关于为什么不可以用：

Copies the text of the specified window's title bar (if it has one) into a buffer. If the specified window is a control, the text of the control is copied. However, GetWindowText cannot retrieve the text of a control in another application.

WIN7

#include 
   
    #include 
    
     int main(){		TCHAR str[100] = TEXT("Hello World");	HWND hwnd = NULL;	hwnd = FindWindowEx(NULL, NULL, TEXT("CabinetWClass"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("WorkerW"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("ReBarWindow32"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("Address Band Root"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("msctls_progress32"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("ComboBoxEx32"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("ComboBox"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("Edit"), NULL);		SendMessage(hwnd, WM_GETTEXT, 100, (LPARAM)str);	//SendMessage(hwnd, WM_SETTEXT, 0, (LPARAM)str);	MessageBox(NULL, str, TEXT("Cap"), 0);	//wprintf(TEXT("%s\n"), str);	return 0;}
    
   

上面这个还是比较鸡肋的：

需要点击下地址栏才会出现ComboBoxEx32->ComboBox->Edit

测试：

通过点击向下箭头，刷新路径显示

#include 
   
    #include 
    
     #include 
     
      int main(){		TCHAR str[1024] = TEXT("Hello World");	HWND hwnd = NULL;	HWND hToolbat;		hwnd = FindWindowEx(NULL, NULL, TEXT("CabinetWClass"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("WorkerW"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("ReBarWindow32"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("Address Band Root"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("msctls_progress32"), NULL);	hToolbat = FindWindowEx(hwnd, NULL, TEXT("ToolbarWindow32"), NULL);		SendMessage(hToolbat, WM_LBUTTONDOWN, MK_LBUTTON, MAKELONG(0, 0));	SendMessage(hToolbat, WM_LBUTTONUP, MK_LBUTTON, MAKELONG(0, 0));	SendMessage(hToolbat, WM_LBUTTONDOWN, MK_LBUTTON, MAKELONG(0, 0));	SendMessage(hToolbat, WM_LBUTTONUP, MK_LBUTTON, MAKELONG(0, 0));			hwnd = FindWindowEx(hwnd, NULL, TEXT("ComboBoxEx32"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("ComboBox"), NULL);	hwnd = FindWindowEx(hwnd, NULL, TEXT("Edit"), NULL);		if(hwnd == NULL)	{		wprintf(L"%s\n", L"error");		return -1;	}		SendMessage(hwnd, WM_GETTEXT, 1024, (LPARAM)str);		MessageBox(NULL, str, TEXT("Caption"), 0);	return 0;}
     
    
   

利用好wmic命令
