Random Numbers Displayed Instead Of Stored Integer?
Mar 12, 2012I've used a numericupdown to select a number and then save it to a .dat file
When i try to display the integer in a listbox, it appears as a random sequence of numbers.
for example, if i input 200 into the numbericupdown, when displayed in the listbox, it is shown as 538976366
Is it an error with the properties with either the numericupdown or the listbox? or do you need to see my code?
let me know if you need any more information or code

View 4 RepliesManipulate A DataGridView Control When It's Name Is Stored As A Variable?
Oct 9, 2010I have a number of tabpages that each contain a datagridview control only. Based on the results of a SQL statement I then loop through each tabpage and set its name. The reason for this is that at runtime (and depending on the results of the SQL statement), the contents of each tab page will change - henceI loop through the tabpages and set the name/ text (to reflect what will later be shown in the DataGridView)
The datagridview control on each tab has the default name e.g. DataGridView1, DataGridView2, DataGridView3 so it's easy for me to loop through them e.g.:
for i as integer = 1 to 3

View 2 RepliesVS 2005 - Length Of Array Is Integer Variable
Apr 26, 2009I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration
Dim array1 (2, integer) as string
Public Sub
integer = 5
End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.

Aug 19, 2011Is there anyway to customize a variable to use both an integer and a boolean value?For example. I am kind of making a simulation engine and using GDI as a visual aid, I am generating a grid of tiles for objects to be displayed, but I do NOT want to repaint all the tiles just the ones that have changed, so that I can save fps.So I thought if I could set a variable for the "tile number", "how many objects there are on a tile", and a boolean value for whether or not the tile needs repainted.[code]

Convert String To Integer With Variable Decimal Sign?
Nov 22, 2011I am currently looking into the conversion of a string value to an integer. Obviously I will need to do some validation as to whether the passed value is in fact convertible to an integer.
At the heart of my question is this: the users' local is nl-BE (dutch (Belgium)), which means that we use a comma as decimal sign (and points as thousands separator); e.g. 123.456,78 would be a valid nl-BE number. Now, when using the numeric keypad, the
decimal key will yield a point, not a comma (weird huh!). So many user will enter 123456.12 and when converted to an Int, this should yield 123456.
The thing is that I want to cover all possible angles; both points and commas may be used as decimal sign by the users. So I wondering if anyone has written some code that deals with such a situation. I was thinking of an extension method that makes the
conversion based on whether a point or a comma is last used in the passed string (since no thousands separators should occur after the decimal sign).
Crossover From Vb6 - Rtlmovememory - Copy Bytes Of Integer To A Variable
