同一个程序里面启动多个WINDOWS
第二个立即返回了
改成 OnExplicitShutdown

OnLastWindowClose

应用程序在最后一个窗体关闭时，或调用Shutdown方法时才会关闭

l         OnMainWindowClose

An application shuts down when either the main window closes, or Shutdown is called.

应用程序在主窗体关闭时，或调用Shutdown方法时才会关闭

l         OnExplicitShutdown

应用程序只有在调用Shutdown方法时才会关闭。

C#中让ListBox支持文件路径的拖放
有时，我们程序，需要加载一个文件列表，这个列表，通常用ListBox来存放，为了方便操作，让listBox支持拖放入文件的路径，是个非常好的功能，在.NET里面实现这个功能，是非常方便，只需要3个步骤：

将 ListBox 的 AllowDrop 属性设为 true
在 ListBox 的 DragOver 和 DragEnter 事件中处理
void ListBox1DragEnter(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.All;
}

void ListBox1DragOver(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.All;
}
上面的 e.Effect 可以根据实际情况，调节不同的值，不过，如果不确定，就用默认的All

3. 处理拖放事件

void ListBox1DragDrop(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(DataFormats.FileDrop, false))
{
String[] files = (String[])e.Data.GetData(DataFormats.FileDrop);
foreach (String s in files)
{
(sender as ListBox).Items.Add(s);
}
}

 // TODO: 在此添加控件通知处理程序代码
HANDLE Hand  = CreateToolhelp32Snapshot(TH32CS_SNAPMODULE, 2256);
MODULEENTRY32 lppe;
memset(&lppe,0,sizeof(MODULEENTRY32));
 lppe.dwSize = sizeof(MODULEENTRY32);
BOOL  found = Module32First(Hand, &lppe);
CFile myFile;

if ( myFile.Open( _T(“r:\\myfilef.dat”), CFile::modeCreate |  
 CFile::modeReadWrite, NULL ) )
{
 /*myFile.Write( szBuffer, sizeof( szBuffer ) );
 myFile.Flush();
 myFile.Seek( 0, CFile::begin );
 nActual = myFile.Read( szBuffer, sizeof( szBuffer ) ); */

 while(found)
 {
 DWORD Add1 = DWORD(lppe.modBaseAddr);
DWORD Add2  = Add1 + lppe.modBaseSize;
DWORD index  = DWORD(lppe.modBaseAddr);
 
  {
  
   myFile.Write(lppe.modBaseAddr,  lppe.modBaseSize-4);
  
  }
   found = Module32Next(Hand, &lppe);
 }
  CloseHandle(Hand); // 释放快照句柄

我写了一个简单的函数，调用一下就可以把DLL和EXE的内存里的信息全部导到文件里！到时再慢慢查吧！

CopyFromScreen截屏

传统截屏
#region 导入函数
      
        [DllImport("gdi32.dll")]
        private static extern IntPtr CreateDC(string lpszDriver, string lpszDrivse, string lpszOutput, Int32 lpInitData);

        [DllImport("gdi32.dll")]
        private static extern IntPtr CreateCompatibleDC(IntPtr hdc);

        [DllImport("gdi32.dll")]
        private static extern int GetDeviceCaps(IntPtr hdc, Int32 nIndex);

        [DllImport("gdi32.dll")]
        private static extern IntPtr CreateCompatibleBitmap(IntPtr hdc, int nWidth, int nHeight);

        [DllImport("gdi32.dll")]
        private static extern IntPtr SelectObject(IntPtr hdc, IntPtr hgdiobj);

        [DllImport("gdi32.dll")]
        private static extern int BitBlt(IntPtr hdcDest, int nXDest, int nYDest,
                 int nWidth, int nHeight, IntPtr hdcSrc, int nXSrc, int nYSrc, UInt32 dwRop);

        [DllImport("gdi32.dll")]
        private static extern int DeleteDC(IntPtr hdc);

