Symptom

PowerBuilder might fail to open dialogs.

When you install the Windows Update (KB3057839), which includes the following fix for Windows Vista:

MS15-060: Vulnerability in Microsoft common controls could allow remote code execution.

Environment

Windows Vista with Windows Aero enabled

PowerBuilder

Reproducing the Issue

1.  Create a dialog to call the setRedraw in the open events.

Open event of w_dialog

--------------------------------------------

event open;

integer ret

This.SetRedraw(False)

ddlb_1.AddItem("123")

ddlb_1.AddItem("456")

ret = This.SetRedraw(True)

end event

Open a dialog

open w_dialog

Cause

This problem is not a PowerBuilder issue.

It happens because PowerScript of setRedraw will call setRedraw of the Windows API.

Resolution

The following workarounds can help on this situation:

Turn off Windos Aero

Uninstall KB3059317

Change the property "Visible" of dialog to "true"

Install KB3070102, which contains the following fix:  MS15-073: Vulnerabilities in Windows Kernel-Mode Driver Could Allow Elevation of Privilege
