可不可以先获得id，然后不需要焦点就能输入。

IDC_EDIT1:BCB中好像不是这样表示控件的ID的...在SDK中在头文件中有如下
的申明:
#define IDC_EDITX 200//300,400.
在BCB中不能直接用IDC_Edit1.

如果你找不到的话是因为你没有装Win32Help.如下:
he GetWindowLong function retrieves information about the specified window. The function also retrieves the 32-bit (long) value at the specified offset into the extra window memory of a window.

LONG GetWindowLong(

HWND hWnd, // handle of window
int nIndex // offset of value to retrieve
);

Parameters

hWnd

Identifies the window and, indirectly, the class to which the window belongs.

nIndex

Specifies the zero-based offset to the value to be retrieved. Valid values are in the range zero through the number of bytes of extra window memory, minus four; for example, if you specified 12 or more bytes of extra memory, a value of 8 would be an index to the third 32-bit integer. To retrieve any other value, specify one of the following values:

Value Action
GWL_EXSTYLE Retrieves the extended window styles.
GWL_STYLE Retrieves the window styles.
GWL_WNDPROC Retrieves the address of the window procedure, or a handle representing the address of the window procedure. You must use the CallWindowProc function to call the window procedure.
GWL_HINSTANCE Retrieves the handle of the application instance.
GWL_HWNDPARENT Retrieves the handle of the parent window, if any.
GWL_ID Retrieves the identifier of the window.
GWL_USERDATA Retrieves the 32-bit value associated with the window. Each window has a corresponding 32-bit value intended for use by the application that created the window.

The following values are also available when the hWnd parameter identifies a dialog box:

Value Action
DWL_DLGPROC Retrieves the address of the dialog box procedure, or a handle representing the address of the dialog box procedure. You must use the CallWindowProc function to call the dialog box procedure.
DWL_MSGRESULT Retrieves the return value of a message processed in the dialog box procedure.
DWL_USER Retrieves extra information private to the application, such as handles or pointers.

Return Values

If the function succeeds, the return value is the requested 32-bit value.

GetWindowLong和SetWindowLong两个的API的参数比较多而且杂,建议你看一下帮助...上面都有的..

我找不到GetWindowLong()的函数声明。
季世平老大，再解释一下可以吗？
还有，哪个GWL_ID是什么？？？

已知窗口句柄(包括控件的句柄)，用下面的方法得到窗口的ID:
UINT ID = GetWindowLong(hWnd, GWL_ID);

已知父窗口和控件的ID，用下面的方法得到控件的窗口句柄：
HWND hWnd = GetDlgItem(hParent, ChildID);

知道了控件Edit的句柄，就可以用SetWindowText来设定Edit的文字了。