        #endregion

 现在截屏简单多了

 Console.WriteLine(DateTime.Now.Millisecond.ToString());
            System.Drawing.Bitmap photo = new System.Drawing.Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
            System.Drawing.Graphics graphic = System.Drawing.Graphics.FromImage(photo);
            graphic.CopyFromScreen(0, 0, 0, 0, new System.Drawing.Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height));
            photo.Save(@”r:\aa.jpg”, System.Drawing.Imaging.ImageFormat.Jpeg);
            Console.WriteLine(DateTime.Now.Millisecond.ToString());

CopyFromScreen 方法对于将一个图像放置于另一个图像顶部非常有用。若要指定源颜色和目标颜色的混合方式，请使用 CopyFromScreen 方法之一，该方法采用 CopyPixelOperation 参数。

做个模拟时钟，搞了几个图片，然后不想放在外部，想内嵌，结果发现一个内嵌，不知道微软为什么搞那么多东东。

项目属性里面有个资源；然后文件属性有个编译选项，并且选择项还不少。

直接使用 Assembly.GetManifestResourceStream方法来读取资源数据流。其中资源名为

Namespace + FolderName + Filename
Stream strm = Assembly.GetExecutingAssembly().GetManifestResourceStream(“MyNameSpace.Images.logo.bmp”);
Image image = new Bitmap(strm);
pictureBox1.Image = image;

[100分] 问关于uri使用某个dll image 资源的问题？急,在线等…..分不够可以再加多少都可以
http://topic.csdn.net/u/20070906/15/a01619d6-f595-4fd8-ae3d-d77e9f1121c5.html
我在一个dll（类ImageControl）中添加了一个on.gif的资源，然后在application对其进行引用。下面是一个按钮的click事件：

private void button1_Click(object sender, RoutedEventArgs e)
{
  image1.Source = new BitmapImage(new Uri(“Pack://application:,,,/ImageControl;component/on.gif”));
}

最初我也各楼主一样只写了new Uri(“/ImageControl;component/on.gif”)，运行时报错说找不到资源，但后来经过查找在前面加上了Pack://application:,,,后就可以了。

又碰到转义字符，估计这个是LINUX下JAVA生成的XML，所以只有
。

没有办法，只好整理了弄下。
if (c == ‘&’) {
buf.Append (“&”);
并且XML每次还得先把&转换成&。如果LOADXML，" 就成了："&

http://cse-mjmcl.cse.bris.ac.uk/blog/2007/02/14/1171465494443.html
In c#: xml = Regex.Replace(xml, “&\\#x(?:0[0-8BCEF]|1[0-9A-F]);”, “”);
这人狠，直接干掉··

http://www.csharper.net/blog/escape_xml_string_characters_in_c_.aspx
xml = xml.Replace( “&”, “&” );
xml = xml.Replace( “<”, “<” );

但是好像不区分大小写？

XML文档中使用多个关键字，如果XML文档中使用这些关键字，则需要转义。这些字符如下：

l         “&”用替换“&amp”；

l         “<”用替换“&lt;”；

l         “>”用替换“&gt;”；

l         “””用替换“&quot;”；

l         空格用替换“&nbsp;”。

XML标准中还定义了其它一些转义符，用于显示一些特别字符，如各种货币的符号（英镑：&pound;）、商标符号（&#8482;）等。

Character Name  Entity Reference  Character Reference  Numeric Reference
Ampersand  &amp;  &  &#38;#38;
Left angle bracket  &lt;  <  &#38;#60;
Right angle bracket  &gt;  >  &#62;
Straight quotation mark  &quot;  ”  &#39;
Apostrophe  &apos;  ’  &#34;
http://support.microsoft.com/?scid=kb%3Ben-us%3B316063&x=7&y=9
微软直接搞了个private void ReplaceSpecialChars(long linenumber)

