custom action - Dynamically changing CAs in WIX Install Sequence -


i'd find useful decide custom actions call @ points in installation depending on properties i've set in installer.

for example; if want use separate dlls interfacing different versions of sql (ssrs 2005/2008r2 specific).

assume actions discern ca should run (by finding out ssrs version installer being pointed at) executed "immediate" , ca's may or may not executed depend on result , "deferred"

how change deferred ca execute @ parts of install, dynamically, during install?.. possible?

((wix 2.0 preferred higher version answers acceptable))

in data driven custom actions modify machine state (which sounds writing) immediate custom action should read tables and/or properties in msi schedule appropriate deferred custom actions make changes machine.

to accomplish this, of custom actions defined (customaction elements in .wxs files) immediate custom actions scheduled (custom/@action elements in installexecutesequence). immediate custom actions about, make decisions, set customactiondata deferred custom action, call ::msidoaction() name of appropriate deferred custom action add deferred custom action installation script @ point. later, when windows installer executes installation script (the deferred part of install), deferred custom actions kick off data.

the wix toolset custom actions time if looking examples.

php - Why I am getting the Error "Commands out of sync; you can't run this command now" -

the documentation of error mentioned in title says if commands out of sync; can't run command now in client code, calling client functions in wrong order. this can happen, example, if using mysql_use_result() , try execute new query before have called mysql_free_result(). can happen if try execute 2 queries return data without calling mysql_use_result() or mysql_store_result() in between. from here: http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html but in first query not fetching data mysql database, inserting. , in second query getting data database. here code $connection = mysqli_connect("localhost","username","password","tbl_msgs"); if(mysqli_connect_errno($connection)) { die("failed connect mysql: " . mysqli_connect_error()); } $query = "insert users (total_comments, total_views) values ({$total_comments}, {$total_views});"; $query .= "insert msgs (no...

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
