Meaning

0
Application-modal. The user must respond to the message box before continuing work in the application.

4096
System-modal. All applications are suspended until the user responds to the message box.

When adding numbers to create a final value for the argument type, use only one number from each group. If style is omitted, a default value of 0 is assumed.

Time-out

Optional numeric expression representing the number of seconds after which to close the dialog box.

Note

The time-out feature only works if the MESSAGEBOX dialog box is the active window for the duration of the time-out. If the user switches away from KiXtart and activates another application, the MESSAGEBOX dialog box is not closed.

Remarks

MESSAGEBOX displays a maximum of 1024 characters in application-modal dialog boxes. Longer messages are truncated after the 1024th character. Message strings longer than 255 characters with no intervening spaces are truncated after the 255th character. For system-modal dialog boxes, the number of characters you can display depends on screen resolution and number of lines in the message.

MESSAGEBOX breaks lines automatically at the right edge of the dialog box. If you want to set line breaks yourself, place a linefeed (ANSI character 10) before the first character of the text that is to begin each new line.

Returns

The value returned by MESSAGEBOX indicates which button was selected, as shown in the following table.

2
Cancel button selected.

3
Abort button selected.

4
Retry button selected.

5
Ignore button selected.

6
Yes button selected.

7
No button selected.

If the dialog box contains a Cancel button, pressing esc has the same effect as choosing Cancel.

Discussion There are two ways in which a silent uninstall can be performed. Using a Response File To run an uninstallation using a response file: 1. Prepare a response file for the uninstallation (.iss) by running Setup.exe with the /r argument: Setup.exe /r 2. Locate the Setup.iss file generated in the Windows folder and copy it to the desired location. 3. Type the following at the command line (items in Italics represent data that is specific to your product's uninstallation): IDriver.exe /M{Your Product GUID} /s /f1"<FULLY qualified path>\YourResponseFile.iss" Note: The /f1 parameter is necessary only if the Setup.iss file is located in a directory other than in the same location as Setup.exe. Simple Uninstallation If you do not want to follow the script logic and want to uninstall the product, you can use the following command line: IDriver.exe /M{Your Product GUID} /uninst The /uninst parameter causes a forced uninstallation without opening the script. It rolls back the system changes made during the installation, including those from the MSI package and any InstallShield scripting. Note: For both of these uninstallation options, the /M argument is case sensitive. Note: By default, the file "IDriver.exe" is located in the following path: <ProgramFiles>\Common Files\InstallShield\Driver\<Version>\Intel 32.
