  • How can a wix custom action dll call be made to use the debug runtime via a merge module?

    - by Benj
    I'm trying to create a debug build with a corresponding debug installer for our product. I'm new to Wix so please forgive any naivety contained herein. The debug Dlls in my project are dependent on both the VS2008 and the VS2008SP1 debug runtimes. I've created a merge module feature in wix to bundle those runtimes with my installer. <Include xmlns="http://schemas.microsoft.com/wix/2006/wi"> <!-- Include our 'variables' file --> <!--<?include variables.wxi ?>--> <!--<Fragment>--> <DirectoryRef Id="TARGETDIR"> <!-- Always install the 32 bit ATL/CRT libraries, but only install the 64 bit ones on a 64 bit build --> <Merge Id="AtlFiles_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_ATL_x86.msm" DiskId="1" Language="1033"/> <Merge Id="AtlPolicy_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_ATL_x86.msm" DiskId="1" Language="1033"/> <Merge Id="CrtFiles_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_DebugCRT_x86.msm" DiskId="1" Language="1033"/> <Merge Id="CrtPolicy_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_DebugCRT_x86.msm" DiskId="1" Language="1033"/> <Merge Id="MfcFiles_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_DebugMFC_x86.msm" DiskId="1" Language="1033"/> <Merge Id="MfcPolicy_x86" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_DebugMFC_x86.msm" DiskId="1" Language="1033"/> <!-- If this is a 64 bit build, install the relevant modules --> <?if $(env.Platform) = "x64" ?> <Merge Id="AtlFiles_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_ATL_x86_x64.msm" DiskId="1" Language="1033"/> <Merge Id="AtlPolicy_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_ATL_x86_x64.msm" DiskId="1" Language="1033"/> <Merge Id="CrtFiles_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_DebugCRT_x86_x64.msm" DiskId="1" Language="1033"/> <Merge Id="CrtPolicy_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_DebugCRT_x86_x64.msm" DiskId="1" Language="1033"/> <Merge Id="MfcFiles_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\Microsoft_VC90_DebugMFC_x86_x64.msm" DiskId="1" Language="1033"/> <Merge Id="MfcPolicy_x64" SourceFile="$(env.CommonProgramFiles)\Merge Modules\policy_9_0_Microsoft_VC90_DebugMFC_x86_x64.msm" DiskId="1" Language="1033"/> <?endif?> </DirectoryRef> <Feature Id="MS2008_SP1_DbgRuntime" Title="VC2008 Debug Runtimes" AllowAdvertise="no" Display="hidden" Level="1"> <!-- 32 bit libraries --> <MergeRef Id="AtlFiles_x86"/> <MergeRef Id="AtlPolicy_x86"/> <MergeRef Id="CrtFiles_x86"/> <MergeRef Id="CrtPolicy_x86"/> <MergeRef Id="MfcFiles_x86"/> <MergeRef Id="MfcPolicy_x86"/> <!-- 64 bit libraries --> <?if $(env.Platform) = "x64" ?> <MergeRef Id="AtlFiles_x64"/> <MergeRef Id="AtlPolicy_x64"/> <MergeRef Id="CrtFiles_x64"/> <MergeRef Id="CrtPolicy_x64"/> <MergeRef Id="MfcFiles_x64"/> <MergeRef Id="MfcPolicy_x64"/> <?endif?> </Feature> <!--</Fragment>--> </Include> If I'm doing a debug build of the installer, I include that feature like so: <!-- The 'Feature' that contains the debug CRT/ATL libraries --> <?if $(var.Configuration) = "Debug"?> <?include ..\includes\MS2008_SP1_DbgRuntime.wxi?> <?endif?> The only problem is that my installer also includes a custom action which is also dependent on the debug runtime: <!-- Private key installer --> <Binary Id="InstallPrivateKey" SourceFile="..\InstallPrivateKey\win32\$(var.Configuration)\InstallPrivateKey.dll"></Binary> <CustomAction Id='InstallKey' BinaryKey='InstallPrivateKey' DllEntry='InstallPrivateKey'/> So how can I package the debug run time in such a way that the custom action also has access to it?

