设计需求:
能够提供基本的日常的备忘记录功能,相对于直接的纯文本记录,树形图记录具有层次结构清晰的优势
软件采用mvp设计模式设计app主要部分
主要交互功能依赖于树形微件容器,结点微件设计,及其对应模型Model的设计:
树形布局(ViewGroup)定义该控件可以做出的功能应答和行为
比如支持控件拖动,哪些控件可以捕获拖动操作Action
缩放行为(通过哪些行为触发缩放,
比如双击简单缩放还是多指无级调节)
树形图的连线采用了google提供的库:
android.graphics:
android.graphics.Path;
android.graphics.Canvas
使用二次贝塞尔曲线样式
同时采用了兼容老版本android的nineoldadroids动画库
结点绘制/编辑
该过程需要考虑的细节较多,比如在树形结点发生变化时,为了将树形图正确绘制编辑后的结果(布局),需要进行结点遍历,各级控件必要的测量,体会到了不小的开销
对于结点的添加,有两种情况
- 被操作结点有父节点,则可以执行兄弟结点的添加操作
- 在任何时候,都可以为某个结点添加孩子结点
结点的编辑采用dialog弹窗的形式提供编辑窗口
提供一键清除内容的操作
TreeView
Tree Model
实现可序列化接口,以便文件的保存和读取
提供了一系列遍历计算和测量行为,为TreeView布局提供操作支持
NodeView
NodeView自定义控件是基于TextView设计的,内涵体现在Node Model上
Node Model(同样实现可序列化接口,以便文件的保存和读取)
为结点设计一系列的状态值属性
主要的UI:EditMapActivity
文件方面
使用recyclerView来呈现memo(导图)文件的可滚动列表
提供存储路径显示
同时,列表中的内容扫描到的指定存储路径下的memo文件(序列化存储)
将其显示在recyclerView中
通知方面
当用户请视图切换到其他视图时,会提醒用户是否完成保存,以免数据丢失
.NET SystemInformation.PrimaryMonitorMaximizedWindowSize显示大于PrimaryMonitorSize
在Winforms应用程序上工作的代码设置初始窗口状态。
它使用Systeminformation.PrimaryMonitorMaximizedWindowSize 。
通常程序似乎function，但是当我在debugging器中看到Systeminformation时，我看到以下内容：
PrimaryMonitorMaximizedWindowSize ： Width = 1696， Height = 1026
PrimaryMonitorSize ： Width = 1680， Height = 1050
PrimaryMonitorSize是我的显示器的分辨率，这是有道理的。
PrimaryMonitorMaximizedWindowSize 1026高度感觉正确（1050 – 1026 = 24）
24像素似乎是Windows任务栏的大小。
我怎么能告诉我的应用程序窗口是前景窗口
只有在本地文件较旧时才能下载文件
如何将另一个应用程序的窗口句柄最小化到系统托盘？
有没有办法通过局域网caching和分发Visual Studio更新？
.net开源和运行平台select
然后我解锁并调整了Windows任务栏的两倍。
使用像素标尺测量，它显示为大约80像素。 不过，我现在得到这个PrimaryMonitorSize ： Width = 1680， Height = 984 。 实际的窗口区域似乎在970像素左右。
某处.NET正在获得“有趣”的价值，至less从像素的angular度来看是没有意义的。
这些价值从哪里来？
我怎样理解这些价值呢？
WPF .NET应用程序崩溃，comboBox和菜单事件未在具有Windows 10 Creator Update，.NET 4.7或KB4034658的平板电脑上触发
灰色的WinForm应用程序除了打开对话框
我应该在哪里为我的应用程序生成临时文件？
将VS MBCS源代码expression式转换为Unicode
在辅助显示器上全屏显示
不是说这将是最好的答案，但我会尽力解决这个问题。
SystemImformation在user32 DLL中调用至少两个本地API调用。
GetSystemMetrics （1）
SystemParametersInfo （2）
（1）和（2）用于从下表中引用
有了一个小帮手（见这个答案的结尾），我获得了以下值，基本上可以洞察所观察到的行为。 在下表中，我显示了属性，我的框中的值以及调用了哪个本机API和提供的参数。 例如“（1）32”表示以32作为参数调用GetSystemMetrics 。 两个数字表示API被调用两次。
| Systeminformation | Value | native api | --------------------------------------------------------------------------------------- | FrameBorderSize | {Width=8,Height=8} | (1) 32 33 | PrimaryMonitorMaximizedWindowSize | {Width=1296,Height=916} | (1) 61 62 | PrimaryMonitorSize | {Width=1280,Height=1024} | (1) 0 1 | WorkingArea | {X=0,Y=0,Width=1280,Height=984} | (2) 48
PrimaryMonitorSize的大小实际上就是你的视频卡报告的大小（API也提到了一个相当于GetDeviceCaps调用）。
由于WorkingArea是除了停靠的工具栏和任务栏以外的屏幕边界，如果您只有一个任务栏 ，则可以推断我的任务栏的高度为1024-984 = 40像素左右。
PrimaryMonitorMaximizedWindowSize是窗口应该覆盖工作区域的大小， 不包括窗口边框。 由于FrameBorderSize在两个方向上都是8，所以width和heigth得到2 * 8 = 16加上了WorkingArea大小，因此给出了1296和916的大小以适合我的WorkingArea 。
如果我解锁我的任务栏，并调整它的工作区的新值WorkingArea:{X=0,Height=942}显示额外的行是42像素。
如何转储属性
foreach(var p in typeof(Systeminformation).GetProperties().OrderBy(n => n.Name)) { Console.WriteLine("{0}:{1}",p.Name,p.GetValue(null,null)); }
