ساخت باتن کشویی

بسیار ساده ولی پر دردسر 

      Btn0        Bt t1

Btn1        Btnt2

Btn2       Btnt3

Btnt4                   

طبق نام های بالا  کنترل هایی از نوع باتن  در فرم ساخته شده در کنار هم و زیر هم دقیقا مثل موارد فوق الذکر، تابعی نوشته شد که در زمان اتفاق افتادن رویدادکلیک باتنی از باتن های سمت چپ   کل باتن های سمت راست به زیر آن انتقال یابد .

 Function Btn(Bt As Control3) As Doble

For i=1 to 4

Controls("Btnt" & i).Left=Bt.Left+300

 موقعیت پراپرتی TOP هر یک از کنترل های سمت راست میشود ( فرضا Btnt1 میشود Btn0.Top به اضافه ی عرضش و Btnt2 میشود Btn0.Top + Btn.Height +Btnt2.Height

Controls("Btnt" & i).Top=Bt.Top+Bt.Height+(i-1)*Controls("Btnt" & i).Height

(Btn=Controls("Btnt4".Top

Next

یا بصورت زیر 

Function Btn(Bt As Control) As Double

b = Bt.Top

For i = 1 To 4

Controls("Btnt" & i).Left = Btn0.Left+300

Controls("Btnt" & i).Top = b + Controls("Btnt" & i).Height * i

Btn = Controls("Btnt" & i).Top

Next

End Function

چنانچه هر یک Toppadding خودش را داشته باشه فرضا بین باتن های سمت راست هر کدام فواصل متغیری باشد باید آنها را هم در نظر بگیرید ولی معمولا باتن ها را بهم بچسبانید تا نیاز به کد نویسی اضافه تری نباشد.

در رویداد کلیک Btn0 میتوان نوشت که اولا Btnt ها زیر آن بیاید و Btn1 و Btn2 در زیر Btnt ها قرار گیرد 

()Private Sub Btn0_Click

Btn1.Top = Btn(Btn0) + Btnt4.Height

Btn2.Top = Btn1.Top + Btn1.Height

End Sub

()Private Sub Btn1_Click

Btn1.Top=Btn0.Top+Btn0.Height

(Btn2.Top=Btn(Btn1

End Sub 

()Private Sub Btn2_Click

Btn1.Top = Btn0.Top + Btn0.Height

Btn2.Top=Btn1.Top+Btn0.Height

(Call Btn(Btn2

End Sub

تست شده طبق فایل GIF زیر ، نام ها در کپشن باتن ها نوشته شد تا گیج کننده نباشد.

The &H prefix denotes a number represented in hexadecimal (base 16) notation.

Hexadecimal digits, like decimal, start at 0, but go up to 

.(F (16

In C-based languages hexadecimal numbers are prefixed with 0x, eg. 0x10000. This is directly equal to

GWL_USERDATA

When you send a WM_CLOSE message to a window, it tries to close the window as if the X button were pressed.You cannot know whether the application was closed externally or by clicking the X button

But there is an easy alternative. When you are closing the window externally using WM_CLOSE, you can initialize its 32-bit user data value using the SetWindowLong function before sending the message. In the target application (being closed) you will query this user data using GetWindowLong function and execute your code accordingly.

The user data value is set to 0 by default. You can set it to any non-zero value before sending the WM_CLOSE 

.message

The WM_PAINT message is sent when the system or another application makes a request to paint a portion 

  of an application's window

The PAINTSTRUCT structure contains information that can be used to paint the.client area of a window

The idea is to add your own Windows message handler, you can do this using

Don't forget : Before terminating, an application must call the UnhookWindowsHookEx function to free
