I am trying to do a do while loop to make a circle draw itself resized by 1 each time 50 times. I just dont know how to define the numbers that make up the circle size properties. here is my simple code
Me.CreateGraphics.DrawEllipse(pencolor, 135, 125, 5, 5)
I would like to just make a simple do while loop to adjust the 5,5 by +1. I am really new to programming and any help will be excelent. If I knew the property name of the 2 numbers I need to change I could declare them as a letter H & W and just do while
H,W is < 56
H+1
W+1
if this makes any sense?

Any explanation why a EXE in VS2005 would grow from 9MB to 17MB. The only thing changed between the 2 compiles as the adding of about 20 lines of code and an additional Crystal Report file (.rpt). The .rpt is about 8.5MB, but our understanding is that the .rpt doesn't get included in the EXE.

Write a program that allows the user to endter the current populations of the states into an array of text boxes, and gives the percentage growth for the collection of five states. The growth is calculated with the formula: Growth = (projected pop - current pop) / current pop

View 3 RepliesI have a issue in a serialization process. I'm trying to Serialize a part of a bigger class.
I've a Class named MyBigClass with contain many property and method, and some of them may not be Serializable.
And I'm trying to Serialize one property of the MyBigClass class, witch is a SortedList named SubClassXList defined as SortedList(Int32, ClassX)
My problem is when it is time to serialize the SortedList (SubClassXList) a error tell me that a Class (say Class B) could not be Serialized because it is not marked as "Serializable", but the Class B in question have nothing to do with the SubClassXList in question.
The only thing I could see, is that the Serialization method try to also Serialize the Main Class (MyBigClass).
Here is the method that I use to Clone a Object ClassX do have the attribute "Serializable()"
Public Function CloneObject(ByVal pObjectToSerialize As Object) As Object

I'm trying to stack a few lists on top of each other. But the label.size.height appears to be bigger then the label itself. When i set the borderstyle to fixedsingle, i see the border around the text. But the height is bigger, so there comes a space between one label and the next. I have tried to set margin and padding to 0 without result. Exemple: label.size.height return 23, when the height actually is something around 15. Does someone knows how i get the right size? Edit: When i explicitly set the height of the lable, the problem is solved. Is this some problem with autosize?

That allows all the columns in my DataGridView to be resizable EXCEPT the last column.

I'm wondering, what happens when you do following:
Collection.Insert(55, "Input")
The collection contains 20 items, so 19 would be the last index. This doesn't work, I get the expected outofrangeException. But when I do :
Collection.Insert(20, "Input")
That works without a problem, even though it is 1 out of the collection.
