Yes, a property is the easiest way to share data between an immediate CA and the wix code.
It's also possible to temporarily alter the MSI database at install time if you want Windows Installer to alter the system state for you, such as adding or changing rows in the registry table. http://www.joyofsetup.com/2007/07/01/semi-custom-actions/ -----Original Message----- From: Natalie Carr [mailto:natalie.c...@measuresoft.com] Sent: 14 August 2012 09:49 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Wix C++ variables Is there a way to use certain variables in your wix code and your c++ dll functions? extern "C" UINT __stdcall RegProductName(MSIHANDLE hInstall) { HRESULT hr = S_OK; UINT er = ERROR_SUCCESS; char szLocalPath[MAX_PATH]; hr = WcaInitialize(hInstall, "RegProductName"); ExitOnFailure(hr, "Failed to initialize"); WcaLog(LOGMSG_STANDARD, "Initialized."); strcpy(szLocalPath, Orc_Get_Product_Name()); MsiSetProperty(hInstall, "ProductName", szLocalPath); LExit: er = SUCCEEDED(hr) ? ERROR_SUCCESS : ERROR_INSTALL_FAILURE; return WcaFinalize(er); } That is my code for my custom action, although im not sure if MsiSetProperty is what I need here, Is it possible what I am trying to achieve? If so does anyone have any examples on how I would set my variable so that I can access it in both WIX and the C++ Custom Action?
