The information in this article applies to:
SYMPTOMSWhen the ChooseColor() API is called to display the custom color selection dialog box in an application that is globally subclassing edit controls, an application error (The memory could not be read) occurs in the application. CAUSECertain messages are sent to this dialog before WM_INITDIALOG. These messages manipulate the dialog's edit controls. However, these messages assume the standard system edit control and act accordingly, thus causing the problem. RESOLUTIONTo avoid this error, applications that use a global customized edit control should use a superclassed edit control. STATUSMicrosoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
