FYI,

We have one window in which someone put 20+ u_dw controls and some other controls. On opening this window and doing anything, powerbuilder would hang / crash (especially when trying to save). The "normal" way of doing things would have been to place those datawindow controls on a/several userobjects or use only a few controls and assign datastore content to it, but ...

The only way I was able to work with the window, was by taking out all of the dataobject assignments in the properties and assign those in the constructor events.

Maybe nothing to do with the problem here, except for "reaching to the limits" of used dw controls on a window.

Hi

We have large multi tab applications but have not experienced the problems that you are experiencing. Mu gut is telling me that it is more likely a coding issue somewhere that is using resources and not releasing them. PB is generally very well behaved  and only consumes resources because of your own code and not due to PB itself.

When ever we have been involved in diagnosing these sorts of issues we have found issues in the code that we can fix and cut the problems down. I suggest you look at you code and make sure objects that are being created are properly destroyed and garbage collection is run.

Hi Marian;

   If your App has a lot of DataStores .... have you tries this:

Create a PB.INI file in the same folder as your App (or its .EXE).

1. Add the following section & entry to your PB.INI file, as follows:

• [DataStore Behavior]
• UseHwnd=no

HTH
