如图所示,我想要的结果是怎么设置才能让挡住图片的对话框不把图片挡住,意思就是透明,当然输密码的对话框我也要透明的,要能看见图片,前提是依然可以输密码哈,不是隐藏,本人接触VB时间不长,希望高手指点一下.
回一楼所答,是label控件

label的backstyle设为0即可

麻烦说下你所说的对话框是什么控件

两种办法。
1、去下载一套支持透明的窗体 下载地址问百度
2、使用函数SetLayeredWindowAttributes

Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As Long
Private Const WS_EX_LAYERED = &H80000
Private Const GWL_EXSTYLE = (-20)
Private Const LWA_ALPHA = &H2
Private Const LWA_COLORKEY = &H1
Private Sub Form_Load()
Dim rtn As Long
rtn = GetWindowLong(hwnd, GWL_EXSTYLE)
rtn = rtn Or WS_EX_LAYERED
SetWindowLong hwnd, GWL_EXSTYLE, rtn
SetLayeredWindowAttrib
