Font Dialog Initialization Flags

Before calling ChooseFont, the Flags member of the CHOOSEFONT structure must specify CF_SCREENFONTS, CF_PRINTERFONTS, or CF_BOTH, to indicate whether the dialog box should list screen fonts, printer fonts, or both. If you specify CF_PRINTERFONTS or CF_BOTH, the hDC member of the CHOOSEFONT structure must specify a handle to a device context for the printer.

You can use the Flags member to enable or disable some of the dialog box controls, and you can use the Flags member in conjunction with other CHOOSEFONT members to control the initial values of some controls.

To display the controls that allow the user to select strikeout, underline, and color options

Set the CF_EFFECTS flag. You can use the rgbColors member of the CHOOSEFONT structure to specify an initial font color.

To specify the initial values of the Font, Font Style, Size, Strikeout, and Underline dialog box controls

Set the CF_INITTOLOGFONTSTRUCT flag to use members of the LOGFONT structure to specify the initial values.
You can also use the CF_NOFACESEL, CF_NOSTYLESEL, and CF_NOSIZESEL flags to selectively prevent the dialog box from displaying initial values for the corresponding controls. This is useful when working with a selection of text that has more than one typeface, style, or point size. These values will also be set in Flags when ChooseFont returns if the user did not select a corresponding value.

To initialize the Font Style control to a specified style name

Set the CF_USESTYLE flag and use the lpszStyle member to specify the style name.

To display the Apply button

Set the CF_APPLY flag and provide a hook procedure to process WM_COMMAND messages for the Apply button. The hook procedure can send the WM_CHOOSEFONT_GETLOGFONT message to the dialog box to retrieve the address of the LOGFONT structure that contains the current selections for the font.

To display the Help button

Set the CF_SHOWHELP flag. The hwndOwner member must identify the window to receive the HELPMSGSTRING registered message when the user clicks the Help button.

To restrict the fonts the dialog box displays

Set any combination of the CF_TTONLY, CF_FIXEDPITCHONLY, CF_NOVECTORFONTS, CF_NOVERTFONTS, CF_SCALABLEONLY, and CF_WYSIWYG flags. You can also restrict the available styles, point sizes, and effects the dialog box displays for some fonts by using the CF_NOSIMULATIONS value.

To restrict the typeface names, styles, and point sizes that the user can specify

Set the CF_FORCEFONTEXIST flag to restrict the user to specifying only valid typeface names, styles, and point sizes.
Set the CF_LIMITSIZE flag to restrict the user to specifying point sizes in the range specified by the nSizeMin and nSizeMax members.

To restrict or disable the Scripts combo box

Set the CF_NOSCRIPTSEL flag to disable the Scripts combo box, or set the CF_SELECTSCRIPT flag to restrict selections in the Scripts combo box to a specified character set.

    Nostalgia .Net     .Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native.
