BUG: Edit Control's Number Style Check Box Won't Stay Selected

The information in this article applies to:

• The Resource Editor included with: Microsoft Visual C++, 32-bit Edition, versions 4.0, 4.1, 4.2

SYMPTOMS

Edit controls that have previously been given the ES_NUMBER style do not have the corresponding Number check box selected under the style properties when they are loaded into the resource editor.

CAUSE

This is a display problem in the resource editor. Although the resouce editor shows the Number check box as clear, rebuilding the application or opening the .rc file in text mode will confirm that the ES_NUMBER style is still being applied to the edit control. However, if the dialog box containing the control is edited and saved, the ES_NUMBER property will no longer be applied to the edit control unless you again select the Number check box.

RESOLUTION

Select the Number check box for edit controls that should have the ES_NUMBER style each time you modify the dialog box containing the edit control.

STATUS

Microsoft 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.

MORE INFORMATION

The ES_NUMBER style first available in Windows 95 restricts input to the edit control to digits only. If an edit control has this style under Windows NT 3.51, you can still enter characters other than numbers. However, under Windows 95, an edit control with this style accepts digits only.
