如何查看通过ApplicationData.Current.LocalFolder.CreateFileAsync("...")操作创建的文件？
我记得Windows Phone Power Tools在Windows Phone中已经有8天了,但今天有什么方法可以做到这一点吗？
非常感谢你!
我正在使用TensorFlow实现分类模型
我面临的问题是，当我运行训练步骤时，我的体重和错误没有得到更新。结果，我的网络不断返回相同的结果。
我已经基于TensorFlow网站上的MNIST示例开发了我的模型。
import numpy as np
import tensorflow as tf
sess = tf.InteractiveSession()
#load dataset
dataset = np.loadtxt('char8k.txt', dtype='float', comments='#', delimiter=",")
Y = np.asmatrix( dataset[:,0] )
X = np.asmatrix( dataset[:,1:1201] )
m = 11527
labels = 26
# y is update to 11527x26
Yt = np.zeros((m,labels))
for i in range(0,m):
index = Y[0,i] - 1
Yt[i,index]= 1
Y = Yt
Y = np.asmatrix(Y)
#------------------------------------------------------------------------------
#graph settings
x = tf.placeholder(tf.float32, shape=[None, 1200])
y_ = tf.placeholder(tf.float32, shape=[None, 26])
Wtest …我创建了一个Facebook应用程序.我测试了它sandbox mode,它很好.
现在我想让其他人在手机上测试这个应用程序,所以我关闭sandbox mode,我发现iPhone-5用户无法登录,但它仍然可以在android手机中正常工作
这是错误日志 -
会话创建错误:错误Domain = com.facebook.sdk Code = 2"操作无法完成.(com.facebook.sdk error 2.)"UserInfo = 0x16561ad0
我检查了我的bundle id和app id,它不出差错
我试图设置我的选择框的默认选定项目，但是它没有按预期工作......
<ChoiceBox fx:id="d" value="- Select choice -">
<String fx:value="hellow"/>
</ChoiceBox>
我按照视频教程编写了这段代码.我得到一个java.lang.RuntimeException: setAudioSource failed错误导致Unable to start activity
我在安装了Cyanogenmod 13的第一代Moto G上进行调试.我的假设是我的自定义ROM与MediaRecorder存在冲突.任何想法将不胜感激!
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
我还应该提一下,我在AndroidManifest中拥有正确的权限
import android.media.MediaPlayer;
import android.media.MediaRecorder;
import android.os.Bundle;
import android.os.Environment;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
import java.io.IOException;
public class MainActivity extends AppCompatActivity {
MediaRecorder myAudioRecorder;
private String outputFile = null;
private Button start, stop, play;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
start = (Button) findViewById(R.id.button1);
stop = (Button) findViewById(R.id.button2);
play = (Button) findViewById(R.id.button3);
stop.setEnabled(false);
play.setEnabled(false);
outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myrec.3pg"; …我已经为Scrollview(8images)+工具栏完成了代码.当我尝试单击工具栏按钮项时,滚动视图不会按预期返回.下面是代码.
当我单击工具栏按钮,没有触发"IBAction clickprjinfo"的操作时,我已通过连接检查器中的Barbuttonitem确认已对此IBACTION执行了"SentAction".
在运行时,当我点击按住工具栏按钮+触摸scroolview屏幕+然后释放按钮,然后它触发IBACTION.
任何人都有助于通知我的错误或更好的方式来理解这一点.
-(void)viewDidLoad

[super viewDidLoad];

[scroller addSubview:images];
}
scroller.delegate=self;
scroller.contentSize=CGSizeMake(1024*8, 760);

要交付我们的网上商店，我们需要从当前日期开始以php计算5个工作日。
我们的工作日为星期一至星期五，还有几个休息日（假日），也不能包括在内。
我已经找到了此脚本，但这不包括假期。
<?php
$_POST['startdate'] = date("Y-m-d");
$_POST['numberofdays'] = 5;
$d = new DateTime( $_POST['startdate'] );
$t = $d->getTimestamp();
// loop for X days
for($i=0; $i<$_POST['numberofdays']; $i++){
// add 1 day to timestamp
$addDay = 86400;
// get what day it is next day
$nextDay = date('w', ($t+$addDay));
// if it's Saturday or Sunday get $i-1
if($nextDay == 0 || $nextDay == 6) {
$i--;
}
// modify timestamp, add 1 day
$t = $t+$addDay;
}
$d->setTimestamp($t);
echo $d->format('Y-m-d'). "\n"; …运行rails时出现以下错误.
