Hide a preference screen in android -

-

I have a priority xml ..

Load preferences from an XML resource first 

  AddLocationFram Resource (R. XML Preferences);   
 And setting some default values ​​for it ... After setting the default value, to hide one of my preference screen (not to delete)  
 My preference is XML  
  & lt; Priority xmlns: android = "http://schemas.android.com/apk/res/android" & gt; & Lt; Priority Android: Title = "Account Settings" Android: key = "customPref" /> & Lt; PreferenceScreen Android: title = "@ string / account_1" Android: key = "account" & gt; & Lt; EditTextPreference Android: key = "username" android: title = "@ string / settings_username" android: singleLine = "true" /> Android: password = "true" android: singleLine = "true" /> & Lt; / PreferenceScreen & gt; & Lt; PreferenceScreen Android: Title = "@ String / Account 2" Android: key = "account1" & gt; & Lt; EditTextPreference Android: key = "username1" android: title = "@ string / settings_username" android: singleLine = "true" /> Android: edit = & lt; / PreferenceScreen & gt; & Lt; / PreferenceScreen & gt;   
 Let me hide the  priority screen   
  title = "@ string / account_2   You can duplicate your XML, then delete the second part as such:  
 
  & lt; PreferenceScreen xmlns: Android = "http://schemas.android.com/apk/res/android"> Priority Android: Title = "Account Settings" Android: key = "customPref" / & Gt; & lt; Priority Screen Android: Title = "@ String / Account_1" Android: Key = "Account" & gt; & lt; EditTextPreferenc E Android: key = "user name" Android: title = "@ string / settings_username" Android: singleLine = "true" /> & lt; Android: Android: single = "true" /> gt; & lt; / Priority screen & gt; & lt; / Preferences screen & gt;     / Pre> 
 Then you check your preference to see if it first  
 If yes, then you load the XML above, otherwise the first is not.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

javascript - What is an alternative to using getElementByClass for hiding multiple elements? -

-
I have a page with some links that I would like to be able to toggle with two buttons. It works with a link using getElementById, but I need to toggle some of those groups. I started with it, but it failed to work. I've heard that GetElementByClass has worked with everything but IE, but I'm using Opera 11.5 and it still does not work. I've searched a bit, but I'm new to some JavaScript and most of the explanation is not understood. Does anyone help me with a simple option, or can I help me fix the problem I've made? This is a test page I was using. & lt; Head & gt; & Lt; Script type = "text / javascript" & gt; Function hideNames () {document.getElementByClass ("WebName"). Style.display = "none"; } Function ShowName () {document.getElementByClass ("WebName"). Style.display = "inline"; } & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; P class = "web...

c# - GetType() == type perfomance question -

-
I am making an XNA game and I am calling the following updates 2 to 20 times the code. I tried googling and it seems that it is half slow, so I thought I was asking what kind of fast way to compare the type? code: Public modifier for this [type type] {for (int i = 0; i & lt; this.Qount; i ++) {if ( It [I.] Type GETType () ==) {Please return this [ii]; }} New NotImplementedException Throw ("Fix It"); } Set {for (int i = 0; i & lt; this.Qount; i ++) {if (this [i]. Type GetType () ==) {this [i] = value; }} If (System. Diagnostics.Debugor.ISAcredited) system. Diagnostics. Debugger. Break (); }} This code is in the modifier collection section which comes from a list. The modifier is a part of the particle engine. In addition, my game is not in a situation where I can actually do this test, so I can not test it, but should it work right? I read something about runtime typhanies, which is fast, should I use it? Thanks a lot! Edit: What I'm aiming to do ...
