Hi ,
In Installscript , while calling LaunchAppAndWait API, it returns successfull . i.e returns Zero. But while the return code from LAAW_PARAMETERS.nLaunchResult = "259". What is the reason for such conflict ?

Here the code follows:

LaunchAppAndWait( "exampl.exe", "", LAAW_OPTION_WAIT | LAAW_OPTION_HIDDEN);-----> returns 0 --- successful.

LAAW_PARAMETERS.nLaunchResult ----> returns 259.

Please reply if anyone knows. Thanks in advance

LaunchAppAndWait returning 0 means the application was successfully launched.

 

LAAW_PARAMETERS.nLaunchResult tells you the exit code that the launched application returned to the calling process (InstallShield). You need to check the documentation for the launched application to see what 259 means.

I have the same result "259", but my launched application is returning a path. So I think the problem ist the conversion from number to string via NumToString function:

nRet1 = LaunchAppAndWait("my.exe", "my param", LAAW_OPTION_SHOW_HOURGLASS);

if (nRet1 = ISERR_SUCCESS) then

NumToStr(sRet1, LAAW_PARAMETERS.nLaunchResult);

SuiteLogInfo ("return: %s", sRet1);

endif;

Anyone any ideas how I get the returned path? Or is it not possible at all to get a returned string with LaunchAppAndWait?

Exit Code 259: STILL_ACTIVE

 

I also had this once -- if I remember correctly the meaning was that the process was still running and I needed to wait for it to end.
