I found a solution, the custom action DLL isn't writing to console unless I
call AttachConsole as like below
cpid = GetCurrentProcessId();
hWnd = FindWindowEx(NULL, NULL, _T("ConsoleWindowClass"), NULL);
//this need not be the same console where the process is running at
//need to fetch parent process id & check if they are same
GetWindowThreadProcessId(hWnd, & ppid);
cppid = GetParentPID(cpid); //user defined function to get the parent id
if(cppid == ppid) //then this is the same console what we are looking for
{
AttachConsole(cppid);
WriteConsole(szBuffer);
FreeConsole();
}
else
{
//continue with FindWindow till the right parent is identified
}
Also smoke isn't calling CA directly instead its validation engine invokes
these CA through msiexec process, so GetParentPID has to get its 2 parents
for to cmd.exe PID
Now I need to redirect validation errors that are displayed in console to
log file I know this could be done by using something like
smoke.exe - cub myCub.cub myMSI.msi > smoke.log
but every time I run the smoke the log file gets overwritten, is there a way
that I can append to the existing log file.
If I do create my own logging in the CA then this log contains only those
logs generated by my CA which in case the other validations of ICEs (1-100)
done by darice.cub will not be listed into my log file, so this is not the
efficient solution. It would be much efficient if the log file generated by
> switch in the command line could get appended every time the program is
executed

customaction
I already tried below solution but is not writing to console, I think
MsiProcessMessage works only if the custom action is run through msiexec or
if the CA is immediate mode, but where as I am running these CA through
smoke utility & for the CA to be made immediate I will have to create the CA
from using installer project work space.
In some of samples I have seen it uses OutputDebugString for writing it to
the console

You need to use MsiProcessMessage with the INSTALLMESSAGE_USER type. See
http://msdn.microsoft.com/library/aa369205.aspx for details.

Subject: [WiX-users] writing to console from smoke.exe using custom action
Hi,
I wrote a custom action dll in C++ & added to .cub file that I am using in
-cub switch in smoke.exe, I was not successful in writing to console like
the ICE(s) in darice.cub does it but I am able to display the log info in
MessageBox.
Thanks,
Nag
