DOCUMENT:Q257789 20-AUG-2001 [vbwin] TITLE :FIX: Data Source Is Not Updated When PropertyChanged Is Called PRODUCT :Microsoft Visual Basic for Windows PROD/VER:WINDOWS:6.0 OPER/SYS: KEYWORDS:kbGrpDSVBDB kbDSupport kbVS600sp4fix kbVS600sp5fix ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Visual Basic Professional Edition for Windows, version 6.0 - Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 ------------------------------------------------------------------------------- SYMPTOMS ======== A Visual Basic 6.0 Standard EXE project contains several data-bound UserControls of the same type on a form. One property of the UserControl is bound to an OLE DB Simple data source at run-time after the form is loaded. The bindings are added by looping through the Form.Controls collection. The property attribute is set to "immediate update" at UserControl design time. In the Visual Basic integrated development environment (IDE), changes to the bound properties are correctly reflected back to the underlying data source as soon as the PropertyChanged method is called. However, when you run the compiled EXE, the underlying data source of the control is only updated when the control focus is moved to any other control on the form. RESOLUTION ========== To resolve this problem, install the latest service pack for Visual Studio 6.0. STATUS ====== Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in the latest service pack for Visual Studio 6.0.
