How To Create An On-screen Shape (circle) That Has A Fill Color, Which Will Blink Every X Seconds

Jun 8, 2011

I need to create an on-screen shape (circle) that has a fill color, which will blink every X seconds (go from fill color, to white, back to fill color). This is trivial to do...BUT... i want to do it in my own class, so that I can instantiate it numerous times passing it unique coordinates for each instantiation.

How do I do it? Can a class have its own "timer control" in it independent from the form? How would I draw a shape from a class?

Cursors (.cur) Only Render In Black And White - How To Make Them Color

Jun 5, 2009

I am using the cursor converter to set both

dim cCon as cursorconverter = new cursorconverter
me.cursor = cursorconverter.ConvertFrom(myCursor.cur)

and

windows.forms.cursor.current = cursorconverter.ConvertFrom(myCursor.cur)

the reason for setting both is that otherwise the cursor will not always have the desired appearance. I know that cursors can be rendered in color, like 3D-Bronze, windows animated, hands and variations.

Asp.net - After Resizing White Image Gets Gray Border?

Jul 25, 2011

i was searching google for some kind solution and i found one, i tried to implement it in my code but it doesn't work. The problem is that after resizing white images they gets gray border.Here is the link of soloution i found:It says:

This problem is occuring because you are interpolating your image data to a new size, but along the edges there are no pixels to interpolate and .NET uses black pixels for these edges by default. To fix this you need to use an ImageAttributes class in your DrawImage call....

https:[url].....

CODE 1: And this is my code WITH IMPLEMENTATION OF ImageAttributes:

Private Shared Function ResizeImageFile(ByVal imageFile As Byte(), ByVal targetSize As Integer) As Byte()

Using oldImage As System.Drawing.Image = System.Drawing.Image.FromStream(New MemoryStream(imageFile))

Dim newSize As Size = CalculateDimensions(oldImage.Size, targetSize)[code].......
