Subject: [WiX-users] Reevaluating Dependent Properties
Hi All,
Is it possible to reevaluate dependent properties in WiX? I am using WiX
3.0.3907.0.
I have a property MYDIR that uses RegistrySearch to get an initial default
value.
<Property Id='MYDIR'> <RegistrySearch ... />
</Property>
The dependent property MYDATAFILE uses the value of MYDIR.
<Property Id='MYDATAFILE'> <DirectorySearch Id='SearchMyDir'
Path='[MYDIR]'> <FileSearch Id='FindMyDataFile'
Name='myData.txt' /> </DirectorySearch> </Property>
The above works fine if it finds the myData.txt file in the directory specified
in the registry search for MYDIR.
My problem occurs when the user changes the MYDIR value through the WiXUI
dialog boxes provided by my installer.
The MYDIR property is attached to another property so that I can use it in the
WiXUI dialog boxes.
<Property Id='WIXUI_MYDIR' Value='MYDIR'/>
In one of my WiXUI dialogs, I allow the user to select a different directory
for MYDIR
<Control Id='MyDir_Browse' Type='PushButton' ... > <Publish
Event='SpawnDialog' Value='BrowseDlg'>1</Publish> <Publish
Property='_BrowseProperty' Value='[WIXUI_MYDIR]'>1</Publish> </Control>
The above works and I see the value of MYDIR change to what the user selected.
However, I could not figure out a way to get MYDATAFILE to get reevaluated
after MYDIR changes. Can someone tell me how to force MYDATAFILE to get
reevaluated?
Thanks in advance for any replies,
Primo
