I found that to get data from CustomActionData property I need to set propetry which named same as a CA:
<Property Id="CABoxUpdate_deffered" Value="aa,bb,cc"/> <CustomAction Id="CABoxUpdate_deffered" BinaryKey="AdditionsDLL" DllEntry="BoxUpdate" Execute="deferred"/> But I steel cannot modify it's value due installation: <Property Id="CABoxUpdate_deffered" Value="aa,bb,cc"/> <CustomAction Id="CABoxUpdate_immediate" BinaryKey="AdditionsDLL" DllEntry="BoxUpdate" Execute="immediate"/> <CustomAction Id="CABoxUpdate_deffered" BinaryKey="AdditionsDLL" DllEntry="BoxUpdate" Execute="deferred"/> <InstallExecuteSequence> <Custom Action="CABoxUpdate_immediate" After="InstallFiles"></Custom> <Custom Action="CABoxUpdate_deffered" After="InstallFiles"></Custom> </InstallExecuteSequence> extern "C" UINT __stdcall BoxUpdate(MSIHANDLE hInstall) { TCHAR szPath[500], szStr[1000], szBoxAddresses[1000], szBox[NI_MAXHOST]; DWORD dwLen; if (MsiGetMode(hInstall, MSIRUNMODE_SCHEDULED) == FALSE) { MsiSetProperty(hInstall, L"CABoxUpdate_deffered", L"cc,bb,aa"); } else { UINT iResult = MsiGetProperty(hInstall, L"CustomActionData", szPath, &(dwLen = 500)); } szPath in deffered execution is "aa,bb,cc", but not "cc,bb,aa" At log I see, that install set's new property value: MSI (s) (EC:30) [16:59:43:312]: Executing op: CustomActionSchedule(Action=CABoxUpdate_deffered,ActionType=1025,Source=BinaryData,Target=BoxUpdate,CustomActionData="aa,bb,cc") -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Executing-CA-after-InstallFiles-tp6076921p6088549.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ What You Don't Know About Data Connectivity CAN Hurt You This paper provides an overview of data connectivity, details its effect on application quality, and explores various alternative solutions. http://p.sf.net/sfu/progress-d2d _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