  • How to Change the Default Application for Android Tasks

    - by Jason Fitzpatrick
    When it comes time to switch from using one application to another on your Android device it isn’t immediately clear how to do so. Follow along as we walk you through swapping the default application for any Android task. Initially changing the default application in Android is a snap. After you install the new application (new web browser, new messaging tool, new whatever) Android prompts you to pick which application (the new or the old) you wish to use for that task the first time you attempt to open a web page, check your text message, or otherwise trigger the event. Easy! What about when it comes time to uninstall the app or just change back to your old app? There’s no helpful pop-up dialog box for that. Read on as we show you how to swap out any default application for any other with a minimum of fuss.

  • SQL SERVER – A Cool Trick – Restoring the Default SQL Server Management Studio – SSMS

    - by pinaldave
    “I do not know where my windows went!” “I just closed my object explorer and now I cannot find it.” “How do I get my original windows layout back in SQL Server Management Studio?” “How do I get the window which was there in left side back again?” Since last 2-3 years, every single day I receive more than 5 emails on SSMS and its layout. For the beginners it is very common to get confused when they attempt to change SQL Server Management Studio’s windows layout. They often change the layout and are not able to get the original layout back. Often people do not change the layout whole of their life, leading to uncomfortable feeling when they go to another’s computer where the windows are differently placed. Today’s blog post is dedicated all the beginners in SQL Server. It is extremely simple to reset the SSMS layout to default layout. The default layout involves 2 major things 1) Object Explorer on left side 2) Query Windows on right side (80% screen estate). Personally I am so used to this as well that if there is any other changes in the same, I do not enjoy working on the environment. Well, the solution to rest the SSMS layout is very simple. One can do it in split seconds.  To restore the default configuration, on the Window menu, click Reset Window Layout. Have you ever used this feature? Do you feel uncomfortable when SSMS layout is not in default state? How do you address this situation?

  • Making "default saved" work with GRUB2...?

    - by baltusaj
    I just installed Moblin Operating System. It's using GRUB2. On my Ubuntu 8.04 GRUB 0.97 was being used in which i was using the default saved option comfortably. I found that with GRUB2 i should not edit /boot/grub/menu.lst directly but I did :) because my Moblin does not contain any /etc/default/grub where they say I should do the modification I want. So what I did is as following which did not work: default=saved timeout=1 #splashimage=(hd0,0)/boot/grub/splash.xpm.gz #hiddenmenu #silent title Moblin (2.6.31.5-10.1.moblin2-netbook) root (hd0,0) kernel /boot/vmlinuz-2.6.31.5-10.1.moblin2-netbook ro root=/dev/sda1 vga=current savedefault=1 title Pathetic Windows rootnoverify (hd0,1) chainloader +1 savedefault=0 By doing so I should have automatically switch between Moblin and Window at each boot but it's not working. Almost all the troubleshooters on internet are saying that I should enable the DEFAULT=save option in /etc/default/grub but I am unable to find this file. Any idea what else should I do? Thanks a lot Update: I used the equal to sign because by default my menu.lst had an entry as default=0. However, default 0, is also working fine. Moreover the menu.lst, i have is actually a symbolic link to ./grub.conf. I have also noticed that grub-intall and grub-set-default commands are not working.

    I wanted to create an option in the context menu to set the clicked picture to current desktop background (just like in Windows). I read the the nautilus action help but I couldn't figure it out.

  • How to run a custom action after install which can run in quiet or a UI after Install (WIX)

    - by Jamie
    Hi, I basically want to able to run an command line tool that already exists on the desired machine against the directory the files were run to. I.e The Installer does the following: Specify a location for the files to go into (INSTALLOCATION variable) Then after copying has finished run a tool which will zip the files and attach them to attach them to another application. <CustomAction Id="InstallTo" Return="check" Directory="INSTALLLOCATION" Execute="immediate" ExeCommand='"C:\MyTool\Here\Tool.exe" -ad [INSTALLLOCATION] Poop 1.0'/> <InstallExecuteSequence> <Custom Action="InstallTo" After="InstallFinalize">$InstallTo&gt;2</Custom> </InstallExecuteSequence> At the moment I'm not sure anyuthing is being called, is there a way to basically have this two step install and report progress if the tool failed/doesn't exist etc. Thanks, Jamie

