OutOfMemoryException On Bitmap.Clone Method?
Mar 23, 2010Are there other conditions that can cause this exception to be raised? I am attempting to use the method to take a section of the source bitmap in question (possibly equal to the entire source bitmap). I have checked my code extensively, including verifying the parameters of the Rectangle at runtime, and even tried hard-coding a Rectangle with parameters that I knew were within the bounds of the source bitmap, but have still received the error. I tried several choices for the PixelFormat as well.
View 6 RepliesWhy Does One Method Of Declaring A Bitmap Work And The Other Doesn't
May 27, 2009I can't figure this out. I have a bitmap that will be used throughout an application, so I can't declare it with a Dim statement in a procedure, or it isn't recognized as having been declared in other procedures. So I declared it at the top of the form class, two ways. This one works: Private MyBitmap As New Bitmap(622, 461) It makes a bitmap to the exact size of a picturebox I have. But I want to be able to change the size of the picturebox and not have to worry about going back into this declaration to set things up, every time I decide to change the box's dimensions. So I tried this next version, but it doesn't work:

Clone And MemberwiseClone ?
Aug 31, 2009There is something that I do not understand the point of, and it has to do with ICloneable.
Take the simple example below:

Private p_List As New List(Of String)
Private p_Number As Double

No... For the life of me I cannot understand why anyone would want a Shallow copy of anything.... And... I do not understand why the Me.MemberwiseClone would not work with list and arrays....

oh and also the panels may not be the same size ... so in this case the result would need to be "stretched" or "shrunk"

.net - OutOfMemoryException With Image.Clone - Only On Windows 2003?
Mar 23, 2010I have an image that I need to shrink. The original image is a grayscale PNG, which isn't a huge issues except that when I shrink it down, the thermal label printers pickup the artifacts and print them on the label. So, what I did was change the image to black & white (Format1bppIndexed) before resizing, like this:
Dim bte() As Byte = System.Convert.FromBase64String(imgStr)
Dim ms As New IO.MemoryStream(bte)
Dim bmp As New System.Drawing.Bitmap(ms)
[code]....
And then I resize it. This code works fine on my Windows 7 machine, but when I run it on the Windows 2003 Server box that it calls home, it always throws an OutOfMemoryException when it hits the bmp.Clone line.

Simple 2D 'Space Invaders' Clone In Silverlight
Mar 17, 2011I want to make a simple 2d game in Silverlight, but it seems like things have changed since the last time I tried to make a game using mode 13h graphics. Can someone give me a run-down of how you'd go about it.I just mean at a high-level, focusing on the silverlight-specific aspects; not general game design.A fictional example might be:'The main game loop shouldn't be a loop, use a DispatchTimer instead. Use a Canvas as the main drawing object; but realize that we don't bother drawing individual pixels - all of your in-game objects should be represented by controls. Be sure to set the 'UseHardwareFlag' to true'.