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.Exception Details: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Source Error:
Line 37: protected void Application_Start(Object sender, EventArgs e)
Line 38: {
Line 39: AppStartLogger.ResetLog();
Line 40: AppStartLogger.WriteLine("Starting AspDotNetStorefront...");
Line 41:
Source File: e:\Just\JustWeb\App_Code\Global.asax.cs Line: 39
Symptoms
Accessing the site results in an "Attempted To Read Or Write Protected Memory" error.
Cause
There are 2 potential causes of this issue:
1 - A site running a version of the ASPDNSF software older than 7.0.2.5 is attempting to run in a medium-trust hosting environment.
2 - A site running a version of the ASPDNSF software older than 7.0.2.5 is running on a host that has just applied the .NET 3.5 SP1 upgrade to the servers.
NOTE: In both of these cases, the problem lies with the environment the software is running in, as configured by the host. These are not flaws in the software, and are beyond our control.
Procedure
The best solution (regardless of which of the 2 causes above is creating your issue) is to upgrade to version 7.0.2.5 SP1 or higher of the ASPDNSF software. Those later versions can run natively in medium-trust (thus avoiding issue #1) and work fine with the latest .NET service pack (which didn't even exist before then for us to test against).
If upgrading is not an option at the moment, there are other workarounds for each possible cause. Note that these are the ONLY workarounds. We can provide no other advice than these steps:
Medium Trust:
1 - First, have the host or server admin apply the Microsoft-created hotfix available at
http://connect.microsoft.com/VisualStudio/Downloads/DownloadDetails.aspx?DownloadID=6003
2 - Contact support and request a special medium-trust build of the software. We will need a valid order number to provide that.
3 - Move to a full-trust environment (this may mean switching hosts).
.NET 3.5 SP1 Patch:
1 - Have the host roll back the changes on the server, or move your site to a server that has not had the patch applied.

If you are using aspdotnetstorefront and are getting the following error: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
then please contact aspdotnetstorefront in regards to the error as you will have to upgrade your aspdotnetstorefront storefront application to version 7.0.2.5 SP1 or version 7.1.0.0 if the .NET 3.5 service pack is installed.
If you are not using aspdotnetstorefront and are getting this error, you will need to verify that you code works with the lates dotnet service packs for all versions. This error is usually remoting related, but not always.

该问题由以下几点导致的
1、传递参数时，参数没传对，参数格式：#{xxx}，要和java接口类中的形参相同
2、select标签返回的int类型，与数据库中的money类型对应不上(博主遇到这个问题，最后排查是数据类型二边没对应上，哈哈)
c#-System.Drawing.Bitmap和System.Windows.Media.Imaging.WriteableBitmap之间的区别
2和有什么区别？一些例子会很棒！
解决方法:
Silverlight中没有System.Drawing.Bitmap.
如果要在.NET框架中与Silverlight中的WritableBitmap之间进行比较,则差异很大. WritableBitmap是位图的简单表示,具有很少的构造函数或操纵方式.使用位图可以执行的大多数操作都需要通过Pixels数组实现.