我干脆全部替换一遍：
string s = xn.InnerText;
s = Regex.Replace(s, “&#xD;&#xA;”, “\r\n”);
s = Regex.Replace(s, “&nbsp;”, ” “);
s = Regex.Replace(s, “&#xD;”, “\r\n”);
s = Regex.Replace(s, “&#xA;”, “\r\n”);
s = Regex.Replace(s, “&quot;”, “”");
s = Regex.Replace(s, “&lt;”, “<”);
s = Regex.Replace(s, “&gt;”, “>”);
s = Regex.Replace(s, “&apos;”, “\”);
s = Regex.Replace(s, “&amp;”, “&”);

虽然据说２、System.Text.Regex(Regular Expression正则表达式)，大家都估计到它的效率不高，虽然它支持忽略大小写。
//另外还碰到个好玩的事情，如果外接了显示器，并且拖过去了程序，如果拔掉，这个程序就找不回来了。得右键菜单－移动，然后拖回来。

表显示了 XML 输出中转义的字符。除 UserData 元素（其中包含用户提供的非转义数据）外，其他所有元素和属性均发生转义。UserData 元素是调用 TraceData 方法的结果。

今天转悠转悠，跑到了OPHONE网站去了。
首先去的是：http://www.mmarket.com/
然后进入了开发者社区：http://dev.chinamobile.com/cmdn/supesite/
里面的资料还有些，看了看OPHONE SDK的一点编程资料
从DEMO又调到了：http://www.ophonesdn.com/documentation/ophone/gettingstarted/hello_ophone.html
这是一个源码：
http://www.ophonesdn.com/documentation/ophone/samples/ophoneapps/HomeAPIDemo/src/oms/samples/home/HomeAPIDemoActivity.java.html

感觉还是太复杂了

看来没有可视化界面编程，如果做复杂界面程序，估计是个痛苦的事情
至于编程也是大同小异。
也是NEW，然后设置属性，最后画出来
不过CANVAS好像很强悍的样子

令人抓狂的silverlight3开发环境构建

想弄下silverlight 3 ，我已经安装了VS2008 SP1。
到官网一看：东西不少
Microsoft® Silverlight™ 3 Tools for Visual Studio 2008 SP1
Microsoft® Silverlight™ 3 SDK
Microsoft Silverlight 3 脱机文档

不过SDK还不到10M。而2.0版本的却有
Microsoft® Silverlight™ 2 软件开发工具包 55.8 MB

安装了SDK，说我原有版本更高。这也是我登录MS网站提示我安装的。
于是就卸载。然后安装了SDK

再安装TOOLS，结果提示：
Action: Downloading Items…

[9/1/2009, 11:35:39] (IronSpigot::CompositeDownloaderT<class IronSpigot::RetryingDownloaderT<class IronSpigot::WinHttpDownloader,class IronSpigot::BitsDownloader,class IronSpigot::UrlMonDownloader,class IronSpigot::FileAuthenticity> >::PerformAction) Downloading http://go.microsoft.com/fwlink/ to R:\TEMP\Silverlight 3.0 Tools\Silverlight_Developer.exe

去下载了一个，安装了后继续：
提示版本不对，只好卸载，再重新安装TOOLS

亏我还是官网下载的：http://download.microsoft.com/download/0/D/7/0D76C405-E0E5-43CC-89D3-18243A4FCA86/Silverlight.3.0_Developer.exe
下载SDK的时候看到的：
在安装 Silverlight 3 SDK 前，请删除 Silverlight 3 SDK Beta。

如果您已安装或计划安装 Microsoft Silverlight Tools for Visual Studio 2008，请直接跳过 Silverlight SDK 的安装。Microsoft Silverlight Tools 将安装 Silverlight 3 SDK。有关此方面的更多信息，请单击此处。

若要生成 Silverlight 3 应用程序，您可以在此处安装 Silverlight 3 for Developers

结果提示安装失败
WINHTTP_CALLBACK_STATUS_REQUEST_ERROR error: error=12002, result= 2. Percentage downloaded=19

