It's OT but wrt your WTL prob Aris, might you have missed some other dependency? (Depends.exe v. handy here).

Re: [WiX-users] Easy WiX way for a custom action to call multiple utility DLLs?
I'm admittedly hardcore about this but IMHO custom actions should be native code DLLs that have as few dependencies as physically possible (certainly should have no dependency on WTL). Statically linking the CRT then use as few DLLs from the system provides the highest probability that the code will work in the most number of environments. Personally, development time takes a back seat to correctness and robustness. Yes, I realize that other people face different time pressures. I just view custom actions as an extension to the Windows Installer and thus need to be extremely robust with the minimal prerequisites.

Static linking definitely seems like the right thing to do. This is what I have done with VC 2003 and earlier for previous installs. However I have noticed that some programs, such as a WTL 8.0 Win EXE (I avoid MFC) I wrote, did not work on a lot of XP Pro SP2 machines when I statically linked it. The dialogs would not load their resource templates and were completely blank. However, when I linked the CRT as a DLL, it worked; I don't know why. Also, if the CLR is used in a CA, i.e. a managed function exported as an unmanaged functions as opposed to the installutil type components, I believe that you can't use static linking to the CRT and that the CRT has to be linked in as a DLL. Mayber CA's using managed code is not such a good idea. I know some people are against managed code in CA's, but if you know that .NET 2.0 is on the box, they can save a lot of time. - This SF.net email is sponsored by: Splunk Inc.

Re: [WiX-users] Easy WiX way for a custom action to call multiple utility DLLs?
Try embedding the other DLL as a custom resource using the .rc file. Extract the DLL first thing when the CA is called. Use delayload linker option or LoadLibrary to call the function in the extracted DLL. I've done this before. A question, how do VC 2005 CA's requiring the C++ CRT Dll work on Vista? Any CRT using C++/CLI require a DLL link to the CRT.

[WiX-users] Easy WiX way for a custom action to call multiple utility DLLs?
If my CA in MyCA.dll needs to call a fn in MyUtils.dll then I'm currently expecting to have to write a separate pair of CAs that pull MyUtils.dll out of the Binary table and then delete it at end-of-setup. InstallShield provides just such a handy pair of Custom Actions (ISSETUPFILESEXTRACT & co.), and I was wondering if there's any WiX equivalent? tia, Karim -- View this message in context: http://www.nabble.com/Easy-WiX-way-for-a-custom-action-to-call-multiple-utility-DLLs--tf4683485.html#a13382997 Sent from the wix-users mailing list archive at Nabble.com. - This SF.net email is sponsored by: Splunk Inc.
