小编fat*_*han的帖子

我在Stackpanel里面有两个网格.第一个网格名为GridX.最初在网格内部有一个文本框的2D数组(RowDefs/ColumnDefs).XAML中的TextBox定义是

<TextBox x:Name="A1" Grid.Row="4" Grid.Column="5" TextAlignment="Center" />

我希望以与GridX的一部分相同的位置以编程方式添加TextBlock.

效果必须是这样的

<TextBlock Grid.Row="4" Grid.Column="5"
HorizontalAlignment="Left" VerticalAlignment="Top" Text="10" FontSize="8"/>

如何添加这个.我试过这个:

TextBlock tblock = new TextBlock();
GridX.SetColumn(tblock, cIndex);
GridX.SetRow(tblock, rIndex);

但失败了.

我再试一次:

int rIndex = Grid.GetRow(txtBox);
int cIndex = Grid.GetColumn(txtBox);                               

TextBlock tblock = new TextBlock();
tblock.VerticalAlignment = VerticalAlignment.Top;
tblock.HorizontalAlignment = HorizontalAlignment.Left;
tblock.FontSize = 8;
tblock.Text = rc[i, j - 1];

Grid.SetColumn(tblock, cIndex);
Grid.SetRow(tblock, rIndex);

txtBox.MaxLength = 1;    

现在问题是TextBlock不可见.TextBox隐藏它.你能帮我吗

我需要在viewDidload事件中获取并显示最后从照片库中拍摄的3张照片而不进行任何点击.

在此步骤之后,当我滚动滚动视图时,我应该获得其他照片3乘3.

你知道用swift做这个的正确方法吗？谢谢.

你能用2.0驱动程序帮助我正确运行"拉(删除)".

我有一个这样的集合,我想删除第一个跟随者字段命名为fethiye的追随者.

{
  "_id": ObjectId("554e05dfc90d3d4dfcaa2aea"),
  "username": "bodrum",
  "followerList": [
    {
      "_id": ObjectId("554e0625a51586362c33c6df"),
      "follower": "fethiye",
      "avatar": "fethiye.png"
    },
    {
      "_id": ObjectId("554e0625a51586362c33c6df"),
      "follower": "izmir",
      "avatar": "izmir.png"
    }
  ]
} 

我该如何修复此查询？

var filter = new BsonDocument("username", "bodrum");
var update = Builders<Person>.Update.Pull("followerList:follower", "fethiye");
Person pr = collection.FindOneAndUpdateAsync(filter, update).Result;

谢谢.

我尝试在版本 2 中设置 Traefik，但DNS_PROBE_FINISHED_NXDOMAIN在我的浏览器中只收到“404 Page not found”或错误。

当我检查路由器的 API 端点时，我可以看到在 Traefik 中启用了我的两个容器并且规则是正确的。

curl http://localhost:8080/api/http/routers

[{"entryPoints":["web","secure"],"service":"gotify-gotify","rule":"Host(`sub2.example.org`)","tls":{"certResolver":"letsencrypt"},"status":"enabled","using":["secure","web"],"name":"gotify@docker","provider":"docker"},{"entryPoints":["web","secure"],"service":"nextcloud-cloud","rule":"Host(`sub.example.org`)","tls":{"certResolver":"letsencrypt"},"status":"enabled","using":["secure","web"],"name":"nextcloud@docker","provider":"docker"}]

但是在“sub2”上我根本没有网站，在“sub”上我得到“404页面未找到”。我为“*”设置了 DNS 条目，因此所有子域都转到同一服务器。

我为 docker 容器设置了以下标签

labels:
traefik.enable: true
traefik.http.routers.nextcloud.rule: "Host(`sub.example.org`)"
traefik.http.routers.nextcloud.entrypoints: "web, secure"
traefik.http.routers.nextcloud.tls.certresolver: "letsencrypt"

这是我的 Traefik 配置traefik.toml

[entryPoints]
  [entryPoints.web]
    address = ":80"
  [entryPoints.secure]
    address = ":443"

[providers.docker]
  exposedByDefault = false
  network = "traefik"

[certificatesResolvers.letsencrypt.acme]
  email = "me@example.org"
  storage = "acme.json"
  [certificatesResolvers.letsencrypt.acme.httpChallenge]
    entryPoint = "web"

[api]
  insecure = true
  debug = true
  dashboard = false

Traefik 本身作为 docker 容器运行。

如何在iOS上解析"MongoDB datetime(ISO Date)"到NSDate(swift和objective-c)

这是json的结果:

}

我也回答了这个问题.

我正在使用UIFeedback Haptic Engine与swift 2.3类似:

let generator = UINotificationFeedbackGenerator()
generator.notificationOccurred(.Warning)

和

let generator = UIImpactFeedbackGenerator(style: .Heavy)
generator.impactOccurred()

今天我遇到了这样一种新的错误,但是找不到问题.你有什么主意吗？

UIFeedbackHapticEngine _deactivate] called more times than the feedback engine was activated

当我在react-native-reanimated尝试运行我的应用程序后安装在我的项目中时，它显示以下错误：

使用版本：

"react-native-reanimated": "^2.8.0",

你能帮我解决这个错误吗？
