Upgrade Issues with MFC Controls

Known upgrade issues are listed below. Report any undocumented upgrade issues to CA Technical Support if they cause a problem in your application.

• Disabled text color. When MFC controls are disabled, the text displays in the Windows standard color (typically, light gray). The Text Color property is ignored when controls are disabled. Note that for edit controls you can use the combination of properties

  Mode=Read-only
  

  and

  Disabled=No
  

  to define a read-only edit control that does support the Text Color property.

• Combo box size. Unlike other control types, the size of the edit control portion of a combo box cannot be changed directly; it is determined by the font size of the text within the control. You can change the size of the edit portion at design time but it is ignored at run time. Instead, changing the size of the edit portion at design time, changes the size of the drop-down list at run time.
• Transparency. MFC controls do not fully support transparency. This may change the appearance of panels in cases where controls overlap.
• z-order. The z-order of MFC controls is reversed compared to the default z-order of Winwidgets controls. This may impact some panel designs that rely upon overlapping controls.

Note: To allow the z-order of design time controls to more closely match the run time, set the Clip Control property to Yes for each control concerned. This is useful when working with overlapping controls such as a frame within a frame.
