Adjusting Form Size According To Screen Display
Nov 25, 2010I've a form set to size 1240:750. On my PC where I've VB2010 installed, the screen size is set to 1680:1024 and the form can be viewed fine but on a PC with screen size set to 1280:1024 (higher than the form) the form in question is cropped almost a third of it. To adjust the form to everyone screen size I set the below code at load with no avail.
'Autosize form to screen
Me.Height = (SystemInformation.PrimaryMonitorSize.Height) * (0.9)
Me.Width = (SystemInformation.PrimaryMonitorSize.Width) '* (0.9)
Me.MaximumSize = New System.Drawing.Size(Me.Width, Me.Height)
Me.MinimumSize = New System.Drawing.Size(1240, 750)

View 8 RepliesGet The First/last/min/max Logical Item Of A List?
Dec 17, 2010Sorting arrays are useful when you want to get the first/last/min/max logical item of a list. I.E. A list that contains numbers and you want to find the Min/Max (without LINQ), you can sort the list and pull the first/last element. It's also useful to display lists to the user in alphabetical order.
View 2 RepliesLogical And Bitwise Operators?

View 2 RepliesLinq - .NET Logical Expression Evaluator?
May 21, 2010I need to test a logical expression held in a string to see if it evaluate to TRUE or FALSE.(the strig is built dynamically)For example the resulting string may contain "'dog'<'cat' OR (1>4 AND 4<6)". There are no variables in the string, it will logically evaluate. It will only contain simple operators = > < >< >= <= and AND , OR and Open and Close Brackets, string constants and numbers. (converted to correct syntax && || etc.)
I currently acheive this by creating a jscipt function and compiling it into a .dll. I then reference the .dll in my VB.NET project.
class ExpressionEvaluator
{
function Evaluate(Expression : String)
{
return eval(Expression);
}
}
Is there a simpler method using built in .NET functions or Lamdba expressions.

Storing Conditional (Logical Structures) In XML
Jan 20, 2009I have the need to express simple conditionals as program input. The input must be human readable. Is XML suited for this? For example, I have the following conditional statement:
If AnimalType = Leopard And (SourceCountry = Kenya Or TargetCountry = Kenya) Then
ZooKeeper=Jack
Else
ZooKeeper=Jill
End If
Expressing the above in XML might look something like this:
<If>
<Conditional>
<And>
<AnimalType>Leopard<AnimalType>
[Code] .....
How best to represent conditional statements in XML? I haven't yet explored using attributes. I don't currently have the need for nested 'If' statements or the 'Else If' clause, but I'm going to try and work them in anyway. Perhaps the VB code is more 'readable' than XML can be in this case and I should create a custom flat-file format instead.
