dxShowMessage(string,TdxMessageDialogHyperlinkClickDelegate,TdxMessageDialogShowHyperlinkHintDelegate,TdxMessageDialogHintedTextClickDelegate,TdxMessageDialogShowTextHintDelegate) Method

Opens a generic message dialog box with an OK button.

Declaration

procedure dxShowMessage(const AMessage: string; const AHyperlinkClickProc: TdxMessageDialogHyperlinkClickDelegate = nil; const AShowHyperlinkHintProc: TdxMessageDialogShowHyperlinkHintDelegate = nil; const AHintedTextClickProc: TdxMessageDialogHintedTextClickDelegate = nil; const AShowTextHintProc: TdxMessageDialogShowTextHintDelegate = nil);

Parameters

Name	Type	Description
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. A procedure that handles clicks on hyperlinks in the displayed message. For example, use this procedure to identify the clicked hyperlink and prevent specific links from being activated. This parameter value initializes the HyperlinkClickProc property of the created message dialog box form. Refer to the procedural type description for detailed information and a code example: TdxMessageDialogHyperlinkClickDelegate.
AShowHyperlinkHintProc	TdxMessageDialogShowHyperlinkHintDelegate	Optional. A procedure that handles hyperlink hint display events. For example, use this procedure to modify the predefined hint message (the hyperlink target URI) based on conditions in your application. This parameter value initializes the ShowHyperlinkHintProc property of the created message dialog box form. Refer to the procedural type description for detailed information and a code example: TdxMessageDialogShowHyperlinkHintDelegate
AHintedTextClickProc	TdxMessageDialogHintedTextClickDelegate	Optional. A procedure that handles clicks on hint-marked text ranges in the displayed message. For example, use this procedure to identify the clicked text range. This parameter value initializes the HintedTextClickProc property of the created message dialog box form. Refer to the procedural type description for detailed information and a code example: TdxMessageDialogHintedTextClickDelegate.
AShowTextHintProc	TdxMessageDialogShowTextHintDelegate	Optional. A procedure that handles hint display events for hint-marked text ranges enclosed between [HINT] and [\HINT] tags. For example, use this procedure to modify the hint message based on conditions in your application. This parameter value initializes the ShowTextHintProc property of the created message dialog box form. Refer to the procedural type description for detailed information and a code example: TdxMessageDialogShowTextHintDelegate.

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.

Code Example: Display a Generic Message Dialog

The code example in this section displays a generic message dialog with a formatted message and a single OK button. The message dialog has no icon or sound, and uses the Application.Title value as the title.