[9/1/2009, 12:1:19] Action complete

只好又重新手工下载··然后安装

结果这个···
居然还是要下载······
我彻底无语了········

～～～～～～～～～
1. 先打VS2008Sp1的包
http://www.microsoft.com/downloadS/details.aspx?familyid=27673C47-B3B5-4C67-BD99-84E525B5CE61&displaylang=zh-cn

2. 装 Silverlight3_Tools.exe
http://www.microsoft.com/downloads/details.aspx?displaylang=zh-cn&FamilyID=c22d6a7b-546f-4407-8ef6-d60c8ee221ed

3. 装silverlight_sdk.exe

http://www.microsoft.com/downloads/details.aspx?familyid=8D933343-038F-499C-986C-C3C7E87A60B3&displaylang=zh-cn

1：安装VS2008

下载地址：http://msdn.microsoft.com/en-us/vs2008/products/cc268305.aspx

2：给VS2008打SP1补丁

下载地址：http://www.microsoft.com/downloads/details.aspx?FamilyID=FBEE1648-7106-44A7-9649-6D9F6D58056E&displaylang=en

3：安装VS2008专用SilverLight开发插件

VS2008 SP1默认不安装Silverlight模版。需要手动下载Microsoft Silverlight Tools for Visual Studio 2008下载地址是：

http://www.microsoft.com/downloads/details.aspx?FamilyID=50a9ec01-267b-4521-b7d7-c0dba8866434&DisplayLang=en

有多种语言版本。

下载前请按网页上的，提示卸载以前任何SL1.1或以前版本的 相关补丁。

下载安装后，新建工程，会出现SilverLight模版选项，此时，VS2008也能和Microsoft Expression Blend 结合使用了。

（图用的博客园一位同仁的）

最后，注意安装顺序。

（1），卸载Silverlight Runtime(客户端插件)，经过个人测试，这步好像是必须的，不然第2步到最后会失败。如果失败，从第1步重来

（2），安装Microsoft Silverlight Tools for Visual Studio 2008

（3），然后安装Silverlight Runtime

安装了BBTHEMS，介绍可以参考：http://blog.iibetter.com/?p=10140 Wordpress主题下载该主题采用了HELLOFLASH作为幻灯片插件：参考了：

然而还是时而好，时而坏，一怒之下，决定换个插件。

上网看到：

http://paranimage.com/5-wordpress-slideshow-plugins-for-featured-posts/
好像第一个不错的样子：D13design提供的一个WordPress插件，以Javascript幻灯片动画的形式展示推荐内容。包含图片，标题和摘要。可选输出5篇或10篇，后台选择要输出哪些文章。幻灯片样式可设为循环播放，只播放一次或手动导航，以及其它一些方便的设置。下载后安装，似乎正常，可是配置页面总是显示不完整，提示如下：
<b>Fatal error</b>:  Maximum execution time of 30 seconds exceeded in <b>D:\PhpNow\htdocs\wp\wp-includes\plugin.php</b> on line <b>385</b><br />
看了看代码：
global $post;
foreach($myposts as $post) :
setup_postdata($post); ?>
<option value=”<?php echo(the_ID()); ?>” <?php if($post->ID==$temp){ echo(“selected”); } ?>><?php echo $post->ID; ?>: <?php the_title(); ?></option>
<?php endforeach; ?>
</select>

看来是由于我的BLOG条目2000多条，太多了，导致超时了。

找了找资料，改成：
$querystr = “       SELECT *       FROM wp_posts       ORDER BY wp_posts.post_date DESC       LIMIT 0,20        “;
global $wpdb;
$pageposts = $wpdb->get_results($querystr);
foreach ($pageposts as $topten)
{
$postid = $topten->ID;
$title = $topten->post_title;
?>
<option value=”<?php echo $topten->ID; ?>”
<?php
if($topten->ID==$temp){ echo(“selected”); } ?>>
<?php echo $topten->ID; ?>:
<?php echo $topten->post_title; ?>
</option>      <?php }; ?>

只显示前面20个终于正常了··参考资料：

Look at the sqlite.org: http://www.sqlite.org/lang_expr.html

last_insert_rowid() Return the ROWID of the last row insert from this connection to the database.

