有个DW：dw_long，按焦点顺序有列a,b,c
在一个按钮点击事件中加入以下代码：
dw_long.SetColumn("a")
dw_long.SetFocus()
keybd_event(9, 0, 0 , 0 ) // 按下tab
keybd_event(9, 0, 2, 0 ) // 释放tab
执行后，列b获取了焦点
将代码改成：
dw_long.SetColumn("a")
dw_long.SetFocus()
keybd_event(9, 0, 0 , 0 ) // 按下tab
keybd_event(9, 0, 2, 0 ) // 释放tab
dw_long.SetColumn("a")
本意是想最终焦点还是在列a上但发现代码执行后的结果是，焦点还是在列b
如果我改成：
dw_long.SetColumn("a")
dw_long.SetFocus()
keybd_event(9, 0, 0 , 0 ) // 按下tab
keybd_event(9, 0, 2, 0 ) // 释放tab
dw_long.SetColumn("a")
dw_long.SetColumn("b")
这时候执行结果是焦点在列c了。
为什么会这样呢？我是想在模拟了tab键动作后，再自己定位焦点，但是发现执行的结果却是取了代码中最后setcolumn的列，然后才模拟了tab动作...
请问我应该怎么做才能达到模拟了tab键后再自己定位焦点在其他列上
------解决方案--------------------
dw_long.SetColumn("a")
dw_long.SetFocus()
keybd_event(9, 0, 0 , 0 ) // 按下tab
keybd_event(9, 0, 2, 0 ) // 释放tab
dw_long.post SetColumn("a")