  • Weird Rails URL issue when rendering a new action

    - by Tony
    I am rendering a new action but somehow getting the "index" URL. To be more specific, my create action looks like this: class ListingsController < ApplicationController def create @listing = Listing.new(params[:listing]) @listing.user = @current_user if @listing.save redirect_to @listing else flash[:error] = "There were errors" render :action => "new" end end end When there are errors, I get the "new" action but my URL is the index URL - http://domain.com/listings Anyone know why this would happen? My routes file is fairly standard: map.connect 'listings/send_message', :controller => 'listings', :action => 'send_message' map.resources :listings map.root :controller => "listings" map.connect ':controller/:action/:id' map.connect ':controller/:action/:id.:format'

  • Windows 8.1 Will Start Encrypting Hard Drives By Default: Everything You Need to Know

    - by Chris Hoffman
    Windows 8.1 will automatically encrypt the storage on modern Windows PCs. This will help protect your files in case someone steals your laptop and tries to get at them, but it has important ramifications for data recovery. Previously, “BitLocker” was available on Professional and Enterprise editions of Windows, while “Device Encryption” was available on Windows RT and Windows Phone. Device encryption is included with all editions of Windows 8.1 — and it’s on by default. When Your Hard Drive Will Be Encrypted Windows 8.1 includes “Pervasive Device Encryption.” This works a bit differently from the standard BitLocker feature that has been included in Professional, Enterprise, and Ultimate editions of Windows for the past few versions. Before Windows 8.1 automatically enables Device Encryption, the following must be true: The Windows device “must support connected standby and meet the Windows Hardware Certification Kit (HCK) requirements for TPM and SecureBoot on ConnectedStandby systems.”  (Source) Older Windows PCs won’t support this feature, while new Windows 8.1 devices you pick up will have this feature enabled by default. When Windows 8.1 installs cleanly and the computer is prepared, device encryption is “initialized” on the system drive and other internal drives. Windows uses a clear key at this point, which is removed later when the recovery key is successfully backed up. The PC’s user must log in with a Microsoft account with administrator privileges or join the PC to a domain. If a Microsoft account is used, a recovery key will be backed up to Microsoft’s servers and encryption will be enabled. If a domain account is used, a recovery key will be backed up to Active Directory Domain Services and encryption will be enabled. If you have an older Windows computer that you’ve upgraded to Windows 8.1, it may not support Device Encryption. If you log in with a local user account, Device Encryption won’t be enabled. If you upgrade your Windows 8 device to Windows 8.1, you’ll need to enable device encryption, as it’s off by default when upgrading. Recovering An Encrypted Hard Drive Device encryption means that a thief can’t just pick up your laptop, insert a Linux live CD or Windows installer disc, and boot the alternate operating system to view your files without knowing your Windows password. It means that no one can just pull the hard drive from your device, connect the hard drive to another computer, and view the files. We’ve previously explained that your Windows password doesn’t actually secure your files. With Windows 8.1, average Windows users will finally be protected with encryption by default. However, there’s a problem — if you forget your password and are unable to log in, you’d also be unable to recover your files. This is likely why encryption is only enabled when a user logs in with a Microsoft account (or connects to a domain). Microsoft holds a recovery key, so you can gain access to your files by going through a recovery process. As long as you’re able to authenticate using your Microsoft account credentials — for example, by receiving an SMS message on the cell phone number connected to your Microsoft account — you’ll be able to recover your encrypted data. With Windows 8.1, it’s more important than ever to configure your Microsoft account’s security settings and recovery methods so you’ll be able to recover your files if you ever get locked out of your Microsoft account. Microsoft does hold the recovery key and would be capable of providing it to law enforcement if it was requested, which is certainly a legitimate concern in the age of PRISM. However, this encryption still provides protection from thieves picking up your hard drive and digging through your personal or business files. If you’re worried about a government or a determined thief who’s capable of gaining access to your Microsoft account, you’ll want to encrypt your hard drive with software that doesn’t upload a copy of your recovery key to the Internet, such as TrueCrypt. How to Disable Device Encryption There should be no real reason to disable device encryption. If nothing else, it’s a useful feature that will hopefully protect sensitive data in the real world where people — and even businesses — don’t enable encryption on their own. As encryption is only enabled on devices with the appropriate hardware and will be enabled by default, Microsoft has hopefully ensured that users won’t see noticeable slow-downs in performance. Encryption adds some overhead, but the overhead can hopefully be handled by dedicated hardware. If you’d like to enable a different encryption solution or just disable encryption entirely, you can control this yourself. To do so, open the PC settings app — swipe in from the right edge of the screen or press Windows Key + C, click the Settings icon, and select Change PC settings. Navigate to PC and devices -> PC info. At the bottom of the PC info pane, you’ll see a Device Encryption section. Select Turn Off if you want to disable device encryption, or select Turn On if you want to enable it — users upgrading from Windows 8 will have to enable it manually in this way. Note that Device Encryption can’t be disabled on Windows RT devices, such as Microsoft’s Surface RT and Surface 2. If you don’t see the Device Encryption section in this window, you’re likely using an older device that doesn’t meet the requirements and thus doesn’t support Device Encryption. For example, our Windows 8.1 virtual machine doesn’t offer Device Encryption configuration options. This is the new normal for Windows PCs, tablets, and devices in general. Where files on typical PCs were once ripe for easy access by thieves, Windows PCs are now encrypted by default and recovery keys are sent to Microsoft’s servers for safe keeping. This last part may be a bit creepy, but it’s easy to imagine average users forgetting their passwords — they’d be very upset if they lost all their files because they had to reset their passwords. It’s also an improvement over Windows PCs being completely unprotected by default.

