有谁知道如何使用VBA清除即时窗口？

虽然我总是可以手动清除它,但我很好奇是否有办法以编程方式执行此操作.

我在构建项目时遇到以下错误:

当我连接到我的网络服务以检索数据时,手机有时会断开连接,DNS混乱,等等.然后我得到一个UnknownHostException非常好的.

我想要做的是在这里寻找hostName时设置超时:

 response = httpclient.execute(httpget);

我已经设定:

HttpConnectionParams.setConnectionTimeout(httpParameters,timeoutConnection);
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

但他们似乎并不申请HostLookUp.有没有办法在主机查找时设置超时？

编辑
我刚刚发现用户无法修改nslookup hc-dev邮件列表中此帖子的超时.

我将不得不在此时从计时器手动抛出超时异常.

遵循JEP 286:局部变量类型推断描述

我想知道,引入这种限制的原因是什么,如:

Main.java:199: error: cannot infer type for local variable k

    var k = { 1 , 2 };
        ^   
(array initializer needs an explicit target-type)

Run Code Online (Sandbox Code Playgroud)

所以对我来说逻辑上它应该是:

var k = {1, 2}; // Infers int[]
var l = {1, 2L, 3}; // Infers long[]

因为Java编译器已经可以正确地推断出数组的类型:

void decide() {
    arr(1, 2, 3);  // call  void arr(int ...arr)
    arr(1, 2L, 3); // call  void arr(long ...arr)
}

void arr(int ...arr) {
}

void arr(long ...arr) {
} …

如何从操作栏的右上角删除设置图标？当我在我的实际三星galaxy s3手机上模仿时,它不存在,但是,当我在Nexus 7的AVD上模拟时,它出现了.这是我的菜单的代码:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/action_settings"/>
    <item
        android:id="@+id/main_menu_actionbutton"
        android:orderInCategory="100"
        android:showAsAction="always"
        android:title="@string/Menu"/>
</menu>

我在我的应用级build.gradle中出现错误,在我使用的第一个支持库上,它告诉我所有com.android.support库必须使用完全相同的版本规范,并且它找到了版本27.1.1和26.0.2.在我的app级build.gradle中,没有使用26.1.0的行.此外,所有的compile陈述都被改为implementation,compileSdkVersion27 targetSdkVersion岁,27岁.为了找到罪魁祸首,我跑了:

./gradlew -q dependencies app:dependencies --configuration debugAndroidTestCompileClasspath

得到以下输出:

registerResGeneratingTask is deprecated, use registerGeneratedResFolders(FileCollection)

如果我有一个Firebase Firestore数据库,我已经DocumentSnapshot为右边的集合对应的文档检索了一个并存储在document变量中,那么我怎样才能在DocumentSnapshot"用户名"字段中检索该值？该字段具有字符串值.

嗨,我想从resteasy服务器返回一个文件.为此,我在客户端有一个链接,它使用ajax调用rest服务.我想在休息服务中返回该文件.我尝试了这两个代码块,但两个都没有按照我的要求工作.

    @POST
    @Path("/exportContacts")
    public Response exportContacts(@Context HttpServletRequest request, @QueryParam("alt") String alt) throws  IOException {

            String sb = "Sedat BaSAR";
            byte[] outputByte = sb.getBytes();


    return Response
            .ok(outputByte, MediaType.APPLICATION_OCTET_STREAM)
            .header("content-disposition","attachment; filename = temp.csv")
            .build();
    }

在我的应用程序中,我需要使用paypal高级设置定期计费部分,我使用payflow部分执行相同操作.我需要付费PayPal按钮流程(快速结账流程)和信用卡付款才能创建定期个人资料.我的初始请求是这样的:

public static PayPalRedirectAdv PayFlow()
{

    NameValueCollection requestArray = new NameValueCollection()
    {

        {"PARTNER", "PayPal"},             // You'll want to change these 4
        {"VENDOR", "merchantname"},           // To use your own credentials
        {"USER", "username"},
        {"PWD", "abcdenfg"},
        {"TRXTYPE", "A"},
        {"AMT", "1.00"},
        {"CURRENCY", "USD"},
        {"CREATESECURETOKEN", "Y"},
        {"SECURETOKENID", "tokenId generated"},  
        {"RETURNURL", UrlReturn}, 
        {"CANCELURL", UrlCancel},
        {"ERRORURL", lUrlError},
        {"BILLINGTYPE","RecurringBilling"}

    };

    NameValueCollection resp = run_payflow_call(requestArray); // Will call the payflow end point via HttpWebRequest
    if (resp["RESULT"] == "0")
    {
        string mode = "TEST";

我目前有以下MS Access SQL查询,它是Access VBA功能的一部分.它是在前一个问题的帮助下构建的,您可以查看该问题以更好地理解它的工作原理.
