EzBatchReplace Example

InstallShield 2016 » InstallScript Language Reference

Note • To call this function in a Basic MSI setup, you must first create a custom action for the entry-point function, execute the custom action in a sequence or as the result of a dialog's control event, and then build the release.

/*--------------------------------------------------------------*\

*

* InstallShield Example Script

*

* Demonstrates the EzBatchReplace function.

*

* EzBatchReplace is called to replace lines in a batch file.

*

* This script replaces three lines in the specified batch file.

* First, it replaces the SET COMSPEC command.  Then it replaces

* the PATH statement.  Finally, it replaces the command line

* that references SMARTDRV.EXE.

*

* Note: Before running this script, create a batch file

*       named ISExampl.bat and store it in the root of

*       drive C.  For best effect, that file should include

*       the following lines:

*

*       SET COMSPEC=C:\COMMAND.COM

*       PATH C:\

*       SMARTDRV.EXE

*

\*--------------------------------------------------------------*/

#define EXAMPLE_BAT "C:\\ISExampl.bat"

// Include Ifx.h for built-in InstallScript function prototypes.

#include "Ifx.h"

export prototype ExFn_EzBatchReplace(HWND);

function ExFn_EzBatchReplace(hMSI)

begin

    // Set the default batch file.

    BatchSetFileName (EXAMPLE_BAT);

    // Replace the SET COMSPEC statement.

    if (EzBatchReplace ("SET COMSPEC=C:\\DOS\\COMMAND.COM") < 0) then

        MessageBox ("First call to EzBatchReplace failed.", SEVERE);

    else

        MessageBox ("First call to EzBatchReplace succeeded.", INFORMATION);

    endif;

    // Replace the PATH command.

    if (EzBatchReplace ("PATH C:\\DOS;C:\\MYAPP") < 0) then

        MessageBox ("Second call to EzBatchReplace failed.", SEVERE);

    else

        MessageBox ("Second call to EzBatchReplace succeeded.", INFORMATION);

    endif;

    // Replace the SMARTDRIVE statement.

    if (EzBatchReplace ("SMARTDRV.EXE /P 1024 /C 512") < 0) then

        MessageBox ("Third call to EzBatchReplace failed.", SEVERE);

    else

        MessageBox ("Third call to EzBatchReplace succeeded.", INFORMATION);

    endif;

end;
