function OnShowUI() BOOL bMaintenanceMode, bUpdateMode; string szIgnore, szTitle; begin
// Enable dialog caching Enable( DIALOGCACHE );
// Determine what events to show. bUpdateMode = FALSE; bMaintenanceMode = FALSE;
// Remove this to disabled update mode. if( UPDATEMODE ) then bUpdateMode = TRUE; endif;
// Remove this to disable maintenance mode. if ( MAINTENANCE ) then bMaintenanceMode = TRUE; endif;
// Show appropriate UI
// TODO: Enable if you want to enable background etc. //if ( LoadStringFromStringTable( "TITLE_MAIN", szTitle ) < ISERR_SUCCESS ) then // Load the title string. // szTitle = IFX_SETUP_TITLE; //endif; //SetTitle( szTitle, 24, WHITE ); //Enable( FULLWINDOWMODE ); //Enable( BACKGROUND ); //SetColor( BACKGROUND, RGB( 0, 128, 128 ) );
/* if( bUpdateMode ) then OnUpdateUIBefore(); else if ( bMaintenanceMode ) then OnMaintUIBefore(); else OnFirstUIBefore(); endif; endif; */ OnFirstUIBefore();
// Move Data OnMoveData();
/*if( bUpdateMode ) then OnUpdateUIAfter(); else if ( bMaintenanceMode ) then OnMaintUIAfter(); else OnFirstUIAfter(); endif; endif; */ OnFirstUIAfter(); // Disable dialog caching Disable(DIALOGCACHE);

Note that OnFirstUIBefore is only intended to be called on a first time install. Calling it in maintenance mode may not behave as expected.
thanks . it does not occur when i remove the modified. the original codes of OnShowUI() function that the event-wizard created ,it runs right .
i want force install the project built by IS2009 to another directory , when the project determine an older version of the project .and i don't want uninstall the older version project .
You may want to try using the multi-instance support that is provided with InstallScript projects. This would provide the option to install a new instance of the product (thereby allowing the product to be installed in different locations on one machine) or run an existing instance in maintenance mode.
Multi-instance support can be enabled from the Project->Settings | Maintenance tab in InstallScript projects.
i have any questions : 1: the every version could run depended ??? 2: the shortcuts of those projects which on the program group of star menu can have multiple ? and they are one-to-onetransformation??
Each instance (from the InstallScript engine's view) are independent of each other. However, with any multi-instance style setup, the installation needs to be authored carefully to ensure one instance does not interfere with the others (for example, if the installation contains COM objects that must be registered, a COM object can only be registered once on any machine, which then creates an issue with multiple instance setups). You may want to create a separate shortcut folder (assuming shortcuts are on the start menu) for each instance.
There aren't really any options to force new instances to be installed, the option is given to the user running the installation. You may try using the /ig command line parameter when launching setup.exe to specify the instance you would like to use (this parameter requires specifying a valid guid for the instance).
There aren't any options available to install multiple instances of a product without enabling multiple instance support. You could set the project to "no maintenance or uninstall" but then it will be impossible to uninstall the product.
