( C++ VCL ) MessageDlg

A dialog posing a question that can be answered by yes/no/cancel/etc.

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

Example

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
