超音波檢查
即使連續照射2小時的超音波檢查對胎兒的健康也不會有任何影響。
檢查的時候，建議多喝水，不要排尿，因為如果膀胱是空的，子宮就會移到骨盆的下側，致使檢查難以進行。 
在第18週的時候，可以進行精密超音波檢查，可以得知胎兒個部位的構造是否正常。

C++ 函式參數指標寫法
void swap(int a, int b) // call by value
{
int tmp = a;
a = b;
b = tmp;
}

2012. 3. 18 更新，版本1.0.2

說明:

C#:
string s3 = "Visual C# Express";
System.Console.WriteLine(s3.Substring(7, 2)); // outputs "C#"
System.Console.WriteLine(s3.Replace("C#", "Basic")); // outputs "Visual Basic Express"
Substring從0開始算 

佇列(Queue)是用先進先出的方式處理物件的集合，例如到銀行排隊，先排的人先處理；而堆疊(Stack )是後進先出的集合，例如玩撲克牌排遊戲時，發牌時是從整疊的最上一張拿取。

svn恢復到某一版本，注意一點:恢復到某一版本只有在你本機恢復，在svn server端並沒有恢復，所以想要把svn上的版本也回到那一個版本，必須從你的本機再送交一次，讓新的版本變你想要的那一版。
以下用圖示說明:

Mesh數據的處理
執行D3DXLoadMeshFromX函數完成.X文件的加載後，Mesh的各種數據將存放在頂點緩衝區，頂點索引緩衝區，材質緩衝區，鄰接頂點緩衝區，特效屬性緩衝區，網格緩衝區中。其中，材質緩衝區（包含材質信息和紋理貼圖文件名信息），鄰接頂點緩衝區以及特效屬性緩衝區的地址由 D3DXLoadMeshFromX函數成功執行後返回，其他的緩衝區地址可利用ID3DXMesh接口函數來獲得。
.X網格的渲染和優化就是使用上面緩衝區的數據來進行的。頂點緩衝區給出了整個網格的頂點坐標列表（包括頂點坐標和頂點紋理坐標），頂點索引緩衝區給出了每個三角形面的頂點構成信息（三個頂點的索引值），從而間接給出了整個網格的所有三角形面的頂點信息說明，屬性緩衝區為每個三角形面的一個網格子集編號，即給出了網格的每個三角形面的分組號。具有同一個Subset編號的三角形，將使用相同的材質和紋理對象進行渲染。
Mesh網格的渲染，可以用一個for循環來進行，循環的次數為總的材質數。每一次循環都將那些具有相同Subset子集號的三角形面渲染出來，即渲染每個子集Subset。不過每次循環首先要設置渲染管道線的材質和紋理對象，

D3DXVec3Normalize(vOut, v) 返回向量的單位向量
　說明：返回向量的單位向量，即方向不變長度為 1 的向量
　用法：D3DXVec3Normalize vOut, v
　參數：VOut As D3DVECTOR 返回計算結果的向量
　　　　v As D3DVECTOR 欲計算其單位向量的向量

開始
DX程序第一件事是創建DX對象，相當於初始化DirectX。
LPDIRECT3D9X g_pD3D = Direct3DCreate9( D3D_SDK_VERSION);
if(NULL == g_pD3D) return E_FAILE;
每個程序都是由此開始的，而且寫法都一樣，參數必須是D3D_SDK_VERSION。

DirectX 範例裡面的 CDXUTDialog
CDXUTDialog g_HUD; // manages the 3D UI
CDXUTDialog g_SampleUI; // dialog for sample specific controls
一樣可以用回呼function
g_HUD.Init( &g_DialogResourceManager );
g_HUD.SetCallback( OnGUIEvent );
