[WiX-users] How2: Few questions

[Urban J. Ing. <ur...@as...>]

First Hi2All,
    I have got few thinks I would like to solve and not sure about
solution, so...

1. Check if a file exists and then insert the value in Property. I
proposed this:
    <Property Id=3D"REGASMFILE"
Value=3D"c:\WINNT\Microsoft.NET\Framework\v1.1.4322\RegAsm.exe">
      <DirectorySearch Id=3D"SEARCH_DIR"
Path=3D"[%WindowsFolder]Microsoft.NET\" Depth=3D"999">
        <FileSearch Id=3D"SEARCH_FILE" Name=3D"RegAsm.exe" />
      </DirectorySearch>
    </Property>

- I am not sure if I can put default value
- Not sure when the value is filling in. I guess it is during
InstallInitialize.
- Not sure about duplicity search result (regasm for different
framework)

2. Need to execute exe file with arguments, ex.
"c:\WINNT\Microsoft.NET\Framework\v1.1.4322\RegAsm.exe"
SMTPCiselniky.dll /codebase /tlb
    I am not really sure what I should use: I suppose that I use a
Property, which is filled with value of executable file, in this case
regasm.exe included full path. Afterwards it could look like:
<CustomAction Return=3D"check" ExeCommand=3D"SMTPCiselniky.dll /codebase
/tlb" Property=3D"REGASMFILE" Id=3D"idCARunRegAsm"></CustomAction>

- Do I need set a directory, where SMTPCiselniky.dll is placed?
- Am I using right CA if I want firstly find and check regasm.exe
existence?
- Not sure about arguments, am I right placing them in ExeCommand
attribute?

3. Need to run smtpreg.vbs, should I use CA and run cscript.exe with
parameters or something different?
ex. : cscript "c:\Program Files\aaa\shared\smtpreg.vbs" /add 1 onarrival
SMTPCiselniky111 ASD.XML.WS.SMTPCiselniky111.OnArrivalCiselnikyPozadavek
"rcpt to=3Dc...@aa..."


Thanks for any help.. bye bye Xabatcha
