I am calling a LaunchAppAndWait as shown below

chdir = TARGETDIR ^ "\\MySQL\\bin";
ChangeDirectory (chdir);
svpline = "/c " + TARGETDIR+"\\MySQL\\bin\\" + "mysql -u root -e \"source " + TARGETDIR + "\\MySQL\\bin\\DBInit.sql\"";
SprintfBox(WARNING, "running svpcmd cmd.exe %s",svpcmd);
if (LaunchAppAndWait("cmd.exe", svpline, LAAW_OPTION_WAIT|LAAW_OPTION_NO_CHANGEDIRECTORY|LAAW_OPTION_HIDDEN) < 0) then
SprintfBox(WARNING,"Failed to run dbinit.sql %s", svpcmd);
endif;


it does not work always. when i ran the setup.exe once it worked. I had to make more changes setup.rul and build it again. when trying again it does not work. seems LaunchAppAndWait does not wait ...

Youo may end up with duplicate backslashes in svpline. Why don't you use chdir instead of TARGETDIR+"\\MySQL\\bin\\" ? Also I don't think this will work properly if TARGETDIR contains blanks. You'll need to quote (LongPathToQuote) it or convert it to short path.

I've found that there's a limit to how long your command line parameter can be. How long? Not sure. I ended up creating a .bat file launcher for any launchappandwait function call. Perform a text replace on a batch file that will do the job of your LaunchAppAndWait function, then call LaunchAppAndWait on that batch file. Pain? Yes.
