A quick and simple guide on how to add a message box or popup into your Delphi.
Displays a modal dialog box that contains a system icon, a set of buttons, and a brief application-specific message, such as status or error information. The message box returns an integer value that indicates which button the user clicked. Syntax int WINAPI Message Box( _ In_opt_ HWND h Wnd, _ In_opt_ LPCTSTR lp Text, _ In_opt_ LPCTSTR lp Caption, _ In_ UINT u Type Parameters h Wnd [in, optional] Type: HWND A handle to the owner window of the message box to be created. If this parameter is NULL, the message box has no owner window. lp Text [in, optional] Type: LPCTSTR The message to be displayed. If the string consists of more than one line, you can separate the lines using a carriage return and/or linefeed character between each line. lp Caption [in, optional] Type: LPCTSTR The dialog box title. If this parameter is NULL, the default title is Error. u Type [in] Type: UINT The contents and behavior of the dialog box. This parameter can be a combination of flags from the following groups of flags. To indicate the buttons displayed in the message box, specify one of the following values. Value Meaning MB_ ABORTRETRYIGNORE 0x00000002 L The message box contains three push buttons: Abort, Retry, and Ignore. MB_ CANCELTRYCONTINUE 0x00000006 L The message box contains three push buttons: Cancel, Try Again, Continue. Use this message box type instead of MB_ ABORTRETRYIGNORE.

Delphi Basics messagedlg Function Displays a message, symbol, and selectable buttons Dialogs unit function messagedlg ( const Message : string; Dialog Type : TMsg Dlg Type; Buttons : TMsg Dlg Buttons; Help Context : Longint ) : Integer; Description The messagedlg function is used to display messages to the user. These messages may be informational, or warnings or whatever. There is complete freedom over the choice of buttons that the user may press to acknowledge the dialog. For example, the user may be shown an error message, and be allowed to abort, retry or cancel the erroneous process. The Dialog Type may have one of the following enumerated values: mt Warning Displays a exclamation symbol mt Error Displays a red ' X' mt Information Displays an 'i' in a bubble mt Confirmation Displays an question mark mt Custom Displays just the message The Buttons value may be one or more of the following enumerated values : mb Yes Displays a ' Yes' button mb No Displays a ' No' button mb OK Displays an ' OK' button mb Cancel Displays a ' Cancel' button mb Abort Displays an ' Abort' button mb Retry Displays a ' Retry' button mb Ignore Displays an ' Ignore' button mb All Displays an ' All' button mb No To All Displays a ' No to all' button mb Yes To All Displys a ' Yes to all' button mb Help Displays a ' Help' button You specify these values comma separated in square brackets, as in the second code example. Delphi provides a number of predefined button combinations: mb Yes No Cancel = [mb Yes,mb NO,mb Cancel] mb Yes All No All Cancel =[mb Yes,mb Yes To All, mb No,mb No To All,mb Cancel] mb OKCancel =[mb OK,mb Cancel] mb Abort Retry Cancel =[mb Abort,mb Retry,mb Cancel] mb Abort Ignore =[mb Abort,mb Ignore] Now Delphi seem to have made a design error when setting the return value from the dialog box. Instead of specifying the enumeration value of the button pressed, it uses a completely different set of enumeration names: mr Yes = 6.
Embarcadero has created a new non blocking Message Dlg function in Delphi XE7 and Appmethod Firemonkey to better support Android. The code does work on IOS, Windows, and OSX too. The new function takes an anonymous method as the last parameter and it gets executed when the user clicks one of the buttons. In Delphi XE5 and XE6 the function would block and would not execute code after the user clicked one of the buttons from the Message Dlg. Here is the example Message Dlg code from XE5 and XE6: case Message Dlg Do you want to press yes or no? System. UITypes. TMsg Dlg Type.mt Information, System. UITypes. TMsg Dlg Btn.mb Yes, System. UITypes. TMsg Dlg Btn.mb No],0)of Detect which button was pushed andshowadifferent message mr Yes:begin/ pressed yesend;mr No:begin/ pressed no Exit;end;end code here would run after the button clicks And here is the new code for Firemonkey XE7 with the anonymous method used: Message Dlg Do you want to press yes or no? System. UITypes. TMsg Dlg Type.mt Information, System. UITypes. TMsg Dlg Btn.mb Yes, System. UITypes. TMsg Dlg Btn.mb No],0,procedure(const AResult: TModal Result)begincase AResultof Detect which button was pushed andshowadifferent message mr Yes:begin/ pressed yesend;mr No:begin/ pressed noend;end;end/ code here would get executed right away Head over and check out the full documentation about the Message Dlg function on the Embarcadero docwiki.
