To use MessageDlg, #include the header file dialogs.hpp.

MessageDlg("You want me to give you this message?", //Message   mtConfirmation, //Message type   TMsgDlgButtons() << mbYes << mbNo, //Buttons   0); //Help Context

 

 

 

 

 

Use of MessageDlg

 

---

const int returnValue = MessageDlg(AnsiString Msg, //Message   TMsgDlgType DlgType, //Message type   TMsgDlgButtons Buttons, //Buttons   int HelpCtx); //Help context

 

Possible return values are: mrOK, mrCancel, mrYes, mrNo, mrAbort, mrRetry, mrIgnore

Possible message dialog types are:

 

---

enum TMsgDlgType { mtWarning, mtError, mtInformation, mtConfirmation, myCustom };

 

Possible buttons are:

 

---

enum TMsgDlgBtn { mbYes, mbNo, mbOK, mbCancel, mbAbort, mbRetry, mbIgnore, mbAll, mbNoToAll, mbYesToAll, mbHelp };

 

Because TMsgDlgButtons is a set, you use it e.g. by:

 

---

TMsgDlgButtons() << mbYes << mbNo; //Etcetera
