Problem with Dialog, memory?

Riccardo · Post by **Riccardo** » Wed Dec 13, 2006 9:32 am

In my application after open and close many times dialogs (with many objects tree, btnbmp, txbrowse ecc) happens that the same dialogs are not created and I've to restart the application and the dialogs are well created.

Is due to lack of memory?
How is possible to solve the problem?

Riccardo,

Do you use bitmaps, fonts, brushes ? (GDI objects)

If yes, how do you manage them ?

We use Fonts and Bitmaps, calling end() method after close the dialog.
We use folder and a lot of TBtnBmp.

Don't use Brushes.

Thank you.

Riccardo,

The problem you describe is a typicall problem when GDI objects are not properly released. Could you provide some samples of your dialogs so we may review their code ? Thanks,

Richard,

That error happens when you are consuming a lot of GDI resources without properly releasing them. There are several available tools to check the consumed GDI resources:
