[fxtfxt2008]

hello,SWFKIT! i'm sorry for bothering again.i have a few problems,sincerely hope
you answer this.as follows
1.Why can not the code below normal execution
Application.sendMessage(Window.find("CabinetWClass ","test").handle, 0x0010,0,0);//WM_CLOSE

2.in the example bellow,how to determine The third parameter
Application.sendMessage(getMainWnd().handle, 0x0112, 0x800c,0);//WM_SYSCOMMAND

3 why is similar to the following code Is wrong
Application.sendMessage(Window.find("CabinetWClass ","test").handle, WM_SYSCOMMAND,SC_CLOSE,0)
4the Application.sendMessage mothed and the dllimport "user32.dll" * * SendMessage(****) as * mothed ,which is more powerful
can You answer more detailed ?
thank you advance!

It's the same as the function in user32.dll, i.e. it's a wrapper of the function in user32.dll.

To close a window, instead of sending a message, you can use the following code

Window.find("CabinetWClass","test").close();

About the third parameter, you have to look for it in MSDN. And SC_CLOSE is a contant that has not been defined in ffish script, so you will have to use 61536. If you cannot get its value, please try "SC_CLOSE=" on google.

but this is also a problem don't understand .
3 why is similar to the following code Is wrong

Application.sendMessage(Window.find("CabinetWClass","test").handle, WM_SYSCOMMAND,SC_CLOSE,0)

why can't use WM_SYSCOMMAND and SC_CLOSE? is this possible with SWFKIT? Find those values are very troublesome.
