Code Example: Create a Message Box with Custom Button Captions

The following code example calls the dxCreateMessageDialog function to create a message box with three buttons and customizes their captions:

Delphi

uses dxMessageDialog;
// ...
var
  ADialog: TdxMessageDialogForm;
  AMessage: string;
begin
  AMessage := 'One or more margins are set outside the printable area of the page.' + #13#10 +
    'Click the [B]Fix[/B] button to increase these margins.';
  ADialog := dxCreateMessageDialog(AMessage, mtWarning, mbYesNoCancel);
  try
    ADialog.FindButton(mbYes).Caption := 'Fix';
    ADialog.FindButton(mbNo).Caption := 'Restore Original';
    ADialog.FindButton(mbCancel).Caption := 'Close';

    ADialog.AlignButtons;  // Recalculates the button layout
    ADialog.ShowModal;     // Invokes the form as a modal dialog
  finally
    ADialog.Free;  // Releases the message box form once a user closes it
  end;
end;

C++

#include "dxMessageDialog.hpp"
// ...
  TdxMessageDialogForm *ADialog;
  UnicodeString AMessage = "One or more margins are set outside the printable area of the page.\n" +
    "Click the [B]Fix[/B] button to increase these margins.";
  ADialog = dxCreateMessageDialog(AMessage, wtWarning, mbYesNoCancel);
  try
  {
    ADialog->FindButton(mbYes)->Caption = "Fix";
    ADialog->FindButton(mbNo)->Caption = "Restore Original";
    ADialog->FindButton(mbCancel)->Caption = "Close";

    ADialog->AlignButtons();  // Recalculates the button layout
    ADialog->ShowModal();     // Invokes the form as a modal dialog
  }
  __finally
  {
    delete ADialog;  // Releases the message box form once a user closes it
  }

Limitation

The dxUseStandardMessageDialogs global variable has no effect on dxCreateMessageDialog function calls.
