Introduction

Another MessageBox :The CodeProject site contains more solutions as an extension to the standard MessageBox. So why another one? You may ask. I don't develop classes unless I feel there's a real need for them in my own projects. For a long time I've used "XMessageBox - A reverse-engineered MessageBox()" class by Hans Dietrich. That is a nice class and I am thankful to him for his work. However, all things comes an end. This class has ceased to satisfy me. I wished to have a class that would allow me to control the colors of the message text and background. I had already developed, and successfully tested, a class for drawing pseudo-HTML in my own classes CPPToolTip and CPPHtmlStatic. So, the solution for drawing colored text was easily found. For the additional features of this class, I relied on already available classes on CodeProject. Many thanks to all those who have helped me in creating this class, in particular to the authors of these classes published on CodeProject:

• XMessageBox by Hans Dietrich.
• TCX Message Box by Thales P. Carvalho.
• Enhanced MFC message boxes by Michael P. Mehl

PPMessageBox

Remarks

The PPMessageBox function creates, displays, and operates a message box. The message box contains an application-defined message and title, plus any combination of predefined icons and push buttons.

When you use a system-modal message box to indicate that the system is low on memory, the strings pointed to by the lpszText and lpszCaption members of the PPMSGBOXPARAMS structure should not be taken from a resource file, because an attempt to load the resource may fail.

If you create a message box while a dialog box is present, use a handle to the dialog box as the hWnd parameter. The hWndparameter should not identify a child window, such as a control in a dialog box.

PPMSGBOXPARAMS structure

The PPMSGBOXPARAMS structure contains information used to display a message box. The PPMessageBox and PPMesssageBoxIndirect functions uses this structure.

typedef struct PPMSGBOXPARAMS
{
  //MessageBox area
  HWND hParentWnd;
  HINSTANCE hInstanceStrings;
  HINSTANCE hInstanceIcons;
  LPCTSTR lpszCaption;
  LPCTSTR lpszModuleName;
  LPCTSTR lpszCompanyName;
  int nLine;
  DWORD dwReportMsgID;
  PPMSGBOXAREA_BK pMsgBoxBk;
 
  //Header area
  int nHeaderHeight;
  LPCTSTR lpszHeaderText;
  PPMSGBOXAREA_BK pHeaderBk;
 
  //Message area
  LPCTSTR lpszText;
 
  //Control area
  int nControlsAlign;
  DWORD dwStyle;
  PPMSGBOXAREA_BK pControlBk;
 
  //MoreInfo area
  LPCTSTR lpszMoreInfo;
  PPMSGBOXAREA_BK pMoreInfoBk;
 
  int nTimeoutSeconds;
  int nDisabledSeconds;
  BOOL bDisableAllCtrls;
  DWORD dwContextHelpID;
  DWORD dwUserIconID;
  LPCTSTR lpszCustomButtons;
  LPCTSTR lpszCheckBoxText;

  mapLocalBtnText * pLocalBtnText;
} PPMSGBOXPARAMS;

Members

• hParentWnd

  Handle to the owner window. This member can be NULL.

• hInstanceString

  Handle to the module that contains the string resource identified by the lpszText, lpszCaption and other string members.

• hInstanceIcons

  Handle to the module that contains the icon resource identified by the lpszIcon member.

• lpszCaption

  Pointer to a null-terminated string, that contains the message box title. If this member is NULL, the default title Error is used.

• lpszModuleName

  Specifies the source module name for the application. This may be the actual source module name (for example, the name returned by the __FILE__ macro) or a name meaningful to the context (for example, "ConfirmFileDelete"). This is used when saving the "Do Not Ask/Tell" checkbox state in the registry or ini file.

  It is up to the application to manage this registry entry. If it is necessary to clear out this entry each time the application starts up, the application must include the code to do this. All key/value pairs for XMessageBox are stored in the registry under HKEY_CURRENT_USER\Software\CompanyName\AppName\PPMessageBox. If an ini file is being used, the checkbox state will be saved in the file PPMessageBox.ini, in the app's directory.

  When the message box is displayed, if lpszModule has been specified in the XMSGBOXPARAMS struct, the message box will only be displayed if the registry entry does not exist. If the message box is displayed, and the user checks the "Do Not Ask/Tell" checkbox, the checkbox state will be saved in the registry.

• lpszCompanyName

  Specifies the company name for the application. This is used when saving the "Do Not Ask/Tell" checkbox state in the registry or ini file.

• nLine

  Specifies the source module line number for the application. This is used when saving the "Do Not Ask/Tell" checkbox state in registry. Note that regardless of whether the lpszModule string is encoded, the line number will not be encoded.

• dwReportMsgID

  Specifies the message to be sent by click on the Report button.

• pMsgBoxBk

  PPMSGBOXAREA_BK structure that contains information used to display the background of the all message box.

• nHeaderHeight

  The minimal height of the message box header.

  PPMSGBOXAREA_BK structure that contains information used to display the background of the header area of the message box.

• lpszText

  Pointer to a null-terminated string, or the identifier of a string resource passed to the MAKEINTRESOURCE macro, that contains the message to be displayed. This string may be in a HTML-like format.

• nControlsAlign

  Value that specifies the horizontal alignment of the button in the message box. This member can be one of the following values: PPMSGBOX_ALIGN_LEFT, PPMSGBOX_ALIGN_RIGHT or PPMSGBOX_ALIGN_CENTER.

• dwStyle

  Specifies the contents and behavior of the dialog box. This member can be a combination of flags described for the dwStyle parameter of the PPMessageBox function.

  In addition, you can specify the MB_USERICON flag if you want the message box to display the icon specified by the lpszIcon member.

  Flag that indicates whether default button is being disabled (FALSE) or all buttons of the message box are being disabled (TRUE). The 'Help', 'Report' and 'MoreInfo' buttons are never disabled.

• dwContextHelpID

  Identifies a help context. If a help event occurs, this value is specified in the HELPINFO structure that the message box sends to the owner window or callback function.

• lpszIcon

  Identifies an icon resource. This parameter can be either a null-terminated string or an integer resource identifier passed to the MAKEINTRESOURCE macro.

  To load one of the standard system-defined icons, set the hInstance member to NULL and zIcon to one of the values listed with the LoadIcon function.

  This member is ignored if the dwStyle member does not specify the MBUSERICON flag.

• lpszCustomButtons

  Pointer to a null-terminated string, or the identifier of a string resource passed to the MAKEINTRESOURCE macro, that contains the list of the custom button captions. This string has the format "Custom 1\nCustom 2\nCustom 3\nCustom 4". NULL if custom buttons are not used.

  Up to four buttons may be specified. When a custom button is clicked, it will return the value IDCUSTOM1, IDCUSTOM2, etc. When custom buttons are specified, no other buttons will be displayed (except 'Help', 'Report' and 'MoreInfo' buttons. These buttons may be displayed anyway).

• lpszCheckBoxText

  Pointer to a null-terminated string, or the identifier of a string resource passed to the MAKEINTRESOURCE macro, that contains the checkbox caption. You can change a checkbox caption for each message box. If this parameter is NULL, then a checkbox caption is retrieved from the map specified by pLocalBtnText member or from the resources. If that parameter is also NULL, the check box caption will default to 'Do not show again'.

• pLocalBtnText

  Pointer to the map that contains pointer to a null-terminated string, or the identifier of a string resource passed to the MAKEINTRESOURCE macro that contains the button captions. Key of the map is the button ID (for example: IDOK, IDCANCEL, IDYES, MB_CHECKBOX etc.).
