the total GDI count stays at exactly what the count was when the form was generated. I tried swapping from one to the other many times, then ran the 'loop' test 6 times and the GDI count remained constant.

I think this one in squashed with Update 1.

Best regards,

Hi Mike,

that's good news! But where can i get the Update 1 for TD 6.3SP1?
This is not by downloads on the Gupta website.

[Mike Vandine]

That's because it's not released yet. I have a bit of advantage.

I could be a couple more weeks for the final release. We're verifying bug fixes, etc.

Best regards,
