.NET – Flashing and “CreateParams”

Protected Overrides ReadOnly Property CreateParams() As CreateParams
 Get
 Dim cp As CreateParams = MyBase.CreateParams
 cp.ExStyle = cp.ExStyle Or &H2000000< br /> Return cp
 End Get
End Property'CreateParams

UPDATE:

I want to avoid flickering in my application panel, after a Google search 4 months ago, after trying the subclassed panel, after asking two or three times, in other forums After asking in…No one has a solution, but today I found a miraculous solution in the last answer: Is their a way to stop the picturebox from flickering when being resized?

Protected Overrides ReadOnly Property CreateParams() As CreateParams
 Get
 Dim cp As CreateParams = MyBase.CreateParams
 cp.ExStyle = cp.ExStyle Or &H2000000
 Return cp
 End Get
End Property'CreateParams

Now I want to know what those lines of code are. I need to understand what code my application is doing,

< p>Is it a good way to avoid flickering?

MSDN says:

“CreateParams should not be overridden and used to adjust the properties of derived controls”

But why not? , This is the only way I found to really make my panel flash, so that’s why I want to know more about the code I posted above, I want to know all the orders, also the benefits and denials of the sub-orders, welcome Everything…

Can someone explain this code to me?

UPDATE:

I have tested the “flicker solution” in all my applications, yes, it is a flicker solution …But there are negative factors’ because my program speed is -200% slower, I mean when using that overlay subroutine it turns very slowly, such as x6 times slower, so using an overlay is not a good idea.

Does anyone know if I can avoid flickering without making my application stupid?

Each time you redraw a control, you also need to redraw the background; your application may not declare the operation of the resource to be completed. You are using The solution basically sets a flag to indicate that you want your form and all its drawn content to be double-buffered. You can use this to consume unnecessary resources.
Instead, you can resize the image Set the double buffered property to true on each object in the .
Computer resources are limited, and you should reserve as much as possible. This is why Microsoft has booked so many parameters and resource release procedures.

Edit: By default, PictureBox is double-buffered to handle the onpaint event. You still need to use double-buffer on the background object.
