我创建了一个程序,试图在网站上发布一个字符串,我收到此错误:
"服务器提交了协议违规.Section = ResponseStatusLine"
在这行代码之后:
gResponse = (HttpWebResponse)gRequest.GetResponse();
我该如何解决这个异常？
我发送了大量的POST数据(超过5000个字符),看来WP7 HttpWebRequest正在丢失这个过程中的一些内容......
数据是png转换为字节数组,然后转换为base64字符串.
如果我的数据长度为4941个字符,它将只发送1448个字符,请求的内容长度(通过wireshark验证)很好(Content-Length:4991).
我如何发送数据:
void SendPost()
{
// Create the web request object
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Method = "POST";
webRequest.ContentType = "application/x-www-form-urlencoded";
// Start the request
webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
}
void GetRequestStreamCallback(IAsyncResult asynchronousResult)
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
// End the stream request operation
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
// Create the post data
// Demo POST data (length = 3762)

// …我想在文本字段/文本框元素上使用Mircosoft UI自动化框架设置文本,这意味着AutomationElement来自ControlType.Edit或ControlType.Document.
目前我正在使用TextPattern以从其中一个获取文本AutomationElements:
TextPattern tp = (TextPattern)element.GetCurrentPattern(TextPattern.Pattern);
string text = tp.DocumentRange.GetText(-1).Trim();
但现在我想在中设置一个新文本AutomationElement.我在TextPattern课堂上找不到这方法.所以我试图使用ValuePattern但我不确定这是否是正确的方法:
ValuePattern value = element.GetCurrentPattern(ValuePattern.Pattern) as ValuePattern;
value.SetValue(insertText);
还有其他方法来设置文本值吗？
另一个问题是如何在Edit/ Document元素上更改文本时获取事件？我尝试使用TextChangedEvent但是在更改文本时我没有触发任何事件:
AutomationEventHandler ehTextChanged = new AutomationEventHandler(text_event);
Automation.AddAutomationEventHandler(TextPattern.TextChangedEvent, element, TreeScope.Element, ehTextChanged);
private void text_event(object sender, AutomationEventArgs e)
{
Console.WriteLine("Text changed");
}
环境 :
Intel Core 2 duo, 3 gig RAM
Ubuntu 9.10, Grails 1.3.5, Spring security plugin 1.1.2
JVM Parameters : -Xms512m -Xmx1024m -XX:MaxPermSize=512m
启动使用grails spring安全性插件的应用程序非常慢.我在这里发现了这个.解决方法建议设置匿名密钥,因为SecureRandom- "手动设置密钥使用" 似乎会减慢速度.
我把它设置Config.groovy得无济于事.
grails.plugins.springsecurity.anonymous.key="someuniquekey"
使用数字的地方someuniquekey.它仍然需要永远(约30秒)才能通过Configuring Spring Security...消息.
有任何想法吗？我是在错误的地方或错误的方式设置的吗？
谢谢,史蒂夫
是否有可能在Windows Phone 7中手动锁定手机方向？因为我正在使用加速度计来处理按钮的固定UI旋转.
我试过了:
在XAML中
SupportedOrientations="Landscape" Orientation="LandscapeLeft"
OrientationChanged="PhoneApplicationPage_OrientationChanged"
并在代码背后:
private void PhoneApplicationPage_OrientationChanged(object sender, OrientationChangedEventArgs e)
{
//Orientation locking
//Do nothing
}
但UI仍然在横向左侧和景观之间转换...
谢谢.
以下代码是否会引起ConcurrentModificationException副作用？
ArrayList<String> newList = new ArrayList<String>(list);
考虑到列表的大小非常大,并且当上面的代码被执行时,另一个线程同时修改列表.
我想在Android上移植libtiff.我使用的源版本是tiff 4.0.1.我在u1 android OS中构建这个源代码.运行mmm external/tiff 4.0.1 /我收到以下错误

在Xcode 4.3.2中,构建一个包含libavutil.affmpeg发行版的iPad应用程序,它构建并正确运行但是当我尝试运行单元测试(Cmd-U)时,我收到以下链接器错误:
ld:非法文本重定位到/myPath/libavutil.a(imgutils.o)中的cstring,来自/ myPath/libavutil.a(imgutils.o)中的_av_image_check_size,用于体系结构armv7 clang:错误:链接器命令失败,退出代码为1(使用-v看到调用)
这是在设备上(我们目前无法在模拟器中运行它,因为我们没有包含所有库的胖二进制文件).
为什么它会正常构建和运行,但在运行单元测试时却没有链接？
在这篇伟大的MSDN文章的帮助下,我的第一个想法是简单地检查进程是否使用提升的Administrator组,并使用AdjustTokenGroups()我将Administrator组设置为SE_GROUP_USE_FOR_DENY_ONLY.不幸的是,我们无法修改当前正在运行的进程的管理员组,因为它还具有该SE_GROUP_MANDATORY属性,这使得它无法进行更改.
MSDN文档有这样的说法:
该AdjustTokenGroups函数无法禁用具有结构中SE_GROUP_MANDATORY属性的组TOKEN_GROUPS.请CreateRestrictedToken改用.
所以,我完成了以下代码来实现这一目标;
bool _IsNewProcessLaunched()
{
HANDLE hToken = NULL;
bool hasRestarted = false;
if (!OpenProcessToken( GetCurrentProcess(),
TOKEN_ASSIGN_PRIMARY | TOKEN_QUERY | TOKEN_DUPLICATE | TOKEN_ADJUST_GROUPS,
&hToken ))
{
return hasRestarted;
}
PSECURITY_DESCRIPTOR pSID = NULL;
SID_IDENTIFIER_AUTHORITY SIDAuth = SECURITY_NT_AUTHORITY;
if(! AllocateAndInitializeSid( &SIDAuth, 2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&pSID) )
{
CloseHandle(hToken);
hToken = NULL;
return hasRestarted;
}
BOOL isAdmin = …winapi uac privilege-elevation access-token elevated-privileges
操作栏在徽标左侧显示一个空格.这个空间是为我认为的指示者保留的.
我想给这个空间定义一个20dp的距离.
我怎样才能做到这一点？
我可以将图标的填充设置为0,但这不会删除徽标和屏幕左侧之间的空间.
我试图通过使用自定义布局来解决它.但是有一点问题.每次活动启动时,首先会显示正常操作栏,然后显示自定义布局.
这是我显示自定义视图的方式:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom);
// Set up the action bar.
final ActionBar actionBar = getActionBar();
//set custom actionbar
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(R.layout.actionbar);
//Displays the custom design in the actionbar
actionBar.setDisplayUseLogoEnabled(false);
actionBar.setDisplayHomeAsUpEnabled(false);
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
}
这是在我的styles.xml中:
<!--Customize the actionbar-->
<item name="android:windowActionBarOverlay">false</item>
<item name="android:actionBarStyle">@style/MyActionBar</item>
<item name="android:actionButtonStyle">@style/MyActionButton</item>
