以上代码是我从网络上复制到我的模块（chuangti）中,我在代码是:
Private Sub Command27_Click()
chuangti.fSetACCESSWindow (SW_HIDE)

End Sub
为什么不能隐藏窗体?请高手指点.

提示什么错误?

[OracleRoob]

是不是窗口还没有启动完毕?

[wwwwb]

先要确定是否找到窗口

[milerzhang]

我的程序老是运行到：
MsgBox "除非屏幕上有一个窗口，否则不能隐藏 Access 主窗口!" _
& vbCr & vbCr _
& "Cannot hide Access unless " _
& "a FORM is on screen"

如果哪位高手知道窗体怎么隐藏？请教教我。我的目的就是实现窗体隐藏。谢谢！

在执行chuangti.fSetACCESSWindow (SW_HIDE)前，chuangti是否已经存在并构造完成?

[milerzhang]

楼上的，这句话“chuangti是否已经存在并构造完成?”怎么理解？“chuangti”是一个模块呀？