  • Ignore Apache Default Server?

    - by Jakobud
    I run several vhosts on our Apache server. Whenever browse the server using either it's IP address or some other name that resolves to that address, but where a virtual host entry doesn't exist for that address I get the generic Apache test page: I want to change the server so I can specify a Virtual Host to see by default instead of the Apache Default Server page. I don't want to just modify the Default Server page either. I just need to be able to specify a Virtual Host to use instead. I added the following Virtual Host: <VirtualHost _default_:*> DocumentRoot /vhosts/default/public </VirtualHost> What I am reading is supposed to take priority over all other Virtual Hosts as the default. But this doesn't seem to take priority over the Apache Default Server/Host. What do I need to do here?

  • Windows Vista, Default Programs API, file format associations, and (un)installers - explosive mix!

    - by Alex T.
    My application is a rather well behaved Windows citizen, so when I ported it to Windows Vista/7 I replaced my custom file format association code with support for the Default Programs API. However I ran into a problem when trying to make uninstaller for my application - there seems to be no way to remove file format associations via Default Programs API. I tried to call IApplicationAssociationRegistration::ClearUserAssociations but it actually removes all associations, including the ones for other applications - completely restoring default state of the OS (which is of course unacceptable). I tried to call IApplicationAssociationRegistration::SetAppAsDefault to return file format associations to the previous "owner" - but it does not help, because my application handles many unique file formats which the OS does not support and there is no previous "owners". And Windows does not allow to pass empty strings to SetAppAsDefault... So what do I do? Any good solutions?

  • Does Apache need to be stopped to edit "/etc/apache2/sites-available/default"?

    - by webworm
    I am attempting to edit the "default" file located at .. "/etc/apache2/sites-available/default" on my Ubuntu machine running Apache 2.2.8. I want to do this in order to enable the use of .htaccess files. I have downloaded the "default" file and edited it and now I am trying to upload it back to the server via SFTP. I keep getting permission denied errors. Could it be because Apache is running and making use of the file? I am an admin on the machine so I would expect to be able to overwrite the file. Thanks for any assistance.

  • Is it wise to rely on default features of a programming language?

    - by George Edison
    Should I frequently rely on default values? For example, in PHP, if you have the following: <?php $var .= "Value"; ?> This is perfectly fine - it works. But what if assignment like this to a previously unused variable is later eliminated from the language? (I'm not referring to just general assignment to an unused variable.) There are countless examples of where the default value of something has changed and so much existing code was then useless. On the other hand, without default values, there is a lot of code redundancy. What is the proper way of dealing with this?

  • Why doesn't the C++ default destructor destroy my objects?

    The C++ specification says the default destructor deletes all non-static members. Nevertheless, I can't manage to achieve that. I have this: class N { public: ~N() { std::cout << "Destroying object of type N"; } }; class M { public: M() { n = new N; } // ~M() { //this should happen by default // delete n; // } private: N* n; }; Then this should print the given message, but it doesn't: M* m = new M(); delete m; //this should invoke the default destructor
