Fix bug MSBUILD : error MSB3428: Could not load the Visual C++ component “VCBuild.exe” …
So here it is. I have tested these steps multiple times on (each time) newly created Windows 7 SP1 VMs with IE8.
Scenario: I have a brand new Windows system, what to do?
[Only if it is Windows 7 then and you don’t already] Download .NET Framework 4.5.1 and run the installer.
Download Build Tools 2015, run the build installer.
Download Visual C Build Tools 2015 Preview, run the installer, select Custom, click Next and check both SDKs (8 and 10), click Next and then Install.
Launch regedit Navigator to HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0. Add string key VCTargetsPath key, set VCTargetsPath=C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\v140
npm config set GYP_MSVS_VERSION 2015
Download and install latest node.js.
Download and install Python 2.7.x.
Open cmd and run npm config set msvs_version 2015 –global.
Hopefully it is a temporary registry fix and they will fix it before Build Tools get out of Technical Preview status. Out of 4 times it created that registry value once.
Start > Run > cmd (and press Ctrl+Shift+Enter to Run as Administrator):
For 64-bit Windows
:: copy paste this command and press enter reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\SxS\VS7 /v 14.0 /t REG_EXPAND_SZ /d ^%programfiles(x86)^%"\Microsoft Visual Studio 14.0\\"
For 32-bit Windows
:: copy paste this command and press enter reg add HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\SxS\VS7 /v 14.0 /t REG_EXPAND_SZ /d ^%programfiles^%"\Microsoft Visual Studio 14.0\\"
Now install the package like npm install selenium-webdriver and it should work!
My installation is not brand new, I had some related stuff installed and now I am getting MSB4019 or MSB8020.
This means somehow you have incorrect version of msbuild in PATH. To fix that, put C:\Program Files (x86)\MSBuild\14.0\Bin; at the beginning of PATH under System Environment Variables. To do it quickly (without making permanent change), run SET PATH=%ProgramFiles(x86)%\MSBuild\14.0\Bin;%PATH% in command prompt in case of 64-bit Windows or %ProgramFiles%\MSBuild\14.0\Bin; in case of 32-bit Windows. Then run your intended npm install command.
Finally, what to expect?
Expect every package which requires C/C++ code compilation at the time of installation to succeed on Windows, exactly as they compile at installation time on Unix-like operating systems, except those which are not supporting Windows at all (yet?) such as node-gd. For such packages, you can find their repository URL on package’s http://npmjs.org/ page and find the Windows support status in their issue tracker.

Cách xây dựng directive bằng Angular Js 1
Khi tạo 1 directive, đầu tiên ta phải suy nghĩ xem ta viết cái gì? Sau đó ta xem directive của ta hoạt động ra sao? Và cuối cùng là ta truyền vào cái gì để nó hoạt động?
Để mô tả luồng tư duy, mình thử viết 1 modal directive cơ bản nhất:
– Viết cái gì: Modal
– Hoạt động: Modal có tính năng click vào button thì hiện lên, click vào background thì tắt đi.
– Truyền vào: Biến bật/tắt và Content của modal.
Sau khi tư duy xong, ta có thể khái quát được mô hình như sau:
– name directive: modalWindow
– replace: true (dĩ nhiên)
– transclude: true (vì cần truyền content vào modal, sau này cứ khi nào directive cần truyền dynamic content vào thì transclude là true hết)
– biến bật/tắt: show (false là tắt, true là bật) Continue reading Cách xây dựng directive bằng Angular Js 1
Angular Js 1: Auth check when change state
Controller:
...
$stateProvider
.state('home.contact', {
url: '/contact',
resolve: {
currentAuth: function(AuthFactory) {
return AuthFactory.authPromise();
}
}
});
...
Service:
...
.factory('AuthFactory', function ($q, $timeout, $rootScope) {
var factoryObject = {
authPromise: function () { /* promise to check is login or not */
// Initialize a new promise
var deferred = $q.defer();
$timeout(function () {
if ($rootScope.isAuthenticated) {
deferred.resolve();
} else {
deferred.reject('AUTH_REQUIRED');
}
});
return deferred.promise;
}
};
return factoryObject;
})
...
Root Controller:
...
$rootScope.$on('$stateChangeError', function(event, toState, toParams, fromState, fromParams, error) {
if (error === 'AUTH_REQUIRED') {
$state.go('home.dash');
}
});
