大家好，今天要介绍的是和主框架Frame相关的几个API，之前我也在一篇文章中提过一些，没看过的家人可以看一下：
C# Solidworks二次开发：获取主窗口API和创建新活动窗口API详解_solidworks二次开发c#-CSDN博客
下面介绍一下今天要讲的几个API：
（1）第一个为GetHwnd，这个API的含义为获取主框架的窗口句柄（备注：除了×64应用以外的），下面是其API的具体解释：
其没有输入参数，输出参数为handle。
（2）第二个为GetHwnd×64，这个API的含义为获取64为应用程序中主框架的窗口句柄，下面是其API的具体解释：
其参数同上。
（3）第三个为GetModelWindowCount,这个API的含义为获取此框架的子模型窗口数，下面是API的具体含义：
其没有输入参数，输出参数为窗口数量。
（4）第四个为ShowModelWindow，这个API的含义为显示客户端模型窗口，下面是API的具体解释：
官方的使用例子，如下所示：
This example shows how to switch documents by opening documents in their own and client model windows.
//----------------------------------------------
// Preconditions:
// 1. Verify that the specified documents to open exist.
// 2. Open the Immediate window.
//
// Postconditions:
// 1. Opens the specified documents in their own
// and client model windows.
// 2. Closes all open documents.
// 3. Examine the Immediate window.

swApp.CreateNewWindow();
swFrame = (Frame)swApp.Frame();
modelWindows = (object[])swFrame.ModelWindows;
Debug.Print("Open documents in their own windows:");
foreach (object obj in modelWindows)
{
swModelWindow = (ModelWindow)obj;
//Get the model document in this model window
swModelDoc = (ModelDoc2)swModelWindow.ModelDoc;
//Rebuild the document
swModelDoc.EditRebuild3();
swModelDoc = null;
//Show the model window
Debug.Print("");
swFrame.ShowModelWindow(swModelWindow);
//Get and print the model window handle
HWnd = swModelWindow.HWnd;
Debug.Print(" Model window handle: " + HWnd);
//Get and print the model title as it is seen in the model window's title bar
Debug.Print(" Model title as it seen in the model's window's title bar: " + swModelWindow.Title);
}
strFolder = "";
//Specify true to close all documents, specify false to close
//only the documents not modified
swApp.CloseAllDocuments(true);
}
/// <summary>
/// The SldWorks swApp variable is pre-assigned for you.
/// </summary>

}
上面就是今天要介绍的四个API，都是和主框架有关的。
我们下篇文章再见。
