我刚刚尝试过，并得到了一个创建窗口句柄的错误。运行以下代码时，

SendMessage调用异常：

私有声明函数SendMessage Lib" user32"别名SendMessageA

（ByVal hwnd As Integer，ByVal wMsg As Integer，ByVal wParam As Integer，ByVal

lParam as Integer）As Integer


Dim testform As New Form2

testform.Hide（）

SendMessage（testform.Handle.ToInt32，& H8000,0,0）


有人知道发生了什么吗？


" CT"写道：

I just tried that, and got an "Error creating window handle" exception on the
SendMessage call when running the following code:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA"
(ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal
lParam As Integer) As Integer

Dim testform As New Form2
testform.Hide()
SendMessage(testform.Handle.ToInt32, &H8000, 0, 0)

Anybody know what''s going on?

Dan，


您可以更改API声明：


私有声明函数SendMessage Lib" user32"别名SendMessageA

（ByVal hwnd As IntPtr，ByVal wMsg As Integer，ByVal wParam As Integer，ByVal

lParam as Integer）As Integer

Dan,

You can change the API Declare to this:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA"
(ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal
lParam As Integer) As Integer