It returns last inserted rowid inside connection! You always do open and close connection while querying database. Iif you query \’last_insert_rowid()\’ you do tha same: open new connection and then you get 0.

I know all that, but i have the same problem. I\’m using microsoft visual studio express C# with tableadapters. All queries are like: this.tableadapter.query(parameters).
~
Change your SQL to:

"insert into people (Name) values(@Name);
 SELECT last_insert_rowid() AS RecordID;";

Then call ExecuteScalar() on it instead of ExecuteNonQuery() to get the rowid.

Also your table definition should be:

CREATE TABLE People (RecordID INTEGER PRIMARY KEY AUTOINCREMENT, Name VARCHAR);

Robert
~
ExecuteScalar方法返回的类型是object类型，这个方法返回sql语句执行后的第一行第一列的值，由于不知到sql语句到底是什么样的结构（有可能是int，有可能是char等等），所以ExecuteScalar方法返回一个最基本的类型object，这个类型是所有类型的基类，换句话说：可以转换为任意类型。

ExecuteNonQuery方法是用来执行insert、delete、update语句的，由于这些语句执行后只有一个结果：“影响了**行”，所以ExecuteNonQuery方法返回的是影响的行数（int）。

虽然SQL中列的name本身就是字符串类型，但是你通过dataReader["name"]这种方式访问这个字段，必须强制类型转换，因为dataReader["name"]就像一个数组，数组中的每个元素的类型都应该一样，所以dataReader[]这个数组中的元素类型也被定义为object类型，以方便转换。

int.Parse(("select max(id) from [tb]").ToString())+1);

select top 1 id from [tb] order by id desc

select SCOPE_IDENTITY()

I need something like: http://sqlite.phxsoftware.com/forums/p/1029/4441.aspx#4441

INSERT INTO Timeline (name, ts)
SELECT @name, @ts
WHERE NOT EXISTS (SELECT 1 FROM Timeline WHERE name=@name AND ts = @ts);

It works fine with insert. I was wondering if update can be added to the above statement.

treeview esc

void treeType_AfterLabelEdit(object sender, NodeLabelEditEventArgs e)
        &leftsign;
            Console.WriteLine(e.Label);

            &leftsign;
                e.Node.EndEdit(true);
                e.Node.Remove();
            &rightsign;

  CancelEdit  获取或设置指示是否已取消编辑的值。
  Label  获取与树节点关联的新文本。
  Node  获取包含待编辑文本的树节点。

如果用户按 Esc 取消编辑或没有修改标签文本就按 Enter，此属性的值则为 nullNothingnullptrnull 引用（在 Visual Basic 中为 Nothing）。如果用户编辑标签文本，此属性的值则为新的标签文本。即使编辑的标签文本最后的值与其原始值相同，也是如此。

        ~
        I suggest that you set a flag in the BeforeLabelEdit event and reset the
flag in AfterlabelEdit. In KeyDown if flag and KeyCode=vbEscape then you
remove the Node.

Another method is just to add the node with a default name and have the user
to delete the node if he wants to. I believe this is more like the Windows
style.

我在treeView中新增节点，并把它处于可编辑状态。但如果我想用Esc键退出新增节点的编辑状态，并把它删除，就调用了treeview的 keydown事件。但如何在treeview的AfterLabelEdit中调用keydown事件呢？请高手指点！！！！！

        fDtrControl
The DTR (data-terminal-ready) flow control. This member can be one of the following values.

Value Meaning
DTR_CONTROL_DISABLE
0×00
 Disables the DTR line when the device is opened and leaves it disabled.
 
DTR_CONTROL_ENABLE
0×01
 Enables the DTR line when the device is opened and leaves it on.
 
DTR_CONTROL_HANDSHAKE
0×02
 Enables DTR handshaking. If handshaking is enabled, it is an error for the application to adjust the line by using the EscapeCommFunction function.
