A simple WIX installer that runs custom actions on install and uninstall.

Posted by | Win32, Windows | Tagged |

Below I provided the source code of WIX installer that shows the license, installation directory and runs custom actions on install and uninstall:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Product Id="*" Name="My Game" Language="1033" Version="1.0.0.0" Manufacturer="SharLines Corporation" UpgradeCode="...">
        ...    

        <Property Id="WIXUI_INSTALLDIR" Value="INSTALLFOLDER" ></Property>
        <WixVariable Id="WixUILicenseRtf" Overridable="yes" Value="License.rtf"/>
        <UIRef Id="WixUI_InstallDir"/>

        <InstallExecuteSequence>
            <Custom Action="InstallService" After="InstallFiles">(NOT Installed) AND (NOT REMOVE)</Custom>
            <Custom Action="UninstallService" After="InstallInitialize">(NOT UPGRADINGPRODUCTCODE) AND (REMOVE="ALL")</Custom>
        </InstallExecuteSequence>
        <CustomAction Id="InstallService" Return="check" Impersonate="yes" Execute="deferred" Directory="INSTALLFOLDER" ExeCommand="[INSTALLFOLDER]$(var.MyService.TargetFileName) parameters..."/>
        <CustomAction Id="UninstallService" Return="check" Impersonate="yes" Execute="deferred" Directory="INSTALLFOLDER" ExeCommand="[INSTALLFOLDER]$(var.MyService.TargetFileName) parameters..."/>
    </Product>
    ...
</Wix>

MyService is project referenced by my wixproj in VS2015. If Impersonate=”yes” the command is run as the current user, if “no”, the command is run as “NT AUTHORITY\SYSTEM“. INSTALLFOLDER is defined as follows:

How NSIS plugins work

Posted by | Windows |

NSIS plugins are regular DLLs that export functions with typical def-files like this:

LIBRARY MY_NSIS_PLUGIN
EXPORTS
    AddUser      PRIVATE    
    CreateHive   PRIVATE
    ...

They should be put to “C:\Program Files\NSIS\Plugins\x86-ansi” directory for NSIS v3.x. From nsi-script their functions can be called like this:

Function MyFunc
  ...
  MY_NSIS_PLUGIN::CreateHive
  ...
FunctionEnd

How to debug classic ASP with VS2015 and IIS Express

Posted by | IIS, Windows | Tagged |

Change configuration/system.webServer/serverRuntime/asp section of $(SolutionDir).vs\config\applicationhost.config file to:

<asp scriptErrorSentToBrowser="true" enableParentPaths="true" bufferingOn="true" errorsToNTLog="true" appAllowClientDebug="true" appAllowDebugging="true">
    <cache diskTemplateCacheDirectory="%TEMP%\iisexpress\ASP Compiled Templates" />
    <session allowSessionState="true" />
    <limits />
</asp>

Open the website in a browser and then in VS2015 go to Debug->Attach To Process, change code type to Script and select iisexpress.exe. After that in browser navigate to a page you want to debug and Script Documents section will appear in Solution Explorer allowing you to set breakpoints on listed pages. Actually you do all the steps described in this post, except that you edit not the global IIS Express configuration, but local configuration located in VS2015 solution subdirectory .vs\config.

Squid 3.5.12 can be installed and tested on Ubuntu 16.04 with the following commands:

service squid start
sudo ufw allow 3128/tcp
wget -e use_proxy=yes -e http_proxy=http://localhost:3128 http://google.com

Installing Google Play Services on a Windows 10 with MS VS2015

Posted by | Android, QT, Windows |

If Android support is enabled in MS VS2015, it installs Android SDK without Google Play Services and I did not find an option in SDK Manager that installs them. When I started “C:\Program Files (x86)\Android\android-sdk\SDK Manager.exe” with admin privileges, it automatically offered to install some 9 packages:

Configuring Postfix with Yandex.ru relay in Ubuntu 16.04

Posted by | Ubuntu | Tagged |

Today I read that Postfix can be better than sendmail and found a great Russian article on how to configure Postfix to work with Yandex.ru relay (Yandex.ru is some kind of Russian Google). The only notice I would give is that in a Docker container I need also install rsyslog, otherwise /var/log/mail.log file is not created:

apt install rsyslog

After doing all the steps described in this Russian manual I was able to send email to Yandex.ru and GMail accounts, but GMail landed all the emails to its spam folder. My first idea was that it is because I did not configure ‘from address’ correctly, so I had the following in /var/log/mail.log, and also there was a message ‘Cannot assign requested address‘:

Oct 27 11:36:19 0675c97b78aa postfix/pickup[1210]: 8C7ECE5B72: uid=0 from=<root>
Oct 27 11:36:19 0675c97b78aa postfix/cleanup[10786]: 8C7ECE5B72: message-id=<20171027113619.8C7ECE5B72@0675c97b78aa.localdomain>
