AMessage	string

Message dialog box content. The AMessage parameter value initializes the created form’s Message property.

The AMessage parameter supports a set of BBCode-inspired tags that allow you to format message box content.

| | AHyperlinkClickProc | TdxMessageDialogHyperlinkClickDelegate |

Optional. Specifies a procedure that handles a click on a hyperlink within the displayed message. The AHyperlinkClickProc parameter value initializes the HyperlinkClickProc property of the created message dialog box form.

You can define a click handler procedure to identify the clicked hyperlink and prevent certain links from being activated.

Tip

Refer to the TdxMessageDialogHyperlinkClickDelegate procedural type description for detailed information and a code example.

| | AShowHyperlinkHintProc | TdxMessageDialogShowHyperlinkHintDelegate |

Optional. Specifies a procedure that handles a hyperlink hint display event. The AShowHyperlinkHintProc parameter value initializes the ShowHyperlinkHintProc property of the created message dialog box form.

You can define a hyperlink hint handler procedure to change the predefined hint message (the hyperlink target URI) depending on certain conditions in your application.

Tip

Refer to the TdxMessageDialogShowHyperlinkHintDelegate procedural type description for detailed information and a code example.

Remarks

Call the dxShowMessage procedure to open a generic message dialog box without a system icon. The created message dialog box uses the application name as a title.
