使用 MSIEXEC.EXE 安裝 msi 時，指定 All Users

MSIEXEC.EXE /I MyPackage.msi
When no value is specified the application is installed "Per User" placing shortcuts in the current user profile.

MSIEXEC.EXE /I MyPackage.msi ALLUSERS=1
This installs shortcuts to the "All Users" profile, only administrators will be able to install the shortcuts in this way.

MSIEXEC.EXE /I MyPackage.msi ALLUSERS=2
For users, this will install the shortcut in the current user profile, for administrators, this will still install the profile for "All Users". As an administrator, if you wish to install the shortcuts in your own local profile, do not specify a value for the ALLUSERS property.

RegistryKey.SetValue 遇到 UnauthorizedAccessException

string user = Environment.UserDomainName + "\\" + Environment.UserName
        RegistryAccessRule rule = new RegistryAccessRule(user,
        RegistryRights.FullControl,
        AccessControlType.Allow);

javax.xml.ws.WebServiceException: 無法建立 JAXBContext

使用 web service 時如果有 throw exception 的話，會遇到 "javax.xml.ws.WebServiceException: 無法建立 JAXBContext" 的錯誤

java.security.PrivilegedActionException: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions java.lang.StackTraceElement does not have a no-arg default constructor.

把 throw exception 拿掉，改用 try..catch 就可以了

javascript 執行減法運算

在 javascript 執行 float 相減時，可能會發生 9.700000000000001 的情形
為防止這個情形發生，必需加上 .toFixed()

例如:
var i = 9.8;
i = (i - 0.1).toFixed(1); // i => 9.7

解決 sencha touch 2.2.x 在 Chrome 29.x 執行時，textfield 無法顯示的問題

參考來源：http://druckit.wordpress.com/2013/08/22/sencha-touch-2-x-and-google-chrome-29/

There’s a bug in Google Chrome 29 that prevents Sencha Touch 2.2.x apps from displaying properly. While this shouldn’t affect mobile browsers (yet), it will affect you if you use Chrome to debug your apps.

You can patch your Sencha Touch 2.2.x apps by modifying the /touch2/resources/themes/stylesheets/sencha-touch/base/mixins/_Class.scss file, replacing the st-box mixin with the following code:

1 2 3 4 5 6 7 8 9 10 11

@mixin st-box($important: no) {     @if $important == important {         display: flex !important;         display: -webkit-box !important;         display: -ms-flexbox !important;     } @else {         display: flex;         display: -webkit-box;         display: -ms-flexbox;     } }

修改後，必需重新 compile

切換到 /Project/resources/sass 目錄下，執行 compass watch .

response.setHeader 下載檔名遇到中文字的解決方法

response.setContentType("application/x-x509-ca-cert");
response.setContentLength(byteCert.length);
// caname 是中文字
// Safari & Firefox & Chrome
String fileName = new String(caname.getBytes(), "ISO8859-1");

String agent = request.getHeader("USER-AGENT");
if (null != agent && -1 != agent.indexOf("MSIE")) {
    // IE
    fileName = URLEncoder.encode(fileName, "UTF8").replaceAll("\\+", "%20");
}

response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + ".cer\"");

從 web service 取得 ServletContext 物件

// ServletContextListener Class


public void contextInitialized(ServletContextEvent sce) {
  try {
    sce.getServletContext().setAttribute("myBook", "Learning java");
  } catch (Exception ex) {
  }
}


// WebService


@Resource
WebServiceContext wsContext;

@WebMethod(operationName = "test1")
public String test1() {
  ServletContext servletContext = (ServletContext) wsContext.getMessageContext().get(MessageContext.SERVLET_CONTEXT);
  String myBook = (String) servletContext.getAttribute("myBook");
}

Get viewport size (Nice)

var w = window,
d = document,
e = d.documentElement,
g = d.getElementsByTagName('body')[0],
x = w.innerWidth || e.clientWidth || g.clientWidth,
y = w.innerHeight|| e.clientHeight|| g.clientHeight;
alert(x);
alert(y);

Post data to a new window with full screen

Javascript Example:


function postDataToNewWindow() {
var myform = document.createElement("form");
myform.setAttribute("method", "post");
myform.setAttribute("action", "verifyCredential.asp");
myform.setAttribute("target", "_custom");

var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", "credential");
hiddenField.setAttribute("id", "credential");
hiddenField.setAttribute("value", "2.0");

myform.appendChild(hiddenField);
document.body.appendChild(myform);
window.open("", "_custom", "fullscreen=yes");
myform.submit();
}
