16 Windows编程——系统内置窗口子类型之edit、ComboBox、ownerbutton、listbox
edit类型的子窗口
ES_MULTILINE：多行输入文本框
窗口的消息：
WL_COMMAND：
EN_CHANGE：当edit窗口内的文本内容改变的时候，edit子窗口给父窗口发送一个WL_COMMAND消息，其通知码是EN_CHANGE。
WM_GETTEXT：
用SendMessage函数给edit窗口发送这个消息，同时，给wparam参数传递我们想要获得的字符个数，lParam传递一个内存块地址，sendMessage函数返回后，
lParam指向的内存中，将保存获得的字符。
WL_GETTEXTLENGTH：
用 SendMessage函数给edit窗口发送这个消息，将wParam和1Param都赋值为NULL，那SendMessage函数，将返回edit中的字符个数，但这个字符个数不包括NULL结尾字符。
edit空间演示源码
#include<Windows.h> LRESULT CALLBACK WindProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam); int WinMain(HINSTANCE hInst, HINSTANCE tmp, LPSTR szCmd, int nShow)
{

WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
WndClass.hInstance = hInst;
WndClass.lpfnWndProc = WindProc;
WndClass.lpszClassName = ClassName;
WndClass.lpszMenuName = NULL;
WndClass.style = CS_VREDRAW | CS_HREDRAW; if (!RegisterClass(&WndClass))
{

TCHAR str[];
int length;
switch (message)
{
case WM_CREATE:

return ;
case WM_SIZE:

cy = HIWORD(lParam);
MoveWindow(editHwnd, , , cx/, cy/, TRUE);
MoveWindow(staticHwnd, cx / , cy / , cx, cy, TRUE);
return ;
case WM_COMMAND:
if (HIWORD(wParam)==EN_CHANGE)
{

length = length > ? : length;
SendMessage(editHwnd, WM_GETTEXT, length, (LPARAM)str) ;
str[length] = '/0';
SetWindowText(staticHwnd,str);
}
return ;
case WM_DESTROY:
PostQuitMessage();
return ;
default:
break;
} return DefWindowProc(hwnd, message, wParam, lParam);
}
运行结果
ComboBox类型的子窗口
ComboBox子窗口的三种主要子类型：
CB_ADDSTRING：在combobox控件的list框中，增加一个字符串，wParam=NULL，lParam符串的指针。
WL_COMMAND：
CBN_SELCHANGE：当combobox中的选项发生变化时，发送这个通知码，其中LOWORD（lParam）就是这个combobox的窗口标识ID。
CB_GETCURSEL：用SendMessage函数，发送这个消息给combobox子窗口，那么这个函数将返回被选中的列表项的索引（索引是从0开始的）。wParam=lParam=NULL.
